The group occasionally flew air interdiction and air support missions. It helped to prepare for the invasion of Normandy by bombing airfields, V-1 and V-2 launch sites, and other targets. The unit attacked shore installations on D-Day, 6 June 1944 with 81 sorties and supported ground forces at Saint-Lô by striking enemy defenses in July 1944. During the Battle of the Bulge, between December 1944 and January 1945 it bombed German communications. Early on 24 March 1945 the 445th dropped food, medical supplies, and ammunition to troops that landed near Wesel during the airborne assault across the Rhine and that afternoon flew a bombing mission to the same area, hitting a landing ground at Stormede.
