Following V-J Day, it returned to the United States and was inactivated. The squadron was activated in the reserve in 1947, but was discontinued when Continental Air Command reorganized its reserve units under the wing base organization plan and reduced their number due to budget constraints.

After moving to Chakulia Airfield, the squadron began combat operations, flying its first mission on 10 January 1943. For the remainder of the year the squadron was primarily tasked with interdicting Japanese lines of communication in Burma. The squadron was transferred to Fourteenth Air Force and  moved to China in January 1944. Again the squadron's primary tasking was interdiction of Japanese lines of communication in China and eastern French Indochina (now Vietnam). In addition to strikes against airfields, bivouac and storage areas and bridges, the unit performed target of opportunity sweeps along roads, rivers and over the Gulf of Tonkin and the South China Sea. When Japan surrendered, sixteen squadron aircrews and several aircraft maintenance personnel were in India undergoing transition training to Douglas A-26 Invader.
