Naval aviation / Aeronaval is the application of military air power by navies , whether from warships that embark aircraft, or land bases. It often involves navalised aircraft , specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards , such as in U.S. naval aviators .

152-680: The United States Armed Forces are the military forces of the United States . The armed forces consist of six service branches : the Army , Marine Corps , Navy , Air Force , Space Force , and Coast Guard . All six armed services are among the eight uniformed services of the United States , along with the U.S. Public Health Service Commissioned Corps and the NOAA Commissioned Officer Corps . Each of

304-499: A flight deck on the fore-deck; in 1917 it was reconstructed with separate flight decks fore and aft of the superstructure; then finally, after the war, it was heavily reconstructed with a three-quarter length main flight deck, and a lower-level take-off only flight deck on the fore-deck. On 2 August 1917, Squadron Commander E.H. Dunning , Royal Navy, landed his Sopwith Pup aircraft on Furious in Scapa Flow , Orkney , becoming

456-555: A childhood background of relative socio-economic deprivation .  For example, after the US suspended conscription in 1973, "the military disproportionately attracted African American men, men from lower-status socioeconomic backgrounds, men who had been in nonacademic high school programs, and men whose high school grades tended to be low". However, a study released in 2020 on the socio-economic backgrounds of U.S. Armed Forces personnel suggests that they are at parity or slightly higher than

608-583: A civilian job while training under military discipline at weekends; he or she may be called out to deploy on operations to supplement the full-time personnel complement. After leaving the armed forces, recruits may remain liable for compulsory return to full-time military employment in order to train or deploy on operations . Military law introduces offences not recognized by civilian courts, such as absence without leave (AWOL) , desertion, political acts, malingering , behaving disrespectfully, and disobedience (see, for example, offences against military law in

760-403: A country's seagoing forces with air cover over areas that may not be reachable by land-based aircraft, giving them a considerable advantage over navies composed primarily of surface combatants. Naval aviation also provides countries with the opportunity to deploy military aircraft over land and sea, without the need for air bases on land. Aircraft may be used to conduct naval mine clearance ,

912-525: A huge influence on Asian military doctrine, and from the late 19th century, on European and United States military planning . It has even been used to formulate business tactics, and can even be applied in social and political areas. The Classical Greeks and the Romans wrote prolifically on military campaigning . Among the best-known Roman works are Julius Caesar 's commentaries on the Gallic Wars , and

1064-643: A manned reconnaissance device that would give the viewer the advantage of considerable height. In 1908 Prime Minister H. H. Asquith approved the formation of an "Aerial Sub-Committee of the Committee of Imperial Defence " to investigate the potential for naval aviation. In 1909 this body accepted the proposal of Captain Reginald Bacon made to the First Sea Lord Sir John Fisher that rigid airships should be constructed for

1216-595: A military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. A nation's military may function as a discrete social subculture , with dedicated infrastructure such as military housing, schools , utilities, logistics , hospitals , legal services, food production, finance, and banking services. Beyond warfare,

1368-524: A minimum period of service of several years; between two and six years is typical of armed forces in Australia, the UK and the US, for example, depending on role, branch, and rank. Some armed forces allow a short discharge window, normally during training, when recruits may leave the armed force as of right. Alternatively, part-time military employment, known as reserve service , allows a recruit to maintain

1520-403: A more mobile strike capacity led to the development of the aircraft carrier - the backbone of modern naval aviation. HMS  Ark Royal was the first purpose-built seaplane carrier and was also arguably the first modern aircraft carrier. She was originally laid down as a merchant ship, but was converted on the building stocks to be a hybrid airplane/seaplane carrier with a launch platform and

1672-762: A naval zeppelin detachment in Berlin-Johannisthal and an airplane squadron in Putzig (Puck, Poland). The Japanese established the Imperial Japanese Navy Air Service , modelled on the RNAS , in 1913. On 24 January 1913 came the first wartime naval aviation interservice cooperation mission. Greek pilots on a seaplane observed and drew a diagram of the positions of the Turkish fleet against which they dropped four bombs. This event

1824-569: A platform extending from the side of the flight deck. In the United States, Admiral William Benson attempted to entirely dissolve the USN's Naval Aeronautics program in 1919. Assistant Secretary of the Navy Franklin Roosevelt and others succeeded in maintaining it, but the service continued to support battleship-based doctrines. To counter Billy Mitchell 's campaign to establish a separate Department of Aeronautics, Secretary of

1976-755: A seaplane carrier against a land target as well as a sea target took place in September 1914 when the Imperial Japanese Navy carrier Wakamiya conducted ship-launched air raids from Kiaochow Bay during the Battle of Tsingtao in China. The four Maurice Farman seaplanes bombarded German-held land targets (communication centers and command centers) and damaged a German minelayer in the Tsingtao peninsula from September until 6 November 1914, when

2128-464: A sense of military tradition , which is used to create cohesive military forces. Still, another is to learn to prevent wars more effectively. Human knowledge about the military is largely based on both recorded and oral history of military conflicts (war), their participating armies and navies and, more recently, air forces . Despite the growing importance of military technology , military activity depends above all on people. For example, in 2000

2280-605: A ship which was under way occurred. Hibernia steamed at 10.5 knots (19.4 km/h; 12.1 mph) at the Royal Fleet Review in Weymouth Bay , England . Hibernia then transferred her aviation equipment to battleship London . Based on these experiments, the Royal Navy concluded that aircraft were useful aboard ship for spotting and other purposes, but that interference with the firing of guns caused by

2432-618: A significant impact at the strategic level. This concept was pioneered by the German army prior to and during the Second World War . At this level, planning and duration of activities takes from one week to a month, and are executed by Field Armies and Army Corps and their naval and air equivalents. Military tactics concerns itself with the methods for engaging and defeating the enemy in direct combat. Military tactics are usually used by units over hours or days, and are focused on

