Aviation X-Ray - The F-107 and the J75 Engine

The North American F-107 was North American Aviation's  entry in a U.S. Air Force tactical fighter-bomber design competition of the 1950s. The F-107 incorporated many innovations and radical design features, and was based on the F-100 Super Sabre. The competition was eventually won by the F-105 Thunderchief, and the F-107 prototypes ended their lives as test aircraft. 

The powerplant used in the prototype F-107A was the YJ75-P-11. The J75 engine was intended to meet the requirements for the next generation of supersonic aircraft.

  1. It's amazing how far aircraft hardware has gone since its dawn. I guess there's no reason for it not to, not with all the billions of dollars worth of investment.
