The squadron was first activated in April 1942. After training in the United States, the squadron deployed to China in early 1943. It engaged in combat, primarily in China and Southeast Asia until June 1945, when it assumed a mainly transport role. It was awarded two Distinguished Unit Citations for its operations in China and its attacks on Japanese shipping. At the end of 1945 it returned to the United States for inactivation.
The squadron was redesignated the 375th Reconnaissance Squadron and activated in Alaska in 1947. It was inactivated in 1949. It returned to its bombardment designation in 1951 and operated Boeing B-47 Stratojets for Strategic Air Command. In 1959 it moved as part of a test of a "super wing" concept, but was not operational until in inactivated in 1961.
The following month, a fresh cadre taken from the 39th Bombardment Group joined the group. In addition to its own training activities, at the beginning of October, the unit was briefly designated as an Operational Training Unit[4] The squadron began its movement to the China Burma India Theater in January 1943.[1] The air echelon ferried its Liberators across the Atlantic and Africa, leaving from Morrison Field, while the ground echelon moved by ship across the Pacific.[3][4]

In late March 1943, the squadron arrived at Chengkung Airfield, China. In order to prepare for and sustain combat operations in China, the squadron had to conduct numerous flights over the Hump transporting gasoline, lubricants, ordnance, spare parts and the other items it needed. The 375th supported Chinese ground forces and attacked airfields, coal yards, docks, oil refineries and fuel dumps in French Indochina. It attacked shipping, mined rivers and ports and bombed maintenance shops and docks at Rangoon, Burma and attacked Japanese shipping in the East China Sea, Formosa Straits, South China Sea and Gulf of Tonkin. On 21 August 1943, the squadron conducted an unescorted bombing attack on docks and warehouses at Hankow, China, pressing its attack despite heavy flak and fighter opposition. For this mission it was awarded a Distinguished Unit Citation (DUC). Its operations interdicting Japanese shipping in 1944 and 1945 earned it a second (DUC).[3]
The squadron moved to Rupsi Airfield, Assam, India in June 1945. Its mission again was primarily air transport as it ferried gasoline and supplies from there back into China. The unit sailed for the United States in October 1945, and it was inactivated at the Port of Embarkation on 6 January 1946.[1][3]
It was reactivated a few months later in October as the 375th Bombardment Squadron with new Boeing B-47E Stratojet swept-wing medium bombers, capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. In the early late 1950s, the B-47 was considered to be reaching obsolescence and was being phased out of SAC's strategic arsenal. B-47s began being sent to AMARC at Davis-Monthan in July 1959 and the squadron went non-operational. Was inactivated on 25 June 1961.[citation needed]
