Vought began manufacture of its F-8 Crusader for the US Navy in 1957; it was one of the first Navy fighters capable of supersonic flight and the Navy's last all-gun fighter. The same basic design was later heavily revised and shortened to produce Vought's A-7 Corsair II, a carrier-borne close air support and attack plane in 1965, an aircraft which became heavily engaged in a variety of close support and strike missions during the Vietnam War, beginning in 1967. The A-7 has also participated in the US invasion of Grenada in 1983; a punitive raid on Syrian missile sites in 1983; reprisal raids against Libya during Operation El Dorado Canyon in 1986; strikes against Iranian coastal platforms and naval forces during Operation Praying Mantis in 1988; support of the 1989 invasion of Panama; and throughout operations during Desert Storm in 1991.
