119-654: The Kriegsmarine ( German pronunciation: [ˈkʁiːksmaˌʁiːnə] , lit.   ' War Navy ' ) was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic . The Kriegsmarine was one of three official branches , along with the Heer and

238-551: A limited and asymmetric nature. Naval warfare developed when humans first fought from water-borne vessels. Before the introduction of the cannon and ships with enough capacity to carry them, navy warfare primarily involved ramming and boarding actions. In the time of ancient Greece and the Roman Empire , naval warfare centered on long, narrow vessels powered by banks of oarsmen (such as triremes and quinqueremes ) designed to ram and sink enemy vessels or come alongside

357-489: A sister ship of Bismarck , was almost put out of action by miniature submarines known as X-Craft . The X-Craft severely damaged her and kept her in port for some months. A major paradigm shift in naval warfare occurred with the introduction of the aircraft carrier . First at Taranto in 1940 and then at Pearl Harbor in 1941, the carrier demonstrated its ability to strike decisively at enemy ships out of sight and range of surface vessels. The Battle of Leyte Gulf (1944)

476-822: A catastrophe for the Russian military in general and the Russian Navy in particular. Although neither party lacked courage, the Russians were defeated by the Japanese in the Battle of Port Arthur, which was the first time in warfare that mines were used for offensive purposes. The warships of the Baltic Fleet sent to the Far East were lost in the Battle of Tsushima. A further step change in naval firepower occurred when

595-581: A dozen destroyers were operational) were divided among the victors by the Tripartite Naval Commission . The US used the heavy cruiser Prinz Eugen in nuclear testing at Bikini Atoll in 1946 as a target ship for the Operation Crossroads . Some (like the unfinished aircraft carrier Graf Zeppelin ) were used for target practice with conventional weapons, while others (mostly destroyers and torpedo boats) were put into

714-404: A group, which may be a small squadron of comparable ships, or a larger naval fleet of various specialized ships. The commander of a fleet travels in the flagship , which is usually the most powerful vessel in the group. Before radio was invented, commands from the flagship were communicated by means of flags. At night signal lamps could be used for a similar purpose. Later these were replaced by

833-661: A heavy ship suitable for offensive warfare on the high seas while still abiding by the letter of the treaty. When the Nazis came to power in 1933, Hitler soon began to more brazenly ignore many of the Treaty restrictions and accelerated German naval rearmament. The Anglo-German Naval Agreement of 18 June 1935 allowed Germany to build a navy equivalent to 35% of the British surface ship tonnage and 45% of British submarine tonnage; battleships were to be limited to 35,000 tons. That same year

952-437: A large number of cannon made oar-based propulsion impossible, and ships came to rely primarily on sails . Warships were designed to carry increasing numbers of cannon and naval tactics evolved to bring a ship's firepower to bear in a broadside , with ships-of-the-line arranged in a line of battle . The development of large capacity, sail-powered ships carrying cannon led to a rapid expansion of European navies, especially

1071-554: A legitimate military target, resulting in the deaths of 117 civilians. Germany did not admit responsibility for the incident until after the war. Lemp was killed in action in 1941. U-247 was alleged to have shot at sunken ship survivors, but as the vessel was lost at sea with its crew, there was no investigation. In 1945, U-boat Commander Heinz-Wilhelm Eck of U-852 was tried along with four of his crewmen for shooting at survivors. All were found guilty, with three of them, including Eck, being executed. In 1946, Hellmuth von Ruckteschell

1190-591: A major naval power in the mid-17th century in the first Anglo-Dutch war with a technical victory. Successive decisive Dutch victories in the second and third Anglo-Dutch Wars confirmed the Dutch mastery of the seas during the Dutch Golden Age , financed by the expansion of the Dutch Empire . The French Navy won some important victories near the end of the 17th century but a focus upon land forces led to

1309-484: A major re-armament of the navy (Plan Z) was planned, and initially begun, the start of the war in 1939 meant that the vast amounts of material required for the project were diverted to other areas. The sheer disparity in size when compared to the other European powers navies prompted Raeder to write of his own navy once the war began "The surface forces can do no more than show that they know how to die gallantly." A number of captured ships from occupied countries were added to

1428-682: A military fleet, although the term " merchant navy " for a commercial fleet still incorporates the non-military word sense . This overlap in word senses between commercial and military fleets grew out of the inherently dual-use nature of fleets; centuries ago, nationality was a trait that unified a fleet across both civilian and military uses. Although nationality of commercial vessels has little importance in peacetime trade other than for tax avoidance , it can have greater meaning during wartime, when supply chains become matters of patriotic attack and defense, and when in some cases private vessels are even temporarily converted to military vessels. The latter

1547-806: A navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes , deter or confront piracy , ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles . Naval operations can be broadly divided between riverine and littoral applications ( brown-water navy ), open-ocean applications ( blue-water navy ), and something in between ( green-water navy ), although these distinctions are more about strategic scope than tactical or operational division. First attested in English in

1666-543: A new navy was established and was referred to as the Bundesmarine (Federal Navy). Some Kriegsmarine commanders like Erich Topp and Otto Kretschmer went on to serve in the Bundesmarine . In East Germany the Volksmarine (People's Navy) was established in 1956. With the reunification of Germany in 1990, it was decided to use the name Deutsche Marine ( German Navy ). By the start of World War II, much of

1785-821: A result, the submarines had much success for few losses (this period was dubbed the First Happy Time by the Germans). Italy entered the war in June 1940, and the Battle of the Mediterranean began: from September 1941 to May 1944 some 62 German submarines were transferred there, sneaking past the British naval base at Gibraltar . The Mediterranean submarines sank 24 major Allied warships (including 12 destroyers, 4 cruisers, 2 aircraft carriers, and 1 battleship) and 94 merchant ships (449,206 tons of shipping). None of

