USS United States (CVA-58) was to be the lead ship of a new design of aircraft carrier. On 29 July 1948, President Harry Truman approved construction of five "supercarriers", for which funds had been provided in the Naval Appropriations Act of 1949. The keel of the first of the five planned postwar carriers was laid down on 18 April 1949 at Newport News Drydock and Shipbuilding.^[2] The program was canceled in 1949, United States was not completed, and the other four planned carriers were never built.

Design

The chief proponent for the new large carrier was Admiral Marc Mitscher.^[6] He wanted a carrier that would be able to handle the most effective weapons of the day. Early design discussions centered around developing a carrier that would be able to support combat missions using the new jet aircraft. These were faster, larger and significantly heavier than the aircraft which the Essex- and Midway-class carriers were handling at the end of the Second World War. It was thought that the aircraft carried would have to have longer range to allow the carrier to operate farther away from the target. The deck would have to be able to handle the weight of the heavy jet aircraft landing on the deck. The implication was that the ship's strength deck would have to be the flight deck rather than the hangar deck, as had been the case for earlier U.S. carriers.^[7] Armoring the flight deck would mean the ship would have a greater tendency to roll in rough seas, as a greater part of the ship's weight would be high above the waterline.

Based on the size of the aircraft that the new ship was to carry, the design of the carrier was to be flush decked, meaning that the ship would have no island control structure. This would be done to create more space for large winged aircraft.^[8] The flush-deck design carried with it two major concerns. The first concern was over how smoke from the power plants would be diverted from the flight deck.^[9] This had been a major issue with the US Navy's first aircraft carrier, USS Langley, in the 1920s when carrier development was first underway. The second concern was the placement of early warning radar equipment to allow the ship to detect incoming attacks. One solution was for a command ship to be close by which would carry the commander of the task force and the early detection radar. The command ship would radio electronic information and orders from its command center over to the carrier. This command ship role was termed a 'pilotfish' and the USS Northampton (CLC-1) would be built in part to fulfill this role.^[10] A second solution was for the ship to carry aircraft that could fly the early warning radar. These would fly overhead and detect approaching aircraft.^[8] In truth, the ship as designed would not be able to safely operate by itself, but would need to operate in conjunction with traditional fleet carriers as a complementary bomber-carrier. In fact, the ship was being designed on the basis of the aircraft that it was thought it would carry, and these were based on projections of what aircraft would be in existence in the period 1952 to 1960.^[8]

Discussions included debate on the aircraft carrier's mission. One view was that it would carry a group of large bombers that would be secured to the flight deck, with no hangar for these aircraft, as they would be too large to move up and down in an elevator.^[11] Though they would be built to carry large nuclear weapons, the total amount of space used for munition storage would be reduced as multiple strikes would not be likely. A small hangar deck would be available for a limited fighter escort and a small magazine for a small number of heavy nuclear weapons. Another plan was that it could be built with conventional attack capability with a large hangar deck for a large air wing and a large magazine.^[12] The nuclear attack supporters won in the initial design stage, but the design was modified to carry more fighters. The flush-deck United States was designed to launch and recover the 100,000 pound (45 t) aircraft required to carry early-model nuclear weapons, which weighed as much as five tons.^[4] The ship would have no permanently raised island or command tower structure.^[8] It would be equipped with four aircraft elevators located at the deck edges to avoid decreasing the structural strength of the flight deck. Four catapults would be used to launch aircraft, with two at the bow and two others on the outer edge of the deck staggered back. The carrier was designed so that it could land aircraft at the rear while at the same time launching aircraft from the catapults at the bow and forward area simultaneously.^[13] The construction cost of the new ship was estimated at US$189 million^[1] (equivalent to US$1.92 billion in 2023).^[14]

Proposed operations

USS United States was designed with the primary mission of carrying long-range bomber aircraft that could carry a heavy enough load to undertake nuclear bombardment missions. It would also carry long range escort fighters that would fly along and protect its bombers. The ship could also take on other roles, such as providing air support for amphibious forces and to conduct sea control operations, but it was primarily to be a "bomber carrier".^[15] It was thought it would operate in a task force coupled with traditional attack carriers, which would provide the air cover for the task force. That mission was virtually certain to make the ship a target of inter-service rivalries over missions and funding. The United States Air Force viewed United States as a challenge to their monopoly on strategic nuclear weapons delivery.^[1]

