The McDonnell XF-85 Goblin was a fighter aircraft, conceived during World War II and intended to be carried in the bomb bay of the giant Convair B-36 bomber as a defensive parasite fighter. Its first flight was on 23 August, 1948.
Two prototypes were built, and both still survive; one in the USAF Air Museum at Wright-Patterson Air Force Base in Ashland, Ohio and the other at the Strategic Air Command Museum outside Omaha, Nebraska.
Four factors combined to kill the XF-85 program.
All tests undertaken on the XF-85 were carried out using a Boeing B-29 Superfortress bomber because a prototype B-36 was unavailable. Later, a B-36 was used as a mother ship for similar tests, carrying a conventional Republic F-84 Thunderstreak fighter. These tests, known as FICON (Fighter-in-Convair) experiments, were also found to be of little long term practical use and the whole concept was dropped.
