nearly the next half-century. However, with the change of commands, the mission of Barksdale initially remained that of a training base where units were formed and organized, then were reassigned to front-line operational bases. 91st Strategic Reconnaissance Wing The first SAC unit at Barksdale was the 91st Strategic Reconnaissance Wing was reassigned to the base from McGuire AFB on 1 October. The mission of the 91st was to provide global strategic reconnaissance, with emphasis on aerial photography and mapping. The 91st was equipped with a myriad of aircraft, including versions of the Boeing RB/TRB-17 Flying Fortress; Boeing RB/TB/TRB-29 Superfortress; Douglas RC-54 Skymaster; Boeing B/RB-50 Superfortress, and the North American RB-45 Tornado. The 91st maintained operational detachments of aircraft and crews drawn from several components to provide reconnaissance support in overseas areas, including the United Kingdom and locations in North Africa. Deployments would be routine and last for about three months. When the Korean War broke out in 1950, a three-plane detachment from the wing flew to Johnson Air Base, Japan to provide the Far East Air Forces commander improved reconnaissance capability. The 91st Strategic Reconnaissance Squadron remained in Japan for the duration of the war and flew reconnaissance missions over North Korea and the Sea of Japan. The wing also sent a detachment of RB-29 refueling aircraft, and conducted the first aerial refueling under combat conditions when a KB-29P refueled an RC-45C over North Korea in July 1951 With the arrival of the 376th Bomb wing in October 1951, the decision was made to reassign the 91st. On 16 June 1952 the 91st was reassigned to Lockbourne AFB, Ohio. 301st Bombardment Wing The 301st Bombardment Wing joined the 91st SRW at Barksdale on 7 November 1949, being transferred from Smoky Hill AFB, Kansas, where it was reactivated the year before. Both wings operated a joint integrated headquarters although each wing continued tactical operations independently. Initially flying the B-29 Superfortress, after arriving at Barksdale the 301st was one of the first units to conduct aerial refueling operations with the KB-29 tanker version of the Superfortress. The wing converted to the Boeing B-47 Stratojet in 1953 and traded in its KB-29 tankers for the upgraded Boeing KC-97 Stratofreighter. The mission of the 301st was to train for strategic bombing missions and to conduct aerial refueling. The wing deployed to England in 1953 and to French Morocco in 1954. It was reassigned to