2584-681: A single organization. The mission of Army Aviation is to find, fix and destroy any enemy through fire and maneuver and to provide combat support and combat service support in coordinated operations as an integral member of the combined arms team. Major aircraft include the AH-64 Apache , which serves as the Army's attack helicopter, the UH-60 Black Hawk , and the CH-47 Chinook for troop and cargo transport. Army Aviation also flies

2736-459: A small number of aircraft. The solution to the problem were large numbers of mass-produced merchant hulls converted into escort aircraft carriers (also known as "jeep carriers"). These basic vessels, unsuited to fleet action by their capacity, speed and vulnerability, nevertheless provided air cover where it was needed. The Royal Navy had observed the impact of naval aviation and, obliged to prioritise their use of resources, abandoned battleships as

2888-455: A special operations force, Army Rangers are generally better equipped than standard infantry, utilizing the FN SCAR rifle. Army Special Forces , commonly known as Green Berets after their iconic headgear, are among the most elite soldiers in the Army. Special Forces conduct: Army Special Forces are trained in military free-fall parachuting and combat diver skillsets. They are considered

3040-643: A very close relationship with the U.S. Navy, its sister service in the Department of the Navy. Although the Marine Corps has previously operated as an independent land force alongside the Army, its primary purpose is to serve as part of a unified naval service alongside the Navy in the maritime domain. The U.S. Marine Corps is organized under the Department of the Navy , which is a military department under

3192-653: A victory more often than that achieved by the Romans in praying to the gods before the battle. Later this became known as military science , and later still, would adopt the scientific method approach to the conduct of military operations under the influence of the Industrial Revolution thinking. In his seminal book On War , the Prussian Major-General and leading expert on modern military strategy , Carl von Clausewitz defined military strategy as 'the employment of battles to gain

3344-560: Is a method of supplying naval vessels at sea, by helicopter . This means moving cargo and supplies from supply ships to the flight decks of other naval vessels using naval helicopters. During the Cold War , the navies of NATO faced a significant threat from Soviet submarine forces, specifically Soviet Navy SSN and SSGN assets. This resulted in the development and deployment of light aircraft carriers with major anti-submarine warfare (ASW) capabilities by European NATO navies. One of

3496-612: Is also a law enforcement agency. From their inception during the American Revolutionary War , the U.S. Armed Forces have played a decisive role in the country's history . They helped forge a sense of national unity and identity through victories in the early-19th-century First and Second Barbary Wars . They played a critical role in the territorial evolution of the U.S. , including the American Civil War . The National Security Act of 1947 created

3648-431: Is also an area in which much effort is invested – it includes everything from global communication networks and aircraft carriers to paint and food. Possessing military capability is not sufficient if this capability cannot be deployed for, and employed in combat operations. To achieve this, military logistics are used for the logistics management and logistics planning of the forces military supply chain management ,

3800-416: Is also used as part of amphibious warfare . Aircraft based on naval ships provide support to marines and other forces performing amphibious landings. Ship-based aircraft may also be used to support amphibious forces as they move inland. Naval aircraft are used for various maritime patrol missions, such as reconnaissance, search and rescue, and maritime law enforcement. Vertical replenishment (VERTREP)

3952-407: Is arguably one of the most complex activities known to humanity; because it requires determining: strategic, operational, and tactical capability requirements to counter the identified threats; strategic, operational , and tactical doctrines by which the acquired capabilities will be used; identifying concepts, methods, and systems involved in executing the doctrines; creating design specifications for

4104-405: Is conducted by determining a military budget , which is administered by a military finance organization within the military. Military procurement is then authorized to purchase or contract provision of goods and services to the military, whether in peacetime at a permanent base, or in a combat zone from local population. Capability development, which is often referred to as the military 'strength',

4256-571: Is in the nature of the secrecy of the information they seek, and the clandestine nature that intelligence operatives work in obtaining what may be plans for a conflict escalation , initiation of combat , or an invasion . An important part of the military intelligence role is the military analysis performed to assess military capability of potential future aggressors, and provide combat modelling that helps to understand factors on which comparison of forces can be made. This helps to quantify and qualify such statements as: " China and India maintain

4408-555: Is led by the chairman of the Joint Chiefs of Staff , who is the military head of the armed forces and principal advisor to the president and secretary of defense on military matters. Their deputy is the vice chairman of the Joint Chiefs of Staff . Other members include the chief of staff of the Army , commandant of the Marine Corps , chief of naval operations , chief of staff of the Air Force , chief of space operations , and

4560-630: Is now one of the eight uniformed services of the United States. Should it be called into active duty again, it would constitute a seventh branch of the Armed Forces. The United States Space Force was established as an independent service on 20 December 2019. It is the sixth branch of the U.S. military and the first new branch in 72 years. The origin of the Space Force can be traced back to the Air Force Space Command , which

4712-525: Is the world's 12th-largest maritime force. The history of the U.S. Armed Forces dates back to 14 June 1775, with the creation of the Continental Army , even before the Declaration of Independence marked the establishment of the United States. The Continental Navy , established on 13 October 1775, and Continental Marines , established on 10 November 1775, were created in close succession by

The three primary missions of the 75th Ranger Regiment are special operations raids , forcible entry operations, such as an airfield seizure to enable the Air Force to bring in more forces, and special reconnaissance . As

5624-567: The Doolittle Raid of 1942, 16 Army medium bombers were launched from the carrier Hornet on one-way missions to bomb Japan. All were lost to fuel exhaustion after bombing their targets and the experiment was not repeated. Smaller carriers were built in large numbers to escort slow cargo convoys or supplement fast carriers. Aircraft for observation or light raids were also carried by battleships and cruisers, while blimps were used to search for attack submarines. Experience showed that there

5776-689: The FIM-92 Stinger man-portable air-defense system , AN/TWQ-1 Avenger for short range air defense , and the counter rocket, artillery, and mortar 20mm gun system.

