History
The
Soviet Army began looking for a new heavy machine gun to replace its older
SGM and
DShK machine guns in the early 1950s. The Soviet Army liked the idea behind the German
MG 42: a versatile weapon used on a variety of mounts to perform many different roles. Two Soviet weapon designers were asked to design one weapon each utilizing the same principle.

's submission was approved following trials as it was found to be more reliable and cheaper to manufacture than the design of Grigory Nikitin and Yuri Sokolov. Kalashnikov's machine gun became the new standard machine gun, and was named
PK.
Nikitin's and Sokolov's design was, however, not forgotten. It was eventually developed into the NSV heavy machine gun about 10 years later and selected in 1969 as the successor to the
DShK and DShKM machine guns. It was accepted in service by the Soviet Army in 1971.
Following the break-up of the Soviet Union, Russia began developing the
Kord heavy machine gun to replace the NSV "Utyos" and which entered service in 1998. The Metallist factory in what is now
