The 485th Bombardment Group was a B-24 group that fought with the Fifteenth Air Force in Italy from May 1944 to April 1945, mainly taking part in the strategic bombing offensive.
The group was formed in the United States in September 1943. In March-April 1944 the group moved to the Mediterranean with the ground echelon going to Italy and the air echelon to Tunisia for extra training. The group entered combat in May 1944 and spent most of the war attacking strategic targets across occupied Europe and Germany. The group was awarded a distinguished unit citation for an attack on an oil refinery at Vienna on 26 June 1944.
The group also took part in a number of tactical missions. During the advance on Rome the group was one of ten B-24 groups that took part in a 17 May 1944 attack on the harbours at Piombion, San Stefano and Porto Ferraio on Elba as part of the campaign to prevent supplies from reaching the German front line. In August 1944 it attacked bridges, harbours and German troops to support Operation Dragoon, the invasion of the south of France. In March and April 1945 it was used to support the British Eighth Army during the final offensive in the north of Italy.
In May 1945 the group returned to the United States, and in August it was redesignated as the 45th Bombardment Group (Very Heavy). It began to train with the B-29 but never used it in combat. It was assigned to Strategic Air Command on 21 March 1946 but was inactivated on 4 August 1946.
