161-546: The MG 42 (shortened from German: Maschinengewehr 42 , or "machine gun 42") is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II . Entering production in 1942, it was intended to supplement and replace the earlier MG 34 , which was more expensive and took much longer to produce, but both weapons were produced until
322-489: A Richt- und Überschießtafel (Overhead firing table) riveted to the rear body of the searchfire mechanism from the very start of production until the very end of it. In the later stages of World War II ballistic correction directions were added for overshooting friendly forces with S.m.E. - Spitzgeschoß mit Eisenkern (spitzer with iron core) ammunition of which the external ballistic behaviour started to significantly deviate from 1,500 m (1,640 yd) upwards compared to
483-556: A co-axial machine gun controlled by the gunner. It was improved in 1943 producing the DPM, but it was replaced in 1946 with the RP-46 which improved on the basic DP design by converting it to use belt feed. The DP machine gun was supplemented in the 1950s by the more modern RPD machine gun and entirely replaced in Soviet service by the general purpose PK machine gun in the 1960s. The DP-27

The government controlled artistic expression, promoting specific art forms and banning or discouraging others. Genocide , mass murder , and large-scale forced labour became hallmarks of the regime; the implementation of the regime's racial policies culminated in the Holocaust . After the initial success of German invasion of

966-590: A bipod for firing from prone positions, and the previously mentioned pan magazine. In total, the first versions contained only 80 parts, indicating both the simplicity and ease of manufacture of the design. Early versions had 26 transverse cooling fins machined into the barrel, but it was found that these had little cooling effect and so were deleted in 1938, further easing manufacture. The design had weaknesses that would eventually be addressed in later variants. The pan magazines were prone to damage, while also being difficult and time-consuming to reload. The bipod mechanism
1127-488: A communist uprising. The Reichstag Fire Decree , imposed on 28 February 1933, rescinded most civil liberties, including rights of assembly and freedom of the press. The decree also allowed the police to detain people indefinitely without charges. The legislation was accompanied by a propaganda campaign that led to public support for the measure. Violent suppression of communists by the SA was undertaken nationwide and 4,000 members of

The (slower) rapid firing rate used in emergency/final defensive line situations of the MG 42 was up to 500 rounds per minute. The Allied nations had machine guns with similar rates of fire, but mounted them almost exclusively in aircraft, where
1449-580: A massive secret rearmament program , forming the Wehrmacht (armed forces). The return to economic stability boosted the regime's popularity. Germany made increasingly aggressive territorial demands, threatening war if they were not met. Germany seized Austria in the Anschluss of 1938, and demanded and received the Sudetenland region of Czechoslovakia. Germany signed a non-aggression pact with
1610-443: A minute were most effective. For its medium machine gun role, the MG 42 was matched to the newly developed Lafette 42 tripod. In the tripod-mounted medium machine gun role, MG 42 users were trained to fire short bursts and bursts of 20 to 50 rounds and strive to optimize their aim between bursts fired in succession. As a consequence of factors like the time spent reloading, aiming, changing hot barrels if necessary to allow for cooling,
1771-657: A non-aggression pact with Poland. In March 1939, Hitler demanded the return of the Free City of Danzig and the Polish Corridor , a strip of land that separated East Prussia from the rest of Germany. The British announced they would come to the aid of Poland if it was attacked. Hitler, believing the British would not take action, ordered an invasion plan should be readied for September 1939. On 23 May, Hitler described to his generals his overall plan of not only seizing

As personal small arms, the squad leader was issued a rifle , or as of around 1941 a submachine gun , the machine gunner and his assistant were issued pistols and the deputy squad leader, ammunition carrier and
2093-490: A predefined area. The length of the beaten zone could be set on the Tiefenfeuerautomat . E.g., being unsure whether the real distance was 2,000 or 2,300 m (2,187 or 2,515 yd), the gunner could make the mount do an automatic sweep between the elevations for 1,900 to 2,400 m (2,078 to 2,625 yd) and back. This sweeping of a selected beaten zone continued as long as the gun fired. The Lafette 42 had