Militaries are typically authorized and maintained by a sovereign state , with their members identifiable by a distinct military uniform . They may consist of one or more military branches such as an army , navy , air force , space force , marines , or coast guard . The main task of

6536-489: The PBY Catalina helped finding submarines and surface fleets. In World War II the aircraft carrier replaced the battleship as the most powerful naval offensive weapons system as battles between fleets were increasingly fought out of gun range by aircraft. The Japanese Yamato , the heaviest battleship ever built, was first turned back by light escort carrier aircraft and later sunk lacking its own air cover. During

6688-593: The Roman Civil war – written about 50 BC. Two major works on tactics come from the late Roman period: Taktike Theoria by Aelianus Tacticus , and De Re Militari ('On military matters') by Vegetius . Taktike Theoria examined Greek military tactics, and was most influential in the Byzantine world and during the Golden Age of Islam . De Re Militari formed the basis of European military tactics until

6840-666: The Royal Navy to be used for reconnaissance. This resulted in the construction of Mayfly in 1909, the first air component of the navy to become operational, and the genesis of modern naval aviation. The first pilots for the Royal Navy were transferred from the Royal Aero Club in June 1910 along with two aircraft with which to train new pilots, and an airfield at Eastchurch became the Naval Flying School,

6992-735: The Second Continental Congress in order to defend the new nation against the British Empire in the American Revolutionary War . These forces demobilized in 1784 after the Treaty of Paris ended the Revolutionary War. The Congress of the Confederation created the current United States Army on 3 June 1784. The United States Congress created the current United States Navy on 27 March 1794 and

7144-812: The United States Navy to demonstrate that airplanes could take off from and land aboard ships at sea. One of his pilots, Eugene Ely , took off from the cruiser USS  Birmingham anchored off the Virginia coast in November 1910. Two months later Ely landed aboard another cruiser, USS  Pennsylvania , in San Francisco Bay , proving the concept of shipboard operations. However, the platforms erected on those vessels were temporary measures. The U.S. Navy and Glenn Curtiss experienced two firsts during January 1911. On 27 January, Curtiss flew

7296-586: The Wright brothers and Curtiss. A camp with a primitive landing field was established on the Severn River at Greenbury Point, near Annapolis, Maryland . The vision of the aerial fleet was for scouting. Each aircraft would have a pilot and observer. The observer would use the wireless radio technology to report on enemy ships. Some thoughts were given to deliver counterattacks on hostile aircraft using "explosives or other means". Using airplanes to bomb ships

7448-552: The chief of the National Guard Bureau . The commandant of the Coast Guard is not an official member of the Joint Chiefs, but sometimes attends meetings as one of the military service chiefs.

Army landpower focuses on destroying an enemy's armed forces, occupying its territory, and breaking the will of an adversary. The five core competencies of the Army are: The thirteen specified functions of the Army are: The Infantry Branch forms the core of

8360-583: The ski-jump ramp as an alternative to contemporary catapult systems. As the Royal Navy retired or sold the last of its World War II-era carriers, they were replaced with smaller ships designed to operate helicopters and the V/STOVL Sea Harrier jet. The ski-jump gave the Harriers an enhanced STOVL capability, allowing them to take off with heavier payloads. In 2013, the US Navy completed

8512-666: The unified combatant commands , and thirteen direct reporting units. The United States Marine Corps (USMC) serves as the U.S. Armed Forces' naval land force, responsible for executing amphibious warfare and operating in the maritime littorals in support of the U.S. Navy.

The military organization is characterized by a command hierarchy divided by military rank , with ranks normally grouped (in descending order of authority) as officers (e.g. colonel ), non-commissioned officers (e.g. sergeant ), and personnel at the lowest rank (e.g. private ). While senior officers make strategic decisions, subordinated military personnel ( soldiers , sailors , marines , or airmen ) fulfil them. Although rank titles vary by military branch and country,

9120-572: The Department of Defense's military departments. The United States Coast Guard is nominally under the Department of Homeland Security , but may be transferred to the Department of Defense's Department of the Navy (which is the civilian entity that oversees the coequal U.S. Marine Corps and U.S. Navy) at the direction of the President or Congress. With the exception of the Coast Guard, the military services only organize, train, and equip forces. The unified combatant commands are responsible for operational control of non-service retained forces. Each of

9272-420: The Germans surrendered. One Japanese plane was credited being shot down by the German aviator Gunther Plüschow in an Etrich Taube , using his pistol. On the Western front the first naval air raid occurred on 25 December 1914 when twelve seaplanes from HMS  Engadine , Riviera and Empress ( cross-channel steamers converted into seaplane carriers) attacked the Zeppelin base at Cuxhaven .

When the intelligence reporting is compared to the policy, it becomes possible for

9576-469: The Navy Josephus Daniels ordered a rigged test against USS  Indiana in 1920 which reached the conclusion that "the entire experiment pointed to the improbability of a modern battleship being either destroyed or completely put out of action by aerial bombs." Investigation by the New-York Tribune that discovered the rigging led to Congressional resolutions compelling more honest studies . The sinking of SMS  Ostfriesland involved violating

9728-437: The Navy's rules of engagement but completely vindicated Mitchell to the public. Some men, such as Captain (soon Rear Admiral) William A. Moffett , saw the publicity stunt as a means to increase funding and support for the Navy's aircraft carrier projects. Moffett was sure that he had to move decisively in order to avoid having his fleet air arm fall into the hands of a proposed combined Land/Sea Air Force which took care of all

9880-443: The President of the United States to the secretary of defense (for services under the Defense Department) or secretary of homeland security (for services under the Department of Homeland Security), ensuring civilian control of the military .