1904-458: A single ship or aspect of a ship. However, commodores can also be temporary or honorary positions. For example, during World War II, a Navy captain was assigned duty as a convoy commodore, which meant that he was still a captain, but in charge of all the merchant vessels in the convoy. The most senior rank employed by a navy will tend to vary depending on the size of a navy and whether it is wartime or peacetime, for example, few people have ever held

2023-691: A small number of targets in the area throughout the conflict. (By comparison the Italian Regia Marina operated 58 submarines in the area as part of the Sottomarini Legionari .) The Kriegsmarine saw as her main tasks the controlling of the Baltic Sea and winning a war against France in connection with the German army, because France was seen as the most likely enemy in the event of war. But in 1938 Hitler wanted to have

2142-570: A step in the formation of a modern German fleet. The building of the Deutschland caused consternation among the French and the British as they had expected that the restrictions of the Treaty of Versailles would limit the replacement of the pre-dreadnought battleships to coastal defence ships , suitable only for defensive warfare. By using innovative construction techniques, the Germans had built

2261-517: A team of skilled and experienced German and Dutch engineers that were led by technical director Hans Techel, the former director of U-boat design at Germaniawerft. In 1925, after resolving their legal technicalities with the Dutch government, IvS finally opened its office in The Hague and the eleven-man staff that were leading the firm from the office in Kiel moved to the Dutch office. This office at

2380-781: A telegram to the German Navy's Baltic Command in Kiel , which stated that he wanted 100 SS and fifty Schutzpolizei (protective police) men sent to Liepāja for "quick implementation Jewish problem". Kawelmacher hoped to accelerate the killings, complaining: "Here about 8,000 Jews... with present SS-personnel, this would take one year, which is untenable for [the] pacification of Liepāja." Kawelmacher telegram on 27 July 1941 read: "Jewish problem Libau largely solved by execution of about 1,100 male Jews by Riga SS commando on 24 and 25.7." In September 1939, U-boat commander Fritz-Julius Lemp of U-30 sank SS Athenia (1922) after mistaking it for

2499-753: A variety of other roles. NV Ingenieurskantoor voor Scheepsbouw The company was a joint venture by the German shipyards AG Vulcan Stettin (located in Stettin and Hamburg ), the Krupp -owned Germaniawerft in Kiel , and AG Weser in Bremen . Design work was carried out at the facilities of these companies in Germany. At the time of IvS, the Germans were bound by the Treaty of Versailles, signed in 1919. This treaty, among other terms, demanded that all German U-boats be destroyed or given to other nations. Thus

2618-410: A way that IvS employees (many of whom were former Kaiserliche Marine and Reichsmarine personnel) were involved with crew training and selection, and were also allowed to take part in submarine service trials. The Germans - who were, at the time, tightly restricted from using submarines themselves - thus gained first-hand knowledge of how their prototypes worked in practice. The company also designed

2737-1233: Is an integral part of the navy but there are variations such as the French Troupes de marine , which is actually part of the French Army . The United States Marine Corps is a separate armed service within the United States Department of the Navy, with its own leadership structure. Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. In World War I, several navies used floatplanes and flying boats – mainly for scouting . By World War II, aircraft carriers could carry bomber aircraft capable of attacking naval and land targets, as well as fighter aircraft for defence. Since World War II helicopters have been embarked on smaller ships in roles such as anti-submarine warfare and transport. Some navies have also operated land-based aircraft in roles such as maritime patrol and training . Naval aviation forces primarily perform naval roles at sea. However, they are also used in

2856-501: Is argument, this has been noted. The main combat ships of the Kriegsmarine (excluding U-boats): Construction of Graf Zeppelin was started in 1936 and construction of an unnamed sister ship was started two years later in 1938, but neither ship was completed. In 1942 conversion of three German passenger ships ( Europa , Potsdam , Gneisenau ) and two unfinished cruisers, the captured French light cruiser De Grasse and

2975-482: Is currently building one aircraft carrier, INS  Vikrant , and considering another. France is also looking at a new carrier , probably using a CATOBAR system and possibly based on the British Queen Elizabeth design. A navy typically operates from one or more naval bases . The base is a port that is specialized in naval operations, and often includes housing, a munitions depot , docks for

3094-709: Is that boats are capable of being carried by ships. (Submarines by this rule are ships rather than boats, but are customarily referred to as boats reflecting their previous smaller size.) Navies use many types of boat, ranging from 9-foot (2.7 m) dinghies to 135-foot (41 m) landing craft. They are powered by either diesel engines, out-board gasoline engines, or waterjets. Most boats are built of aluminum, fiberglass, or steel. Rigid-hulled inflatable boats are also used. Patrol boats are used for patrols of coastal areas, lakes and large rivers. Landing craft are designed to carry troops, vehicles, or cargo from ship to shore under combat conditions, to unload, to withdraw from

3213-717: The Luftwaffe , of the Wehrmacht , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles , the Kriegsmarine grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines . Kriegsmarine ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under

3332-541: The Kriegsmarine (as for all branches of the armed forces during the period of absolute Nazi power) was Adolf Hitler , who exercised his authority through the Oberkommando der Marine ('High Command of the Navy'). Among the Kriegsmarine 's most significant ships were its U-boats, most of which were constructed after Plan Z was abandoned at the beginning of World War II. Wolfpacks were rapidly assembled groups of submarines which attacked British convoys during

3451-907: The Birinci İnönü class . They were followed by the Submarino E-1 built in 1930 by the Echevarrieta y Larrinaga shipyard in Cádiz , Spain , initially for the Spanish Navy , but mainly as a prototype of the German Type I submarine and Type VII submarine . However, the Spanish lost interest in the E-1 , and it was also sold to Turkey in 1935 as the TCG Gür . In 1936 it was reported in

