North American P-82 Twin Mustang (S/N 44-83887) in flight with North American P-51D Mustang (S/N 44-84745), between 1947-49.

The North American F-82 Twin Mustang is the last American piston-engined fighter ordered into production by the United States Air Force. Based on the North American P-51 Mustang, the F-82 was originally designed as a long-range escort fighter for the Boeing B-29 Superfortress in World War II. The war ended well before the first production units were operational.