Certain rights are also restricted or suspended, including the freedom of association (e.g. union organizing) and freedom of speech (speaking to the media). Military personnel in some countries have a right of conscientious objection if they believe an order is immoral or unlawful, or cannot in good conscience carry it out. Personnel may be posted to bases in their home country or overseas, according to operational need, and may be deployed from those bases on exercises or operations . During peacetime, when military personnel are generally stationed in garrisons or other permanent military facilities, they conduct administrative tasks, training and education activities, technology maintenance , and recruitment . Initial training conditions recruits for

10488-418: The United States is the United States Armed Forces' commander-in-chief . The United States Coast Guard traces its origin to the formation of the Revenue Cutter Service on 4 August 1790, which merged with the United States Life-Saving Service on 28 January 1915 to establish the Coast Guard. The United States Air Force was established as an independent service on 18 September 1947; it traces its origin to

The United States Armed Forces are split between two cabinet departments, with the Department of Defense serving as the primary cabinet department for military affairs and the Department of Homeland Security responsible for administering the United States Coast Guard . The military chain of command flows from

10944-508: The War. The first jet landing on a carrier was made by Lt Cdr Eric 'Winkle' Brown who landed on HMS  Ocean in the specially modified de Havilland Vampire ( registration LZ551/G) on 3 December 1945. Following the introduction of angled flight decks , jets were regularly operating from carriers by the mid-1950s. An important development of the early 1950s was the British invention of

11096-600: The Western Front. In 1914 the first aerial torpedo was dropped in trials performed in a Short "Folder" by Lieutenant (later Air Chief Marshal Sir) Arthur Longmore , and in August 1915, a Short Type 184 piloted by Flight Commander Charles Edmonds from HMS  Ben-my-Chree sank a Turkish supply ship in the Sea of Marmara with a 14-inch-diameter (360 mm), 810-pound (370 kg) torpedo. The first strike from

Aircraft operated by navies are also used in the anti-surface warfare (ASUW or ASuW) role, to attack enemy ships and other, surface combatants . This is generally conducted using air-launched anti-ship missiles . Naval aviation

11552-499: The aircraft. The Gnome -engined Short Improved S.27 "S.38", pusher seaplane piloted by Lieutenant Charles Samson become the first British aircraft to take-off from a ship while at anchor in the River Medway , on 10 January 1912. Africa then transferred her flight equipment to her sister ship Hibernia . In May 1912, with Commander Samson again flying the "S.38", the first ever instance of an aircraft to take off from

11704-489: The angled flight deck by Capt D.R.F. Campbell RN in conjunction with Lewis Boddington of the Royal Aircraft Establishment at Farnborough. The runway was canted at an angle of a few degrees from the longitudinal axis of the ship. If an aircraft missed the arrestor cables (referred to as a " bolter "), the pilot only needed to increase engine power to maximum to get airborne again, and would not hit

11856-531: The armed forces and forms military policy with the DoD and Department of Homeland Security (DHS), both federal executive departments , acting as the principal organs by which military policy is carried out. The U.S. Armed Forces are one of the world's largest military forces in terms of personnel. They draw their personnel from a large pool of professional volunteers . The U.S. has used military conscription , but not since 1973. The Selective Service System retains

12008-497: The armed forces, and at all levels of the military hierarchy of command. Although concerned with research into military psychology , particularly combat stress and how it affects troop morale , often the bulk of military science activities is directed at military intelligence technology, military communications , and improving military capability through research. The design, development, and prototyping of weapons , military support equipment, and military technology in general,

12160-460: The capacity to hold up to four wheeled aircraft. Launched on 5 September 1914, she served in the Dardanelles campaign and throughout World War I. During World War I the Royal Navy also used HMS Furious to experiment with the use of wheeled aircraft on ships. This ship was reconstructed three times between 1915 and 1925: first, while still under construction, it was modified to receive

12312-513: The civilian population with respect to socio-economic indicators such as parental income, parental wealth and cognitive abilities. The study found that technological, tactical, operational and doctrinal changes have led to a change in the demand for personnel. Furthermore, the study suggests that the most disadvantaged socio-economic groups are less likely to meet the requirements of the modern U.S. military. The obligations of military employment are many. Full-time military employment normally requires

12464-409: The coequal military service branches organized within each department. The military departments and services are responsible for organizing, training, and equipping forces, with the actual chain of command flowing through the unified combatant commands . The Joint Chiefs of Staff , although outside the operational chain of command, is the senior-most military body in the United States Armed Forces. It

12616-592: The commanding forces and other military, as well as often civilian personnel participate in identification of these threats. This is at once an organization, a system and a process collectively called military intelligence (MI). Areas of study in Military intelligence may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. The difficulty in using military intelligence concepts and military intelligence methods

12768-454: The concepts and methods used by the command to employ appropriately military skilled, armed and equipped personnel in achievement of the tangible goals and objectives of the war , campaign , battle , engagement, and action. The line between strategy and tactics is not easily blurred, although deciding which is being discussed had sometimes been a matter of personal judgement by some commentators, and military historians. The use of forces at

12920-410: The concerns of military command. Military strategy is more concerned with the supply of war and planning, than management of field forces and combat between them. The scope of strategic military planning can span weeks, but is more often months or even years. Operational mobility is, within warfare and military doctrine , the level of command which coordinates the minute details of tactics with

13072-676: The conduct of other military activities related to countering threats to U.S. national security. This mission is focused on providing support to echelons at the CCMD level and below and may not encompass the full scope of the CSA's mission. The United States Armed Forces is composed of six coequal military service branches. Five of the branches, the United States Army , United States Marine Corps , United States Navy , United States Air Force , and United States Space Force , are organized under

13224-512: The consumables, and capital equipment of the troops. Although mostly concerned with the military transport , as a means of delivery using different modes of transport; from military trucks , to container ships operating from permanent military base , it also involves creating field supply dumps at the rear of the combat zone, and even forward supply points in a specific unit's tactical area of responsibility . These supply points are also used to provide military engineering services, such as

