Кировский завод
The decision to initiate development of larger caliber divisional guns was made in the second half of 1937. Late that year the 95 mm was proposed. On 10 March 1938 the Main Directorate of Artillery (GAU) initiated work on a 95 mm divisional gun at the Kirov Plant and the No. 92 Plant. The former quickly abandoned the development, but the UZTM Uralmash production facility swiftly joined the program. Both guns were supposed to have a companion piece in the form of the 122 mm howitzer.
