The group was occasionally diverted from the strategic bombing mission to perform air interdiction and close air support missions. In August 1944, it supported Operation Dragoon, the invasion of southern France by attacking submarine pens, marshalling yards and artillery batteries in the area of the amphibious landings. It struck lines of communications, railroads, ammunition dumps and other targets in connection with Operation Grapeshot, the allied offensive in Northern Italy. The 460th was redesignated as the 460th Bombardment Group, Heavy on 3 September 1944. The group flew its last mission against a target in northern Italy on 26 April 1945.
