171-477: A battleship is a large, heavily armored warship with a main battery consisting of large- caliber guns , designed to serve as capital ships with the most intense firepower . Before the rise of supercarriers , battleships were among the largest and most formidable weapon systems ever built. The term battleship came into use in the late 1880s to describe a type of ironclad warship , now referred to by historians as pre-dreadnought battleships . In 1906,

342-512: A British victory. The German strategy was therefore to try to provoke an engagement on their terms: either to induce a part of the Grand Fleet to enter battle alone, or to fight a pitched battle near the German coastline, where friendly minefields, torpedo-boats and submarines could be used to even the odds. This did not happen, however, due in large part to the necessity to keep submarines for

513-399: A bullet that fits the barrel as opposed to one which does not, such as the shrapnel shooting fire lance . As such, the fire lance, which appeared between the 10th and 12th centuries AD, as well as other early metal barrel gunpowder weapons have been described as "proto-guns" Joseph Needham defined a type of firearm known as the "eruptor," which he described as a cross between a fire lance and

684-460: A copper base that incorporated a primer pellet. While rifled guns did exist prior to the 19th century in the form of grooves cut into the interior of a barrel, these were considered specialist weapons and limited in number. The rate of fire of handheld guns began to increase drastically. In 1836, Johann Nicolaus von Dreyse invented the Dreyse needle gun , a breech-loading rifle which increased

855-440: A gun, as a "proto-gun" for the same reason. He defined a fully developed firearm, a "true gun," as possessing three basic features: a metal barrel, gunpowder with high nitrate content, and a projectile that occluded the barrel. The "true gun" appears to have emerged in late 1200s China, around 300 years after the appearance of the fire lance. Although the term "gun" postdates the invention of firearms, historians have applied it to

1026-526: A heavily armoured central citadel, with relatively unarmoured ends; however, by the era of HMS  Dreadnought , battleships were armoured over the length of the ship with varying zones of heavy, moderate or light armour. The U.S. Navy adopted what was formally called "all or nothing" armour in the Standard-type battleships , starting with the Nevada class laid down in 1912. "All or nothing" armour

1197-598: A large block superstructure nicknamed the "Queen Anne's castle", such as in Queen Elizabeth and Warspite , which would be used in the new conning towers of the King George V -class fast battleships . External bulges were added to improve both buoyancy to counteract weight increase and provide underwater protection against mines and torpedoes. The Japanese rebuilt all of their battleships, plus their battlecruisers, with distinctive " pagoda " structures, though

1368-448: A less important role than had been expected in that conflict. The value of the battleship has been questioned, even during their heyday. There were few of the decisive fleet battles that battleship proponents expected and used to justify the vast resources spent on building battlefleets. Even in spite of their huge firepower and protection, battleships were increasingly vulnerable to much smaller and relatively inexpensive weapons: initially

1539-610: A mechanical bolt throwing weapon of enormous size, mounted at Windsor Castle during the 14th century. This name in turn may have derived from the Old Norse woman's proper name Gunnhildr which combines two Norse words referring to battle. "Gunnildr", which means "War-sword", was often shortened to "Gunna". The earliest recorded use of the term "gonne" was in a Latin document c.  1339 . Other names for guns during this era were "schioppi" (Italian translation-"thunderers"), and "donrebusse" (Dutch translation-"thunder gun") which

1710-590: A mine laid by a German U-boat in October 1914 and sank. The threat that German U-boats posed to British dreadnoughts was enough to cause the Royal Navy to change their strategy and tactics in the North Sea to reduce the risk of U-boat attack. Further near-misses from submarine attacks on battleships and casualties amongst cruisers led to growing concern in the Royal Navy about the vulnerability of battleships. As

1881-483: A mine laid by friendly forces, and sank with little loss of life. In May 1937, Jaime I was damaged by Nationalist air attacks and a grounding incident. The ship was forced to go back to port to be repaired. There she was again hit by several aerial bombs. It was then decided to tow the battleship to a more secure port, but during the transport she suffered an internal explosion that caused 300 deaths and her total loss. Several Italian and German capital ships participated in

2052-568: A mixed-caliber secondary battery amidships around the superstructure. An early design with superficial similarity to the pre-dreadnought is the British Devastation class of 1871. The slow-firing 12-inch (305 mm) main guns were the principal weapons for battleship-to-battleship combat. The intermediate and secondary batteries had two roles. Against major ships, it was thought a 'hail of fire' from quick-firing secondary weapons could distract enemy gun crews by inflicting damage to

2223-418: A naval arms race with bigger, more heavily armed and armoured ironclads. Early experiments showed that wrought iron was superior to cast iron , and wrought iron was subsequently adopted for naval use. British efforts at perfecting iron armour were headed by a government Special Committee on Iron, formed in 1861 by War Secretary Lord Herbert for the continued research into naval armour. Among its members

2394-544: A naval engagement. The introduction of steam accelerated the growth in size of battleships. France and the United Kingdom were the only countries to develop fleets of wooden steam screw battleships although several other navies operated small numbers of screw battleships, including Russia (9), the Ottoman Empire (3), Sweden (2), Naples (1), Denmark (1) and Austria (1). The adoption of steam power

2565-647: A new naval arms race. Three major fleet actions between steel battleships took place: the long-range gunnery duel at the Battle of the Yellow Sea in 1904, the decisive Battle of Tsushima in 1905 (both during the Russo-Japanese War ) and the inconclusive Battle of Jutland in 1916, during the First World War . Jutland was the largest naval battle and the only full-scale clash of dreadnoughts of

2736-666: A part in major engagements in Atlantic, Pacific and Mediterranean theaters; in the Atlantic, the Germans used their battleships as independent commerce raiders. However, clashes between battleships were of little strategic importance. The Battle of the Atlantic was fought between destroyers and submarines, and most of the decisive fleet clashes of the Pacific war were determined by aircraft carriers . Naval armour Naval armour consists of many different designs, depending on what

2907-439: A pellet wad that filled the barrel was recorded to have been used as a fire lance projectile, making it the first recorded bullet in history. With this, the three basic features of a gun were put in place: a barrel made of metal, high- nitrate gunpowder, and a projectile which totally occludes the muzzle so that the powder charge exerts its full potential in propellant effect. The metal barrel fire lances began to be used without

3078-698: A possible Pacific war , the United States was keen to conclude the Washington Naval Treaty of 1922. This treaty limited the number and size of battleships that each major nation could possess, and required Britain to accept parity with the U.S. and to abandon the British alliance with Japan. The Washington treaty was followed by a series of other naval treaties, including the First Geneva Naval Conference (1927),

3249-414: A projectile." Gunpowder and firearm historian Kenneth Chase defines "firearms" and "guns" in his Firearms: A Global History to 1700 as "gunpowder weapons that use the explosive force of the gunpowder to propel a projectile from a tube: cannons, muskets, and pistols are typical examples." According to Tonio Andrade , a historian of gunpowder technology, a "true gun" is defined as a firearm which shoots

3420-458: A result armor declined, which also made the heavy musket obsolete. Although there is relatively little to no difference in design between arquebus and musket except in size and strength, it was the term musket which remained in use up into the 1800s. It may not be completely inaccurate to suggest that the musket was in its fabrication simply a larger arquebus. At least on one occasion the musket and arquebus have been used interchangeably to refer to

3591-480: A ship while the rest of the ship receives significantly less armour. The "all or nothing" concept avoided light or moderate thicknesses of armour: armour was used in the greatest practicable thickness or not at all, thereby providing "either total or negligible protection". Compared to previous armouring systems, "all or nothing" ships had thicker armour covering a smaller proportion of the hull. The ironclad battleship HMS  Inflexible launched in 1876 had featured

3762-535: A similar design in the Bellerophon and St. Vincent classes . An American design, South Carolina , authorized in 1905 and laid down in December 1906, was another of the first dreadnoughts, but she and her sister, Michigan , were not launched until 1908. Both used triple-expansion engines and had a superior layout of the main battery, dispensing with Dreadnought ' s wing turrets. They thus retained

