How the StG 44 Revolutionized Modern Assault Rifles Forever

The Sturmgewehr 44 (StG 44) remains one of the most influential infantry weapons in history. Developed during World War II, its design and production marked a turning point for automatic firearms. A preserved prototype, seized by US forces in 1945, later ended up in an American military museum after minimal recorded testing.

The weapon's origins trace back to 1938, when Haenel received a contract to create a 7.92 mm selective-fire rifle. Polte Armaturen simultaneously worked on a shorter 7.92×33 mm cartridge to match it. By January 1942, Haenel's schwere Maschinenpistole 42 (heavy submachine gun 42) was sent to Polte for ammunition trials.

The project saw fierce competition between Haenel's *Mkb 42(H)* and Walther's *Mkb 42(W)*. Military evaluators at Döberitz preferred Haenel's model for its durability and simpler disassembly. Over time, the weapon's name shifted from *Maschinenkarabiner* to *Maschinenpistole* before settling on *Sturmgewehr 44*. Production surged as the war intensified. Factories churned out variants like the MP 43, MP 43/1, and MP 44, with monthly output sometimes surpassing 50,000 rifles by mid-1944. Hugo Schmeisser, Haenel's lead designer, oversaw further refinements, including the *StG 45(H)* prototype. This version featured a hinged receiver for easier maintenance, a streamlined gas piston, and a smooth gas tube compatible with rifle grenades. As Germany's resources dwindled, the StG 45(H) was designed to cut costs in materials and labour. One of the last prototypes, captured at Haenel on April 3, 1945, was shipped to the US for evaluation. It arrived at the Aberdeen Proving Ground in Maryland but saw no documented firing tests before being transferred to the Springfield Armory National Historic Site.

The StG 44's rapid development and mass production set new standards for assault rifles. Its influence extended beyond World War II, shaping future firearm designs worldwide. The preserved StG 45 prototype now serves as a tangible link to this pivotal chapter in military technology.
