Operational history
Constituted as 331st Bombardment Group (Heavy) on 1 Jul 1942 and activated on 6 July at Salt Lake City AAB, Utah. Assigned to Second Air Force. The mission of the 331st was initially that of a replacement training unit. Equipped with B-17's and B-24's for duty as a replacement training unit at Casper AAFld, Wyoming.

The 331st, as well as the entire 315th Bomb Wing, was assigned the B-29B model. This model was built at Bell-Atlanta. The B-29B was a limited production aircraft, built soley by Bell-Atlanta. It had all but the tail defensive armament removed, since experience had shown that by 1944 the only significant Japanese fighter attacks were coming from the rear. The tail gun was aimed and fired automatically by the new AN/APG-15B radar fire control system that detected the approaching enemy plane and made all the necessary calculations. The elimination of the turrets and the associated General Electric computerized gun system increased the top speed of the Superfortress to 364 mph at 25,000 feet and made the B-29B suitable for fast, unescorted hit-and-run bombing raids and photographic missions.