An active infrared device, intended primarily for night use, and consisting of
2576-459: A second national anthem. Germany was still in a dire economic situation, as six million people were unemployed and the balance of trade deficit was daunting. Using deficit spending , public works projects were undertaken beginning in 1934, creating 1.7 million new jobs by the end of that year alone. Average wages began to rise. The SA leadership continued to apply pressure for greater political and military power. In response, Hitler used
2737-526: A specialized mount, active 300 millimeters (11.8 in) infrared spotlight and accompanying infrared image converter was developed that could be used with the MG 42 and MG 34. In the later stages of World War II the bulky Fahr- und Zielgerät FG 1250 (driving and aiming device FG 1250 ) active infrared unit was paired on Sd.Kfz. 251/1 Falke half-track armored personnel carriers to some MG 42 and MG 34 machine guns. The MG 42 could use non-disintegrating metallic-link belts , which have links that wrap around
2898-713: A substantial minority of Germans, who lived mostly in the Sudetenland . Under pressure from separatist groups within the Sudeten German Party , the Czechoslovak government offered economic concessions to the region. Hitler decided not just to incorporate the Sudetenland into the Reich, but to destroy the country of Czechoslovakia entirely. The Nazis undertook a propaganda campaign to try to generate support for an invasion. Top German military leaders opposed
3059-626: A thousand people (out of a population of around 16,000) committed suicide in Demmin around 1 May 1945 as the 65th Army of 2nd Belorussian Front first broke into a distillery and then rampaged through the town, committing mass rapes, arbitrarily executing civilians, and setting fire to buildings. High numbers of suicides took place in many other locations, including Neubrandenburg (600 dead), Stolp in Pommern (1,000 dead), and Berlin, where at least 7,057 people committed suicide in 1945.

3381-896: A war fought on two fronts. The invasion conquered a huge area, including the Baltic states, Belarus , and west Ukraine . After the successful Battle of Smolensk in September 1941, Hitler ordered Army Group Centre to halt its advance to Moscow and temporarily divert its Panzer groups to aid in the encirclement of Leningrad and Kyiv . This pause provided the Red Army with an opportunity to mobilise fresh reserves. The Moscow offensive, which resumed in October 1941, ended disastrously in December . On 7 December 1941, Japan attacked Pearl Harbor , Hawaii. Four days later, Germany declared war on

The Saarland , which had been placed under League of Nations supervision for 15 years at the end of World War I, voted in January 1935 to become part of Germany. In March 1935, Hitler announced the creation of an air force, and that the Reichswehr would be increased to 550,000 men. Britain agreed to Germany building a naval fleet with the signing of
3703-632: Is a light machine gun designed for the Soviet Red Army in the 1920s under the leadership of Vasily Degtyaryov (1880–1949), the first test model being the DP-26. Two test guns were manufactured and fired 5,000 rounds each from September 27–29, 1926, during which weaknesses were discovered in the extractor and firing pin mechanisms. After design improvements, two more guns were made and tested in December 1926, firing 40,000 rounds under adverse conditions, resulting in only .6% stoppages. However, changes to
3864-428: Is advantageous for use against targets that are exposed to a general-purpose machine gun for a limited time span, like aircraft or targets that minimize their exposure time by quickly moving from cover to cover. For targets that can be fired on by a general-purpose machine gun for longer periods than just a few seconds, the cyclic firing rate becomes less important. As a consequence, one of the MG 42's most notable features
4025-452: Is considered to be the first modern general-purpose machine gun or Einheitsmaschinengewehr . It was developed to use the standard German 7.92×57mm Mauser full-power rifle round. It was envisaged and well developed to provide portable light and medium machine gun infantry cover, low level anti-aircraft coverage, and even sniping ability. Equipped with a quick-change barrel and fed either with non-disintegrating metallic-link belts , or from

Another unique feature of German World War II machine guns was the Tiefenfeuerautomat feature on the Lafette 42 and Lafette 34 tripods. It lengthened the beaten zone by walking the fire in wave-like motions up and down the range in

Hitler targeted SA Stabschef (Chief of Staff) Ernst Röhm and other SA leaders who—along with a number of Hitler's political adversaries (such as Gregor Strasser and former chancellor Kurt von Schleicher )—were arrested and shot. Up to 200 people were killed from 30 June to 2 July 1934 in an event that became known as
4508-579: The Völkisch movement . The party, especially its paramilitary organisation Sturmabteilung (SA; Storm Detachment), or Brownshirts, used physical violence to advance their political position, disrupting the meetings of rival organisations and attacking their members as well as Jewish people on the streets. Such far-right armed groups were common in Bavaria , and were tolerated by the sympathetic far-right state government of Gustav Ritter von Kahr . When
4669-541: The 6th Army could be supplied by air, but this turned out to be infeasible. Hitler's refusal to allow a retreat led to the deaths of 200,000 German and Romanian soldiers; of the 91,000 men who surrendered in the city on 31 January 1943, only 6,000 survivors returned to Germany after the war. Losses continued to mount after Stalingrad, leading to a sharp reduction in the popularity of the Nazi Party and deteriorating morale. Soviet forces continued to push westward after

