The A-7 Corsair II is a U.S. carrier-capable, subsonic light-attack aircraft built by Vought . Introduced in the late 1960s, it was designed to be a compact, rugged, and accurate strike aircraft that could carry a heavy load for its size and deliver weapons precisely — day or night, and in marginal weather.
