――After World War II, jetting of carrier-capable fighter planes proceeded smoothly, but jetting of small carrier-capable attack aircraft was delayed, and even after the end of the Korean War, the A-1 Skyraider, a reciprocal aircraft, was the main force.
――The US Navy was fully aware of the importance of ground attacks in the Korean War, but the development of carrier-capable attack aircraft was delayed again due to the development of a fighter aircraft superior to the Communist Army's MiG15.
――However, in the early 1950s, the U.S. Navy embarked on a development plan for the next carrier-capable attack aircraft, and the Douglas design team responded to this plan with a total weight of 6.8 tons and a total width of less than 8.4 m, which was born from research on lightweight fighters. I proposed a machine.
――This drastic design proposal was approved and a contract was signed, and the prototype No. 1 (XA-4A), which flew for the first time on June 22, 1954, was thoroughly reduced in weight, and the main wings were integrated into the left and right to attach the fuselage to it. The aircraft was designed with consideration for simplification of the structure of the aircraft to be mounted and ease of maintenance.
――Until the delivery of the final mass-produced aircraft was completed in February 1979, the production period was 26 years and the total number of mass-produced aircraft was 2,960, demonstrating how excellent the basic design of the A-4 Skyhawk was.
--The A-4E is an improved version of the A-4C with the engine changed from J65 to J52-P-6. The shape of the air intake changes with the engine replacement, and the maximum armament load on the underside of the main wing is 8,200 lb. It was increased to (3,720 kg).
――The A-4F is the last type for the US Navy, and the engine has been powered up to the J52-P-8A, and a hump fairing for accommodating electronic devices has been added to the back of the fuselage.
――The A-4F was also used by the US Navy's aerobatics team `Blue Angels` from 1974 to 1986, and attracted the audience with its dynamic flight.
