De OPThe Skyhawk was designed by Douglas' Ed Heinemann in response to a U.S. Navy call for a jet-powered attack aircraft to replace the A-1 Skyraider. Heinemann opted for a design that would minimize size, weight, and complexity. The result was an aircraft that weighed only half of the Navy's specification and had a wing so compact that it did not need to be folded for carrier stowage. The diminutive Skyhawk soon received the nicknames "Scooter," "Bantam Bomber," and, on account of its nimble performance, "Heinemann's Hot-Rod."
The aircraft is of conventional post-WW2 design, with a low-mounted delta-like wing, tricycle undercarriage, and a single turbojet engine in the rear fuselage, with intakes on the fuselage sides. The tail is of cruciform design, with the horizontal stabilizer mounted above the fuselage. Armament consisted of two 20 mm Colt Mk 12 cannon, one in each wing root, with 200 rounds per gun, plus a large variety of bombs, rockets, and missiles carried on a hardpoint under the fuselage centreline and hardpoints under each wing (originally one per wing, later two).
The Navy issued a contract for the type on June 12 1952, and the first prototype first flew on June 22, 1954. Deliveries to Navy and U.S. Marine Corps squadrons commenced in late 1956.
The Skyhawk remained in production until 1975, with a total of 2,960 aircraft built, including 555 two-seat trainers. The US Navy began removing the aircraft from its front-line squadrons in 1967, with the last retiring in 1975. The last Marine Skyhawk was delivered in 1979, and were used until the mid-1990s. Trainer versions of the Skyhawk remained in Navy service, however, found a new lease on life with the advent of adversary training, where the nimble A-4 was used as a stand-in for the MiG-17 in dissimilar air combat training (DACT). It served in that role until 1999, when the last were replaced with the T-45 Goshawk. The last US Navy Skyhawks, TA-4J models belonging to composite squadron VC-8, remained in military use for target-towing and as adversary aircraft for combat training at Naval Air Station Roosevelt Roads. They were officially retired on May 3, 2003.
