The unit 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. It attacked shore installations on D-Day, 6 June 1944, 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 702d 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.