13376-648: The conversion of the collier USS Jupiter and its recommissioning as USS  Langley in 1922. Many British naval vessels carried float planes, seaplanes or amphibians for reconnaissance and spotting: two to four on battleships or battlecruisers and one on cruisers. The aircraft, a Fairey Seafox or later a Supermarine Walrus , were catapult-launched , and landed on the sea alongside for recovery by crane. Several submarine aircraft carriers were built by Japan, each carrying one floatplane, which did not prove effective in war. The French Navy built one large submarine , Surcouf , which also carried one floatplane, and

13528-474: The course of the war, seaborne aircraft were used in fleet actions at sea ( Midway , Bismarck ), strikes against naval units in port ( Taranto , Pearl Harbor ), support of ground forces ( Okinawa , Allied invasion of Italy ) and anti-submarine warfare (the Battle of the Atlantic ). Carrier-based aircraft were specialised as dive bombers , torpedo bombers , and fighters . Surface-based aircraft such as

13680-601: The cruiser Hermes converted into a seaplane carrier . In 1914, naval aviation was split again, and became the Royal Naval Air Service . However, shipboard naval aviation had begun in the Royal Navy, and would become a major part of fleet operations by 1917. Other early operators of seaplanes were Germany , within its Marine-Fliegerabteilung naval aviation units within the Kaiserliche Marine , and Russia . In May 1913 Germany established

13832-473: The current United States Marine Corps on 11 July 1798. All three services trace their origins to their respective Continental predecessors. The 1787 adoption of the Constitution gave Congress the power to "raise and support armies," to "provide and maintain a navy", and to "make rules for the government and regulation of the land and naval forces", as well as the power to declare war . The President of

13984-609: The demands of carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat , surface attack , submarine attack , search and rescue , matériel transport, weather observation , reconnaissance and wide area command and control duties. Naval helicopters can be used for many of

14136-429: The demands of military life, including preparedness to injure and kill other people, and to face mortal danger without fleeing. It is a physically and psychologically intensive process which resocializes recruits for the unique nature of military demands. For example: The next requirement comes as a fairly basic need for the military to identify possible threats it may be called upon to face. For this purpose, some of

14288-547: The development of the optimum design for other aircraft carriers. Argus also evaluated various types of arresting gear , general procedures needed to operate a number of aircraft in concert, and fleet tactics. The Tondern raid , a British bombing raid against the Imperial German Navy 's airship base at Tønder , Denmark was the first attack in history made by aircraft flying from a carrier flight deck, with seven Sopwith Camels launched from HMS Furious . For

14440-422: The different military services is assigned a role and domain. The Army conducts land operations. The Navy and Marine Corps conduct maritime operations, the Marine Corps specializing in amphibious and maritime littoral operations primarily for supporting the Navy. The Air Force conducts air operations. The Space Force conducts space operations. The Coast Guard is unique in that it specializes in maritime operations and

14592-401: The different military services is assigned a role and domain. The U.S. Army conducts land operations, while the U.S. Navy and U.S. Marine Corps conduct maritime operations, with the Marine Corps specializing in amphibious and maritime littoral operations in support of the Navy. The U.S. Air Force conducts air operations, while the U.S. Space Force conducts space operations. The U.S. Coast Guard

14744-414: The end of war'. According to Clausewitz: strategy forms the plan of the War, and to this end it links together the series of acts which are to lead to the final decision, that is to say, it makes the plans for the separate campaigns and regulates the combats to be fought in each. Hence, Clausewitz placed political aims above military goals , ensuring civilian control of the military . Military strategy

14896-401: The existence of the military is to engage in combat , should it be required to do so by the national defence policy, and to win. This represents an organisational goal of any military, and the primary focus for military thought through military history . How victory is achieved, and what shape it assumes, is studied by most, if not all, military groups on three levels. Military strategy is

15048-593: The expensive connotations of the term "aircraft carrier", the Invincible -class carriers were originally designated as "through deck cruisers" and were initially to operate as helicopter-only craft escort carriers. The arrival of the Sea Harrier VTOL / STOVL fast jet meant that the Invincible-class could carry fixed-wing aircraft, despite their short flight decks. The British also introduced

15200-464: The first seaplane from the water at San Diego Bay and the next day U.S. Navy Lt. Theodore G. Ellyson , a student at the nearby Curtiss School, took off in a Curtiss "grass cutter" plane to become the first naval aviator . $ 25,000 was appropriated for the Bureau of Navigation (United States Navy) to purchase three airplanes and in the spring of 1911 four additional officers were trained as pilots by

15352-536: The first catapult launching from a ship underway. The first permanent naval air station was established at Pensacola, Florida , in January 1914 with Mustin as its commanding officer. On April 24 of that year, and for a period of approximately 45 days afterward, five floatplanes and flying boats flown by ten aviators operated from Mississippi and the cruiser Birmingham off Veracruz and Tampico , Mexico, respectively, conducting reconnaissance for troops ashore in

15504-654: The first naval units solely destroyed by airplanes. During the war the German "Marineflieger" claimed the destruction of 270 enemy planes, 6 balloons, 2 airships, 1 Russian destroyer, 4 merchant ships, 3 submarines, 4 torpedo boats and 12 vehicles, for the loss of 170 German sea and land planes as well as 9 vehicles. Notable Marineflieger aces were Gotthard Sachsenberg (31 victories), Alexander Zenzes (18 victories), Friedrich Christiansen (13 victories, 1 airship and 1 submarine), Karl Meyer (8 victories), Karl Scharon (8 victories), and Hans Goerth (7 victories). The need for

