The F-82 was the last propeller-driven fighter acquired in quantity by the U.S. Air Force. It appears to be two P-51 Mustang fuselages on one wing, but in reality it was a totally new design. The Twin Mustang carried a pilot and co-pilot/navigator to reduce fatigue on long-range bomber escort missions. Production deliveries did not begin until early 1946, too late for World War II. After WWII, Air Defense Command flew radar-equipped F-82Gs as replacements for the P-61 night fighter. During the Korean War, Japan-based F-82Gs were among the first USAF aircraft to operate over Korea. On June 27, 1950, all-weather F-82Gs shot down the first three North Korean airplanes destroyed by U.S. forces.
