This is actually P-39Q 44-3887, converted to an RP-39Q two-seat operational training version with armament removed and redesignated TP-39Q in 1945. Disposed of as surplus in 1946, it was restored to single-seat P-39Q status in 1966 and flown to the UASFM. By 1977 it was marked as P-39D 41-7073 flown by the 57th FS, Adak Island, during the harsh conditions of the Aleutians Island campaign of autumn 1942. They attacked the Japanese forces which had invaded Attu and Kiska islands, the weather claiming more casualties than combat

This clever cold-weather diarama at the National Museum of the USAF showcases not only the P-39 but also the versatility of PSP (pierced steel planking) and the Type F-1A Utility Heater.