Besides being the standard Soviet infantry light machine gun (LMG) during World War II , with various modifications it was used in aircraft as a flexible defensive weapon, and it equipped almost all Soviet tanks in WWII as either a flexible bow machine gun or
4991-745: The Anglo-German Naval Agreement on 18 June 1935. When the Italian invasion of Ethiopia led to only mild protests by the British and French governments, on 7 March 1936 Hitler used the Franco-Soviet Treaty of Mutual Assistance as a pretext to order the army to march 3,000 troops into the demilitarised zone in the Rhineland in violation of the Versailles Treaty. As the territory was part of Germany,

The MG 34 was also quite versatile; not only was it able to be fed from belted ammunition or a saddle drum magazine, it could also be fired from a bipod, an innovative Lafette 34 tripod or various pintle mounts for armored vehicles. Switching between a bipod and a tripod required no special tools, as
5635-738: The Communist Party of Germany were arrested. On 23 March 1933, the Enabling Act , an amendment to the Weimar Constitution , passed in the Reichstag by a vote of 444 to 94. This amendment allowed Hitler and his cabinet to pass laws—even laws that violated the constitution—without the consent of the president or the Reichstag. As the bill required a two-thirds majority to pass, the Nazis used intimidation tactics as well as

5957-633: The German Empire (1871–1918) as the second. Severe setbacks to the German economy began after World War I ended, partly because of reparations payments required under the 1919 Treaty of Versailles . The government printed money to make the payments and to repay the country's war debt, but the resulting hyperinflation led to inflated prices, economic chaos, and food riots. When the government defaulted on their reparations payments in January 1923, French troops occupied German industrial areas along
6118-489: The Gurt 34 links were made of 0.7 mm (0.028 in) and Gurt 34/41 links of 0.5 mm (0.020 in) thick stamped steel sheet metal — that saved ⅓ of metal and counterintuitively yielded improved performance. Belts were supplied in a fixed length of 50 rounds, but could be linked up to make longer belts for sustained firing. Ammunition boxes contained 250 rounds in five 50-round belts.

