In August 1944, the squadron was reactivated as a Boeing B-29 Superfortress unit at Dalhart Army Air Field, Texas and assigned to the 346th Bombardment Group. It trained with Superfortresses at Dalhart and Pratt Army Air Field, Kansas until June 1945, when it began moving to Okinawa to become part of Eighth Air Force. Although the war ended before the squadron could begin operations, a few of its crews formed part of its forward echelon and flew missions with B-29 units of Twentieth Air Force.Maurer, Combat Units, pp. 224–225
