Eleventh Air Force
Six months after Eleventh Air Force had been redesignated in Alaska, another headquarters, also named Eleventh Air Force, was established on 13 May 1946 and activated at Olmsted Field, Pennsylvania, on 13 June 1946. This new organization was assigned to Air Defense Command.
Japanese Eleventh Area Army
The Japanese 11th Area Army was formed on February 6, 1945 under the Imperial General Headquarters and transferred to the control of the Japanese First General Army on April 8, 1945. It was part of the last desperate defense effort by the Empire of Japan to deter possible landings of Allied forces in central Honshū during Operation Downfall (or in Japanese terminology). The Japanese 11th Area Army was responsible for the Tōhoku region of Japan and was headquartered in Sendai, Miyagi.