Hindenburg died on 2 August 1934, and Hitler became dictator by merging the powers of the chancellery and presidency. A 1934 German referendum confirmed Hitler as sole Führer (leader). Power was centralised in Hitler's person, and his word became
11431-402: The RAF in what became known as the Battle of Britain , and by the end of October, Hitler realised that air superiority would not be achieved. He permanently postponed the invasion, a plan which the commanders of the German army had never taken entirely seriously. Several historians, including Andrew Gordon , believe the primary reason for the failure of the invasion plan was the superiority of
11592-882: The Royal Navy, not the actions of the RAF. In February 1941, the German Afrika Korps arrived in Libya to aid the Italians in the North African Campaign . On 6 April, Germany launched an invasion of Yugoslavia and Greece . All of Yugoslavia and parts of Greece were subsequently divided between Germany, Hungary, Italy, and Bulgaria. On 22 June 1941, contravening the Molotov–Ribbentrop Pact, about 3.8 million Axis troops attacked
11753-537: The Soviet Union . Germany annexed parts of northern Yugoslavia in April 1941, while Mussolini ceded Trieste , South Tyrol , and Istria to Germany in 1943. Degtyaryov machine gun The Degtyaryov machine gun ( Russian : Пулемёт Дегтярёвa Пехотный , romanized : Pulemyot Degtyaryova Pekhotny literally: "Degtyaryov's infantry machine gun") or DP-27/DP-28 is a light machine gun firing
11914-664: The Soviet Union a non-aggression pact, the Molotov–Ribbentrop Pact , signed in August 1939. The treaty also contained secret protocols dividing Poland and the Baltic states into German and Soviet spheres of influence. Germany's wartime foreign policy involved the creation of allied governments controlled directly or indirectly from Berlin. They intended to obtain soldiers from allies such as Italy and Hungary and workers and food supplies from allies such as Vichy France . Hungary
12075-573: The Soviet Union attacked from the east on 17 September. Reinhard Heydrich , chief of the Sicherheitspolizei (SiPo; Security Police) and Sicherheitsdienst (SD; Security Service), ordered on 21 September that Polish Jews should be rounded up and concentrated into cities with good rail links. Initially the intention was to deport them further east, or possibly to Madagascar . Using lists prepared in advance , some 65,000 Polish intelligentsia, noblemen, clergy, and teachers were murdered by
12236-722: The Soviet Union in 1941, Nazi Germany attempted to implement the Generalplan Ost and Hunger Plan , as part of its war of extermination in Eastern Europe. The Soviet resurgence and entry of the US into the war meant Germany lost the initiative in 1943 and by late 1944 had been pushed back to the 1939 border. Large-scale aerial bombing of Germany escalated and the Axis powers were driven back in Eastern and Southern Europe. Germany
12397-498: The Soviet Union. In addition to Hitler's stated purpose of acquiring Lebensraum , this large-scale offensive—codenamed Operation Barbarossa —was intended to destroy the Soviet Union and seize its natural resources for subsequent aggression against the Western powers. The reaction among Germans was one of surprise and trepidation as many were concerned about how much longer the war would continue or suspected that Germany could not win
12558-545: The United States. Food was in short supply in the conquered areas of the Soviet Union and Poland, as the retreating armies had burned the crops in some areas, and much of the remainder was sent back to the Reich. In Germany, rations were cut in 1942. In his role as Plenipotentiary of the Four Year Plan , Hermann Göring demanded increased shipments of grain from France and fish from Norway. The 1942 harvest
12719-562: The Weimar Republic, rejection of the Treaty of Versailles, radical antisemitism , and anti- Bolshevism . They promised a strong central government, increased Lebensraum ("living space") for Germanic peoples, formation of a national community based on race, and racial cleansing via the active suppression of Jews , who would be stripped of their citizenship and civil rights. The Nazis proposed national and cultural renewal based upon
12880-758: The adoption of the final MG 34 production version, the Waffenamt (German Army Weapons Agency) realized the MG 34 Einheitsmaschinengewehr was too complex and expensive to mass-produce and started looking for ways to simplify and rationalize the technical concept. A draft specification was made and a contest was held for an MG 34 replacement. Three companies were asked in February 1937 to submit designs: Metall und Lackierwarenfabrik Johannes Großfuß AG of Döbeln , Rheinmetall-Borsig AG of Sömmerda , and Stübgen AG of Erfurt . The design and mock-up gun proposals were submitted in October 1937. Großfuß AG's entry proved to be
13041-595: The barrel unit of the MG 42. It could be quickly changed by the machine gun crew and weighed 1.75 kg (3.9 lb) including the locking piece. The barrels could have traditional rifling or polygonal rifling . Polygonal rifling was an outgrowth of a cold-hammer forging process developed by German engineers before World War II. The process addressed the need to produce more durable machine gun barrels in less time than those produced with traditional methods. Later produced barrel bores featured hard-chrome plating to make them more durable. The different versions meant that
13202-451: The best design by far, employing a unique recoil-operated roller locking mechanism whereas the two competing entries used a gas-actuated system. The Großfuß company had no earlier experience in weapons manufacture, specializing in pressed and stamped steel components (the company's staple product was sheet metal lanterns ). Dr.-Ing. Werner Gruner , one of the leading design engineers with Großfuß, knew nothing about machine guns when he
