The 501st Bombardment Group was a B-29 Group that entered the campaign against Japan late in the war and focused its efforts against the Japanese petrol industry.
The group was formed in the US in June 1944. It moved to Guam in March-April 1945, where it joined the Twentieth Air Force. Its first combat mission was a practice run against Japanese held Truk on 19 June 1945. This target was used as the Japanese defenders lacked the ability to hurt the high flying B-29s. The first attack against Japan came on 27 June 1945, and after that the group focuses its efforts against the Japanese petroleum industry on Honshu. It was awarded a Distinguished Unit Citation for a series of attacks in July 1945 hitting the Maruzen oil refinery at Shimotsu, the Utsubo oil refinery at Yokkaichi and the petroleum industrial centre at Kawasaki.
After the end of the war the group was used to drop food and supplies to Allied POWs across Japan, China, Korea and Manchuria before being inactivated on Guam on 10 June 1946.
