North American F-82 Twin Mustang

The article discusses the North American F-82 Twin Mustang, an operational combat escort fighter developed from the famous P-51 Mustang. While the design may appear as if two P-51s were mated together, it played a significant role post-World War II. Initially designed to escort the B-29 Superfortress, it entered WWII too late. However, it became a vital asset during the Korean War and served as an interceptor in Alaska. The F-82 gained notoriety when a P-82B "Betty Jo" set a record for the longest non-stop flight by a propeller-driven fighter, a record that still stands today.

Despite perceptions, the F-82 shared only 20% commonality with the P-51. It featured two fuselage sections with additional modifications, including extended sections and a center wing equipped with six .50-cal. machine guns. Initially powered by Packard-built Merlin engines, later versions used less potent General Motors Allison engines, resulting from increasing licensing fees. With pilots able to swap controls during long missions, the F-82 had significant usage in Alaska for weather operations and patrolling Alaskan villages. The aircraft was eventually replaced by the F-94 Starfire due to maintenance requirements of extended missions.
