development
In 1945, work began on a 25 mm anti-aircraft gun, which was to be used mainly in smaller classes of ships such as torpedo speedboats and submarines . The gun was produced in series from 1950 to 1984 and installed in more than 30 ship classes. A special version 2M-8 for use in submarines was developed until 1954, but its use is unknown, as no more guns were used on Soviet submarines at the end of the 1950s.
A modified version is called 2M-3M.
