Escort carrier HMS Audacity

The escort carrier or escort aircraft carrier (US hull classification symbol CVE), also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slow type of aircraft carrier used by the Royal Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers. While they were slower, carried fewer planes and were less well armed and armored, escort carriers were cheaper and could be built quickly, which was their principal advantage. Escort carriers could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable and several were sunk with great loss of life. The light carrier (hull classification symbol CVL) was a similar concept to escort carriers in most respects, but were capable of higher speeds to allow operation alongside fleet carriers.

The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.

United States Navy Naval warfare branch of the United States Armed Forces

The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U.S. allies or partner nations. with the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, and two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the Navy is the third largest of the service branches. It has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the second-largest air force in the world, after the United States Air Force.

Royal Navy Maritime warfare branch of the United Kingdoms military

The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the Kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service.

Most often built on a commercial ship hull, escort carriers were too slow to keep up with the main forces consisting of fleet carriers, battleships, and cruisers. Instead, they were used to escort convoys, defending them from enemy threats such as submarines and planes. In the invasions of mainland Europe and Pacific islands, escort carriers provided air support to ground forces during amphibious operations. Escort carriers also served as backup aircraft transports for fleet carriers and ferried aircraft of all military services to points of delivery.

Convoy group of vehicles traveling together for mutual support and protection

A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support. It may also be used in a non-military sense, for example when driving through remote areas. Arriving at the scene of a major emergency with a well-ordered unit and intact command structure can be another motivation.

In the Battle of the Atlantic, escort carriers were used to protect convoys against U-boats. Initially escort carriers accompanied the merchant ships and helped to fend off attacks from aircraft and submarines. As numbers increased later in the war, escort carriers also formed part of hunter-killer groups that sought out submarines instead of being attached to a particular convoy.

Battle of the Atlantic longest continuous military campaign in World War II

The Battle of the Atlantic was the longest continuous military campaign in World War II, running from 1939 to the defeat of Nazi Germany in 1945, and was a major part of the Naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. It was at its height from mid-1940 through to the end of 1943.

U-boat German submarine of the First or Second World War

U-boat is an anglicised version of the German word U-Boot[ˈuːboːt](listen), a shortening of Unterseeboot, literally "underseaboat." While the German term refers to any submarine, the English one refers specifically to military submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States to the United Kingdom and to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on the Axis powers in 1944.

In the Pacific theater, CVEs provided air support of ground troops in the Battle of Leyte Gulf. They lacked the speed and weapons to counter enemy fleets, relying on the protection of a Fast Carrier Task Force. However, at the Battle off Samar, one U.S. task force of escort carriers managed to successfully defend itself against a much larger Japanese force of battleships and cruisers. The Japanese met a furious defense of carrier aircraft, screening destroyers, and destroyer escorts, proving that CVEs could appear to have the same striking power as full CVs.

Battle of Leyte Gulf the largest naval battle of World War II

The Battle of Leyte Gulf is considered to have been the largest naval battle of World War II and, by some criteria, possibly the largest naval battle in history, with over 200,000 naval personnel involved. It was fought in waters near the Philippine islands of Leyte, Samar, and Luzon, from 23–26 October 1944, between combined American and Australian forces and the Imperial Japanese Navy (IJN), as part of the invasion of Leyte, which aimed to isolate Japan from the countries it had occupied in Southeast Asia which were a vital source of industrial and oil supplies.

Fast Carrier Task Force

The Fast Carrier Task Force was the main striking force of the United States Navy in the Pacific War from January 1944 through the end of the war in August 1945. The task force was made up of several separate task groups, each typically built around three to four aircraft carriers and their supporting vessels. The support vessels were screening destroyers, cruisers, and the newly built fast battleships.

Battle off Samar American ships make a last stand against many more Japanese ships; part of the Battle of Leyte Gulf

The Battle off Samar was the centermost action of the Battle of Leyte Gulf, one of the largest naval battles in history, which took place in the Philippine Sea off Samar Island, in the Philippines on October 25, 1944. It was the only major action in the larger battle where the Americans were largely unprepared against the opposing forces. The Battle off Samar has been cited by historians as one of the greatest last stands in naval history.

