On 24 April 1944, the 384th Group, although crippled by heavy losses, led the 41st Bombardment Wing, in an attack on the Dornier Flugzeugwerke aircraft manufacturing plant at Oberpfaffenhofen, pressing the attack through almost overwhelming opposition. One group commander described the opposition on this mission as the heaviest he had seen during the war. This mission resulted in the award of a second DUC to the squadron. Other strategic targets included communications centers, oil refineries and storage facilities at Leipzig and Berlin, marshalling yards at Duren and Mannheim, and port facilities. The squadron was occasionally diverted from the strategic bombing campaign to fly air support and interdiction missions. It attacked targets along the coast of Normandy to support Operation Overlord, continuing these attacks through D-Day, when it attacked airfields and communications facilities beyond the beachhead. On 24 and 25 July 1944, it supported Operation Cobra, the breakout at Saint Lo with attacks on strong points just beyond enemy lines. It hit armor and artillery concentrations near Eindhoven to support Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands during September 1944. It attacked enemy fortifications and communications during the Battle of the Bulge from December 1944 through January 1945. When the Allies attacked across the Rhine in Germany in March 1945, it attacked rail facilities, including marshalling yards and bridges to cut enemy supply lines. The squadron flew its last combat mission on 25 April 1945. After V-E Day the squadron remained in Europe as part of United States Air Forces in Europe. It assisted Air Transport Command in the Green Project by flying soldiers to Casablanca, French Morocco for transport back to the United States. From its continental base at Istres Air Base, France, it flew Greek military back to their homeland, and transported displaced persons. The squadron transported American troops to Germany to serve in the military occupation forces there, but was gradually drawn down. It was inactivated in France in February 1946 and its remaining personnel and equipment were absorbed by the 306th Bombardment Group. The 547th Squadron was reactivated as a reserve unit under Air Defense Command (ADC) at Winston-Salem Municipal Airport, North Carolina in July 1947, nominally as a Boeing B-29 Superfortress unit. The squadron was assigned to the 96th Bombardment Group, which was located at Gunter Field, Alabama. It is not clear whether or not the squadron was fully staffed or equipped.
