The A-7D demonstrated its outstanding ground attack capability flying with the 354th Tactical Fighter Wing (TFW) at Korat Royal Thai Air Force Base, Thailand, during the closing months of the Vietnam War.

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.

The A-7D is a single-seat, tactical close air support aircraft derived from the U.S. Navy's A-7. The first A-7D made its initial flight in April 1968, and deliveries of production models began in December 1968. When A-7D production ended in 1976, LTV …

During the Vietnam conflict, A-7s operating from aircraft carriers were successfully employed by the Navy in just about every conceivable attack role. The Air Force operated A-7Ds from bases in Thailand, but by time they arrived in Southeast Asia, most of the American ground troops had been withdrawn.

A-7Ds from Korat flew combat operations over Vietnam until mid-Jan 1973, in Laos until 22 February 1973, and in Cambodia until 15 August 1973. The last shot fired in anger by United States military forces in Southeast Asia was fired by an A-7D of the deployed 345th TFW / 353 TFS assigned to Korat RTAFB on 15 August 1973.

The A-7A started production in 1966 and saw action in Vietnam. The USAF developed the A-7D in 1968 with improved avionics, a stronger engine, and an M61 Vulcan cannon. Over 450 A-7D units were produced from 1968 to 1975.

Both the A7-D and the A-7E aircraft went on to establish an impressive string of combat successes in Vietnam. A-7: Genesis of the Navy Attack Bomber, Light (VA(L))

Following the close of U.S. involvement in Vietnam, A-7Ds were assigned to the Air National Guard (ANG) units; by 1987 they were being flown by ANG units in ten states and Puerto Rico. A-7Ds were retired in 1993 after replacement by F-16 Falcons.

The A-7Ds flew strikes against targets in Laos, Cambodia and North Vietnam. In the two years that the A-7D was in combat over Southeast Asia only four were lost, a real tribute to the toughness of the aircraft and crews.

By the end of that year USN pilots of VA-147 were flying the Corsair II in combat in Vietnam. The 511 TFS became the first combat-capable USAF A-7 unit on 2 March 1971.