13363-500: The blockade, imports into Germany declined by 80 per cent. To safeguard Swedish iron ore shipments to Germany, Hitler ordered the invasion of Denmark and Norway , which began on 9 April. Denmark fell after less than a day , while most of Norway followed by the end of the month. By early June, Germany occupied all of Norway . Against the advice of many of his senior military officers, in May 1940 Hitler ordered an attack on France and
13524-410: The bolt assembly into battery (the locked position) and returning it there when it is unlocked and pushed backwards by the recoil of firing or by the charging handle. As the striker sleeve is movable back and forth within the bolt assembly, the return spring is also responsible for pushing the striker sleeve forward during locking (described below). The bolt assembly locks with the barrel's breech (the end
13685-524: The bolt carrier and the chamber locking mechanism were still required. After this redesign the improved gun, now called the DP-27, was tested by the Red Army at the Kovrov plant on January 17–21 of 1927, passing all tests and being approved for manufacture. A full year of service testing followed, after which the primary requested change was the addition of the large flash suppressor that is now considered one of
13846-413: The bolt head and allowing the bolt assembly to further recoil rearwards, extracting the spent cartridge case and ejecting it downwards through an ejection port normally covered by a spring-loaded dust cover at the bottom of the receiver, just in front of the trigger group. The spring-loaded dust cover automatically opens when the gun is fired, but the user has to close it after firing to prevent dirt entering
14007-464: The business community, President Paul von Hindenburg appointed Hitler as Chancellor of Germany on 30 January 1933. This event is known as the Machtergreifung ("seizure of power"). On the night of 27 February 1933, the Reichstag building was set afire . Marinus van der Lubbe , a Dutch communist, was found guilty of starting the blaze. Hitler proclaimed that the arson marked the start of
14168-414: The cartridge case and are linked by a coiling wire on each side. The belts are intended for multiple reuse. As in the MG 34, operation through the feed block is by a feed arm housed in the feed cover. The feeding system was based on the direct push-through of the cartridge out of the belt link into the gun's chamber. Accordingly, the link had to be of the half-open type to enable the motion of the bolt through
14329-402: The cartridge is loaded into) via a prong type barrel extension behind the breech. As it is recoil-operated and fired from an open bolt, the weapon must be manually charged with the side-mounted charging handle. The roller-locked recoil operation functions as follows: two cylindrical rollers, positioned in tracks on the bolt head, are pushed outwards into matching tracks in the barrel extension by
14490-513: The churches. The Nazi regime abolished the symbols of the Weimar Republic—including the black, red, and gold tricolour flag —and adopted reworked symbolism. The previous imperial black, white, and red tricolour was restored as one of Germany's two official flags; the second was the swastika flag of the Nazi Party, which became the sole national flag in September 1935. The Party anthem " Horst-Wessel-Lied " ("Horst Wessel Song") became
14651-553: The city of Spandau where some were produced. Brazilian expeditionary soldiers fighting in Italy used to refer to the MG 42 as Lurdinha ; this nickname is due to the fact that the bride of one of the soldiers, named Maria de Lourdes, was a seamstress and the sound of MG 42 was similar to the sound of her sewing machine ( Lourdinha is a common nickname in Brazil for women called Maria de Lourdes). The German tactical infantry doctrine of
14812-551: The country; all trade unions were forced to dissolve and their leaders were arrested. The Law for the Restoration of the Professional Civil Service , passed in April, removed from their jobs all teachers, professors, judges, magistrates, and government officials who were Jewish or whose commitment to the party was suspect. This meant the only non-political institutions not under control of the Nazis were
14973-438: The cyclic rate of the machine gun. Heavy bolts also were used along with stiffer return springs . The standard MG 42 bolt weight for a 1,500 rounds per minute cyclic rate of fire is 505 g (17.81 oz). The open-type iron sighting line has a relatively short 430 millimeters (16.9 in) radius and consists of a "∧-type" height adjustable front sight on a folding post and a leaf rear sight with an open V-notch sliding on
15134-563: The design used in the M60 machine gun . The trigger mechanism of the FN MAG or MAG-58 is a virtual copy of the MG 42's, and the FN MAG's belt-feed mechanism is also very similar. The roller-locked bolt assembly consists of a bolt head, two rollers, a striker sleeve featuring a wedge-shaped front, bolt body, and a large multi strands around a central coil return spring, which is responsible for pushing
15295-410: The early stages of the war. Being made largely out of pressed and stamped appropriately hardened carbon steel metal, only the most important parts were elaborately milled from solid steel, and using spot welding and riveting to connect parts the new design required considerably less machining and fewer high grade steel alloys containing metals that became scarce in Germany during World War II. It
15456-563: The electorate in a plebiscite . Most Germans were relieved that the conflicts and street fighting of the Weimar era had ended. They were deluged with propaganda orchestrated by Minister of Public Enlightenment and Propaganda Joseph Goebbels , who promised peace and plenty for all in a united, Marxist-free country without the constraints of the Versailles Treaty. The Nazi Party obtained and legitimised power through its initial revolutionary activities, then through manipulation of legal mechanisms,