3933-644: A similar type of steel to Ducol in its Pugliese torpedo defence system . This underwater "bulge" system was introduced in the Italian Littorio-class battleships , and in the completely rebuilt versions of the Italian battleship Duilio and the Conte di Cavour-class battleships . The inboard-facing side was consisted of a layer of silicon-manganese high-tensile steel from 28–40 mm (1.1–1.6 in) thick called " Elevata Resistenza " (ER) steel, which

4104-582: A single soldier is the MP 18.1 , invented by Theodor Bergmann . It was introduced into service in 1918 by the German Army during World War I as the primary weapon of the Stosstruppen (assault groups specialized in trench combat). In civilian use, the captive bolt pistol is used in agriculture to humanely stun farm animals for slaughter. The first assault rifle was introduced during World War II by

4275-429: A state of flux. Many ironclads were built to make use of the ram or the torpedo , which a number of naval designers considered the crucial weapons of naval combat. There is no clear end to the ironclad period, but towards the end of the 1890s the term ironclad dropped out of use. New ships were increasingly constructed to a standard pattern and known as battleships, protected cruisers or armoured cruisers . In turn

4446-484: A symbol of naval dominance and national might, and for decades were a major intimidation factor for power projection in both diplomacy and military strategy . A global arms race in battleship construction began in Europe in the 1890s and culminated at the decisive Battle of Tsushima in 1905, the outcome of which significantly influenced the design of HMS Dreadnought . The launch of Dreadnought in 1906 commenced

4617-461: A triple-bottom. The innermost bulkhead is commonly referred to as the holding bulkhead , and often this bulkhead would be manufactured from high tensile steel that could deform and absorb the pressure pulse from a torpedo hit without breaking. If the final bulkhead was at least 37 mm thick, it may also be referred to as an armoured bulkhead , as it would be capable of stopping splinters and shells with low striking velocities. The torpedo belt

4788-633: A war scare with France and the build-up of the Russian navy gave added impetus to naval construction, and the British Naval Defence Act of 1889 laid down a new fleet including eight new battleships. The principle that Britain's navy should be more powerful than the two next most powerful fleets combined was established. This policy was designed to deter France and Russia from building more battleships, but both nations nevertheless expanded their fleets with more and better pre-dreadnoughts in

4959-617: A wooden hull, La Gloire , was launched by the French Navy in 1859 prompting the British Royal Navy to build a counter. The following year they launched HMS Warrior , which was twice the size and had 4.5 inches of wrought iron armour (with 18 inches of teak wood backing) over an iron hull. After the first battle between two ironclads took place in 1862 during the American Civil War , it became clear that

5130-402: Is also called a cannon . The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within a barrel tube ( gun barrel ), produced either through the rapid exothermic combustion of propellants (as with firearms ), or by mechanical compression (as with air guns ). The high-pressure gas is introduced behind

5301-402: Is much faster than that of any bullet, and would leave the gun as sound either through the barrel or the bullet itself rather than contributing to the bullet's velocity. Barrel types include rifled —a series of spiraled grooves or angles within the barrel—when the projectile requires an induced spin to stabilize it, and smoothbore when the projectile is stabilized by other means or rifling

5472-410: Is often held that these engagements demonstrated the importance of the 12-inch (305 mm) gun over its smaller counterparts, though some historians take the view that secondary batteries were just as important as the larger weapons when dealing with smaller fast-moving torpedo craft. Such was the case, albeit unsuccessfully, when the Russian battleship  Knyaz Suvorov at Tsushima had been sent to

5643-421: Is undesired or unnecessary. Typically, interior barrel diameter and the associated projectile size is a means to identify gun variations. Bore diameter is reported in several ways. The more conventional measure is reporting the interior diameter (bore) of the barrel in decimal fractions of the inch or in millimetres. Some guns—such as shotguns —report the weapon's gauge (which is the number of shot pellets having

5814-634: The Hiei received a more modern bridge tower that would influence the new Yamato class . Bulges were fitted, including steel tube arrays to improve both underwater and vertical protection along the waterline. The U.S. experimented with cage masts and later tripod masts , though after the Japanese attack on Pearl Harbor some of the most severely damaged ships (such as West Virginia and California ) were rebuilt with tower masts, for an appearance similar to their Iowa -class contemporaries. Radar, which

5985-737: The King George V class . It was in the Mediterranean that navies remained most committed to battleship warfare. France intended to build six battleships of the Dunkerque and Richelieu classes , and the Italians four Littorio -class ships. Neither navy built significant aircraft carriers. The U.S. preferred to spend limited funds on aircraft carriers until the South Dakota class . Japan, also prioritising aircraft carriers, nevertheless began work on three mammoth Yamato s (although

6156-757: The First London Naval Treaty (1930), the Second Geneva Naval Conference (1932), and finally the Second London Naval Treaty (1936), which all set limits on major warships. These treaties became effectively obsolete on September 1, 1939, at the beginning of World War II , but the ship classifications that had been agreed upon still apply. The treaty limitations meant that fewer new battleships were launched in 1919–1939 than in 1905–1914. The treaties also inhibited development by imposing upper limits on

6327-464: The Gulf War in 1991, and then struck from the U.S. Naval Vessel Register in the 2000s. Many World War II-era American battleships survive today as museum ships . A ship of the line was a large, unarmored wooden sailing ship which mounted a battery of up to 120 smoothbore guns and carronades , which came to prominence with the adoption of line of battle tactics in the early 17th century and

6498-581: The Henry rifle , the first reliable repeating rifle . An improved version of the Henry rifle was developed by Winchester Repeating Arms Company in 1873, known as the Model 1873 Winchester rifle . Smokeless powder was invented in 1880 and began replacing gunpowder , which came to be known as black powder. By the start of the 20th century, smokeless powder was adopted throughout the world and black powder, what

6669-464: The Mongol prince Nayan . The History of Yuan records that the cannons of Li Ting's soldiers "caused great damage" and created "such confusion that the enemy soldiers attacked and killed each other." The hand cannons were used again in the beginning of 1288. Li Ting's "gun-soldiers" or chongzu ( 銃卒 ) carried the hand cannons "on their backs". The passage on the 1288 battle is also the first to use

6840-978: The Portuguese introduced matchlocks which were known as tanegashima to the Japanese. Gunpowder technology entered Java in the Mongol invasion of Java (1293 A.D.). Majapahit under Mahapatih (prime minister) Gajah Mada utilized gunpowder technology obtained from the Yuan dynasty for use in the naval fleet. During the following years, the Majapahit army have begun producing cannons known as cetbang . Early cetbang (also called Eastern-style cetbang) resembled Chinese cannons and hand cannons. Eastern-style cetbangs were mostly made of bronze and were front-loaded cannons. It fires arrow-like projectiles, but round bullets and co-viative projectiles can also be used. These arrows can be solid-tipped without explosives, or with explosives and incendiary materials placed behind

7011-620: The Royal Navy was able to use her imposing battleship and battlecruiser fleet to impose a strict and successful naval blockade of Germany and kept Germany's smaller battleship fleet bottled up in the North Sea : only narrow channels led to the Atlantic Ocean and these were guarded by British forces. Both sides were aware that, because of the greater number of British dreadnoughts, a full fleet engagement would be likely to result in

7182-399: The Royal Navy , anxious to prevent France from gaining a technological lead. The superior armored frigate Warrior followed Gloire by only 14 months, and both nations embarked on a program of building new ironclads and converting existing screw ships of the line to armored frigates. Within two years, Italy, Austria, Spain and Russia had all ordered ironclad warships, and by the time of

7353-579: The Silk Road through the Middle East. Hasan al-Rammah had already written about fire lances in the 13th century, so proto-guns were known in the Middle East at that point. Another theory is that it was brought to Europe during the Mongol invasion in the first half of the 13th century. The earliest depiction of a cannon in Europe dates to 1326 and evidence of firearm production can be found in