3570-789: The Finnish Navy Vesikko ), was the prototype of the German Type II submarine, while three larger Vetehinen -class submarines served as the prototypes for the Type VII. A fifth IvS design was the small submarine Saukko , built in Helsinki by the Sandvikens Skeppsdocka och Mekaniska Verkstad shipyard, and originally planned to be deployed in Lake Ladoga . The contracts were worded in such

3689-582: The Finnish Navy coastal defense ships Väinämöinen and Ilmarinen in the late 1920s. Both ships were also built by Crichton-Vulcan Oy, entering service in 1932 and 1934, respectively. The IvS was also involved in designing plans for a Royal Netherlands Navy project to build battlecruisers . Battlecruisers were deemed by some to be essential for the defense of the Dutch East Indies against possible Japanese expansion, especially as

3808-500: The G7e torpedo was developed. Even before the Nazi seizure of power on 30 January 1933 the German government decided on 15 November 1932 to launch a prohibited naval re-armament program that included U-boats, airplanes, and an aircraft carrier. The launching of the first pocket battleship , Deutschland in 1931 (as a replacement for the old pre-dreadnought battleship Preussen ) was

3927-646: The German Mine Sweeping Administration (GMSA), which consisted of 27,000 members of the former Kriegsmarine and 300 vessels. The destroyers and the Soviet share light cruiser Nürnberg were all retired by the end of the 1950s, but five escort destroyers were returned from the French to the new West German Navy in the 1950s and three 1945 scuttled type XXI and XXIII U-boats were raised by West Germany and integrated into their new navy. In 1956, with West Germany's accession to NATO ,

4046-697: The Gneisenau was heavily damaged by a British air raid in 1942 and the Scharnhorst was sunk in the Battle of the North Cape in late 1943. The second pair were the 15-inch gun Bismarck class , consisting of the Bismarck and Tirpitz . The Bismarck was sunk on her first sortie into the Atlantic in 1941 ( Operation Rheinübung ) although she did sink the battlecruiser Hood and severely damaged

4165-514: The Kriegsmarine in Norway were seldom involved in these attacks, because of the inferiority of German radar technology, and because Hitler and the leadership of the Kriegsmarine feared losses of these precious ships. The most effective of these attacks was the near destruction of Convoy PQ 17 in July 1942. Later in the war German attacks on these convoys were mostly reduced to U-boat activities and

4284-414: The Kriegsmarine were modern ships: fast, well-armed, and well-armoured. This had been achieved by concealment but also by deliberately flouting World War I peace terms and those of various naval treaties. However, the war started with the German Navy still at a distinct disadvantage in terms of sheer size with what were expected to be its primary adversaries – the navies of France and Great Britain. Although

4403-593: The Reichsmarine was left without a submarine capability, and IvS was created to work around these restrictions. The work of the company was a major factor in the foundation of the Kriegsmarine of World War II . NV Ingenieurskantoor voor Scheepsbouw (IvS) was founded on 21 July 1922 and initially was led from the Germaniawerft in Kiel , Germany. During this time the company gradually built up

4522-552: The Reichsmarine was renamed as the Kriegsmarine . In April 1939, as tensions escalated between the United Kingdom and Germany over Poland , Hitler unilaterally rescinded the restrictions of the Anglo-German Naval Agreement. The building-up of the German fleet in the time period of 1935–1939 was slowed by problems with marshaling enough manpower and material for ship building. This was because of

4641-528: The Spanish and Portuguese navies that dominated in the 16th and early 17th centuries, and helped propel the age of exploration and colonialism . The repulsion of the Spanish Armada (1588) by the English fleet revolutionized naval warfare by the success of a guns-only strategy and caused a major overhaul of the Spanish Navy , partly along English lines, which resulted in even greater dominance by

4760-414: The evacuation of East Prussia and Danzig from January to May 1945. It was during this activity that the catastrophic sinking of several large passenger ships occurred: Wilhelm Gustloff and Goya were sunk by Soviet submarines, while Cap Arcona was sunk by British bombers, each sinking claiming thousands of civilian lives. The Kriegsmarine also provided important assistance in the evacuation of

4879-537: The oiler , minesweeper , patrol boat , hydrographic and oceanographic survey ship and tender . During the age of sail , the ship categories were divided into the ship of the line , frigate, and sloop-of-war . Naval ship names are typically prefixed by an abbreviation indicating the national navy in which they serve. For a list of the prefixes used with ship names ( HMS , USS , LÉ , etc.) see ship prefix . Today's warships are significantly faster than in years past, thanks to much improved propulsion systems. Also,

4998-530: The Atlantic coast at Brest were evacuated back to German ports for deployment to Norway. The ships had been repeatedly damaged by air attacks by the RAF , the supply ships to support Atlantic sorties had been destroyed by the Royal Navy, and Hitler now felt that Norway was the "zone of destiny" for these ships. The two battleships Scharnhorst and Gneisenau and the heavy cruiser Prinz Eugen passed through

5117-675: The Battle of the Barents Sea, which convinced Hitler that large warships were useless. All engineering of the aircraft carriers like catapults, arresting gears and so on were tested and developed at the Erprobungsstelle See Travemünde (Experimental Agency Sea in Travemünde) including the airplanes for the aircraft carriers, the Fieseler Fi 167 ship-borne biplane torpedo and reconnaissance bomber and

5236-764: The English Channel ( Channel Dash ) on their way to Norway despite British efforts to stop them. Not since the Spanish Armada in 1588 had any warships in wartime done this. It was a tactical victory for the Kriegsmarine and a blow to British morale, but the withdrawal removed the possibility of attacking allied convoys in the Atlantic with heavy surface ships. With the German attack on the Soviet Union in June 1941 Britain started to send Arctic convoys with military goods around Norway to support their new ally. In 1942 German forces began heavily attacking these convoys, mostly with bombers and U-boats. The big ships of

