Artillery system 21-K, according to design documentation, is an adaptation of a 45-mm anti-tank Cannon of the 1932 model of the year (19-K) to a marine machine. The body of the 21-K Cannon was borrowed from the 19-K Cannon and consisted of a fastened barrel and casing.

Closing the shutter when sending the next cartridge, and opening manually. In systems 21-K, produced after 1935, semi-automatic inertial type was introduced - opening the shutter after a shot is now automatic.

Barrel 21-K from a pipe and a casing, put on a pipe in a hot state and constituting a whole with the breech of the Cannon. Cannons of later production had a monoblock barrel. Tool machine - curbstone. The Cannon had no shield.
