Production of 2M-3 defensive naval guns was carried out by specialists of a machine-building plant in the city of Tula. The mechanism was constantly upgraded during various engineering and design improvements. New tactical capabilities allowed to use additional power of powder gases, which were removed from the barrel. As a result, the rate increased up to 600 shots per minute.
The 110-PM barrel is fitted with 2x autocannons one above another, so it has the form of a mono-block with a piston valve, which energy is enough to launch the trigger. The rollback of the trigger to the rear position is carried out manually, which ensures the reliability of the autocannon. The 2M-3 can be operated both hydraulically and manually.
There is a spring-loaded mechanism located on the barrel of the gun, which make it possible to shoot more effectively. To elevate the gun, operators use lower cradle with the toothed sector, connected with a gear mechanism. The upper and lower cradle occupy a position that resembles a parallelogram. Due to this equality of angles, there is no overweight.
Hydraulic actuators in the construction of the 2M-3 provide vertical and horizontal guidance (elevation and traverse guidance), as well as reloading of the gun. During firing, the barrel is cooled both by the air and water hose. It takes up to 20 seconds to cool the barrel with water.
The 2M-3 system was supplied on more than 20 land based applications and artillery ships. Currently, these installations are one of the main means in the field of self-defence and navigation forces of Ukraine. It was used in the operations during the Arab-Israeli military conflict. The torpedoes and missile ships in Egypt and Syria also use the 2M-3 type autocannons.