5355-648: The French Navy's relative neglect, which allowed the Royal Navy to emerge with an ever-growing advantage in size and quality, especially in tactics and experience, from 1695. As a response to growing naval influence of the navies of Portuguese, the warrior king of the Marathas, Shivaji laid the foundation of the Maratha navy in 1654. Throughout the 18th century the Royal Navy gradually gained ascendancy over

5474-401: The French Navy, with victories in the War of Spanish Succession (1701–1714), inconclusive battles in the War of Austrian Succession (1740–1748), victories in the Seven Years' War (1754–1763), a partial reversal during the American War of Independence (1775–1783), and consolidation into uncontested supremacy during the 19th century from the Battle of Trafalgar in 1805. These conflicts saw

5593-412: The German Navy was heavily involved in the invasion of Norway , where it suffered significant losses, which included the heavy cruiser Blücher sunk by artillery and torpedoes from Norwegian shore batteries at the Oscarsborg Fortress in the Oslofjord . Ten destroyers were lost in the Battles of Narvik (half of German destroyer strength at the time), and two light cruisers, the Königsberg which

5712-426: The German fleet as the war progressed. Though six major units of the Kriegsmarine were sunk during the war (both Bismarck -class battleships and both Scharnhorst -class battleships, as well as two heavy cruisers), there were still many ships afloat (including four heavy cruisers and four light cruisers) as late as March 1945. Some ship types do not fit clearly into the commonly used ship classifications. Where there

5831-465: The German fleet at the beginning of the war was not even 20% of Plan Z. On 1 September 1939, the navy still had a total personnel strength of only 78,000, and it was not at all ready for a major role in the war. Because of the long time it would take to get the Plan Z fleet ready for action and shortage in workers and material in wartime, Plan Z was essentially shelved in September 1939 and the resources allocated for its realisation were largely redirected to

5950-399: The German heavy cruiser Seydlitz , to auxiliary carriers was begun. In November 1942 the conversion of the passenger ships was stopped because these ships were now seen as too slow for operations with the fleet. But conversion of one of these ships, the Potsdam , to a training carrier was begun instead. In February 1943 all the work on carriers was halted because of the German failure during

6069-433: The Germans invaded the Netherlands . In 1933, the Reichsmarine established a training school in Kiel for U-boat crews, called the Unterseebootsabwehrschule ("Submarine Defence School"). This program provided for a small fleet of eight 500-tonne submarines, later doubled to sixteen. Later plans for an actual U-boat fleet included designs for submarines referred to as "Experimental Motor Boats". Deutsche Werke in Kiel

6188-426: The Mediterranean submarines made it back to their home bases, as they were all either sunk in battle or scuttled by their crews at the end of the war. In 1941, one of the four modern German battleships, Bismarck sank HMS  Hood while breaking out into the Atlantic for commerce raiding. The Bismarck was in turn hunted down by much superior British forces after being crippled by an air-launched torpedo. She

6307-449: The Netherlands lacked any large surface ships. The designs were heavily influenced by the German Scharnhorst class and the final design was similar to the IvS design, because the Germans were expected to at least furnish the gun turrets for these ships, as constructing them was beyond Dutch capabilities. In the end, political disagreements delayed the decision-making process and none of the projected ships were laid down, as on May 10, 1940

6426-528: The Republican attack were 31 dead and 110 wounded, 71 seriously, mostly burn victims. In retaliation the Admiral Scheer shelled Almeria on 31 May killing 19–20 civilians, wounding 50 and destroying 35 buildings. Following further attacks by Republican submarines against the Leipzig off the port of Oran between 15 and 18 June 1937 Germany withdrew from the Non-Intervention Patrol. U-boats also participated in covert action against Republican shipping as part of Operation Ursula . At least eight U-boats engaged

6545-435: The Spanish. From the beginning of the 17th century the Dutch cannibalized the Portuguese Empire in the East and, with the immense wealth gained, challenged Spanish hegemony at sea. From the 1620s, Dutch raiders seriously troubled Spanish shipping and, after a number of battles that went both ways, the Dutch Navy finally broke the long dominance of the Spanish Navy in the Battle of the Downs (1639). England emerged as

6664-485: The U.S. Navy lifted the ban in April 2010. The major reasons historically cited by the U.S. Navy were the extended duty tours and close conditions which afford almost no privacy. The United Kingdom's Royal Navy has had similar restrictions. Australia, Canada, Norway, and Spain previously opened submarine service to women sailors. A navy will typically have two sets of ranks, one for enlisted personnel and one for officers . Typical ranks for commissioned officers include

6783-423: The United Kingdom ( Operation Sea Lion ) in the summer of 1940. There were serious doubts that the invasion sea routes could have been protected against British naval interference. The Fall of France and the conquest of Norway gave German submarines greatly improved access to British shipping routes in the Atlantic . At first, British convoys lacked escorts that were adequate either in numbers or equipment and, as

6902-503: The United Kingdom launched HMS  Dreadnought in 1906, but naval tactics still emphasized the line of battle. The first practical military submarines were developed in the late 19th century and by the end of World War I had proven to be a powerful arm of naval warfare. During World War II , Nazi Germany 's submarine fleet of U-boats almost starved the United Kingdom into submission and inflicted tremendous losses on U.S. coastal shipping . The German battleship  Tirpitz ,

7021-446: The United States in December 1941 led to another phase of the Battle of the Atlantic. In Operation Drumbeat and subsequent operations until August 1942, a large number of Allied merchant ships were sunk by submarines off the US coast as the Americans had not prepared for submarine warfare, despite clear warnings (this was the so-called Second Happy Time for the German Navy). The situation became so serious that military leaders feared for

