The NSV (Russian НСВ Никитина-Соколова-Волкова) is a 12.7mm caliber heavy machine gun of Soviet origin, named after the designers, G. I. Nikitin (Г. И. Никитин), Y. S. Sokolov (Ю. М. Соколов) and V. I. Volkov (В. И. Волков). It was designed to replace the DShK machine gun and was adopted by the Soviet Army in 1971. It is no longer being produced in Russia; the manufacturing license for the NSV ended up in Kazakhstan after the break-up of the Soviet Union. The NSV has been manufactured in Bulgaria, India, Poland and Yugoslavia under license.

The NSV weighs 25 kg (55 lb), has a rate of fire of 700-800 rounds per minute, and an effective range from 1,500 m (1,600 yd) to 2,000 m (2,200 yd) against airborne and ground targets, respectively. A loaded ammunition belt with 50 rounds weighs 11 kg (24 lb).

The NSVT version is used on the T-72, T-64 and T-80 tanks.

The new Kord machine gun has replaced worn-out NSVs.

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.

Testing approved Mikhail Kalashnikov's solution; 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 developed into the heavy NSV machine gun about 10 years later and selected in 1969 as the successor to the DShK/DShKM machine gun. It was accepted in service by the Soviet Army in 1971. The machine gun was also license-manufactured in Bulgaria, India, Yugoslavia and Poland. The Yugoslavian version of the NSVT is called the M87.
