The McDonnell Model 86, also known as the XF-85 Goblin, is a unique and unconventional American experimental aircraft developed during the mid-1940s. It is notable for its small size and innovative concept as a "parasite fighter." The XF-85 Goblin was designed to be carried and launched from a mother aircraft, specifically the B-29 Superfortress, to provide additional defense against enemy aircraft.

The XF-85 Goblin's compact size and design were aimed at enabling it to be carried inside the bomb bay of the B-29 and launched when needed. It featured a single turboprop engine and a unique tricycle landing gear arrangement. Although the concept was innovative, the XF-85 Goblin had limited success, with only prototypes built, and the program was eventually canceled.
