Fenghuangshan Airport, also known as Chungsing Chang, Fenghwangshan and Makiashipen was built under the directives of Sichuan warlord Liu Xiang in 1931 for his fledgling air force operations, and was integrated into the centralized operations of the Chinese Nationalist Air Force as the War of Resistance-World War II was starting with the invasion and occupation by the Empire of Japan; Fenghuangshan served as an operations base for Chinese fighter squadrons during the terror bombings of Chengdu and Chongqing, and was regularly under bombing attack by Japanese. Fenghuangshan was also the base where Captain Xu Huansheng and his B-10 bomber crews initially trained for the planned transoceanic strategic bombing mission against the Empire of Japan in 1938. Years later, after the United States became involved in World War II, it was a major command and control base for Tenth Air Force, being the home of the 312th Fighter Wing from July 1944 until August 1945. The wing commanded three fighter groups (33rd, 81st and 311th) in central China as well as provided support to Twentieth Air Force B-29 Superfortress groups which staged strategic bombardment missions over Japan though bases in the Chengdu area from their home bases in India (see: Operation Matterhorn).