Keel laying; cancellation

Looking to cut the military budget and accepting without question the Air Force argument on nuclear deterrence by means of large, long-range bombers, Secretary of Defense Louis A. Johnson announced the cancellation of United States on 23 April 1949, five days after the ship's keel was laid.^[3] Secretary of the Navy John Sullivan immediately resigned, and Congress held an inquiry into the manner and wisdom of Johnson's decision. In the subsequent "Revolt of the Admirals", the Navy was unable to advance its case that large carriers would be essential to national defense.^[16]

Soon afterward, Johnson and Francis P. Matthews, the man he advanced to be the new Secretary of the Navy, set about punishing those officers that let their opposition be known.^[17] Navy Admiral Louis Denfeld was forced to resign as Chief of Naval Operations, and a number of other admirals and lesser ranks were punished. The invasion of South Korea six months later resulted in an immediate need for a strong naval presence, and Matthews' position as Secretary of the Navy and Johnson's position as Secretary of Defense crumbled, both ultimately resigning.^{[ citation needed ]}

Soon after she was canceled, the aircraft carrier's keel was dismantled. This freed up the drydock, allowing crews to immediately begin construction on the ocean liner SS United States (name coincidental).^[18]

The Navy soon found a means to carry nuclear weapons at sea, placed aboard the aircraft carrier USS Franklin D. Roosevelt in 1950.^[4] Thus the question of which service would have primary responsibility for strategic nuclear strikes was not answered with Johnson's cancellation of USS United States.^{[ citation needed ]}

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increases the time of availability on the combat zone.

The escort carrier or escort aircraft carrier, 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 slower type of aircraft carrier used by the Royal Navy, the Royal Canadian 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, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they 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 was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.

The Nimitz class is a class of ten nuclear-powered aircraft carriers in service with the United States Navy. The lead ship of the class is named after World War II United States Pacific Fleet commander Fleet Admiral Chester W. Nimitz, who was the last living U.S. Navy officer to hold the rank. With an overall length of 1,092 ft (333 m) and a full-load displacement of over 100,000 long tons (100,000 t), the Nimitz-class ships were the largest warships built and in service until USS Gerald R. Ford entered the fleet in 2017.

USS Enterprise (CVN-65), formerly CVA(N)-65, is a decommissioned United States Navy aircraft carrier. In 1958, she became the first nuclear-powered aircraft carrier in the United States Navy, and the eighth United States naval vessel to bear the name. Like her predecessor of World War II fame, she is nicknamed "Big E". At 1,123 feet (342 m), she is the longest naval vessel ever built and the only ship of a class that was originally planned to have five other ships. Her 93,284-long-ton (94,781 t) displacement ranks her class as the third largest carrier class, after the Nimitz class and the Gerald R. Ford class. Enterprise had a crew of some 4,600 service members.

USS Ranger (CV-4) was an interwar United States Navy aircraft carrier, the only ship of its class. As a Treaty ship, Ranger was the first U.S. vessel to be designed and built from the keel up as a carrier. She was relatively small, just 730 ft (222.5 m) long and under 15,000 long tons (15,000 t), closer in size and displacement to the first US carrier—Langley—than later ships. An island superstructure was not included in the original design, but was added after completion.

USS Hornet (CV-8), the seventh U.S. Navy vessel of that name, was a Yorktown-class aircraft carrier of the United States Navy.

USS Franklin, nicknamed "Big Ben," was one of 24 Essex-class aircraft carriers built during World War II for the United States Navy, and the fifth US Navy ship to bear the name. Commissioned in January 1944, she served in several campaigns in the Pacific War, earning four battle stars. In March 1945, while launching strikes against the Japanese mainland, she was badly damaged when a single Japanese dive bomber struck her with two bombs. The attack resulted in the loss of 807 of her crew and Franklin became the most heavily-damaged United States aircraft carrier to survive the war. The complement of Franklin suffered 924 killed in action during the war, the worst for any surviving U.S. warship and second only to that of USS Arizona.

