The F-82 was the last propeller-driven fighter acquired in quantity by the Air Force. Although it appeared to be two Mustang fuselages on one wing, it was a totally new design built to carry 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 World War II, radar-equipped F-82s were used extensively by the Air Defense Command as replacements for the P-61 night fighter. During the Korean War, Japan-based F-82s were among the first aircraft to operate over Korea, and on June 27, 1950, F-82G all-weather interceptors shot down the first three North Korean airplanes destroyed by U.S. forces. The pilot of this aircraft was Lt. William G. Hudson of the 68th All Weather Fighter Squadron assigned to the 5th Air Force. Armament consisted of six .50-caliber machine guns as standard, with some models carrying eight additional guns in a special center-section nacelle, 25 rockets mounted on racks underneath the wings, or 7,200 pounds of bombs.