7524-483: The US Civil War used laminated armour but this was necessitated by lack of facilities for manufacturing single plates of proper thickness. Due to the ever increasing thickness of the armour, and the associated weight, proposals were made from an early date to faceharden the iron or weld steel plates to the front face of iron armour. Efforts to carry out these proposals failed for many reasons, primarily because

7695-406: The alloy for additional hardness . Also, while Harveyized armour was carburized by heating the steel and placing charcoal on its surface for long periods (often several weeks), Krupp armour went a step further. Instead of inefficiently introducing carbon at the surface with coal, Krupp armour achieved greater depth of carbon cementation by applying carbon-bearing gases to the heated steel. Once

7866-467: The metallurgy at the time was not up to the task. By the mid-to-late 1870s, iron armour started to give way to steel armour , which promised to reduce the thickness, and therefore the weight, of the armour. Harvey armor was a type of steel armor developed in the early 1890s in which the front surfaces of the plates were case hardened . The method for doing this was known as the Harvey process, and

8037-588: The torpedo and the naval mine , and later attack aircraft and the guided missile . The growing range of naval engagements led to the aircraft carrier replacing the battleship as the leading capital ship during World War II, with the last battleship to be launched being HMS  Vanguard in 1944. Four battleships were retained by the United States Navy until the end of the Cold War for fire support purposes and were last used in combat during

8208-531: The "all-big-gun" concept. During the Battle of the Yellow Sea on August 10, 1904, Admiral Togo of the Imperial Japanese Navy commenced deliberate 12-inch gun fire at the Russian flagship Tzesarevich at 14,200 yards (13,000 meters). At the Battle of Tsushima on May 27, 1905, Russian Admiral Rozhestvensky's flagship fired the first 12-inch guns at the Japanese flagship Mikasa at 7,000 meters. It

8379-498: The "unsinkable" German World War I battleship SMS  Ostfriesland and the American pre-dreadnought Alabama . Although Mitchell had required "war-time conditions", the ships sunk were obsolete, stationary, defenseless and had no damage control. The sinking of Ostfriesland was accomplished by violating an agreement that would have allowed Navy engineers to examine the effects of various munitions: Mitchell's airmen disregarded

8550-473: The 1480s show little difference and surprising similarity with cannons later in the 1750s. This 300-year period during which the classic gun dominated gives it its moniker. The "classic gun" has also been described as the "modern ordnance synthesis." Gunpowder was invented in China during the 9th century. The first firearm was the fire lance , which was invented in China between the 10–12th centuries. It

8721-406: The 1860s and 1870s, but steel armor began to take over because it was stronger, and thus less could be used. The technology behind steel armour went from simple carbon steel plates, to increasingly complex arrangements with variable alloys. Case-hardened Harvey armor was the first major development, followed by chromium alloyed and specially hardened Krupp armour . Ducol steel came into use in

8892-458: The 1866 Battle of Lissa , where the modern Austrian steam two-decker SMS  Kaiser ranged across a confused battlefield, rammed an Italian ironclad and took 80 hits from Italian ironclads, many of which were shells, but including at least one 300-pound shot at point-blank range. Despite losing her bowsprit and her foremast, and being set on fire, she was ready for action again the very next day. The development of high-explosive shells made

9063-449: The 1890s. In the last years of the 19th century and the first years of the 20th, the escalation in the building of battleships became an arms race between Britain and Germany . The German naval laws of 1890 and 1898 authorized a fleet of 38 battleships, a vital threat to the balance of naval power. Britain answered with further shipbuilding, but by the end of the pre-dreadnought era, British supremacy at sea had markedly weakened. In 1883,

Early ship armour probably had its origins in applying thin sheets of metal to ship undersides for preservative reasons. There are only a few exceptional examples of ships equipped with metal armor before Industrial Revolution . The Finis Belli

9405-418: The 19th century led to the development of modern guns. In 1815, Joshua Shaw invented percussion caps , which replaced the flintlock trigger system. The new percussion caps allowed guns to shoot reliably in any weather condition. In 1835, Casimir Lefaucheux invented the first practical breech loading firearm with a cartridge . The new cartridge contained a conical bullet, a cardboard powder tube, and

9576-747: The 8-inch battery being completely unusable, and the inability to train the primary and intermediate armaments on different targets led to significant tactical limitations. Even though such innovative designs saved weight (a key reason for their inception), they proved too cumbersome in practice. In 1906, the British Royal Navy launched the revolutionary HMS  Dreadnought . Created as a result of pressure from Admiral Sir John ("Jackie") Fisher , HMS Dreadnought rendered existing battleships obsolete. Combining an "all-big-gun" armament of ten 12-inch (305 mm) guns with unprecedented speed (from steam turbine engines) and protection, she prompted navies worldwide to re-evaluate their battleship building programs. While

9747-617: The Atlantic campaign. Submarines were the only vessels in the Imperial German Navy able to break out and raid British commerce in force, but even though they sank many merchant ships, they could not successfully counter-blockade the United Kingdom; the Royal Navy successfully adopted convoy tactics to combat Germany's submarine counter-blockade and eventually defeated it. This was in stark contrast to Britain's successful blockade of Germany. The first two years of war saw

The Hachiman Gudoukun of 1360 mentions iron pao "which caused a flash of light and a loud noise when fired." The Taiheki of 1370 mentions "iron pao shaped like a bell." The exact nature of the spread of firearms and its route is uncertain. One theory is that gunpowder and cannons arrived in Europe via

10089-553: The British and French blockade. And in the Mediterranean , the most important use of battleships was in support of the amphibious assault on Gallipoli . In September 1914, the threat posed to surface ships by German U-boats was confirmed by successful attacks on British cruisers, including the sinking of three British armored cruisers by the German submarine SM  U-9 in less than an hour. The British Super-dreadnought HMS  Audacious soon followed suit as she struck

10260-530: The British fleet. Less than two months later, the Germans once again attempted to draw portions of the Grand Fleet into battle. The resulting Action of 19 August 1916 proved inconclusive. This reinforced German determination not to engage in a fleet to fleet battle. In the other naval theatres there were no decisive pitched battles. In the Black Sea , engagement between Russian and Ottoman battleships

10431-633: The Dardanelles Campaign and the destruction of the Austro-Hungarian dreadnought SMS  Szent István by Italian motor torpedo boats in June 1918. In large fleet actions, however, destroyers and torpedo boats were usually unable to get close enough to the battleships to damage them. The only battleship sunk in a fleet action by either torpedo boats or destroyers was the obsolescent German pre-dreadnought SMS  Pommern . She

The inter-war period saw the battleship subjected to strict international limitations to prevent a costly arms race breaking out. While the victors were not limited by the Treaty of Versailles, many of the major naval powers were crippled after the war. Faced with the prospect of a naval arms race against the United Kingdom and Japan, which would in turn have led to

10773-451: The Germans, known as the StG44 . It was the first firearm to bridge the gap between long range rifles, machine guns, and short range submachine guns. Since the mid-20th century, guns that fire beams of energy rather than solid projectiles have been developed, and also guns that can be fired by means other than the use of gunpowder. Most guns use compressed gas confined by the barrel to propel

The Treaty of Versailles specified that the ships should be handed over to the British. Instead, most of them were scuttled by their German crews on June 21, 1919, just before the signature of the peace treaty. The treaty also limited

11115-423: The Japanese had laid down an all-big-gun battleship, Satsuma , in 1904 and the concept of an all-big-gun ship had been in circulation for several years, it had yet to be validated in combat. Dreadnought sparked a new arms race , principally between Britain and Germany but reflected worldwide, as the new class of warships became a crucial element of national power. Technical development continued rapidly through

