The prototype Northrop GB-2 Tail-less Radio-controlled Glider Bomb with pilot’s cockpit for controlled gliding tests.

The Northrop N9M-2 eventually served as a training instrument at Northrop Aeronautical Institute. It is seen here in company of the Northrop JB-1a, a piloted glider variant of the JB-1 (MX-543) ‘buzz bomb’.
