## History

The unit was initially organized at Langley Field, Virginia, as the 13th Composite Wing in October 1940. It was assigned to the new Caribbean Air Force as a command organization for units in the Caribbean.
Assigned to Borinquen Field, Puerto Rico, its mission was to provide an air strike force for the defense of Puerto Rico and the U.S. Virgin Islands. During the period 1940 to 1942, the wing controlled 21 Douglas B-18 Bolo medium bombers and 92 assorted fighters in about a dozen groups and squadrons. On 17 April 1942, the wing was inactivated, and its mission was taken over by the VI Interceptor Command, Antilles Air Task Force.
The organization was reactivated as the 13th Bombardment Wing in October 1942 at MacDill Field, Florida under Third Air Force. It was one of three bombardment wing headquarters (12th, 13th, 14th) which were formed at MacDill for deployment to Eighth Air Force in England. The 13th deployed in June 1943. There, it controlled the 95th, 100th and 390th Bombardment Groups under the 3d Bombardment Division, flying Boeing B-17 Flying Fortresses. Controlling the combat operations of the groups, it carried out strategic bombing of enemy aircraft, petroleum, and ball bearing industries as well as German airfields. Later, organizational units took part in the famous raid against the ball bearing industry at Schweinfurt in October 1943 and followed with missions against shipyards and shipbuilding installations at Wilhelmshaven and Bremen. With the end of the war in Europe, it returned to the United States and was inactivated on 17 October 1945.
The wing was redesignated as the 13th Air Division and then activated under Strategic Air Command (SAC) in July 1959. The 13th was one of SAC's first strategic missile command organizations, initially being assigned the 703d and 706th Strategic Missile Wings at Lowry AFB, Colorado with the new SM-68 Titan I ICBM. However, these wings never became operational; instead the division became an SM-65 Atlas organization, controlling the 389th and 451st Strategic Missile Wings. In 1963, it assumed command of the 90th Strategic Missile Wing with the new LGM-30A Minuteman I.
In 1965, the first-generation Atlas intercontinental ballistic missile was taken off alert and its subordinate wings were inactivated. It was briefly assigned some KC-135A Tankers and EC-135 electronic intelligence aircraft after the 98th Bombardment Wing was inactivated at Lincoln Air Force Base, Nebraska afterwards, however the 13th Strategic Missile Division was itself inactivated in July 1966, its mission being taken over by the 821st Strategic Aerospace Division in a SAC reorganization.