11286-588: The Moray Firth. Whilst the escape of the German fleet from the superior British firepower at Jutland was effected by the German cruisers and destroyers successfully turning away the British battleships, the German attempt to rely on U-boat attacks on the British fleet failed. Torpedo boats did have some successes against battleships in World War I, as demonstrated by the sinking of the British pre-dreadnought HMS  Goliath by Muâvenet-i Millîye during

11457-588: The North Sea were battles including the Heligoland Bight and Dogger Bank and German raids on the English coast, all of which were attempts by the Germans to lure out portions of the Grand Fleet in an attempt to defeat the Royal Navy in detail. On May 31, 1916, a further attempt to draw British ships into battle on German terms resulted in a clash of the battlefleets in the Battle of Jutland . The German fleet withdrew to port after two short encounters with

It originally described a hand cannon with a lug or hook on the underside for stabilizing the weapon, usually on defensive fortifications. In the early 1500s, heavier variants known as " muskets " that were fired from resting Y-shaped supports appeared. The musket was able to penetrate heavy armor, and as

Thus each side had one battleship; however, the Republican Navy generally lacked experienced officers. The Spanish battleships mainly restricted themselves to mutual blockades, convoy escort duties, and shore bombardment, rarely in direct fighting against other surface units. In April 1937, España ran into

11970-501: The Royal Navy's battleships and battlecruisers regularly "sweep" the North Sea making sure that no German ships could get in or out. Only a few German surface ships that were already at sea, such as the famous light cruiser SMS  Emden , were able to raid commerce. Even some of those that did manage to get out were hunted down by battlecruisers, as in the Battle of the Falklands , December 7, 1914. The results of sweeping actions in

Applications have included warship hull construction and light armouring, road bridges, and pressure vessels including locomotive steam boilers and nuclear reactors. Ducol has been used for bulkheads in both general construction and against torpedoes , and for light armour in warships of several countries, including the British , Japanese and perhaps Italian navies. After WW2

12312-527: The Spanish and Portuguese at Zamora. Likewise, the Castilians used arquebuses as well in 1476. Later, a larger arquebus known as a musket was used for breaching heavy armor, but this declined along with heavy armor. Matchlock firearms continued to be called musket. They were used throughout Asia by the mid-1500s. Guns reached their "classic" form in the 1480s. The "classic gun" is so called because of

12483-663: The Special Committee tested both types of plate in 1863, it found that rolled iron was superior to hammered due to greater uniformity in quality. The committee and iron manufacturers worked together on how to more easily produce rolled plate, which became standard use in warships beginning in 1865. The committee addressed the use of wooden backing with iron armour. Early European iron armour consisted of between four and five inches (roughly 10 to 13 cm) of wrought iron backed by between 18 and 36 inches (roughly one-half to one metre) of solid wood . After considerable testing,

12654-495: The U.S. Navy's nascent aircraft carrier program. The Royal Navy , United States Navy , and Imperial Japanese Navy extensively upgraded and modernized their World War I–era battleships during the 1930s. Among the new features were an increased tower height and stability for the optical rangefinder equipment (for gunnery control), more armor (especially around turrets) to protect against plunging fire and aerial bombing, and additional anti-aircraft weapons. Some British ships received

12825-698: The United Kingdom had 38 battleships, twice as many as France and almost as many as the rest of the world put together. In 1897, Britain's lead was far smaller due to competition from France, Germany, and Russia, as well as the development of pre-dreadnought fleets in Italy, the United States and Japan . The Ottoman Empire, Spain, Sweden, Denmark, Norway , the Netherlands , Chile and Brazil all had second-rate fleets led by armored cruisers , coastal defence ships or monitors . Pre-dreadnoughts continued

12996-520: The World Wars, an anti-torpedo bulge involves fitting (or retrofitting) partially water-filled compartmentalized sponsons on either side of a ship's hull, intended to detonate torpedoes, absorb their explosions, and contain flooding to damaged areas within the bulges. All or nothing is a design choice in armouring warships, best known for its employment on Dreadnought battleships . The concept involves concentrating armour on areas most important to

13167-528: The armour is meant to protect against. Sloped armour and belt armour are designed to protect against shellfire ; torpedo belts , bulges , and bulkheads protect against underwater torpedoes or naval mines ; and armoured decks protect against air dropped bombs and long-range shellfire. The materials that make up naval armour have evolved over time, beginning with simply wood, then softer metals like lead or bronze, to harder metals such as iron, and finally steel and composites. Iron armour saw wide use in

13338-440: The armoured deck , the waterline belt , and the transverse bulkheads . Simply sloping a piece of armour inherently increases its effectiveness by increasing the distance a projectile must travel to penetrate it. It also increases the odds that a projectile will ricochet off the target without causing damage. A torpedo bulkhead is common on the more heavily armoured warships , especially battleships and battlecruisers of

13509-557: The bottom by destroyer -launched torpedoes. The 1903–04 design also retained traditional triple-expansion steam engines . As early as 1904, Jackie Fisher had been convinced of the need for fast, powerful ships with an all-big-gun armament. If Tsushima influenced his thinking, it was to persuade him of the need to standardise on 12-inch (305 mm) guns. Fisher's concerns were submarines and destroyers equipped with torpedoes, then threatening to outrange battleship guns, making speed imperative for capital ships . Fisher's preferred option

13680-411: The bullet up to high speed, though devices operating in other ways are sometimes called guns. In firearms the high-pressure gas is generated by combustion, usually of gunpowder . This principle is similar to that of internal combustion engines , except that the bullet leaves the barrel, while the piston transfers its motion to other parts and returns down the cylinder. As in an internal combustion engine,

13851-475: The carburization process was complete, the metal was then transformed into face hardened steel by rapidly heating the cemented face, allowing the high heat to penetrate 30% to 40% of the steel's depth, then quickly quenching first the superheated side then both sides of the steel with powerful jets of either water or oil . Krupp armour was swiftly adopted by the world's major navies; ballistic tests showed that 10.2 in (260 mm) of Krupp armour offered

14022-593: The centerline (one forward, two aft) and two on the wings , giving her at her launch twice the broadside of any other warship. She retained a number of 12-pound (3-inch, 76 mm) quick-firing guns for use against destroyers and torpedo-boats. Her armor was heavy enough for her to go head-to-head with any other ship in a gun battle, and conceivably win. Dreadnought was to have been followed by three Invincible -class battlecruisers, their construction delayed to allow lessons from Dreadnought to be used in their design. While Fisher may have intended Dreadnought to be

14193-468: The chest, tucked under one arm, while the other arm maneuvered a hot pricker to the touch hole to ignite the gunpowder. The Ottomans may have used arquebuses as early as the first half of the 15th century during the Ottoman–Hungarian wars of 1443–1444. The arquebus was used in substantial numbers during the reign of king Matthias Corvinus of Hungary (r. 1458–1490). Arquebuses were used by 1472 by

14364-454: The combustion propagates by deflagration rather than by detonation , and the optimal gunpowder , like the optimal motor fuel, is resistant to detonation. This is because much of the energy generated in detonation is in the form of a shock wave , which can propagate from the gas to the solid structure and heat or damage the structure, rather than staying as heat to propel the piston or bullet. The shock wave at such high temperature and pressure

14535-446: The commissioning of HMS  Dreadnought into the United Kingdom 's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS Dreadnought , were referred to as " dreadnoughts ", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships dominated naval warfare in the late 19th and early 20th centuries, and were

14706-420: The committee found that wood prevented spalling , cushioned the shock of a hit from damaging the structure of the ship and distributed the force over a larger area, which prevented penetration. The drawback of using wood and iron was extreme weight. Experiments with reducing or eliminating wooden backing to save weight proved unsuccessful. The committee also tested steel as potential armour as its members felt that

14877-598: The concept of an all-big-gun battleship in 1903. When the Regia Marina did not pursue his ideas, Cuniberti wrote an article in Jane ' s proposing an "ideal" future British battleship, a large armored warship of 17,000 tons, armed solely with a single calibre main battery (twelve 12-inch [305 mm] guns), carrying 300-millimetre (12 in) belt armor , and capable of 24 knots (44 km/h). The Russo-Japanese War provided operational experience to validate