15656-421: The first person to land a plane on a moving ship. He was killed five days later during another landing on Furious . HMS  Argus was converted from an ocean liner and became the first example of what is now the standard pattern of aircraft carrier, with a full-length flight deck that allowed wheeled aircraft to take off and land. After commissioning , the ship was heavily involved for several years in

15808-777: The first successful catapult launch and arrested landing of an unmanned aerial vehicle (UAV) aboard an aircraft carrier. After a decade of research and planning, the US Navy has been testing the integration of UAVs with carrier-based forces since 2013, using the experimental Northrop Grumman X-47B , and is working to procure a fleet of carrier-based UAVs, referred to as the Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS) system. Naval aviation forces primarily perform naval roles at sea. However, they are also used for other tasks which vary between states. Common roles for such forces include: Carrier-based naval aviation provides

15960-527: The first such facility in the world. Two hundred applications were received, and four were accepted: Lieutenant C R Samson , Lieutenant A M Longmore , Lieutenant A Gregory and Captain E L Gerrard , RMLI . The French also established a naval aviation capability in 1910 with the establishment of the Service Aeronautique and the first flight training schools. U.S. naval aviation began with pioneer aviator Glenn Curtiss who contracted with

16112-451: The force around the world, including around 800 military bases outside the U.S. The U.S. Air Force is the world's largest air force, followed by the U.S. Army Aviation Branch . The U.S. Naval Air Forces is the fourth-largest air arm in the world and is the largest naval aviation service, while U.S. Marine Corps Aviation is the world's seventh-largest air arm. The U.S. Navy is the world's largest navy by tonnage . The U.S. Coast Guard

16264-793: The form of military camouflage or misdirection using decoys , is used to confuse the enemy as a tactic. A major development in infantry tactics came with the increased use of trench warfare in the 19th and 20th centuries. This was mainly employed in World War I in the Gallipoli campaign , and the Western Front . Trench warfare often turned to a stalemate, only broken by a large loss of life, because, in order to attack an enemy entrenchment, soldiers had to run through an exposed ' no man's land ' under heavy fire from their opposing entrenched enemy. As with any occupation, since ancient times,

16416-608: The formation of the Aeronautical Division, U.S. Signal Corps , which was formed 1 August 1907 and was part of the Army Air Forces before being recognized as an independent service in the National Security Act of 1947. The United States Public Health Service Commissioned Corps was formerly considered to be a branch of the United States Armed Forces from 29 July 1945 until 3 July 1952, and

16568-492: The hydraulic catapults which had been introduced in the 1940s. The first Optical Landing System , the Mirror Landing Aid was invented by Lieutenant Commander H. C. N. Goodhart RN. The first trials of a mirror landing sight were conducted on HMS Illustrious in 1952. The US Navy built the first aircraft carrier to be powered by nuclear reactors . USS  Enterprise was powered by eight nuclear reactors and

16720-517: The largest armed forces in the World" or that "the U.S. Military is considered to be the world's strongest". Although some groups engaged in combat, such as militants or resistance movements , refer to themselves using military terminology, notably 'Army' or 'Front', none have had the structure of a national military to justify the reference, and usually have had to rely on support of outside national militaries. They also use these terms to conceal from

16872-540: The late 17th century. Perhaps its most enduring maxim is Igitur qui desiderat pacem, praeparet bellum (let he who desires peace prepare for war). Due to the changing nature of combat with the introduction of artillery in the European Middle Ages , and infantry firearms in the Renaissance , attempts were made to define and identify those strategies, grand tactics , and tactics that would produce

17024-412: The leadership of the secretary of the Navy and the under secretary of the Navy . The U.S. Marine Corps itself is led by the commandant of the Marine Corps and the assistant commandant of the Marine Corps , both generals who are advised by the sergeant major of the Marine Corps . The Marine Corps statutory mission is outlined in 10 U.S.C.   § 5063 and as originally introduced under

17176-482: The level of organization between strategic and tactical is called operational mobility . Because most of the concepts and methods used by the military, and many of its systems are not found in commercial branches, much of the material is researched, designed, developed, and offered for inclusion in arsenals by military science organizations within the overall structure of the military. Therefore, military scientists can be found interacting with all Arms and Services of

17328-411: The loss of one man, the British destroyed two German zeppelins , L.54 and L.60 and a captive balloon. Genuine aircraft carriers did not emerge beyond Britain until the early 1920s. The Japanese Hōshō (1921) was the world's first purpose-built aircraft carrier, although the initial plans and laying down for HMS  Hermes (1924) had begun earlier. Both Hōshō and Hermes initially boasted

17480-418: The mainstay of the fleet. HMS  Vanguard was therefore the last British battleship and her sisters were cancelled. The United States had already instigated a large construction programme (which was also cut short) but these large ships were mainly used as anti-aircraft batteries or for shore bombardment . Other actions involving naval aviation included: Jet aircraft were used on aircraft carriers after

17632-426: The management of forces in wars and military campaigns by a commander-in-chief , employing large military forces, either national and allied as a whole, or the component elements of armies , navies and air forces ; such as army groups , naval fleets , and large numbers of aircraft . Military strategy is a long-term projection of belligerents' policy, with a broad view of outcome implications, including outside

17784-630: The manufacturers who would produce these in adequate quantity and quality for their use in combat; purchase the concepts, methods, and systems; create a forces structure that would use the concepts, methods, and systems most effectively and efficiently; integrate these concepts, methods, and systems into the force structure by providing military education , training , and practice that preferably resembles combat environment of intended use; create military logistics systems to allow continued and uninterrupted performance of military organizations under combat conditions, including provision of health services to

17936-497: The military has been distinguished from other members of the society by their tools: the weapons and military equipment used in combat. When Stone Age humans first took flint to tip the spear , it was the first example of applying technology to improve the weapon. Since then, the advances made by human societies, and that of weapons, has been closely linked. Stone weapons gave way to Bronze Age and Iron Age weapons such as swords and shields . With each technological change