Of the 151 aircraft carriers built in the U.S. during World War II, 122 were escort carriers. Though no examples survive to this day, the Casablancaclass was the most numerous class of aircraft carrier, with 50 launched. Second was the Bogueclass, with 45 launched.

<i>Casablanca</i>-class escort carrier ship class

The Casablanca-class escort carriers were the most numerous class of aircraft carriers ever built. Fifty were laid down, launched and commissioned within the space of less than two years – 3 November 1942 through to 8 July 1944. These were nearly one third of the 151 carriers built in the United States during the war. Despite their numbers, and the preservation of more famous and larger carriers as museums, none of these modest ships survive today. Five were lost to enemy action during World War II and the remainder were scrapped.

<i>Bogue</i>-class escort carrier ship class

The Bogue class were a class of escort carriers built in the United States for service with the U.S. Navy and the Royal Navy during World War II. Following the war, ten Bogue-class ships were kept in service by the U.S. Navy and were used for helicopter and aircraft transport operations.

Development

In the early 1920s, the Washington Naval Treaty imposed limits on the maximum size and total tonnage of aircraft carriers for the five main naval powers. Later treaties largely kept these provisions. As a result, construction between the World Wars had been insufficient to meet operational needs for aircraft carriers as World War II expanded from Europe. Too few fleet carriers were available to simultaneously transport aircraft to distant bases, support amphibious invasions, offer carrier landing training for replacement pilots, conduct anti-submarine patrols, and provide defensive air cover for deployed battleships and cruisers. The foregoing mission requirements limited use of fleet carriers′ unique offensive strike capability demonstrated at the Battle of Taranto and the Attack on Pearl Harbor. Conversion of existing ships (and hulls under construction for other purposes) provided additional aircraft carriers until new construction became available.

Washington Naval Treaty treaty among the major nations that had won World War I

The Washington Naval Treaty, also known as the Five-Power Treaty, was a treaty signed during 1922 among the major nations that had won World War I, which agreed to prevent an arms race by limiting naval construction. It was negotiated at the Washington Naval Conference, held in Washington, D.C., from November 1921 to February 1922, and it was signed by the governments of the United Kingdom, the United States, France, Italy, and Japan. It limited the construction of battleships, battlecruisers and aircraft carriers by the signatories. The numbers of other categories of warships, including cruisers, destroyers and submarines, were not limited by the treaty, but those ships were limited to 10,000 tons displacement each.

Battle of Taranto battle

The Battle of Taranto took place on the night of 11–12 November 1940 during the Second World War between British naval forces, under Admiral Andrew Cunningham, and Italian naval forces, under Admiral Inigo Campioni. The Royal Navy launched the first all-aircraft ship-to-ship naval attack in history, employing 21 obsolete Fairey Swordfish biplane torpedo bombers from the aircraft carrier HMS Illustrious in the Mediterranean Sea. The attack struck the battle fleet of the Regia Marina at anchor in the harbour of Taranto, using aerial torpedoes despite the shallowness of the water. The success of this attack augured the ascendancy of naval aviation over the big guns of battleships. According to Admiral Cunningham, "Taranto, and the night of 11–12 November 1940, should be remembered for ever as having shown once and for all that in the Fleet Air Arm the Navy has its most devastating weapon."

Attack on Pearl Harbor Surprise attack by the Imperial Japanese Navy on the U.S. Pacific Fleet in Pearl Harbor in Hawaii

The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Hawaii on Sunday morning, December 7, 1941. The attack led to the United States' formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.

Conversions of cruisers and passenger liners with speed similar to fleet carriers were identified by the U.S. as "light aircraft carriers" (hull classification symbol CVL) able to operate at battle fleet speeds. Slower conversions were classified as "escort carriers" and were considered naval auxiliaries suitable for pilot training and transport of aircraft to distant bases.

