Kirtland Field served as a B-29 Superfortress base in support of the incendiary bombing raids on Japan. In March 1945, Kirtland Field was converted into a Superfortress base in a matter of only 45 days after its assignment to the Second Air Force. The Second Air Force, operating under the Continental Air Forces, concentrated on training for heavy and very heavy bombers during the war. Kirtland Field was one of six stations in the 16th Bombardment Operational Training Wing program. Other locations were Alamogordo Army Airfield and Clovis Army Airfield in New Mexico; Biggs Army Airfield and Pyote Army Airfield in Texas; and Davis-Monthan Army Airfield in Arizona.
