Creation History
The creation of a new 130-mm tank gun was launched in conjunction with the start of the development of new heavy tanks "Object 277" and "Object 770" by decree of the Council of Ministers of the USSR No. 1498-837 of August 12, 1955 . The development was carried out in SKB-172 under the direction of M. Yu. Tsirulnikov . In the spring of 1956, the technical design was completed, and by June 1956, tests of prototypes M-65 began. Work on the M-65 was halted in 1961 by the Decree of the Council of Ministers of the USSR No. 141-5, together with the development of new heavy tanks. In total, at least 10 samples of M-65 were produced [1] .
Construction Description
The main components of the M-65 were: the barrel, ejector and muzzle brake . To facilitate loading in the gun, a mechanized ammunition with an electromechanical rammer was used. The vertical guidance mechanism was hydraulic and consisted of two cylinders located on the left and right sides of the gun. The left hydraulic cylinder also served as a hydraulic stop, and the right stabilized the gun in a vertical plane. In the special eye of the right wall of the enclosure was placed an electromechanical stopper that was activated when the gun was set at the loading angle. The maximum rollback length was 603 mm. M-65 was supplied with the Thunderstorm stabilizer [2] [1] .
Used ammunition
For firing at armored targets, 53-VBR-482 shots with an 53-BR-482 armor-piercing-tracer with a DBR fuse and a full variable charge 54-ЖН-482 were used. In the enemy's manpower and unarmored targets, the shooting was to be fired with 53-VOF-482B shots with high-explosive fragmentation grenades 53-OF-482M with an RGM-2 fuse and a full variable charge 54-GH-482 or 53-VOF-482VU shots with fragmentation - high-explosive grenades 53-ОФ-482М and variable charge 54-Ж-482У [2] .
At the end of 1959 in the NII-24 for the gun M65 was developed an armor-piercing sub-caliber projectile with a separating tray

Data on the Soviet method of measuring armor penetration. It should be borne in mind that at different times and in different countries used different methods for determining armor penetration. As a consequence, direct comparison with similar data from other guns is often impossible or incorrect. |
Modifications
On the basis of the M-65 cannon, its modification was developed, which received the internal designation M-65GL. The main difference of the M-65GL from the base sample was a caliber of 140 mm and a smooth barrel . Muzzle brake was not installed, and the full length of the barrel was increased by 1250 mm. In the gun M-65GL it was planned to use feathered sub-caliber armor-piercing shells weighing 10 kg. The gun was supposed to be installed in tanks Object 278 , Object 279 and Object 770 . In addition, the M-65GL was proposed for installation in the Taran ACS instead of the M-69 cannon, however, this proposal was not approved by SRI-24 , since a change in caliber would require a re-design of the ACS and would lead to a shift in the development timeframe than a year [4] .
