MG 42 - Maschinengewehr 42

The MG 42 or Maschinengewehr 42 (translated in English as Machine Gun 42) is a 7.92mm General Purpose machine gun that was developed from the MG39.

In 1937 HWaA (xxxx) issued a request for the design and manufacture or a new universal machine gun. Three companies received development contracts – Johannes Grossfuss AG, Stubgen AG and Rheinmetall-Borsig AG.

After a two year design and development period, the commission selected the prototype made by Grossfuss AG, designed by Ernst Gruner and Horn. This new machine gun, labeled as the MG 39 was made with a stamped steel construction as requested by the commission and was much easier to build and used less resources than the earlier MG34.

The manufacturing time for the MG42 was 50% faster taking only 75 man hours to complete the weapon as opposed to 150 hours for the MG34. Production costs where also improved by 24% by reducing the cost to 250 RM from the MG34's cost of 327 RM per unit. The new machine gun also required less raw materials than the MG 34, and it was simple to maintain and use.

In 1941 an initial production of 1500 MG 39/41 machine guns where taken to combat trials. The machine gun was made to lower tolerance of fit and finish and was found to be more reliable and rugged than its predecessor. With some improvements the Machine Gun was adopted and brought into service as the MG42

The MG42 was in general a great success, with its formidable rate of fire often quoted as between 1200 - 1500 rounds per minute. This rate of fire resulted in excessive consumption of ammunition and rapid overheating.

While the extremely rapid barrel change procedure allowed for sustained fire, the resulting accuracy suffered; excessive vibration from recoil, combined with a short sight radius, resulted in poor long range accuracy compared with earlier MG 34 and,especially, the heavy MG 08 Maxim guns.

Taking all into consideration, the MG 42 was an impressive and fearsome weapon, known among Allied soldiers as “Hitler’s buzz saw”,due to the sound of the firing which resembled the sound and a similar frequency of a mechanical saw.

At the end of WW2 this weapon, unlike other wartime designs, continued in service and lives on today as the MG 3 and its design features appear in the M60
