The A-7D is a single-seat, tactical close air support aircraft. Although designed primarily as a ground attack aircraft, it also can be used in air-to-air combat. It was derived from the basic A-7 originally developed for the U.S. Navy. The first USAF A-7D made its initial flight on Apr. 5, 1968, and deliveries of production models began on Dec. 23, 1968. By the time A-7D production ended in 1976, 459 had been delivered to the USAF. In 1973, the USAF began assigning them to the Air National guard (ANG) and by 1987 they were being flown by ANG units in ten states and Puerto Rico. The A-7D demonstrated its outstanding capability to attack ground targets while flown by the 354th Tactical Fighter Wing at Korat RTAFB, Thailand, during the closing months of the war in Southeast Asia. The Corsair II achieved its excellent accuracy with the aid of an automatic electronic navigation and weapon-delivery system.

There are 4 known Vought A-7 Corsair IIs on display in Wisconsin.
