The General Dynamics Model 100 was a 1960s proposal for a counter-insurgency (COIN) ground attack aircraft intended for use by the United States Air Force (USAF).
The Model 100 was conceived by General Dynamics in 1966 as a response to a USAF requirement for a COIN aircraft to replace the Douglas A-1 Skyraider. The initial design featured a turboprop-powered aircraft with straight wings and a T-tail, but a later design had a conventional tail design. Although the Model 100 was referred to as A-8A, it is unclear if the USAF ever officially assigned the designation to the Model 100.
The Model 100 was eventually shelved in favor of the A-X program that would result in the development of the Fairchild Republic A-10 Thunderbolt II.