18088-436: The military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control , promotion of political agendas , emergency services and reconstruction, protecting corporate economic interests, social ceremonies, and national honour guards . The profession of soldiering is older than recorded history . Some images of classical antiquity portray

18240-500: The modern U.S. military framework, establishing the National Military Establishment (later the Department of Defense or DoD) headed by the secretary of defense and creating both the U.S. Air Force and National Security Council ; in 1949, an amendment to the act merged the cabinet-level departments of the Army, Navy, and Air Force into the DoD. The president of the U.S. is the commander-in-chief of

18392-569: The most effective weapons against submarines is the ASW helicopter, several of which could be based on these light ships. These carriers are typically around 20,000 tons displacement and carry a mix of ASW helicopters and fixed wing aircraft. Land-based maritime patrol aircraft are also useful in this role, since they can operate independently of aircraft carriers. Naval aircraft are used to airlift supplies, insert specialized personnel (e.g. medical staff, relief workers), and evacuate persons in distress in

18544-683: The most versatile special operations force in the entire world, operating as a multi-purpose force since 1952. The Armor Branch traces its history back to the United States Cavalry and are responsible for tank and cavalry reconnaissance operations. The U.S. Army fields the M1 Abrams main battle tank in Armored Battalions as part of Armored Brigade Combat Teams across the 1st Armored Division , 1st Cavalry Division , 1st Infantry Division , 3rd Infantry Division , and

18696-425: The national leadership to consider allocating resources over and above the officers and their subordinates military pay, and the expense of maintaining military facilities and military support services for them. Source: SIPRI Defense economics is the financial and monetary efforts made to resource and sustain militaries, and to finance military operations , including war. The process of allocating resources

18848-421: The overarching goals of strategy . A common synonym is operational art. The operational level is at a scale bigger than one where line of sight and the time of day are important, and smaller than the strategic level, where production and politics are considerations. Formations are of the operational level if they are able to conduct operations on their own, and are of sufficient size to be directly handled or have

19000-598: The parked aircraft because the angled deck pointed out over the sea. The angled flight deck was first tested on HMS  Triumph , by painting angled deck markings onto the centerline flight deck for touch and go landings. The modern steam-powered catapult , powered by steam from a ship's boilers or reactors, was invented by Commander C.C. Mitchell of the Royal Naval Reserve . It was widely adopted following trials on HMS  Perseus between 1950 and 1952 which showed it to be more powerful and reliable than

19152-417: The personnel, and maintenance for the equipment; the services to assist recovery of wounded personnel, and repair of damaged equipment; and finally, post-conflict demobilization , and disposal of war stocks surplus to peacetime requirements. Development of military doctrine is perhaps the most important of all capability development activities, because it determines how military forces are used in conflicts,

19304-486: The physicality of armed forces, their personnel , equipment , and the physical area which they occupy. As an adjective, military originally referred only to soldiers and soldiering, but it broadened to apply to land forces in general, and anything to do with their profession. The names of both the Royal Military Academy (1741) and United States Military Academy (1802) reflect this. However, at about

19456-550: The power and feats of military leaders . The Battle of Kadesh in 1274 BC from the reign of Ramses II , features in bas-relief monuments. The first Emperor of a unified China , Qin Shi Huang , created the Terracotta Army to represent his military might. The Ancient Romans wrote many treatises and writings on warfare, as well as many decorated triumphal arches and victory columns . The first recorded use of

19608-612: The power to conscript males, requiring the registration of all male citizens and residents of the U.S. between the ages of 18 and 25. The U.S. Armed Forces are considered the world's most powerful military, especially since the end of the Cold War . The military expenditure of the U.S. was US$ 916 billion in 2023, the highest in the world, accounting for 37% of the world's defense expenditures . The U.S. Armed Forces has significant capabilities in both defense and power projection due to its large budget, resulting in advanced and powerful technologies which enable widespread deployment of

19760-438: The president, to the secretary of defense, to the commanders of the combatant commands. Each service organizes, trains, and equips forces that are then presented to the unified combatant commands through service component commands. Special Operations Command and Cyber Command also present theater special operations commands or joint force headquarters – cyber to other combatant commanders. Army components are typically dual-hatted as

19912-445: The rank hierarchy is common to all state armed forces worldwide. In addition to their rank, personnel occupy one of many trade roles, which are often grouped according to the nature of the role's military tasks on combat operations: combat roles (e.g. infantry ), combat support roles (e.g. combat engineers ), and combat service support roles (e.g. logistical support ). Personnel may be recruited or conscripted , depending on

20064-415: The recovery of defective and derelict vehicles and weapons, maintenance of weapons in the field, the repair and field modification of weapons and equipment; and in peacetime, the life-extension programmes undertaken to allow continued use of equipment. One of the most important role of logistics is the supply of munitions as a primary type of consumable, their storage, and disposal . The primary reason for

20216-724: The runway built over the foredeck and the danger and impracticality of recovering seaplanes that alighted in the water in anything but calm weather more than offset the desirability of having airplanes aboard. In 1912, the nascent naval air detachment in the United Kingdom was amalgamated to form the Royal Flying Corps and in 1913 a seaplane base on the Isle of Grain , an airship base at Kingsnorth and eight new airfields were approved for construction. The first aircraft participation in naval manoeuvres took place in 1913 with

20368-553: The same missions as fixed-wing aircraft while operating from aircraft carriers, helicopter carriers , destroyers and frigates . Early experiments on the use of kites for naval reconnaissance took place in 1903 at Woolwich Common for the Admiralty . Samuel Franklin Cody demonstrated the capabilities of his 8-foot-long black kite and it was proposed for use as either a mechanism to hold up wires for wireless communications or as