7140-403: The adoption of convoy escorts , especially in the Atlantic, greatly reduced the effectiveness of surface commerce raiders against convoys. Following the end of World War II in 1945, the Kriegsmarine 's remaining ships were divided up among the Allied powers and were used for various purposes including minesweeping . Some were loaded with superfluous chemical weapons and scuttled. Under

7259-540: The battleship Tirpitz , was stationed in Norway as a threat to Allied shipping and also as a defence against a potential Allied invasion. When she was sunk, after several attempts, by British bombers in November 1944 ( Operation Catechism ), several British capital ships could be moved to the Far East. From late 1944 until the end of the war, the surviving surface fleet of the Kriegsmarine (heavy cruisers: Admiral Scheer , Lützow , Admiral Hipper , Prinz Eugen , light cruisers: Nürnberg , Köln , Emden )

7378-520: The battleship Prince of Wales , while the Tirpitz was based in Norwegian ports during most of the war as a fleet in being, tying up Allied naval forces, and subject to a number of attacks by British aircraft and submarines. More battleships were planned (the H-class), but construction was abandoned in September 1939. The World War I-era pre-dreadnought battleships Schlesien and Schleswig-Holstein were used mainly as training ships, although they also participated in several military operations, with

7497-998: The beach, and to return to the ship. They are rugged, with powerful engines, and usually armed. There are many types in today's navies including hovercraft . They will typically have a power-operated bow ramp, a cargo well and after structures that house engine rooms, pilot houses, and stowage compartments. These boats are sometimes carried by larger ships. Special operations craft are high-speed craft used for insertion and extraction of special forces personnel and some may be transportable (and deployed) by air. Boats used in non-combat roles include lifeboats, mail boats, line handling boats, buoy boats, aircraft rescue boats, torpedo retrievers, explosive ordnance disposal craft, utility boats, dive boats, targets, and work boats. Boats are also used for survey work, tending divers, and minesweeping operations. Boats for carrying cargo and personnel are sometimes known as launches, gigs, barges or shore party boats. Naval forces are typically arranged into units based on

7616-417: The brokering of the International Non-Intervention Patrol to enforce an international arms embargo, the Kriegsmarine was allotted the patrol area between Cabo de Gata (Almeria) and Cabo de Oropesa . Numerous vessels served as part of these duties including Admiral Graf Spee . On 29 May 1937 the Deutschland was attacked off Ibiza by two bombers from the Republican Air Force . Total casualties from

7735-450: The coastal periphery and along inland waterways, where larger ocean-going naval vessels can not readily enter. Regional powers may maintain a " green water navy " as a means of localized force projection. Blue water fleets may require specialized vessels, such as minesweepers , when operating in the littoral regions along the coast. A basic tradition is that all ships commissioned in a navy are referred to as ships rather than vessels, with

7854-401: The construction of U-boats, which would be ready for war against the United Kingdom more quickly. The Kriegsmarine took part in the Battle of Westerplatte and the Battle of the Danzig Bay during the invasion of Poland . In 1939, major events for the Kriegsmarine were the sinking of the British aircraft carrier HMS  Courageous and the British battleship HMS  Royal Oak and

7973-459: The corner of the Wagenstraat and Gedempte burgwal would be used by IvS till its dissolution in 1945. At first IvS used the old UB III and UC III boats of the Imperial German Navy as starting point for their new submarine designs. IvS first designed two submarines based on the World War I UB III submarine of the Kaiserliche Marine . Both were built by the Fijenoord shipyard in Rotterdam in 1927 and sold to Turkey , where they formed

8092-518: The development and deployment of midget submarines like the Molch and Seehund . In the last stage of the war, the Kriegsmarine also organised a number of divisions of infantry from its personnel. Between 1943 and 1945, a group of U-boats known as the Monsun Boats ( Monsun Gruppe ) operated in the Indian Ocean from Japanese bases in the occupied Dutch East Indies and Malaya . Allied convoys had not yet been organised in those waters, so initially many ships were sunk. However, this situation

8211-483: The development and refinement of tactics that came to be called the line of battle . The next stage in the evolution of naval warfare was the introduction of metal plating along the hull sides. The increased mass required steam-powered engines, resulting in an arms race between armor and weapon thickness and firepower. The first armored vessels, the French Gloire and British HMS  Warrior , made wooden vessels obsolete. Another significant improvement came with

8330-630: The early 14th century, the word "navy" came via Old French navie , "fleet of ships", from the Latin navigium , "a vessel, a ship, bark, boat", from navis , "ship". The word "naval" came from Latin navalis , "pertaining to ship"; cf. Greek ναῦς ( naus ), "ship", ναύτης ( nautes ), "seaman, sailor". The earliest attested form of the word is in the Mycenaean Greek compound word 𐀙𐀄𐀈𐀗 , na-u -do-mo (* naudomoi ), "shipbuilders", written in Linear B syllabic script. The word formerly denoted fleets of both commercial and military nature. In modern usage "navy" used alone always denotes

8449-404: The efficiency of the engines has improved, in terms of fuel, and of how many sailors it takes to operate them. In World War II, ships needed to refuel very often. However, today ships can go on very long journeys without refueling. Also, in World War II, the engine room needed about a dozen sailors to work the many engines, however, today, only about four or five are needed (depending on the class of

8568-614: The enemy vessel so its occupants could be attacked hand-to-hand. Naval warfare continued in this vein through the Middle Ages until the cannon became commonplace and capable of being reloaded quickly enough to be reused in the same battle. In ancient China , large naval battles were known since the Qin dynasty ( also see Battle of Red Cliffs , 208), employing the war junk during the Han dynasty . However, China's first official standing navy

8687-500: The era of the Roman empire , naval forces included marine legionaries for maritime boarding actions . These were troops primarily trained in land warfare, and did not need to be skilled at handling a ship. Much later during the age of sail, a component of marines served a similar role, being ship-borne soldiers who were used either during boarding actions, as sharp-shooters, or in raids along shorelines. The Spanish Infantería de Marina

