The P-82/F-82 Twin Mustang was a long-range escort fighter that was developed by the United States during World War II.
The first production model of the P-82 series was the P-82B model. Being based on the airframes of two P-51H Mustang fighters, the twin mustang was equipped with two Packard V-1650 Engines that were capable of propelling it at speeds of up to 775 km/h. The aircraft was designed to be able to escort American B-29 bombers over Japan at distances exceeding the range of conventional P-51 Mustangs or P-38 Lightning fighters. Interestingly, both pilots of the aircraft could take control, alternating on long flights. The total operational range of the Twin Mustang was around 3,500 kilometers while its service ceiling was approximately 12,160 meters.
The total weight of the aircraft was about 11,200 kg fully combat loaded while total length was 11.5 meters, and wingspan was 15.5 meters. Armament consisted of six 12.7mm machine guns mounted in the centerline 'wing' with the capability to carry a payload of up to 1,800 kg worth of bombs and rockets.
