History
Constructed and maintained facilities, February-December 1918. Apparently never active during period 1924-1942 when allotted to the reserve with assignment to Ninth Corps Area and designated station at Seattle, Wash.
Constituted 491st Bombardment Squadron (M) on August 2, 1942, the B-25 Mitchell bomber squadron was activated in place at Karachi, India on September 15, assigned to the newly activated 341st Bombardment Group, Tenth Air Force. Full complement of aircraft and personnel was not achieved until the end of the year. After moving to Chakulia Air Base, the squadron began combat operations with its first mission January 10, 1943. For the remainder of the year the squadron was primarily tasked with interdicting Japanese lines of communication in Burma.
Reassigned along with HQ 341st and 22nd Bombardment Squadron (M) to Fourteenth Air Force in China, January 1944. Again the 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, they performed target of opportunity sweeps along roads, rivers and over the Gulf of Tongking and the South China Sea.
When Japan surrendered sixteen Squadron aircrews and several aircraft maintenance personnel were in India undergoing transition training to A-26 Invader. On/about August 31, 1945 the remaining 491st personnel were transferred to join those in India. Those determined to meet requirements embarked on a transport ship, when it became available, and returned to the United States, arriving on November 1st. These personnel were demobilized and the Squadron inactivated at Newark, New Jersey on November 1-2, 1945.
Postwar -- redesignated 491st Bombardment Squadron (Light)on May 26, 1947; activated in the Air Force reserves on June 5th and inactivated June 27, 1949.
Again redesignated 491st Bombardment Squadron (Medium) on August 20, 1958, the squadron was activated November 1st, and assigned to the 341st Bombardment Wing at Dyess Air Force Base, operating the B-47 Stratojet. As a result of Strategic Air Command phasing out the B-47, and the replacement of the B-47 by B-52 Stratofortress, in March 1961, President John F. Kennedy directed that the phaseout of the B-47 be accelerated. The squadron was inactivated on 25 June 1961 as part of that draw down, and the aircraft were sent to AMARC storage at Davis-Monthan.