The Royal Navy had recognized a need for carriers to defend its trade routes in the 1930s. [1] While designs had been prepared for "trade protection carriers" and five suitable liners identified for conversion, nothing further was done mostly because there were insufficient aircraft for even the fleet carriers under construction at the time. However, by 1940 the need had become urgent and HMS Audacity was converted from the captured German merchant ship MV Hannover and commissioned in July 1941. [2] For defense from German aircraft, convoys were supplied first with fighter catapult ships and CAM ships that could carry a single (disposable) fighter. In the interim, before escort carriers could be supplied, they also brought in merchant aircraft carriers that could operate four aircraft.

In 1940, Admiral William Halsey recommended construction of naval auxiliaries for pilot training. [3] In early 1941 the British asked the US to build on their behalf six carriers of an improved Audacity design but the US had already begun their own escort carrier. [4] On 1 February 1941, the United States Chief of Naval Operations gave priority to construction of naval auxiliaries for aircraft transport. [5] U.S. ships built to meet these needs were initially referred to as auxiliary aircraft escort vessels (AVG) in February 1942 and then auxiliary aircraft carrier (ACV) on 5 August 1942. [6] The first U.S. example of the type was USS Long Island. Operation Torch and North Atlantic anti-submarine warfare proved these ships capable aircraft carriers for ship formations moving at the speed of trade or amphibious invasion convoys. U.S. classification revision to escort aircraft carrier (CVE) on 15 July 1943 reflected upgraded status from auxiliary to combatant. [7] They were informally known as "Jeep carriers" or "baby flattops". It was quickly found that the escort carriers had better performance than light carriers, which tended to pitch badly in moderate to high seas. The Commencement Bay class was designed to incorporate the best features of American CVLs on a more stable hull with a less expensive propulsion system. [8]

Among their crews, CVE was sarcastically said to stand for "Combustible, Vulnerable, and Expendable". Magazine protection was minimal in comparison to fleet aircraft carriers. [9] HMS Avenger was sunk within minutes by a single torpedo, and HMS Dasher exploded from undetermined causes with very heavy loss of life. Three escort carriers—USS St. Lo, Ommaney Bay and Bismarck Sea—were destroyed by kamikazes , the largest ships to meet such a fate.

Allied escort carriers were typically around 500 ft (150 m) long, not much more than half the length of the almost 900 ft (270 m) fleet carriers of the same era, but were less than 1/3 of the weight. A typical escort carrier displaced about 8,000 long ton s (8,100  t ), as compared to almost 30,000 long tons (30,000 t) for a full-size fleet carrier. The aircraft hangar typically ran only 1/3 of the way under the flight deck and housed a combination of 24–30 fighters and bombers organized into one single "composite squadron". By comparison, a late Essex-class fleet carrier could carry a total of 103 aircraft organized into separate fighter, bomber and torpedo-bomber squadrons.

The island on these ships was small and cramped, and located well forward of the funnels (unlike on a normal-sized carrier where the funnels were integrated into the island). Although the first escort carriers had only one aircraft elevator, having two elevators (one fore and one aft), along with the single aircraft catapult, quickly became standard. The carriers employed the same system of arresting cables and tail hooks as on the big carriers, and procedures for launch and recovery were the same as well.

The crew size was less than 13 of that of a large carrier, but this was still a bigger complement than most naval vessels. It was large enough to justify the existence of facilities such as a permanent canteen or snack bar, called a gedunk bar, in addition to the mess. The bar was open for longer hours than the mess and sold several flavors of ice cream, along with cigarettes and other consumables. There were also several vending machines available on board.

In all, 130 Allied escort carriers were launched or converted during the war. Of these, six were British conversions of merchant ships: HMS Audacity, Nairana, Campania, Activity, Pretoria Castle and Vindex. The remaining escort carriers were U.S.-built. Like the British, the first U.S. escort carriers were converted merchant vessels (or in the Sangamonclass, converted military oilers). The Bogue-class carriers were based on the hull of the Type C3 cargo ship. The last 69 escort carriers of the Casablanca and Commencement Bay classes were purpose-designed and purpose-built carriers drawing on the experience gained with the previous classes.