8806-417: The exception of destroyers and submarines, which are known as boats. The prefix on a ship's name indicates that it is a commissioned ship. An important tradition on board naval vessels of some nations has been the ship's bell . This was historically used to mark the passage of time, as warning devices in heavy fog, and for alarms and ceremonies. The ship's captain, and more senior officers are "piped" aboard

8925-472: The first half of the Battle of the Atlantic , but this tactic was largely abandoned by May 1943 , when U-boat losses mounted. Along with the U-boats, surface commerce raiders (including auxiliary cruisers ) were used to disrupt Allied shipping in the early years of the war, the most famous of these being the heavy cruisers Admiral Graf Spee and Admiral Scheer and the battleship Bismarck . However,

9044-602: The fleeing German civilians of Pomerania and Stettin in March and April 1945. A desperate measure of the Kriegsmarine to fight the superior strength of the Western Allies from 1944 was the formation of the Kleinkampfverbände (Small Battle Units). These were special naval units with frogmen , manned torpedoes, motorboats laden with explosives and so on. The more effective of these weapons and units were

9163-456: The following, in ascending order ( Commonwealth ranks are listed first on each line; USA ranks are listed second in those instances where they differ from Commonwealth ranks): "Flag officers" include any rank that includes the word "admiral" (or commodore in services other than the US Navy), and are generally in command of a battle group , strike group or similar flotilla of ships, rather than

9282-797: The guise of enforcing non-intervention , but in reality supporting the Nationalists against the Spanish Republicans . In January 1939, Plan Z , a massive shipbuilding programme, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building programme for submarines ( U-boats ) instead of capital surface warships, and land and air forces were given priority of strategic resources. The Commander-in-Chief of

9401-543: The invention of the rotating turrets, which allowed the guns to be aimed independently of ship movement. The battle between CSS  Virginia and USS  Monitor during the American Civil War (1861–1865) is often cited as the beginning of this age of maritime conflict. The Russian Navy was considered the third strongest in the world on the eve of the Russo-Japanese War , which turned to be

9520-455: The latter bearing the distinction of firing the opening shots of World War II. Zähringen and Hessen were converted into radio-guided target ships in 1928 and 1930 respectively. Hannover was decommissioned in 1931 and struck from the naval register in 1936. Plans to convert her into a radio-controlled target ship for aircraft was cancelled because of the outbreak of war in 1939. Three O-class battlecruisers were ordered in 1939, but with

9639-557: The loss of Admiral Graf Spee at the Battle of the River Plate . Submarine attacks on Britain's vital maritime supply routes ( Battle of the Atlantic ) started immediately at the outbreak of war, although they were hampered by the lack of well placed ports from which to operate. Throughout the war the Kriegsmarine was responsible for coastal artillery protecting major ports and important coastal areas. It also operated anti-aircraft batteries protecting major ports. In April 1940,

9758-513: The mass of the allied freighters reached their destination in Soviet ports. The Battle of the Barents Sea in December 1942 was an attempt by a German naval surface force to attack an Allied Arctic convoy. However, the advantage was not pressed home and they returned to base. There were serious implications: this failure infuriated Hitler, who nearly enforced a decision to scrap the surface fleet. Instead, resources were diverted to new U-boats, and

9877-732: The media that there had been negotiations between Turkey, IvS and Dutch shipyards about a potential order for another four submarines, however, due financial concerns it came to nothing. The E-1 also attracted the attention of the Soviet Navy ; with significant modifications the E-1 became the E-2 project. Construction of the first two prototypes started in December 1934 at the Baltic Shipyard in Leningrad , using German diesel engines and electric batteries . They were followed by

9996-595: The naval versions of two key early war Luftwaffe aircraft: the Messerschmitt Bf 109 T fighter and the Junkers Ju 87 C Stuka dive bomber. The Kriegsmarine completed four battleships during its existence. The first pair were the 11-inch gun Scharnhorst class , consisting of the Scharnhorst and Gneisenau , which participated in the invasion of Norway in 1940, and then in commerce raiding until

10115-495: The number of Allied ships sunk started to decrease. Radar, longer range air cover, sonar , improved tactics, and new weapons all contributed. German technical developments, such as the Schnorchel , attempted to counter these. Near the end of the war a small number of the new Elektroboot U-boats (types XXI and XXIII ) became operational, the first submarines designed to operate submerged at all times. The Elektroboote had

10234-458: The number of ships included, a single ship being the smallest operational unit. Ships may be combined into squadrons or flotillas , which may be formed into fleets . The largest unit size may be the whole Navy or Admiralty . A task force can be assembled using ships from different fleets for an operational task. Despite their acceptance in many areas of naval service, female sailors were not permitted to serve on board U.S. submarines until

10353-479: The numerous United States carrier battle groups . Only two nations, the United States and France , presently operate CATOBAR carriers of any size, while Russia , China and India operate sizeable STOBAR carriers (although all three are originally of Russian design). The United Kingdom is also operating two Queen Elizabeth -class carriers, which are the largest STOVL vessels in service, and India

10472-544: The possibility of winning a war against Great Britain at sea in the coming years. Therefore, he ordered plans for such a fleet from the Kriegsmarine . From the three proposed plans (X, Y and Z) he approved Plan Z in January 1939. This blueprint for the new German naval construction program envisaged building a navy of approximately 800 ships during the period 1939–1947. Hitler demanded that the program be completed by 1945. The main force of Plan Z were six H-class battleships . In

10591-529: The potential to negate the Allied technological and tactical advantage, although they were deployed too late to see combat in the war. Following the capture of Liepāja in Latvia by the Germans on 29 June 1941, the town came under the command of the Kriegsmarine . On 1 July 1941, the town commandant Korvettenkapitän Stein ordered that ten hostages be shot for every act of sabotage, and further put civilians in

