Sioux City Air National Guard Base -- The Ling-Temco-Vought A-7D Corsair II on display at the Iowa Air National Guard in Sioux City, Iowa, tail number is 75-0406. The Iowa Air National Guard’s 185th Tactical Fighter Group flew Corsairs from March 1977 to December 1991.
According to the National Museum of the U.S. Air Force, 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 had delivered 459 to the U.S. Air Force.
In 1973 the USAF began assigning A-7Ds to the Air National Guard, and by 1987 they were being flown by ANG units in 10 states and Puerto Rico. The last A-7Ds were retired in the early 1990s.
The plaque in front of the aircraft in Sioux City reads:
The A-7D is a single-seat, tactical close air-support aircraft. Although designed primarily as a ground attack aircraft, it also has limited air-to all combat capability. It was derived from the basic A-7originally developed by LTV for the U.S. Navy. The first A-7D made its initial flight on April 5, 1968 and deliveries of production models began on December 23, 1968. When A-7D production ended in 1976, 459 had been delivered to the USAF. In 1973, the USAF began assigning A-7Ds to the Air National Guard (ANG) and by 1987 they were being flown by ANG units in ten states and Puerto Rico. The A-7 was used extensively in Vietnam. The Corsair II achieved its excellent accuracy with the aid of an automatic electronic navigation and weapon delivery system. The last aircraft to drop a bomb during conflict was an A-7D later assigned to the 185th. The 185th Tactical Fighter Group flew the A-7D from 1977 until 1991.