15048-508: The dreadnought era, with steep changes in armament, armor and propulsion. Ten years after Dreadnought ' s commissioning, much more powerful ships, the super-dreadnoughts, were being built. In the first years of the 20th century, several navies worldwide experimented with the idea of a new type of battleship with a uniform armament of very heavy guns. Admiral Vittorio Cuniberti , the Italian Navy's chief naval architect, articulated

15219-531: The earliest firearms such as the Heilongjiang hand cannon of 1288 or the vase shaped European cannon of 1326. Historians consider firearms to have reached the form of a "classic gun" in the 1480s, which persisted until the mid-18th century. This "classic" form displayed longer, lighter, more efficient, and more accurate design compared to its predecessors only 30 years prior. However this "classic" design changed very little for almost 300 years and cannons of

15390-459: The early 20th century. It is designed to keep the ship afloat even if the hull was struck underneath the belt armour by a shell or by a torpedo . After the lessons learned during World War I , many capital ships were refitted with double, triple, or even quadruple torpedo bulkheads, as well as anti-torpedo bulges to the exterior of the hull. For example, the last US battleship designs during World War II had up to four torpedo bulkheads and

15561-617: The end of World War I, aircraft had successfully adopted the torpedo as a weapon. In 1921 the Italian general and air theorist Giulio Douhet completed a hugely influential treatise on strategic bombing titled The Command of the Air , which foresaw the dominance of air power over naval units. In the 1920s, General Billy Mitchell of the United States Army Air Corps , believing that air forces had rendered navies around

15732-409: The end of the 13th century, they had become "true guns", metal barrel firearms that fired single projectiles which occluded the barrel. Gunpowder and gun technology spread throughout Eurasia during the 14th century. The origin of the English word gun is considered to derive from the name given to a particular historical weapon. Domina Gunilda was the name given to a remarkably large ballista ,

15903-498: The end of the nineteenth century. It was developed by Germany's Krupp Arms Works in 1893 and quickly replaced Harvey armour as the primary method of protecting naval ships, before itself being supplanted by the improved "Krupp cemented armour". The initial manufacturing of Krupp armour was very similar to Harveyized armour; however, while the Harvey process generally used nickel-steel, the Krupp process added as much as 1% chromium to

16074-401: The end of the sailing battleship's heyday in the 1830s. From 1794, the alternative term 'line of battle ship' was contracted (informally at first) to 'battle ship' or 'battleship'. The sheer number of guns fired broadside meant a ship of the line could wreck any wooden enemy, holing her hull , knocking down masts , wrecking her rigging , and killing her crew. However, the effective range of

16245-583: The famous clash of the USS ; Monitor and the CSS ; Virginia at the Battle of Hampton Roads at least eight navies possessed ironclad ships. Navies experimented with the positioning of guns, in turrets (like the USS Monitor ), central-batteries or barbettes , or with the ram as the principal weapon. As steam technology developed, masts were gradually removed from battleship designs. By

16416-518: The first shots of World War II with the bombardment of the Polish garrison at Westerplatte ; and the final surrender of the Japanese Empire took place aboard a United States Navy battleship, USS  Missouri . Between those two events, it had become clear that aircraft carriers were the new principal ships of the fleet and that battleships now performed a secondary role. Battleships played

16587-457: The following year. The first recorded use of gunpowder weapons in Europe was in 1331 when two mounted German knights attacked Cividale del Friuli with gunpowder weapons of some sort. By 1338 hand cannons were in widespread use in France. English Privy Wardrobe accounts list "ribaldis", a type of cannon, in the 1340s, and siege guns were used by the English at Calais in 1346. Early guns and

16758-401: The guns was as little as a few hundred yards, so the battle tactics of sailing ships depended in part on the wind. Over time, ships of the line gradually became larger and carried more guns, but otherwise remained quite similar. The first major change to the ship of the line concept was the introduction of steam power as an auxiliary propulsion system . Steam power was gradually introduced to

16929-432: The hardened face of Krupp armour via the application of carbonized gases but also retained a much greater fibrous elasticity on the rear of the plate. This increased elasticity greatly reduced the incidence of spalling and cracking under incoming fire, a valuable quality during long engagements. Ballistic testing shows that KCA and Krupp armour were roughly equal in other respects. Developments in face-hardened armour in

17100-423: The harder the armour, the better it might deflect or resist shot. However, the steel being produced at that time proved too brittle to be effective. Iron, being softer, bent, dented and distorted but held together and remained an effective means of protection. Experiments were also carried out with laminated armour , but these did not lead to any improvements and single plates were preferred. Many ships made during

17271-482: The highest grades of the commercial shipbuilding steels were based on this type of steel. Welded Ducol was used in HMS ; Nelson and HMS  Rodney (1927), and may have contributed to initial structural damage when the big guns were fired. A solution was found by using rivets to attach the welded Ducol substructures to the hull rather than the original all-welded construction, allowing for some 'give'. It

17442-406: The ironclad had replaced the unarmoured line-of-battle ship as the most powerful warship afloat. Ironclads were designed for several roles, including as high seas battleships , coastal defence ships, and long-range cruisers . The rapid evolution of warship design in the late 19th century transformed the ironclad from a wooden-hulled vessel which carried sails to supplement its steam engines into

17613-521: The lance and became guns by the late 13th century. Guns such as the hand cannon were being used in the Yuan dynasty by the 1280s. Surviving cannons such as the Heilongjiang hand cannon and the Xanadu Gun have been found dating to the late 13th century and possibly earlier in the early 13th century. In 1287, the Yuan dynasty deployed Jurchen troops with hand cannons to put down a rebellion by

17784-411: The last Royal Navy battleship, the design was so successful he found little support for his plan to switch to a battlecruiser navy. Although there were some problems with the ship (the wing turrets had limited arcs of fire and strained the hull when firing a full broadside, and the top of the thickest armor belt lay below the waterline at full load), the Royal Navy promptly commissioned another six ships to

17955-643: The late 15th century the Ottoman empire used firearms as part of its regular infantry. In the Middle East, the Arabs seem to have used the hand cannon to some degree during the 14th century. Cannons are attested in India starting from 1366. The Joseon kingdom in Korea learned how to produce gunpowder from China by 1372 and started producing cannons by 1377. In Southeast Asia , Đại Việt soldiers used hand cannons at

18126-419: The late nineteenth and early to mid-twentieth centuries revealed that such armour was less effective against glancing oblique impacts. The hardened face layer's brittleness was counterproductive against such impacts. Consequently, alongside face hardened armour such as KCA, homogeneous armour types that combined ductility and tensile strength were developed to protect against glancing impacts. Homogeneous armour

18297-489: The length of guns, and the effective range of engagement. This meant that plunging fire became a serious concern, and lead to the strengthening of deck armor. Belt armor also became much thicker, surpassing 300 mm (12 in) on the largest battleships. One of the most heavily armored ships of all time, the Yamato -class battleship , had main belt of armour up to 410 millimetres (16.1 in) thick. The development of

18468-558: The long duration of its design, which was longer, lighter, more efficient, and more accurate compared to its predecessors 30 years prior. The design persisted for nearly 300 years and cannons of the 1480s show little variation from as well as surprising similarity with cannons three centuries later in the 1750s. This 300-year period during which the classic gun dominated gives it its moniker. The classic gun differed from older generations of firearms through an assortment of improvements. Their longer length-to-bore ratio imparted more energy into

18639-558: The material. One well known example of cast-iron armour for land use is the Gruson turret , first tested by the Prussian government in 1868. Armoured ships may have been built as early as 1203, in the far east . In the West, they first become common when France launched the first ocean-going ironclad La Gloire in 1859. The British Navy responded with HMS Warrior in 1860, triggering

