The A-7 Corsair II was a light bomber and attack aircraft used primarily by the Navy. It was intended as a complement and eventually a replacement for the A-4 Skyhawk.
Contents
Design
The Navy wanted an aircraft with increased range and payload to replace the A-4. Several companies, including Grumman, Douglas, and North American tried for the contract, but eventually it was Vought who received the contract.
Vought built the aircraft in a remarkably short time, mostly because it was basically the same design as the F-8 Crusader. The first test aircraft (named after the World War II fighter) were delivered in 1964.
After a period of onshore testing, the A-7 was delivered to VA-147 on the USS Ranger in 1966. The Air Force also bought a more highly powered version for light ground support.
Versions
A-7B
The A-7Bs had the more powerful Pratt & Whitney TF30-P-8 engine, which provided 12,200 pounds of thrust. These airplanes were the primary A-7 version in Vietnam.
A-7C
The A-7Cs were modified to carry the 13,400 pounds of thrust Pratt & Whitney TF30-P-408 engine.
A-7D
The A-7Ds were the first to carry the M61A-1 Vulcan cannon in the fuselage. They also were equipped with laser-guided bombs.
A-7E
The A-7Es had an Allison/Rolls-Royce engine which provided 15,000 pounds of thrust. It also was equipped with forward looking infrared (FLIR) equipment which enabled it to fly at night.
Service
The A-7s combat debut came in Vietnam, where it was effective in attacks on North Vietnamese MiG bases and on the Ho Chi Minh Trail in Laos. One shining star on the career of the airplane came when six A-7s with Mark 55 mines, supported only by several F-4s and two EA-6 Prowlers, mined Haiphong Harbor in 1972. Despite doubts by some military leaders, the aircraft held its own against supersonic jets.
Corsairs saw combat again ten years later, in strikes on Syrian positions in Lebanon in December 1983.[1] They also saw action against Libya in 1986, and against Iranian targets in the Persian Gulf during Operation Praying Mantis in April 1988.
Navy A-7s were still effective in the first Gulf War, using Walleye TV guided bombs, HARMs, and laser bombs to attack Iraqi targets. Tanker A-7s also performed well.
By the second Gulf War, the A-7s had been retired. The last mission of A-7s in active duty was the testing of anti-radar equipment for the F-117. The plane has been replaced in the Navy by the F-18 Hornet and in the Air Force, by the A-10.
Operators
Greece
Greece operates two A-7 squadrons, which have been much upgraded with superior avionics and arms capability, under the name of A-7H and A-7E. They are used for ground attack missions, although they also use some variants as training aircraft.
Portugal
Portugal ordered 20 A-7 airframes in 1980, and later purchased six training aircraft and 24 other A-7's. Corsair II's logged over 64,000 flight hours in the Portugese Navy before being retired in 1999.
Thailand
Thailand purchased fourteen A-7E's and four TA-7C's in 1995. They are currently operative but not operational.