The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships".

The Yorktown class was a class of three aircraft carriers built for the United States Navy and completed shortly before World War II, the Yorktown (CV-5), Enterprise (CV-6), and Hornet (CV-8). They immediately followed Ranger, the first U.S. aircraft carrier built as such, and benefited in design from experience with Ranger and the earlier Lexington class, which were conversions into carriers of two battlecruisers that were to be scrapped to comply with the Washington Naval Treaty, an arms limitation accord.

The Midway class was a class of three United States Navy aircraft carriers. The lead ship, USS Midway, was commissioned in September 1945 and decommissioned in 1992. USS Franklin D. Roosevelt was commissioned in October 1945, and taken out of service in 1977. USS Coral Sea was commissioned in April 1947, and decommissioned in 1990.

The Forrestal-class aircraft carriers were four aircraft carriers designed and built for the United States Navy in the 1950s. The class ship was named for James Forrestal, the first United States Secretary of Defense. It was the first class of supercarriers, combining high tonnage, deck-edge elevators and an angled deck. The first ship was commissioned in 1955, the last decommissioned in 1998. The four ships of the class were scrapped in Brownsville, Texas, between 2014 and 2017.

The Illustrious class was a class of aircraft carrier of the Royal Navy that included some of the most important British warships in the Second World War. They were laid down in the late 1930s as part of the rearmament of British forces in response to the emerging threats of Nazi Germany, Fascist Italy and Imperial Japan.

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

Taihō was an aircraft carrier of the Imperial Japanese Navy during World War II. Possessing heavy belt armor and featuring an armored flight deck, she represented a major departure from prior Japanese aircraft carrier design and was expected to not only survive multiple bomb, torpedo, or shell hits, but also continue fighting effectively afterwards.

The aircraft cruiser is a warship that combines the features of the aircraft carrier and a surface warship such as a cruiser or battleship.

An armoured flight deck is an aircraft carrier flight deck that incorporates substantial armour in its design.

1967 USS <i>Forrestal</i> fire Shipboard fire at sea

On 29 July 1967, a fire broke out on board the aircraft carrier USS Forrestal after an electrical anomaly caused a Zuni rocket on an F-4B Phantom to fire, striking an external fuel tank of an A-4 Skyhawk. The flammable jet fuel spilled across the flight deck, ignited, and triggered a chain reaction of explosions that killed 134 sailors and injured 161. At the time, Forrestal was engaged in combat operations in the Gulf of Tonkin, during the Vietnam War. The ship survived, but with damage exceeding US$72 million, not including the damage to aircraft. Future United States Senator John McCain and future four-star admiral and U.S. Pacific Fleet Commander Ronald J. Zlatoper were among the survivors. Another on-board officer, Lieutenant Tom Treanore, later returned to the ship as her commander and retired an admiral.

Aircraft carriers are warships that evolved from balloon-carrying wooden vessels into nuclear-powered vessels carrying many dozens 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.

The flight-deck cruiser was a proposed type of aircraft cruiser,, designed by the United States Navy during the Interwar period. Several designs were proposed for the type, but none was approved for construction. The final design was developed just before World War II, and the entry of the United States into the war saw the project come to an end.

The Essex class is a retired class of aircraft carriers of the United States Navy. The 20th century's most numerous class of capital ship, the class consisted of 24 vessels, which came in "short-hull" and "long-hull" versions. Thirty-two ships were ordered, but as World War II wound down, six were canceled before construction, and two were canceled after construction had begun. Fourteen saw combat during World War II. None were lost to enemy action, though several sustained crippling damage due to kamikaze attacks. Essex-class carriers were the backbone of the U.S. Navy from mid-1943 and, with the three Midway-class carriers added just after the war, continued to be the heart of U.S. naval strength until supercarriers joined the fleet in the 1950s, 1960s and 1970s. Several of the carriers were rebuilt to handle heavier and faster aircraft of the early jet age, and some served until well after the Vietnam War. Of the 24 ships in the class, four – Yorktown, Hornet, Lexington, and Intrepid – have been preserved as museum ships.
