Creation History
Work on the new 122-mm rifled tank gun M-62 was started in the 1940s under the leadership of M. Yu. Tsirulnikov . By 1949, the first prototype was manufactured. In the summer of 1953, the gun passed factory tests at the Gorokhovets artillery range . On February 14, 1955, the GAU approved the technical design of a modified version of the M-62C for installation in a self-propelled artillery installation , and on February 24, 1955, by decree of the Council of Ministers of the USSR No. 347-205, the development of the M-62T2 gun with stabilizer for installation in a heavy tank was started. On October 30, 1955, three prototypes were handed over, and then sent to the Kirov Plant for installation in the T-10M tank . In 1957, an installation batch of 21 guns was released, and since 1958 large-scale production was launched [3] [4] .
Design Description
The main components of 2A17 were: the barrel, which consisted of a pipe that was fastened with a casing, a breech with a guide pin, an ejector and a muzzle brake . The gun used a horizontal wedge type shutter and a semi-automatic copy type. Trigger mechanism galvanic-shock type. The striker was launched using the trigger on the gun guard or using the electromagnet operated by buttons on the remote control of the T2C sight. In order to prevent unauthorized descent, a locking mechanism was installed on the right side of the guard, the lock was removed by the charging mechanism when the handle of the locking drive was turned. The receiver group was mounted in a one- piece cradle of the hollow type. In the lower part of the cradle in special tides, cylinders of recoil devices were fixed. On the right was the roll cylinder, and on the left was the roll brake cylinder. The maximum rollback length was 550 mm. Aiming the gun in a vertical plane was carried out using a sector lift. M-62T2 was equipped with a stabilizer "Rain." [2]
