 While the modified Hawk 75M with retractable landing gear was created specially for China, it was not widely used in the war against the Japanese, in spite of the fact that 30 aircraft, and 82 kits for assembly were delivered in the summer and autumn of 1938.It was planned to assemble the Hawk in a factory operated by the Central Aircraft Manufacturing Company, which had been evacuated from Hankou to Loiwing.The latter location, not far from the Burmese border on the eastern bank of the Ruiluqiang River in Yunnan Province, at that time seemed protected from Japanese attacks, but technical difficulties plagued the actual assembly of the Hawk 75 in that location.
