The Ling-Temco-Vought A-7 Corsair II is a carrier-based subsonic light attack aircraft introduced to replace the United States Navy's A-4 Skyhawk, initially entering service during the Vietnam War. The Corsair was later adopted by the United States Air Force, to include the Air National Guard, to replace the A-1 Skyraider, F-100 Super Sabre and F-105 Thunderchief. The aircraft was also exported to Greece in the 1970s, and Portugal and Thailand in the late 1980s. The A-7 airframe design was based on the successful supersonic F-8 Crusader produced by Chance Vought. It was one of the first combat aircraft to feature a head-up display (HUD), an inertial navigation system (INS), and a turbofan engine.
Initial operational basing/homeporting for U.S. Navy A-7 squadrons was at NAS Cecil Field, Florida for Atlantic Fleet units and NAS Lemoore, California for Pacific Fleet units. This was in keeping with the role of these bases in already hosting the A-4 Skyhawk attack squadrons that would eventually transition to the A-7. From 1967 - 1971 a total of 27 Navy squadrons took delivery of four different A-7A/B/C/E models. The Vought plant in Dallas, TX employed up to 35,000 workers turned out one aircraft a day for several years to support the Navy carrier-based needs for Vietnam and SE Asia and commitments to NATO in Europe. In 1974, when the USS Midway (CV 41) became the first Forward Deployed Naval Force (FDNF) aircraft carrier to be homeported in Yokosuka, Japan, two A-7B squadrons assigned to Carrier Air Wing FIVE (CVW-5) were concurrently homeported at NAF Atsugi, Japan. In 1978, these squadrons (VA-93 and VA-56) finally transitioned to the much more advanced A-7E model. Six Naval Reserve squadrons would also eventually transition to the A-7, operating from NAS Cecil Field, Florida; NAS Atlanta/Dobbins ARB, Georgia; NAS New Orleans, Louisiana; NAS Alameda, California and NAS Point Mugu, California. An additional active duty squadron stood up in the 1980s, Tactical Electronic Warfare Squadron 34 (VAQ-34) at NAS Point Mugu, which would operate twin-seat TA-7C and EA-7L aircraft with both a pilot and a Naval Flight Officer in an adversary electronic warfare role.
