An experimental plane from the 1950s. It was an attempt to make a VTOL Supersonic fighter-bomber.

This prototype supersonic bomber was conceived in the late 50s and flew in the mid-60s. The bomber development was cancelled due to the development of ICBMs and surface-to-air missile systems, but three were built to test aspects of supersonic flight. This is the only remaining plane of the three built.