10710-432: The prow of the ship. Firing a cannon salute partially disarms the ship, so firing a cannon for no combat reason showed respect and trust. As the tradition evolved, the number of cannons fired became an indication of the rank of the official being saluted. Historically, navy ships were primarily intended for warfare. They were designed to withstand damage and to inflict the same, but only carried munitions and supplies for

10829-418: The radio transmitter, or the flashing light when radio silence was needed. A " blue water navy " is designed to operate far from the coastal waters of its home nation. These are ships capable of maintaining station for long periods of time in deep ocean, and will have a long logistical tail for their support. Many are also nuclear powered to save having to refuel. By contrast a " brown water navy " operates in

10948-645: The rank of Fleet Admiral in the U.S. Navy, the chief of the Royal Australian Navy holds the rank of Vice Admiral, and the chief of the Irish Naval Service holds the rank of Commodore. Naval infantry, commonly known as marines , are a category of infantry that form part of a state's naval forces and perform roles on land and at sea, including amphibious operations , as well as other, naval roles. They also perform other tasks, including land warfare, separate from naval operations. During

11067-456: The region. The heavy cruisers Deutschland and Admiral Scheer , and the light cruiser Köln were the first to be sent in July 1936. These large ships were accompanied by the 2nd Torpedo-boat Flotilla. The German presence was used to covertly support Francisco Franco's Nationalists although the immediate involvement of the Deutschland was humanitarian relief operations and evacuating 9,300 refugees, including 4,550 German citizens. Following

11186-715: The seafaring local people (either Malays of Srivijaya or Javanese of Mataram ) to attack as far as the coast of Tanzania and Mozambique with 1000 boats and attempted to take the citadel of Qanbaloh, about 7,000 km to their West, in 945–946 AD. In 1350 AD Majapahit launched its largest military expedition, the invasion of Pasai , with 400 large jong and innumerable smaller vessels. The second largest military expedition, invasion of Singapura in 1398, Majapahit deployed 300 jong with no less than 200,000 men. The average jong used by Majapahit would be about 76.18–79.81 m LOA , carrying 600–700 men, with 1200–1400 tons deadweight . The mass and deck space required to carry

11305-631: The service of Allied navies that lacked surface ships after the war. The training barque SSS Horst Wessel was recommissioned USCGC Eagle and remains in active service, assigned to the United States Coast Guard Academy . The British, French, and Soviet navies received the destroyers, and some torpedo boats went to the Danish and Norwegian navies. For the purpose of mine clearing, the Royal Navy employed German crews and minesweepers from June 1945 to January 1948, organised in

11424-501: The ship using a Boatswain's call . In the United States, the First Navy Jack is a flag that has the words, "Don't Tread on Me" on the flag. By English tradition, ships have been referred to as a "she". However, it was long considered bad luck to permit women to sail on board naval vessels. To do so would invite a terrible storm that would wreck the ship. The only women that were welcomed on board were figureheads mounted on

11543-507: The ship). Today, naval strike groups on longer missions are always followed by a range of support and replenishment ships supplying them with anything from fuel and munitions, to medical treatment and postal services. This allows strike groups and combat ships to remain at sea for several months at a time. The term "boat" refers to small craft limited in their use by size and usually not capable of making lengthy independent voyages at sea. The old navy adage to differentiate between ships and boats

11662-647: The ships allowed and personnel were taken over from the Kaiserliche Marine , which was renamed the Reichsmarine . From the outset, Germany worked to circumvent the military restrictions of the Treaty of Versailles. The Germans continued to develop U-boats through a submarine design office in the Netherlands ( NV Ingenieurskantoor voor Scheepsbouw ) and a torpedo research program in Sweden where

11781-649: The simultaneous and rapid build-up of the German Army and Air Force which demanded substantial effort and resources. Some projects, like the D-class cruisers and the P-class cruisers , had to be cancelled. The first military action of the Kriegsmarine came during the Spanish Civil War (1936–1939). Following the outbreak of hostilities in July 1936 several large warships of the German fleet were sent to

11900-617: The start of the war the same year there were not enough resources to build the ships. Navy A navy , naval force , military maritime fleet , war navy , or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare ; namely, lake -borne, riverine , littoral , or ocean -borne combat operations and related functions. It includes anything conducted by surface ships , amphibious ships, submarines , and seaborne aviation , as well as ancillary support, communications, training, and other fields. The strategic offensive role of

12019-477: The surface fleet became a lesser threat to the Allies. After December 1943 when Scharnhorst had been sunk in an attack on an Arctic convoy in the Battle of North Cape by HMS  Duke of York , most German surface ships in bases at the Atlantic were blockaded in, or close to, their ports as a fleet in being , for fear of losing them in action and to tie up British naval forces. The largest of these ships,

12138-410: The terms of the 1919 Treaty of Versailles, Germany was only allowed a minimal navy of 15,000 personnel, six capital ships of no more than 10,000 tons, six cruisers , twelve destroyers , twelve torpedo boats , and no submarines or aircraft carriers . Military aircraft were also banned, so Germany could have no naval aviation . Under the treaty Germany could only build new ships to replace old ones. All

12257-755: The third prototype in April 1935. With further modifications to use less-expensive Soviet equipment, full production began in 1936 of the Soviet S-class submarines . In 1945 the Soviet submarine S-13 was responsible for the sinking of the German military transport Wilhelm Gustloff and the General von Steuben with heavy losses of life. From 1927 to 1933 four IvS-designed submarines were built by Crichton-Vulcan Oy in Turku , Finland . One of these, CV 707 (later

