A-7 Corsair II

The A-7 Corsair II was a US carrier-based attack jet aircraft which was used by the US Navy during the Vietnam War. Although the A-7 was initially manufactured for the US Navy as a replacement of the Douglas A-4 Skyhawk, later it was also deployed by the US Air Force to replace the A-1 Skyraider and the F-100 Super Sabre. The Corsair II was developed by the American firm Ling-Temco-Vought (LTV). The prototype YA-7A made its first flight on September 26, 1965, entering into service with the United States Navy in February 1967.

The design of the LTV A-7 Corsair II was based on the F-8 Crusader fighter. It had a similar configuration, but was shorter and more stubby, with a rounded nose. The wing had a longer span, and the unique variable incidence wing of the F-8 was omitted. To achieve the required range, the A-7 was powered by a Pratt & Whitney TF30-P-6 turbofan producing 11,345 lbf of thrust. Pilots of the early A-7s lauded the aircraft for general ease of flying (with the exceptions of poor stability on cross-wind landings and miserable stopping performance on wet runways with an inoperative anti-skid braking system) and excellent forward visibility but noted a lack of engine thrust.

The first US Navy A-7A attack aircraft were deployed to Vietnam in 1967 with VA-147 Argonauts aboard USS Ranger. The aircraft made their first combat sortie on December 4, 1967. In the following months, VA-147 flew around 1,400 sorties losing only one aircraft. The US Air Force A-7Ds were also extensively used in Vietnam and Cambodia with 354th Tactical Fighter Wing, and the 388th Tactical Fighter Wing, flying from Korat RTAFB, Thailand. A-7s from the 354th TFW entered action in October 1972 and attacked targets as far as 800 km from airbases, extensively utilizing mid-air refueling. Variants: A-7A, A-7B, A-7C, TA-7C (two-seat trainer version), A-7D, A-7E, A-7G.
