LTV A-7 Corsair II
The LTV A-7 Corsair II is an American carrier-capable subsonic light attack aircraft designed and manufactured by Ling-Temco-Vought (LTV).
The A-7 was developed during the early 1960s as replacement for the Douglas A-4 Skyhawk. Its design was derived from the Vought F-8 Crusader; in comparison with the F-8, the A-7 is both smaller and restricted to subsonic speeds, its airframe being simpler and cheaper to produce. Following a competitive bid by Vought in response to the United States Navy's (USN) VAL (Heavier-than-air, Attack, Light) requirement, an initial contract for the type was issued on 8 February 1964. Development was rapid, first flying on 26 September 1965 and entering squadron service with the USN on 1 February 1967; by the end of that year, A-7s were being deployed overseas for the Vietnam War.
Initially adopted by USN, the A-7 proved attractive to other services, soon being adopted by the United States Air Force (USAF) and the Air National Guard (ANG) to replace their aging Douglas A-1 Skyraider and North American F-100 Super Sabre fleets. Improved models of the A-7 would be developed, typically adopting more powerful engines and increasingly capable avionics. American A-7s would be used in various major conflicts, including the Invasion of Grenada, Operation El Dorado Canyon, and the Gulf War. The type was also used to support the development of the Lockheed F-117 Nighthawk.
The A-7 was also exported to Greece in the 1970s and to Portugal in the late 1980s. The USAF and USN opted to retire their remaining examples of the type in 1991, followed by the ANG in 1993 and the Portuguese Air Force in 1999. The A-7 was largely replaced by newer generation fighters such as the General Dynamics F-16 Fighting Falcon and the McDonnell Douglas F/A-18 Hornet. The final operator, the Hellenic Air Force, withdrew the last A-7s during 2014.
In 1960, officials within the United States Navy (USN) began to consider the need to replace its existing fleet of Douglas A-4 Skyhawk, a light attack aircraft. At that time, it was not clear that the A-4 would eventually remain in production until 1979; furthermore, according to aviation authors Bill Gunston and Peter Gilchrist, some figures believed there to be an unmet requirement for a more capable attack platform that could routinely attain supersonic speeds, carry heavier payloads, and fly further than its predecessors. Proponents of a new attack aircraft included Secretary of Defense Robert McNamara, who urged the Navy's consideration on the matter.
In December 1962, the Sea-Based Air Strike Forces (SBASF) study group started examining detailed performance and cost evaluations on the topic. The group analyzed a total of 144 hypothetical aircraft to support their findings. According to Gunston and Gilchrist, a major finding from these studies was that a subsonic aircraft would achieve superior performance to a supersonic one. By foregoing a supersonic capability, the airframe could be smaller, cheaper, and easier to manufacture; considerably larger quantities of such an attack platform could be procured over a supersonic counterpart. Development speed was also increased by sticking to subsonic speeds, which was a further advantage. A particular emphasis was placed on the accurate delivery of weapons, which would reduce the munitions costs per target.[citation needed]
On 17 May 1963, these criteria were formulated into a draft requirement, known as VAL (Heavier-than-air, Attack, Light). On 29 May 1963, the request for proposals (RFP) associated with the requirement was issued. To minimize costs, all proposals had to be based on existing designs. Accordingly, Vought, Douglas Aircraft, Grumman and North American Aviation chose to respond. The Vought proposal was based on their successful F-8 Crusader fighter and sharing a similar configuration; however, it had a shorter airframe with a rounded nose, giving the aircraft a "stubbier" appearance.
All bids were received by September 1963 and the evaluation process was completed in early November of that year. On 8 February 1964, funding for VAL was approved by Congress, enabling the programme to proceed; three days later, Vought's submission was selected as the winner. On 19 March 1964, Vought received a contract from the Navy for the manufacture of the initial batch of aircraft, designated A-7. On 22 June 1964, the mock-up review took place. In 1965, the A-7 received the name Corsair II; Vought had previously produced three aircraft known as "Corsair". During the 1920s, they had produced the O2U Corsair biplane scout and observation aircraft and the SBU Corsair scout bomber of the 1930s. During World War II, the firm made the successful F4U Corsair. The name Corsair II reflects the well-known F4U Corsair, which famously served as a capable fighter bomber in World War II and the Korean War. It was supposed to establish a lineage between the aircraft from the same manufacturer and intended for the same ground attack role.[citation needed]