12376-506: The version of Plan Z drawn up in August 1939, the German fleet was planned to consist of the following ships by 1945: Personnel strength was planned to rise to over 200,000. The planned naval program was not very far advanced by the time World War II began. In 1939 two M-class cruisers and two H-class battleships were laid down and parts for two further H-class battleships and three O-class battlecruisers were in production. The strength of

12495-400: The vessels, and various repair facilities. During times of war temporary bases may be constructed in closer proximity to strategic locations, as it is advantageous in terms of patrols and station-keeping. Nations with historically strong naval forces have found it advantageous to obtain basing rights in other countries in areas of strategic interest. Navy ships can operate independently or with

12614-701: The voyage (rather than merchant cargo). Often, other ships that were not built specifically for warfare, such as the galleon or the armed merchant ships in World War II , did carry armaments. In more recent times, navy ships have become more specialized and have included supply ships, troop transports, repair ships, oil tankers and other logistics support ships as well as combat ships. Modern navy combat ships are generally divided into seven main categories: aircraft carriers , cruisers , destroyers , frigates , corvettes , submarines , and amphibious assault ships . There are also support and auxiliary ships, including

12733-552: The whole Allied strategy. The vast American ship building capabilities and naval forces were however now brought into the war and soon more than offset any losses inflicted by the German submariners. In 1942, the submarine warfare continued on all fronts, and when German forces in the Soviet Union reached the Black Sea , a few submarines were eventually transferred there. In February 1942, the three large warships stationed on

12852-585: The world's total numbers and total tonnage of naval vessels of 1,000 tons or greater. Throughout the rest of the 20th century, the United States Navy would maintain a tonnage greater than that of the next 17 largest navies combined. During the Cold War , the Soviet Navy became a significant armed force, with large numbers of large, heavily armed ballistic missile submarines and extensive use of heavy, long-ranged antisurface missiles to counter

12971-500: The zone of targeting by declaring that Red Army soldiers were hiding among them in civilian attire. On 5 July 1941 Korvettenkapitän Brückner, who had taken over from Stein, issued a set of anti-Jewish regulations in the local newspaper, Kurzemes Vārds . Summarized, the regulations were as follows: On 16 July 1941, Fregattenkapitän Dr. Hans Kawelmacher was appointed the German naval commandant in Liepāja. On 22 July, Kawelmacher sent

13090-465: Was arguably the largest naval battle in history ; it was also the last battle in which battleships played a significant role. By the end of World War II , the carrier had become the dominant force of naval warfare. World War II also saw the United States become by far the largest naval power in the world. In the late 20th and early 21st centuries, the United States Navy possessed over 70% of

13209-601: Was bombed and sunk by Royal Navy aircraft in Bergen, and the Karlsruhe which was sunk off the coast of Kristiansand by a British submarine. The Kriegsmarine did in return sink some British warships during this campaign, including the aircraft carrier HMS  Glorious . The losses in the Norwegian Campaign left only a handful of undamaged heavy ships available for the planned, but never executed, invasion of

13328-482: Was especially important, and common, before 20th-century military technology existed, when merely adding artillery and naval infantry to any sailing vessel could render it fully as martial as any military-owned vessel. Such privateering has been rendered obsolete in blue-water strategy since modern missile and aircraft systems grew to leapfrog over artillery and infantry in many respects; but privateering nevertheless remains potentially relevant in littoral warfare of

13447-411: Was formed in 1537, making it the oldest, current marine force in the world. The British Royal Marines combine being both a ship-based force and also being specially trained in commando frogman -style operations and tactics, operating in some cases separately from the rest of the Royal Navy. The Royal Marines also have their own special forces unit . In the majority of countries, the marine force

13566-553: Was heavily engaged in providing artillery support to the retreating German land forces along the Baltic coast and in ferrying civilian refugees to the western Baltic Sea parts of Germany ( Mecklenburg , Schleswig-Holstein ) in large rescue operations. Large parts of the population of eastern Germany fled the approaching Red Army out of fear for Soviet retaliation (mass rapes, killings, and looting by Soviet troops did occur). The Kriegsmarine evacuated two million civilians and troops in

13685-609: Was not established until the Southern Song dynasty in the 12th century, a time when gunpowder was a revolutionary new application to warfare. The Chola Dynasty in Southern India had a navy composed of trade ships transporting armies overseas. The Chola Navy reached its peak under Rajendra I , and was most notably used in invasions of Sri Lanka and Southeast Asia . Nusantaran thalassocracies made extensive use of naval power and technologies. This enabled

13804-517: Was not formally declared, leading to the sinking of the USS ; Reuben James . This course of events were the result of the American decision to support Britain with its Lend-Lease program and the subsequent decision to escort Lend-Lease convoys with US war ships through the western part of the Atlantic. The Japanese attack on Pearl Harbor and the subsequent German declaration of war against

13923-462: Was sentenced to 10 years in prison, reduced to 7 years on appeal, for the illegal sinking of ships and criminal negligence for failing to protect the downed crew of the SS Anglo Saxon . Ruckteschell died in prison in 1948. After the war, the German surface ships that remained afloat (only the cruisers Prinz Eugen and [Nürnberg] Error: {{Lang}}: invalid parameter: |4= ( help ) , and

14042-520: Was soon remedied. During the later war years, the Monsun Boats were also used as a means of exchanging vital war supplies with Japan. During 1943 and 1944, due to Allied anti-submarine tactics and better equipment, the U-boat fleet started to suffer heavy losses. The turning point of the Battle of the Atlantic was during Black May in 1943, when the U-boat fleet started suffering heavy losses and

14161-422: Was subsequently scuttled after being rendered a burning wreck by two British battleships. In November 1941 during the Battle of the Mediterranean, German submarine U-331 sank the British battleship Barham , which had a magazine explosion and sank in minutes, with the loss of 862, or 2/3 of her crew. During 1941, the Kriegsmarine and the United States Navy became de facto belligerents , although war