20520-778: The service's land combat power. U.S. Army infantry are generally equipped with the M4 carbine and M249 light machine gun , which will be replaced by the XM7 rifle and XM250 . Infantry is a core part of the Army's Brigade Combat Teams . The most numerous variant, the Infantry Brigade Combat Team, comprises light infantry battalions who fight on foot. Infantry Brigade Combat Teams of the 82nd Airborne Division are air assault capable, with infantry soldiers being transported by U.S. Army Aviation UH-60 Black Hawk and CH-47 Chinook helicopters. Infantry Brigade Combat Teams of

20672-453: The specific tasks and objectives of squadrons , companies , battalions , regiments , brigades , and divisions , and their naval and air force equivalents. One of the oldest military publications is The Art of War , by the Chinese philosopher Sun Tzu . Written in the 6th century BCE, the 13-chapter book is intended as military instruction, and not as military theory , but has had

20824-698: The system chosen by the state. Most military personnel are males; the minority proportion of female personnel varies internationally (approximately 3% in India, 10% in the UK, 13% in Sweden, 16% in the US, and 27% in South Africa ). While two-thirds of states now recruit or conscript only adults, as of 2017 50 states still relied partly on children under the age of 18 (usually aged 16 or 17) to staff their armed forces. Whereas recruits who join as officers tend to be upwardly-mobile , most enlisted personnel have

20976-471: The time of the Napoleonic Wars , military began to be used in reference to armed forces as a whole, such as " military service ", " military intelligence ", and " military history ". As such, it now connotes any activity performed by armed force personnel. Military history is often considered to be the history of all conflicts, not just the history of the state militaries. It differs somewhat from

21128-425: The two most distinctive features of a modern aircraft carrier: a full-length flight deck and a starboard-side control tower island . Both continued to be adjusted in the light of further experimentation and experience, however: Hōshō even opted to remove its island entirely in favor of a less obstructed flight deck and improved pilot visibility. Instead, Japanese carriers opted to control their flight operations from

21280-462: The wake of the Tampico Affair . In January 1912, the British battleship HMS  Africa took part in aircraft experiments at Sheerness . She was fitted for flying off aircraft with a 100-foot (30 m) downward-sloping runway which was installed on her foredeck, running over her forward 12-inch (305 mm) gun turret from her forebridge to her bow and equipped with rails to guide

21432-566: The word "military" in English, spelled militarie , was in 1582. It comes from the Latin militaris (from Latin miles ' soldier ' ) through French, but is of uncertain etymology, one suggestion being derived from *mil-it- – going in a body or mass. As a noun phrase, "the military" usually refers generally to a country's armed forces, or sometimes, more specifically, to the senior officers who command them. In general, it refers to

21584-503: The world's largest air-transportable X-band radar. The Ground-Based Midcourse Defense is an anti-ballistic missile system operated by Army Space and Missile Defense Command to defend the United States homeland against an intercontinental ballistic missile attack. Major Air Defense Artillery units include the 32nd Army Air and Missile Defense Command and Army Space and Missile Defense Command's 100th Missile Defense Brigade . Air Defense Artillery has an extremely close relationship with

21736-476: Was a need for widespread use of aircraft which could not be met quickly enough by building new fleet aircraft carriers. This was particularly true in the North Atlantic , where convoys were highly vulnerable to U-boat attack. The British authorities used unorthodox, temporary, but effective means of giving air protection such as CAM ships and merchant aircraft carriers , merchant ships modified to carry

21888-562: Was also not effective in war. World War II saw the emergence of naval aviation as the decisive element in the war at sea. The principal users were Japan, United States (both with Pacific interests to protect) and Britain. Germany, the Soviet Union, France and Italy had a lesser involvement. Soviet Naval Aviation was mostly organised as land-based coastal defense force (apart from some scout floatplanes it consisted almost exclusively of land-based types also used by its air arms). During

22040-656: Was formed 1 September 1982 and was a major command of the United States Air Force. The U.S. Congressional Research Office annually publishes a List of Notable Deployments of U.S. Military Forces Overseas since 1798. Presidential command over the U.S. Armed Forces is established in Article II in the Constitution whereby the president is named as the " Commander in Chief of the Army and Navy of

22192-746: Was not a complete success, owing to sub-optimal weather conditions, including fog and low cloud, but the raid was able to conclusively demonstrate the feasibility of air-to-land strikes from a naval platform. Two German airships were destroyed at the Tøndern base on July 19, 1918, by seven Sopwith Camels launched from the carrier HMS  Furious . In August 1914 Germany operated 20 planes and one Zeppelin, another 15 planes were confiscated. They operated from bases in Germany and Flanders (Belgium). On 19 August 1918 several British torpedo boats were sunk by 10 German planes near Heligoland. These are considered as

22344-718: Was one of a triumvirate of ' arts ' or 'sciences' that governed the conduct of warfare, the others being: military tactics , the execution of plans and manoeuvring of forces in battle , and maintenance of an army. The meaning of military tactics has changed over time; from the deployment and manoeuvring of entire land armies on the fields of ancient battles, and galley fleets; to modern use of small unit ambushes , encirclements , bombardment attacks, frontal assaults , air assaults , hit-and-run tactics used mainly by guerrilla forces, and, in some cases, suicide attacks on land and at sea. Evolution of aerial warfare introduced its own air combat tactics . Often, military deception , in

22496-400: Was realized some tangible increase in military capability, such as through greater effectiveness of a sharper edge in defeating armour , or improved density of materials used in manufacture of weapons. Naval aviation Naval aviation units are typically projected to a position nearer the target by way of an aircraft carrier . Carrier-based aircraft must be sturdy enough to withstand

22648-471: Was seen as largely impractical at the time. CAPT Washington Irving Chambers felt it was much easier to defend against airplanes than mines or torpedoes. The wireless radio was cumbersome (greater than 50 pounds), but the technology was improving.
