Flying Aircraft Carriers of the USAF: McDonnell Xf-85 Goblin

The P-85 Goblin was the only airplane that ever flew which was designed from scratch to be operated entirely from another airplane. The development of the B-36 by the Consolidated Vultee Aircraft Corporation of Fort Worth, Texas resulted in a requirement for fighter protection for the bomber at distances from any friendly base that far exceeded the range of currently available escort fighter airplanes. Due to the inability of contemporary fighters to escort B-36 bombers all the way to their targets, the Army Air Corps initiated Project MX-472, Unconventional Fighter Design Studies, on December 3, 1942. The primary objective of the project was the development of a suitable method of protecting the B-36 on long-range bombing missions. The McDonnell Aircraft Corporation designed the P-85 Goblin to fit entirely within the confines of the bomb bay of the B-36. The little fighter was just fifteen feet long with a wing sapn of twenty-one feet.
