About A-7 Corsair II
A-7 Corsair II Military Aircraft, photo wallpapers: The Ling-Temco-Vought A-7 Corsair II was a light attack aircraft based on the F-8 Crusader. The A-7 was one of the first combat aircraft to feature a heads up display (HUD), doppler-bounded inertial navigation system, and a turbofan engine. It served with both the United States Navy and the United States Air Force, and later with the Air National Guard. It was also exported to Greece (in the 1970s), Portugal and Thailand (in the late 1980s).
In 1962, USN began preliminary work on VAX (Heavier-than-air, Attack, Experimental), a replacement for the A-4 Skyhawk with greater range and payload. A particular emphasis was placed on accurate delivery of weapons to reduce the cost per target. The requirements were finalized in 1963 and in 1964 the Navy announced the VAL (Heavier-than-air, Attack, Light) competition. Since the upcoming General Dynamics F-111B was supposed to fulfill the advanced strike role, the NAL was intended to be only an interim solution. To minimize costs, all proposals had to be based on existing designs. Vought, Douglas Aircraft, Grumman, and North American Aviation responded. The Vought proposal was selected as the winner on 11 February 1964, and on 19 March the company received a contract for the initial batch of aircraft, designated A-7. In 1965 the aircraft received the popular name Corsair II, after Vought's highly successful F4U Corsair of World War Two. The A-7 was based on the F-8 Crusader fighter but had a shorter, broader fuseage, and a larger wing. The Crusader's variable incidence wing was deleted. To achieve the required range, A-7 was powered by a Pratt & Whitney TF-30-Р-6 turbofan shared with the F-111 producing 11,345 lbf (50.5 kN) of thrust. Since supersonic performance was not required, the engine was not fitted with an afterburner. The aircraft was fitted with an AN/APQ-116 radar integrated into the ILAAS digital navigation and weapons computer. It was one of the fir...