18810-421: The men who used them were often associated with the devil and the gunner's craft was considered a black art , a point reinforced by the smell of sulfur on battlefields created from the firing of guns along with the muzzle blast and accompanying flash . Around the late 14th century in Europe, smaller and portable hand-held cannons were developed, creating in effect the first smooth-bore personal firearm. In

18981-435: The metallurgy as then known, suggested ways for improving its production and quality and helped develop more effective shot against ironclad vessels. For instance, two processes were used in constructing iron armour. In the first, hammering, large lumps of iron of scrap or puddled iron were heated to welding temperature and placed under heavy steel hammers. Repeated blows welded these lumps into one solid plate and shaped it to

19152-414: The mid-1870s steel was used as a construction material alongside iron and wood. The French Navy's Redoutable , laid down in 1873 and launched in 1876, was a central battery and barbette warship which became the first battleship in the world to use steel as the principal building material. The term "battleship" was officially adopted by the Royal Navy in the re-classification of 1892. By the 1890s, there

19323-498: The modern Dreadnought battleship appeared and alongside it the battlecruiser ; the former protected by large amounts of armour which could protect it against all but guns of the largest calibre as found on other battleships, the latter carrying same size guns as a battleship but less armour in order to reach higher speeds. The turn of the 20th century saw a development towards battleships , with large guns and copious armour. In previous eras, large caliber guns had been able to fire on

19494-544: The name chong ( 銃 ) with the metal radical jin ( 金 ) for metal-barrel firearms. Chong was used instead of the earlier and more ambiguous term huo tong (fire tube; 火筒 ), which may refer to the tubes of fire lances , proto-cannons, or signal flares. Hand cannons may have been used in the Mongol invasions of Japan . Japanese descriptions of the invasions mention iron and bamboo pao causing "light and fire" and emitting 2–3,000 iron bullets. The Nihon Kokujokushi , written around 1300, mentions huo tong (fire tubes) at

19665-425: The navy in the first half of the 19th century, initially for small craft and later for frigates . The French Navy introduced steam to the line of battle with the 90-gun Napoléon in 1850—the first true steam battleship. Napoléon was armed as a conventional ship-of-the-line, but her steam engines could give her a speed of 12 knots (22 km/h), regardless of the wind. This was a potentially decisive advantage in

19836-464: The non-intervention blockade. On May 29, 1937, two Republican aircraft managed to bomb the German pocket battleship Deutschland outside Ibiza , causing severe damage and loss of life. Admiral Scheer retaliated two days later by bombarding Almería , causing much destruction, and the resulting Deutschland incident meant the end of German and Italian participation in non-intervention. The Schleswig-Holstein —an obsolete pre-dreadnought —fired

20007-423: The order of minutes, and were unwieldy to aim. But the development of powered aiming systems and ammunition hoists increased the rate of fire up to twice a minute, which combined with other developments, made battleships a finally useful force. The increasing calibers and muzzle velocity of guns required increasingly protective armor to stop projectiles. The development of new, more effective gunpowders also increased

20178-743: The organization of the armouring being carried out by naval officers in key ports. Electric armour is a type of armour proposed for the protection of ships and armoured fighting vehicles from shaped charge weapons. Electric armour uses a strong electric field to disrupt the jet of ionized gas produced by a warhead. Gun A gun is a device designed to propel a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns / cannons ), or gas (e.g. light-gas gun ). Solid projectiles may be free-flying (as with bullets and artillery shells ) or tethered (as with Tasers , spearguns and harpoon guns ). A large- caliber gun

20349-630: The projectile, pushing and accelerating it down the length of the tube, imparting sufficient launch velocity to sustain its further travel towards the target once the propelling gas ceases acting upon it after it exits the muzzle . Alternatively, new-concept linear motor weapons may employ an electromagnetic field to achieve acceleration, in which case the barrel may be substituted by guide rails (as in railguns ) or wrapped with magnetic coils (as in coilguns ). The first devices identified as guns or proto-guns appeared in China from around AD 1000. By

20520-452: The proportion of saltpeter in the propellant was increased to maximise its explosive power. To better withstand that explosive power, the paper and bamboo of which fire-lance barrels were originally made came to be replaced by metal. And to take full advantage of that power, the shrapnel came to be replaced by projectiles whose size and shape filled the barrel more closely. Fire lance barrels made of metal appeared by 1276. Earlier in 1259

20691-694: The rate of fire to six times that of muzzle loading weapons. In 1854, Volcanic Repeating Arms produced a rifle with a self-contained cartridge . In 1849, Claude-Étienne Minié invented the Minié ball , the first projectile that could easily slide down a rifled barrel, which made rifles a viable military firearm, ending the smoothbore musket era. Rifles were deployed during the Crimean War with resounding success and proved vastly superior to smoothbore muskets. In 1860, Benjamin Tyler Henry created

20862-449: The required form and dimensions. Hammered iron plate was the armour used in the earliest ironclad vessels, including HMS Warrior . The second method, rolling, involved stacking iron lumps atop one another, heating them to welding temperature and passing them between two iron rollers to become one plate of the required size. Rolled iron was difficult to produce initially, as it required machinery of immense size and great power. However, when

21033-469: The rules, and sank the ship within minutes in a coordinated attack. The stunt made headlines, and Mitchell declared, "No surface vessels can exist wherever air forces acting from land bases are able to attack them." While far from conclusive, Mitchell's test was significant because it put proponents of the battleship against naval aviation on the defensive. Rear Admiral William A. Moffett used public relations against Mitchell to make headway toward expansion of

21204-437: The same broadside, despite having two fewer guns. In 1897, before the revolution in design brought about by HMS  Dreadnought , the Royal Navy had 62 battleships in commission or building, a lead of 26 over France and 50 over Germany. From the 1906 launching of Dreadnought , an arms race with major strategic consequences was prompted. Major naval powers raced to build their own dreadnoughts. Possession of modern battleships

21375-446: The same diameter as the bore produced from one English pound (454g) of lead) or—as in some British ordnance—the weight of the weapon's usual projectile. A gun projectile may be a simple, single-piece item like a bullet, a casing containing a payload like a shotshell or explosive shell, or complex projectile like a sub-caliber projectile and sabot. The propellant may be air, an explosive solid, or an explosive liquid. Some variations like

21546-510: The same protection as 12 in (300 mm) of Harvey armour. By the early twentieth century, Krupp armour was rendered obsolete by the development of Krupp cemented armour (also "Krupp cemented steel", "K.C. armour" or "KCA"), an evolved variant of Krupp armour. The manufacturing process remained largely the same, with slight changes in the alloy composition: in % of total – carbon 0.35, nickel 3.90, chromium 2.00, manganese 0.35, silicon 0.07, phosphorus 0.025, sulfur 0.020. KCA retained

21717-446: The same weapon, and even referred to as an "arquebus musket." A Habsburg commander in the mid-1560s once referred to muskets as "double arquebuses." A shoulder stock was added to the arquebus around 1470 and the matchlock mechanism sometime before 1475. The matchlock arquebus was the first firearm equipped with a trigger mechanism and the first portable shoulder-arms firearm. Before the matchlock, handheld firearms were fired from

21888-444: The ship's hull. The resultant faults caused by electric welding used in the structural portions of the hull resulted in deformation, and the main gun turrets were unable to train properly. They were re-built with riveted construction, and the other two were redesigned. All of the following ships or classes (the list is not complete) used Ducol in structural bulkheads and protective plating: Lengerer differs considerably as to what

22059-528: The ships' propulsion machinery was protected by a 65-millimeter (2.6 in) deck of CNC armour. The Shōkaku s were the first Japanese carriers to incorporate a torpedo belt system. The torpedo bulkhead itself consisted of an outer Ducol plate 18–30 millimeters (0.71–1.18 in) thick that was riveted to a 12-millimeter (0.47 in) plate." In addition, the IJN's '25-ton' type river motor gun boat had an all-welded hull, protected by 4-5mm Ducol steel. The Italian Navy used

