The squadron was occasionally diverted from its strategic bombing mission to fly interdiction and close air support missions. It bombed V- weapon launch sites, airfields and transportation facilities to support Operation Overlord, the invasion of Normandy, and on D-Day attacked coastal defenses and choke points on German lines of communication. It struck enemy positions to assist the allied attacks on Caen and Operation Cobra, the breakout at Saint Lo. It dropped supplies to allied troops during Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands. During the Battle of the Bulge, it attacked transportation and communications targets in December 1944 and January 1945. In the spring of 1945, it again dropped supplies to airborne troops in Operation Varsity, the airborne assault across the Rhine near Wesel. The squadron flew its last combat mission on 25 April 1945, an attack on a railroad yard near Salzburg, Austria.