Royal Navy

Originally developed at the behest of the United Kingdom to operate as part of a North Atlantic convoy escort, rather than as part of a naval strike force, many of the escort carriers produced were assigned to the Royal Navy for the duration of the war under the Lend-Lease act. They supplemented and then replaced the converted merchant aircraft carriers that were put into service by the British and Dutch as an emergency measure until the escort carriers became available. As convoy escorts, they were used by the Royal Navy to provide air scouting, to ward off enemy long-range scouting aircraft and, increasingly, to spot and hunt submarines. Often additional escort carriers also joined convoys, not as fighting ships, but as transporters, ferrying aircraft from the U.S. to Britain. In this case, the aircraft cargo could be doubled by storing aircraft on the flight deck as well as in the hangar.

The ships sent to the Royal Navy were slightly modified, partly to suit the traditions of that service. Among other things the ice cream making machines were removed, since they were considered unnecessary luxuries on ships, which served grog and other alcoholic beverages. The heavy duty washing machines of the laundry room were also removed since "all a British sailor needs to keep clean is a bucket and a bar of soap" (quoted from Warrilow).

Other modifications were due to the need for a completely enclosed hangar when operating in the North Atlantic and in support of the Arctic convoys.

U.S. Navy service

Meanwhile, the U.S. discovered their own use for the escort carriers. In the North Atlantic, they supplemented the escorting destroyers by providing air support for anti-submarine warfare. One of these escort carriers, USS Guadalcanal, was instrumental in the capture of U-505 off North Africa in 1944.

In the Pacific theater, escort carriers lacked the speed to sail with fast carrier attack groups, so were often tasked to escort the landing ships and troop carriers during the island-hopping campaign. In this role they provided air cover for the troopships and flew the first wave of attacks on beach fortifications in amphibious landing operations. On occasion, they even escorted the large carriers, serving as emergency airstrips and providing fighter cover for their larger sisters while these were busy readying or refueling their own planes. They also transported aircraft and spare parts from the U.S. to remote island airstrips.

The attack on Pearl Harbor brought up an urgent need for aircraft carriers, so some T3 tankers were converted to escort carriers, USS Suwannee is example of how a T3 tanker hull AO-33 was rebuilt to be an escort carrier. The T3 tanker size and speed made the T3 a useful escort carrier. There were two classes of T3 hull carriers: Sangamon class and Commencement Bay class. [10] [11] [12]

A major battle for these escort carriers was the Battle off Samar in the Philippines on 25 October 1944. The Japanese lured Admiral William Halsey, Jr. into chasing a decoy fleet with his 3rd Fleet. This left aircraft from 16 small and slow escort carriers in three task groups armed primarily to bomb ground forces; along with their protective screen of destroyers and slower destroyer escorts, with "Taffy 3" bearing the brunt of the fight. They faced a Japanese force of four battleships, including the formidable [13] Yamato, eight cruisers, and 11 destroyers. The American ships held off the Japanese.

The slow carriers could not outrun 30 kn (35 mph; 56 km/h) cruisers. They launched their aircraft and maneuvered to avoid shellfire for over an hour. They took dozens of hits, mostly from armor-piercing rounds that passed right through their thin, unarmored hulls without exploding. USS Gambier Bay, sunk in this action, was the only U.S. carrier lost to enemy surface gunfire in the war, and the Japanese concentration of fire on this one carrier assisted the escape of the others. The carriers′ only substantial armament—aside from their aircraft—was a single 5 in (127 mm) dual-purpose gun mounted on the stern, but the pursuing Japanese cruisers closed to within range of these guns. One of the guns caused critical damage to the burning Japanese heavy cruiser Chōkai and a subsequent bomb dropped from one of the task force′s aircraft hit the heavy cruiser′s forward machinery room, leaving her dead in the water. Several kamikaze aircraft were shot down by carrier gunners, with only USS St Lo lost to air attack. The Americans lost a similar number of ships and men to the Battle of Coral Sea and Battle of Midway combined.