22230-421: The shot, enabling the projectile to shoot further. They were also lighter since the barrel walls were thinner, allowing faster dissipation of heat. They no longer needed the help of a wooden plug to load since they offered a tighter fit between projectile and barrel, further increasing the accuracy of firearms – and were deadlier due to developments such as gunpowder corning and iron shot. Several developments in

22401-566: The standard armament of French and American line-of-battle ships in 1841. In the Crimean War , six line-of-battle ships and two frigates of the Russian Black Sea Fleet destroyed seven Turkish frigates and three corvettes with explosive shells at the Battle of Sinop in 1853. Later in the war, French ironclad floating batteries used similar weapons against the defenses at the Battle of Kinburn . Nevertheless, wooden-hulled ships stood up comparatively well to shells, as shown in

22572-486: The steel-built, turreted battleships and cruisers familiar in the 20th century. This change was pushed forward by the development of heavier naval guns (the ironclads of the 1880s carried some of the heaviest guns ever mounted at sea) , more sophisticated steam engines, and advances in metallurgy which made steel shipbuilding possible. The rapid pace of change in the ironclad period meant that many ships were obsolete as soon as they were complete, and that naval tactics were in

22743-471: The strategic position had changed. In Germany , the ambitious Plan Z for naval rearmament was abandoned in favor of a strategy of submarine warfare supplemented by the use of battlecruisers and commerce raiding (in particular by Bismarck -class battleships). In Britain, the most pressing need was for air defenses and convoy escorts to safeguard the civilian population from bombing or starvation, and re-armament construction plans consisted of five ships of

22914-524: The superstructure on war junks during the Song dynasty (960–1279) and that this tradition was carried on in the Korean turtle ships that defended against Japanese invasion of Korea in the 1590s. The use of iron plate armor on the turtle ships has been suggested in various sources from the 19th century onwards but is not attested in contemporary sources. The first ironclad battleship, with iron armour over

23085-526: The superstructure, and they would be more effective against smaller ships such as cruisers . Smaller guns (12-pounders and smaller) were reserved for protecting the battleship against the threat of torpedo attack from destroyers and torpedo boats . The beginning of the pre-dreadnought era coincided with Britain reasserting her naval dominance. For many years previously, Britain had taken naval supremacy for granted. Expensive naval projects were criticized by political leaders of all inclinations. However, in 1888

23256-487: The technical innovations of the ironclad. Turrets, armor plate, and steam engines were all improved over the years, and torpedo tubes were also introduced. A small number of designs, including the American Kearsarge and Virginia classes , experimented with all or part of the 8-inch intermediate battery superimposed over the 12-inch primary. Results were poor: recoil factors and blast effects resulted in

23427-418: The thickest of armor, and thus warships now focus more on anti-missile technology instead of armor. However, most modern warships retain 25 to 50 mm (0.98 to 1.97 in) of partial armor to protect missiles and aircraft from splinters and light weapons fire. Belt armour is the main side armor on a warship. An armoured citadel is an armoured box enclosing the machinery and magazine spaces, formed by

23598-605: The third, Shinano , was later completed as a carrier) and a planned fourth was cancelled. At the outbreak of the Spanish Civil War , the Spanish navy included only two small dreadnought battleships, España and Jaime I . España (originally named Alfonso XIII ), by then in reserve at the northwestern naval base of El Ferrol , fell into Nationalist hands in July 1936. The crew aboard Jaime I remained loyal to

23769-405: The threat posed to dreadnought battleships proved to have been largely a false alarm. HMS Audacious turned out to be the only dreadnought sunk by a submarine in World War I. While battleships were never intended for anti-submarine warfare, there was one instance of a submarine being sunk by a dreadnought battleship. HMS Dreadnought rammed and sank the German submarine U-29 on March 18, 1915, off

23940-435: The tip. Near the rear, there is a combustion chamber or room, which refers to the bulging part near the rear of the gun, where the gunpowder is placed. The cetbang is mounted on a fixed mount, or as a hand cannon mounted on the end of a pole. There is a tube-like section on the back of the cannon. In the hand cannon-type cetbang, this tube is used as a socket for a pole. The arquebus was a firearm that appeared in Europe and

24111-444: The torpedo and effective naval mines required further considerations for underwater armor, which had not been given much thought in prior eras. The World War era also saw the emergence of the armoured cruiser , which traded some armor in exchange for speed as compared to a battleship. Since World War II, naval armour has been less important, due to the development of guided missiles . Missiles can be highly accurate and penetrate even

24282-426: The use of iron armor plate on warships necessary. In 1859 France launched Gloire , the first ocean-going ironclad warship. She had the profile of a ship of the line, cut to one deck due to weight considerations. Although made of wood and reliant on sail for most journeys, Gloire was fitted with a propeller, and her wooden hull was protected by a layer of thick iron armor. Gloire prompted further innovation from

24453-595: The very latest by 1390 when they employed them in killing Champa king Che Bong Nga. Chinese observer recorded the Javanese use of hand cannon for marriage ceremony in 1413 during Zheng He 's voyage. Hand guns were utilized effectively during the Hussite Wars . Japan knew of gunpowder due to the Mongol invasions during the 13th century, but did not acquire a cannon until a monk took one back to Japan from China in 1510, and guns were not produced until 1543, when

24624-483: The war wore on however, it turned out that whilst submarines did prove to be a very dangerous threat to older pre-dreadnought battleships, as shown by examples such as the sinking of Mesûdiye , which was caught in the Dardanelles by a British submarine and HMS  Majestic and HMS  Triumph were torpedoed by U-21 as well as HMS  Formidable , HMS  Cornwallis , HMS  Britannia etc.,

24795-451: The war, and it was the last major battle in naval history fought primarily by battleships. The Naval Treaties of the 1920s and 1930s limited the number of battleships, though technical innovation in battleship design continued. Both the Allied and Axis powers built battleships during World War II, though the increasing importance of the aircraft carrier meant that the battleship played

24966-623: The weather deck and the bulkheads." HMS  Ark Royal 's fully-enclosed armoured hangar and the armoured flight deck which it supported were constructed of Ducol. Other types of armour used on Navy ships: The Imperial Japanese Navy (IJN) made considerable use of Ducol made under licence by Japan Steel Works in Muroran , Hokkaidō , Japan : the company was set up with investment from Vickers , Armstrong Whitworth and Mitsui . The Mogami -class cruisers were originally designed with all-welded Ducol bulkheads which were then welded to

25137-640: The weights of ships. Designs like the projected British N3-class battleship, the first American South Dakota class , and the Japanese Kii class —all of which continued the trend to larger ships with bigger guns and thicker armor—never got off the drawing board. Those designs which were commissioned during this period were referred to as treaty battleships . As early as 1914, the British Admiral Percy Scott predicted that battleships would soon be made irrelevant by aircraft . By

25308-467: The world obsolete, testified in front of Congress that "1,000 bombardment airplanes can be built and operated for about the price of one battleship" and that a squadron of these bombers could sink a battleship, making for more efficient use of government funds. This infuriated the U.S. Navy, but Mitchell was nevertheless allowed to conduct a careful series of bombing tests alongside Navy and Marine bombers. In 1921, he bombed and sank numerous ships, including

25479-494: Was Sir William Fairbairn , a noted civil and structural engineer who had also built over 80 iron vessels before retiring from shipbuilding. Other members included metallurgist John Percy , civil engineer William Pole and representatives of the Royal Engineers , Royal Artillery and Royal Navy . This committee worked four years, between 1861 and 1865, during which time it formulated the best performing armour with

25650-415: Was a type of armour used on warships and, to a limited degree, fortifications. The use of iron gave rise to the term ironclad as a reference to a ship 'clad' in iron. The earliest material available in sufficient quantities for armouring ships was iron , wrought or cast. While cast iron has never been used for naval armour, it did find a use in land fortifications , presumable due to the lower cost of

