Staging through Hsinching from its base at Chakulia, India, on June 15 the group participated in the first American Air Force attack on the Japanese Home Islands since the Doolittle raid in 1942. Operating from bases in India, and at times staging through fields in China, the group struck such targets as transportation centers, naval installations, iron works, and aircraft plants in Burma, Thailand, China, Japan, Indonesia, and Formosa, receiving a Distinguished Unit Citation for bombing iron and steel works at Yawata, Japan, on August 20, 1944.
Effective 6 April 1944, Hsinching Airfield was also the forward headquarters of XX Bomber Command while its rear echelon remained at Kharagpur Airfield in India. When the B-29 bombers were moved from India in February 1945 to the newly captured bases in the Mariana Islands, the B-29 use of Hsinching Airfield ended.
From 2nd WRS Squadron History obtained from Air Force Historical Research Agency
At the request of the XX Bomber Command, preparations for sending a 2nd Weather Reconnaissance Squadron flight to China began during the latter part of November (1944). It was decided that "C" Flight, with Capt Jean W Dixon as flight commander would undertake the initial assignment in the forward area. The flight consisted of Capt Dixon and crew, 1st Lt Joseph Shannon and crew, and 1st Lt James R Malin and crew with B-25D aircraft nos. 673, 674 and 675. On 22 November, key ground personnel of "C" flight arrived at Hsing Ching Army Air Base, while the squadron aircraft arrived 25 November.
"C" flight operations were so arranged as to provide weather recon of the North China sectors several days prior to the first B-29 raid in each of the series of missions run by the XX Bomber Command from the Chengtu area. Recon to the North continued a day prior to the actual running of the B-29 missions. Our aircraft provided a route weather coverage within a 700-statute-mile (1,100 km) radius of action, with particular attention given to icing conditions, cloud levels, and turbulence and winds, together with a visual check of the predetermined rendezvous area.
The Americans used the airfield as a communications station for the remainder of the war, and turned over the airfield to the Chinese government on 29 August 1945.
