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 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$1.66 billion in 2020).[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]

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.

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.

Die USS United States (CVA-58) sollte ein Flugzeugträger im Dienst der United States Navy werden. Das Schiff war als Typschiff der vier Schiffe umfassenden United-States-Klasse vorgesehen. Der Bau des Schiffes, das der erste „Supercarrier“ geworden wäre (also ein Flugzeugträger, der die Flugzeugträger des Zweiten Weltkrieges in seiner Größe weit übertreffen sollte), begann am 18. April 1949, wurde aber nur fünf Tage später wegen militärpolitischer Differenzen abgebrochen. Diese Entscheidung führte letztlich zum sogenannten „Aufstand der Admirale“.

L’USS United States (CVA-58) était le premier d'une série de cinq super porte-avions de la marine américaine qui devait être lancée à la fin des années 1940, au début de la Guerre froide, mais sa construction fut arrêté et le programme annulé. Il aurait été le troisième navire de l'US Navy à porter ce nom.

La USS United States (CVA-58) avrebbe dovuto essere la prima di una nuova classe di portaerei con funzioni di attacco nucleare nella complessa situazione strategica dei primi anni della Guerra Fredda. Progettata per alcuni anni[3], fino alla posa della chiglia nel 1949, sarebbe stata la prima superportaerei della storia con una lunghezza di 332 metri e un dislocamento di 65.000 tonnellate.

Юнайтед Стейтс (англ. United States, Соединённые Штаты) — американский послевоенный проект принципиально нового авианосца, предназначенного для атомных бомбардировок вероятного противника. В соответствии с Актом о военно-морских ассигнованиях 1949 года, одобренным Трумэном 28 июля 1948 года, были выделены средства на строительство пяти таких авианосцев. Закладка головного авианосца состоялась 18 апреля 1949 года на верфи Ньюпорт-Ньюз, однако через 5 дней строительство было прекращено, остальные четыре корабля не закладывались[1].