25821-462: Was an increasing similarity between battleship designs, and the type that later became known as the 'pre-dreadnought battleship' emerged. These were heavily armored ships, mounting a mixed battery of guns in turrets, and without sails. The typical first-class battleship of the pre-dreadnought era displaced 15,000 to 17,000  tons , had a speed of 16 knots (30 km/h), and an armament of four 12-inch (305 mm) guns in two turrets fore and aft with

25992-414: Was depicted in a silk painting dated to the mid-10th century, but textual evidence of its use does not appear until 1132, describing the siege of De'an . It consisted of a bamboo tube of gunpowder tied to a spear or other polearm. By the late 1100s, ingredients such as pieces of shrapnel like porcelain shards or small iron pellets were added to the tube so that they would be blown out with the gunpowder. It

26163-520: Was described as a possible candidate for "the first ironclad" by authors in the late 19th and early 20th century. The Finis Belli was a stationary floating fighting platform that was built by the Dutch during the Siege of Antwerp in 1585. It was supposedly equipped with iron plates but never actually saw action. According to science historian Joseph Needham , thin metal sheets were used as protection on

26334-399: Was effective because the very hard particles would deflect bullets which would then lodge between the plastic armour and the steel backing plate. Plastic armour could be applied by pouring it into a cavity formed by the steel backing plate and a temporary wooden form. Production of the armour was by road construction firms and was carried out in a similar way to the production of road coverings,

26505-410: Was effective beyond visual range and effective in complete darkness or adverse weather, was introduced to supplement optical fire control. Even when war threatened again in the late 1930s, battleship construction did not regain the level of importance it had held in the years before World War I. The "building holiday" imposed by the naval treaties meant the capacity of dockyards worldwide had shrunk, and

26676-524: Was his brainchild, the battlecruiser : lightly armored but heavily armed with eight 12-inch guns and propelled to 25 knots (46 km/h) by steam turbines . It was to prove this revolutionary technology that Dreadnought was designed in January 1905, laid down in October 1905 and sped to completion by 1906. She carried ten 12-inch guns, had an 11-inch armor belt, and was the first large ship powered by turbines. She mounted her guns in five turrets; three on

26847-467: Was incorporated into the English language as "blunderbuss". Artillerymen were often referred to as "gonners" and "artillers" "Hand gun" was first used in 1373 in reference to the handle of guns. According to the Merriam-Webster dictionary, a gun could mean "a piece of ordnance usually with high muzzle velocity and comparatively flat trajectory," " a portable firearm," or "a device that throws

27018-572: Was invented by the American engineer Hayward Augustus Harvey . The Harvey United Steel Company was a steel cartel whose chairman was Albert Vickers . The year 1894 would see the ten main producers of armor plate, including Vickers , Armstrong , Krupp , Schneider , Carnegie and Bethlehem Steel , form the Harvey Syndicate. Krupp armour was a type of steel armour used in the construction of capital ships starting shortly before

27189-441: Was later adopted by other navies after the First World War , beginning with the Royal Navy in its Nelson class in combination with reducing the amount of ship that needed armouring by mounting all the main armament forward. The development of aircraft carriers necessitated new forms of protection. An armoured flight deck is an aircraft carrier flight deck that incorporates substantial armour in its design. Iron armour

27360-406: Was made of Ducol, perhaps because of the extensive refit in 1934–36? "The lower strake of the armour was backed by 50 millimeters (2.0 in) of Ducol steel. The magazines were protected by 165 millimeters (6.5 in) of New Vickers Non-Cemented (NVNC) armour, sloped at an inclination up to 25° and tapered to thicknesses of 55–75 millimeters (2.2–3.0 in). The flight and both hangar decks were unprotected and

27531-422: Was not only seen as vital to naval power, but also, as with nuclear weapons after World War II , represented a nation's standing in the world. Germany , France , Japan , Italy , Austria , and the United States all began dreadnought programmes; while the Ottoman Empire , Argentina , Russia , Brazil , and Chile commissioned dreadnoughts to be built in British and American yards. By virtue of geography,

27702-446: Was only one of a number of technological advances which revolutionized warship design in the 19th century. The ship of the line was overtaken by the ironclad : powered by steam, protected by metal armor, and armed with guns firing high-explosive shells . Guns that fired explosive or incendiary shells were a major threat to wooden ships, and these weapons quickly became widespread after the introduction of 8-inch shell guns as part of

27873-524: Was part of the armouring scheme in some warships between the 1920s and 1940s. It consisted of a series of lightly armoured compartments, extending laterally along a narrow belt that intersected the ship's waterline. In theory this belt would absorb the explosions from torpedoes, or any naval artillery shells that struck below the waterline, and thus minimize internal damage to the ship itself. Torpedo belts are also known as Side Protection Systems or SPS, or Torpedo Defense System or TDS. Developed for use during

28044-670: Was previously known as gunpowder, was relegated to hobbyist usage. In 1861, Richard Jordan Gatling invented the Gatling gun , the first successful machine gun, capable of firing 200 gunpowder cartridges in a minute. It was fielded by the Union forces during the American Civil War in the 1860s. In 1884, Hiram Maxim invented the Maxim gun , the first single-barreled machine gun. The world's first submachine gun (a fully automatic firearm which fires pistol cartridges) able to be maneuvered by

28215-583: Was probably somewhat similar to the British Ducol ("D" or "Dl") Steel used for light armour and torpedo bulkheads in WWII. Plastic armour (also known as plastic protection) was a type of vehicle armour originally developed for merchant ships by Edward Terrell of the British Admiralty in 1940. It consisted of small, evenly sized aggregate in a matrix of bitumen, similar to asphalt concrete. It

28386-405: Was relatively short ranged and had a range of roughly 3 meters by the early 13th century. This fire lance is considered by some historians to be a "proto-gun" because its projectiles did not occlude the barrel. There was also another "proto-gun" called the eruptor, according to Joseph Needham, which did not have a lance but still did not shoot projectiles which occluded the barrel. In due course,

28557-517: Was restricted to skirmishes. In the Baltic Sea , action was largely limited to the raiding of convoys, and the laying of defensive minefields; the only significant clash of battleship squadrons there was the Battle of Moon Sound at which one Russian pre-dreadnought was lost. The Adriatic was in a sense the mirror of the North Sea: the Austro-Hungarian dreadnought fleet remained bottled up by

28728-423: Was sunk by destroyers during the night phase of the Battle of Jutland. The German High Seas Fleet, for their part, were determined not to engage the British without the assistance of submarines; and since the submarines were needed more for raiding commercial traffic, the fleet stayed in port for much of the war. For many years, Germany simply had no battleships. The Armistice with Germany required that most of

28899-498: Was typically applied as a casting in situ in a layer about two inches (51 mm) thick on to existing ship structures made from one-quarter-inch-thick (6.4 mm) mild steel or formed in equally thick sections on a one-half-inch-thick (13 mm) steel plate for mounting as gun shields and the like. Plastic armour replaced the use of concrete slabs which, although expected to provide protection, were prone to cracking and breaking up when struck by armour-piercing bullets. Plastic armour

29070-412: Was typically used for deck armour, which is subject to more high-obliquity impacts and, on some warships such as Yamato class and Iowa class battleships, for lower belt armour below the waterline to protect against shells that land short and dive underwater. Ducol or "D"-steel is the name of a number of high-strength low-alloy steels of varying composition, first developed from the early 1920s by

29241-587: Was used in British anti-torpedo-system design practice in its last battleships. The internal hull and torpedo bulkheads and internal decks were made of Ducol or "D"-class steel, an extra-strong form of HTS . According to Nathan Okun, the King George V-class battleships had the simplest armour arrangement of all post-WWI capital ships. "Most of the load-bearing portions of the ship were constructed of British Ducol ("D" or "D.1") extra-high-strength silicon-manganese high-tensile construction steel, including
