MG 34
In 1929, German engineers tested a new recoil-operated air-cooled machine gun that would eventually become the MG 34. This weapon emerged from a pre-World War I desire to replace heavy water-cooled guns with versatile alternatives. The Reichswehrministerium ordered Rheinmetall and other companies in 1932 to develop an Einheitsmaschinengewehr concept. Louis Stange led development at Rheinmetall's Sömmerda office using his earlier MG 30 design as a foundation. Heinrich Vollmer of Mauser Industries modified the feed mechanism to accept Patronentrommel 34 spring-loaded saddle-drum magazines. These early prototypes required special tools to optimize spring tension for reliable feeding. Users were explicitly ordered not to adjust drum spring tension themselves. By 1937, the feed system shifted to reusable non-disintegrating Gurt 33 and Gurt 34 metal belts. A 50-round Gurttrommel belt drum was introduced alongside these changes. Before large-scale production began, 2,300 units of two main early versions existed between 1935 and 1939. These first weapons included a cadence regulator device located in the grip to change firing rates. Louis Stange received patent number 686 843 for this feature at the end of 1939.
The Waffenamt realized by 1937 that the MG 34 Einheitsmaschinengewehr was too complex and expensive to mass-produce efficiently. Its elaborately milled precision engineering demanded tight tolerances and high-quality metal alloys. This resulted in high machine time requirements and extensive skilled labor needs. Production costs remained prohibitively high compared to simpler alternatives. During World War II, total MG 34 production reached over 350,000 units across multiple years. Specific annual figures show 12,822 units made in 1939, rising to 54,826 in 1940, then peaking at 80,952 in 1941. Subsequent years saw declining output: 63,163 in 1942, 48,802 in 1943, 61,396 in 1944, and finally 20,297 in 1945. Attempts to incrementally improve the fundamental design drawbacks failed repeatedly. The German military instead adopted mass production techniques similar to those used for the MP 40 submachine gun when creating the MG 42 successor. In 1943, MG 42 production surpassed MG 34 production and continued doing so until war's end. Despite this shift, Germans maintained widespread parallel production of MG 34s throughout the conflict.
A standard German infantry Gruppe squad consisted of ten men including a non-commissioned officer squad leader and deputy. Three-man machine gun teams operated each weapon with an assistant gunner loader and ammunition carrier. Five riflemen provided security covering fire while carrying additional ammunition hand grenades or explosive charges. Each full Gruppe carried 1,800 rounds of ammunition specifically allocated for their machine gun. American and British forces trained troops to take cover during brief barrel replacement windows when firing stopped. The German military instructed crews to avoid sustained cyclic rate fire at all costs. Optimal effectiveness came from firing short bursts of 7 to 10 rounds with approximately 15 bursts per minute. For medium machine gun roles using the Lafette 34 tripod, crews fired bursts of 20 to 50 rounds while optimizing aim between successive shots. Practical effective rate of fire reached only 150 rounds per minute due to reloading aiming and barrel changing times. An optimum operating crew in medium role required six men: squad leader machine gunner assistant gunner loader plus three riflemen carrying spare barrels entrenching tools and other equipment. Optical sights could be added via Zielfernrohrhalter brackets enabling indirect fire methods developed during World War I.
The MG 34 served as primary infantry machine gun throughout World War II despite never fully replacing older models like the MG 13. It remained standard armament for the Kriegsmarine German Navy and functioned as secondary weapon on most German tanks and armored vehicles. Captured weapons reached Chinese Nationalist Communist forces during both World War II and subsequent civil war periods. French armies sent captured units to Indochina during their colonial conflicts. Soviet captures and Czechoslovakian post-war manufacturing supplied People's Liberation Army and Viet Cong forces during Cold War engagements. Several hundred additional units originated from Western nations fighting colonial wars or anti-communist conflicts. Norway converted original designs to .30-06 Springfield caliber designated MG34F1 then later to 7.62×51mm NATO as MG34F2. These modified versions served Norwegian Home Guard until mid-1990s. Greece maintained operational stocks through 2023 according to Hellenic National Defence General Staff reports. Yugoslavia received 1,000 units in 1954 directly from Czechoslovakia. Korean War participants utilized captured examples extensively. Palestinian Fedayeen groups employed battlefield-captured weapons around 1985. SWAPO forces lost approximately 1,000 units near that same timeframe.
The MG 34 fired from an open bolt keeping the barrel open after firing ceased allowing airflow cooling. A rotating bolt operated by short recoil aided by muzzle booster unlocked via rotating lugs when barrel moved backward. Spent cartridge cases ejected downward through spring-loaded dust covers located just front of trigger group. Double-crescent triggers provided select fire capability without separate mode switches. Pressing upper segment produced semi-automatic fire while holding lower segment enabled fully automatic discharge. Service life expectancy reached about 6,000 rounds assuming regulations prohibiting rapid sustained fire beyond 250 rounds were followed. Emergency situations allowed limited rapid rates up to 400 rounds per barrel change cycle. Barrel changes took only 10 to 15 seconds when performed by well-trained crews using protective asbestos mitts. Entire receiver section pivoted right on latitudinal axis during replacement process. Standard iron sight lines featured notched V rear sights mounted posts single blade fronts calibrated meter increments. Spider web-type anti-aircraft sights enabled low-level defense roles. Active infrared devices paired Fahr- und Zielgerät FG 1250 driving aiming units with Sd.Kfz. 251/1 Falke half-tracks for night operations.
Prototype weapons like the MG 34S developed shortened lightened barrels stiffer multi-strand recoil springs better boosters increasing cyclic firing rates. Further improved models designated MG 34/41 could cope with 1,200 rounds per minute but components became highly stressed under combat conditions. Development efforts discontinued due to durability problems observed during Russian front trials. German military preferred technically fundamentally differing MG 39/41 gun instead of incremental improvements. Early 1942 saw official acceptance of further improved model officially designated MG 42. Most tanks and armored vehicles used MG 34 Panzerlauf or MG 34 Panzermantel secondary armament except Jagdpanzer IV tank destroyers. MG 42 barrel removal required sliding angled replacement compromising armor space when mounted inside vehicles. MG 34 remained favored because simpler in-line swapping mechanisms fit existing mountings easily. About 50,000 MG 34 Panzerlauf units produced featuring heavier almost solid Panzermantel armored barrel shrouds lacking ventilation holes. Bipod clamps attached standard bipods while anti-aircraft sight brackets removed entirely. Detachable butt stocks reduced space occupation inside generally limited vehicle interiors. Conversion kits carried quick ground use capabilities containing combined bipod front sight assemblies. Aircraft-mounted derivatives called MG 81 modified breeches allowing feeds from either side. Two guns bolted together formed MG 81Z twin configurations for flexible mounting purposes.
