The North American F-107 Ultra Sabre is the only American jet fighter ever to have an air intake on the top of its fuselage.
Three aircraft were built in answer to U.S.A.F. requirements for a fighter/bomber to deliver a nuclear payload while flying at up to twice the speed of sound.
To make room for the fire control radar, the engine air intake of the F-107 was moved to the top of the fuselage behind the cockpit.
Rather than ailerons, the aircraft used spoilers which allowed it to roll at supersonic speeds.
Other features of the aircraft included an all-moving vertical fin and a variable area inlet duct to automatically control the air intake to the engine.
The F-107 never went into production.

I have finished, and flown last year, a 1/7.5 scale North American F-107 that has been scratch built. The airplane is powered by a TJT-300 turbojet, and is currently being "re-engined," along with receiving additional detail. Enclosed is a picture that I happen to have on hand."
The rc F-107 built by Mike Dudley has a 30" wingspan. Power comes from a 68 mm EDF. Weight is about 1 3/4 lbs.
