Operating air defense patrols throughout 1943 from La Joya, pn 9 February 1944, the squadron finally moved to Howard Field, having been deployed to an auxiliary base longer than any other Squadron in Sixth Air Force. In March, the squadron was selected to serve as a "model" squadron for the Brazilian 1st Fighter Squadron, which was in training with the 30th Fighter Squadron at Aguadulce Field. During this operational observation, four Brazilian officers and 36 enlisted men were briefly attached to the squadron. Moved back to Howard Field in August 1943. One more move was made to France Field on 10 January 1945, replacing the 32d Fighter Squadron.