The ships

Many escort carriers were Lend-Leased to the United Kingdom, this list specifies the breakdown in service to each navy.

In addition, six escort carriers were produced by the British during the war (all converted from other vessels).

The table below lists escort carriers and similar ships performing the same missions. The first four were built as early fleet aircraft carriers. Merchant aircraft carriers (MAC) carried trade cargo in addition to operating aircraft. Aircraft transports carried larger numbers of planes by eliminating accommodation for operating personnel and storage of fuel and ammunition.

Post-World War II

The years following World War II brought many revolutionary new technologies to the navy, most notably the helicopter and the jet fighter, and with this a complete rethinking of its strategies and ships′ tasks. Although several of the latest Commencement Bay-class CVE were deployed as floating airfields during the Korean War, the main reasons for the development of the escort carrier had disappeared or could be dealt with better by newer weapons. The emergence of the helicopter meant that helicopter-deck equipped frigates could now take over the CVE's role in a convoy while also performing their own traditional role as submarine hunters. Ship-mounted guided missile launchers took over much of the aircraft protection role, and in-flight refueling abolished the need for floating stopover points for transport or patrol aircraft. As a result, after the Commencement Bay class, no new escort carriers were designed, and with every downsizing of the navy, the CVEs were the first to be mothballed.

Several escort carriers were pressed back into service during the first years of the Vietnam War because of their ability to carry large numbers of aircraft. Redesignated AKV (air transport auxiliary), they were manned by a civilian crew and used to ferry whole aircraft and spare parts from the U.S. to Army, Air Force and Marine bases in South Vietnam. However, CVEs were useful in this role only for a limited period. Once all major aircraft were equipped with refueling probes, it became much easier to fly the aircraft directly to its base instead of shipping it overseas.

The last chapter in the history of escort carriers consisted of two conversions: As an experiment, USS Thetis Bay was converted from an aircraft carrier into a pure helicopter carrier (CVHA-1) and used by the Marine Corps to carry assault helicopters for the first wave of amphibious warfare operations. Later, Thetis Bay became a full amphibious assault ship (LHP-6). Although in service only from 1955 (the year of her conversion) to 1964, the experience gained in her training exercises greatly influenced the design of today′s amphibious assault ships.

In the second conversion, in 1961, USS Gilbert Islands had all her aircraft handling equipment removed and four tall radio antennas installed on her long, flat deck. In lieu of aircraft, the hangar deck now had no fewer than 24 military radio transmitter trucks bolted to its floor. Rechristened USS Annapolis, the ship was used as a communication relay ship and served dutifully through the Vietnam War as a floating radio station, relaying transmissions between the forces on the ground and the command centers back home. Like Thetis Bay, the experience gained before Annapolis was stricken in 1976 helped develop today′s purpose-built amphibious command ships of the Blue Ridgeclass.

Unlike almost all other major classes of ships and patrol boats from World War II, most of which can be found in a museum or port, no escort carrier or American light carrier has survived: all were destroyed during the war or broken up in the following decades. The Dictionary of American Naval Fighting Ships records that the last former escort carrier remaining in naval service — USS Annapolis (ex- USS Gilbert Islands) — was sold for scrapping 19 December 1979. The last American light carrier (the escort carrier′s faster sister type) was USS Cabot, which was broken up in 2002 after a decade-long attempt to preserve the vessel.

The U.S. designed the Sea Control Ship [18] to serve a similar role; whilst none were actually built, the Spanish Principe de Asturias and the Thai Chakri Naruebet are based on the concept.

