The Convair XFY-1 Pogo was an experimental V/STOL (vertical takeoff and landing) aircraft developed during the early years of the Cold War. It was intended to be a high-performance fighter aircraft capable of operating from small warships.

Ultimately, technical and operational challenges, along with the superiority of jet-engined fighters, led to the project's suspension in 1955. The XFY-1 Pogo is now preserved in the National Air and Space Museum.
