RAF Chengtu was built prewar and occupied by the United States Army Air Forces.

The airfield was used as a major command and control base for the Tenth Air Force’s 312th Fighter Wing from July 1944 to August 1945.

[1][2] On August 20, 1944, 61 B-29s from the Twentieth Air Force bombed the Yawata Steel Works in Japan.

They were also trained to fly the Mosquito, however RAF officers were pessimistic about ever making good flyers out of the students.

[4][5] During Mid World War II, Chinese and British forces mainly fought in Burma to repel the Japanese advance, while American and Chinese fighter pilots protected the route in the Himalayas (known as “The Hump”).
