History

When World War II started, the Soviet military only had the water-cooled Maxim M1910 machine gun at hand as their heavy machine gun.[1] ​So in 1942, a request was put out for new heavy machine gun for a rifle-calibre cartridge that can be fired in a ground, vehicle, or anti-aircraft mount. The machine gun was also to be able to take either the older canvas belts or the new disintegrating link belts.[2]

Development of the machine gun proper started in May 1942 by a team led by P.M.Goryunov. The weapon was sent for trials by May 1943 and was then adopted as the "7.62mm mounted machine gun system Goryunov", or SG-43 for short. The SG-43 was used as such in World War II, mainly with a ground mount that was wheeled and could mount a shield, though there were vehicle mounts as well.[1][2]

After World War II, the SG-43 was modernized into the SGM. The SGM modernization featured a longitudinally fluted barrel for weight saving and cooling.[2] The modernization also implemented a barrel lock that allowed for headspace adjustment. This modernized machine gun was developed into a tank mount as the SGMT, which had a solenoid trigger mounted on its back, and the SGMB, which had special mountings for use on an armored personnel carrier. Some manners of the modernization also were implemented onto the SG-43, such as a dust cover, and these weapons were designated as the SG-43M.[3]

The SGM and its family of weapons continued to see use in the Soviet military until the 1960s, when the PK machine guns began replacing the SGM due to its role as the Soviet's universal machine gun.[2] However, the SGM was exported or produced among countries allied or friendly with the Soviets such as East Germany, Poland, Romania, Cuba, Egypt,[1] North Vietnam, and China (which also domestically produces the machine gun as Type 58).[4]
