In 1934–1935 the design bureau of the Kharkiv Locomotive Factory developed this artillery modification of the BT-7. The new elliptical turret was equipped with the 76.2-mm CT-28 gun. In addition, some vehicles received new radio stations. A total of 155 artillery BT-7s were manufactured. The vehicles saw combat on the Karelian Isthmus, in Manchuria, and during the first period of the Great Patriotic War.