USS Langley (CV-1/AV-3) was the United States Navy's first aircraft carrier, converted in 1920 from the collier USS Jupiter (AC-3), and also the US Navy's first turbo-electric-powered ship. Conversion of another collier was planned but canceled when the Washington Naval Treaty required the cancellation of the partially built Lexington-class battlecruisers Lexington and Saratoga, freeing up their hulls for conversion to the aircraft carriers Lexington and Saratoga. Langley was named after Samuel Pierpont Langley, an American aviation pioneer. Following another conversion to a seaplane tender, Langley fought in World War II. On 27 February 1942, she was attacked by nine twin-engine Japanese bombers of the Japanese 21st and 23rd Naval Air Flotillas and so badly damaged that she had to be scuttled by her escorts.

Light aircraft carrier aircraft carrier that is smaller than the standard carriers of a navy

A light aircraft carrier, or light fleet carrier, is an aircraft carrier that is smaller than the standard carriers of a navy. The precise definition of the type varies by country; light carriers typically have a complement of aircraft only one-half to two-thirds the size of a full-sized fleet carrier. A light carrier was similar in concept to an escort carrier in most respects, however light carriers were intended for higher speeds to be deployed alongside fleet carriers, while escort carriers usually defended convoys and provided air support during amphibious operations.

The Independence-class aircraft carriers were a class of light carriers built for the United States Navy that served during World War II.

HMAS <i>Hobart</i> (D63) 1936-1962 modified Leander-class light cruiser of the Royal and Royal Australian Navies

HMAS Hobart was a modified Leander-class light cruiser which served in the Royal Australian Navy (RAN) during World War II. Originally constructed for the Royal Navy as HMS Apollo, the ship entered service in 1936, and was sold to Australia two years later. During the war, Hobart was involved in the evacuation of British Somaliland in 1940, fought at the Battle of the Coral Sea and supported the amphibious landings at Guadalcanal and Tulagi in 1942. She was torpedoed by a Japanese submarine in 1943, then returned to service in 1945 and supported the landings at Tarakan, Wewak, Brunei, and Balikpapan. Hobart was placed in reserve in 1947, but plans to modernise her and return her to service as an aircraft carrier escort, training ship, or guided missile ship were not followed through. The cruiser was sold for scrapping in 1962.

The names of commissioned ships of the United States Navy all start with USS, for "United States Ship". Non-commissioned, primarily civilian-manned vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for "United States Naval Ship". A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals. Usually, different types of ships have names originated from different types of sources.

Escort destroyer ship type

An escort destroyer with United States Navy hull classification symbol DDE was a destroyer (DD) modified for and assigned to a fleet escort role after World War II. These destroyers retained their original hull numbers. Later, in March 1950, the post World War II ASW destroyer (DDK) classification was merged with the DDE classification, resulting in all DDK ships being reclassified as DDE, but again retaining their original hull numbers. On 30 June 1962, the DDE classification was retired, and all DDEs were reclassified as destroyers (DD). Escort destroyers should not be confused with the cheaper, slower, less capable, and more lightly armed World War II destroyer escorts.

<i>Commencement Bay</i>-class escort carrier ship class

The Commencement Bay-class escort aircraft carriers were the last class of escort carriers built for the US Navy in World War II.

A radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a force to protect it from surprise attack, typically air attack. Radar picket vessels may also be equipped to direct friendly fighters to intercept the enemy. In British terminology the radar picket function is called aircraft direction. Often several detached radar units encircle a force to provide increased cover in all directions. Airborne radar pickets are generally referred to as airborne early warning.

Amphibious assault ship Type of warship used in amphibious assaults

An amphibious assault ship is a type of amphibious warfare ship employed to land and support ground forces on enemy territory by an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers. Modern ships support amphibious landing craft, with most designs including a well deck. Coming full circle, some amphibious assault ships also support V/STOL fixed-wing aircraft, now having a secondary role as aircraft carriers.

History of the aircraft carrier aspect of history

Aircraft carriers are warships that evolved from balloon-carrying wooden vessels into nuclear-powered vessels carrying scores of fixed- and rotary-wing aircraft. Since their introduction they have allowed naval forces to project air power great distances without having to depend on local bases for staging aircraft operations.