15617-471: The end of 1939 in an attempt to destroy Poland's identity as a nation. Soviet forces advanced into Finland in the Winter War , and German forces saw action at sea. But little other activity occurred until May, so the period became known as the " Phoney War ". From the start of the war, a British blockade on shipments to Germany affected its economy. Germany was particularly dependent on foreign supplies of oil, coal, and grain. Thanks to trade embargoes and
15778-441: The end of World War II. Designed to use the standard German fully-powered 7.92×57mm Mauser rifle round and to be cheaper and easier to manufacture, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges: it averaged about 1,200 rounds per minute, compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like
15939-500: The end of the war. The Germans nevertheless continued widespread production of MG 34s in parallel until the end of the war. The distinctive sound caused by the high cyclic firing rate gave rise to a variety of nicknames. The Germans called it the Hitlersäge ( Hitler 's Buzzsaw), Schnelle Spritze (Fast Sprayer), Knochensäge (Bone Saw), Tripperspritze (Gonorrhoea Syringe) and elektrisches MG (Electric MG). The Soviets called it
16100-417: The era based a (10-man Gruppe ) squad 's firepower on the general-purpose machine gun in the light machine gun role. The advantage of the general-purpose machine gun concept was that it added greatly to the overall volume of fire that could be put out by a squad-sized unit. It was possible for operating crews to lay down a non-stop barrage of fire, pausing only when the barrel had to be replaced. This allowed
16261-602: The establishment of the Nuremberg Laws of 1935, which stripped them of their basic rights. The Nazis would take from the Jews their wealth, their right to intermarry with non-Jews, and their right to occupy many fields of labour (such as law, medicine, or education). Eventually the Nazis declared the Jews as undesirable to remain among German citizens and society. As early as February 1933, Hitler announced that rearmament must begin, albeit clandestinely at first, as to do so
16422-541: The exception of the Jagdpanzer IV . Early versions of the Jagdpanzer IV carried two standard (no modification made) MG 42s on both sides of the main gun mantlet/glacis, firing through a firing port which was protected by an armored cover plate; the MG 42s were retracted when not in use. Later version Jagdpanzer IVs carried only one MG 42 as internal secondary armament. The MG 42 belt-feed mechanism inspired
16583-473: The execution of more than 4,900 people. The failed Ardennes Offensive (16 December 1944 – 25 January 1945) was the last major German offensive on the western front, and Soviet forces entered Germany on 27 January. Hitler's refusal to admit defeat and his insistence that the war be fought to the last man led to unnecessary death and destruction in the war's closing months. Through his Justice Minister Otto Georg Thierack , Hitler ordered that anyone who
16744-1126: The failed German offensive at the Battle of Kursk in the summer of 1943. By the end of 1943, the Germans had lost most of their eastern territorial gains. In Egypt, Field Marshal Erwin Rommel 's Afrika Korps were defeated by British forces under Field Marshal Bernard Montgomery in October 1942. The Allies landed in Sicily in July 1943 and were on the Italian peninsula by September. Meanwhile, American and British bomber fleets based in Britain began operations against Germany . Many sorties were intentionally given civilian targets in an effort to destroy German morale. The bombing of aircraft factories as well as Peenemünde Army Research Center , where V-1 and V-2 rockets were being developed and produced, were also deemed particularly important. German aircraft production could not keep pace with losses, and without air cover
16905-476: The feeding process by improved ammunition belt retention for more precise indexing with the feedway and reduces mechanical stress put on the feed unit and belt links. According to Infantry Journal in 1947, the operating momentum driven MG 42 feed system will not function reliably under a cyclic firing rate of 850 rounds per minute. During World War II the Gurt 34/41 -belt family was introduced. Gurt 34/41 belt links and wire spirals were made of thinner material —
17066-534: The fleeting opportunities for firing made such high rates necessary. The Allies did have similar weapons, such as the M1919 Browning machine gun and the Vickers K machine gun, but these were issued more sparsely than the MG 42, with the Vickers K being an aircraft machine gun, only issued to infantry in specialized circumstances. A German infantry Gruppe (squad) at the start of the war consisted of ten men;
17227-668: The future. Food supplies were precarious; production dropped in most of Europe. Famine was experienced in many occupied countries. Hitler's peace overtures to the new British Prime Minister Winston Churchill were rejected in July 1940. Grand Admiral Erich Raeder had advised Hitler in June that air superiority was a pre-condition for a successful invasion of Britain , so Hitler ordered a series of aerial attacks on Royal Air Force (RAF) airbases and radar stations, as well as nightly air raids on British cities, including London , Plymouth , and Coventry . The German Luftwaffe failed to defeat
17388-432: The gun operator would open a side hatch (leading to the barrel) and replace the hot barrel with a new cooler one. Non-observance of this technical limitation renders the barrel prematurely unusable. The machine gun crew member responsible for a hot barrel change was issued protective asbestos mitts to prevent burns to the hands. The German military instructed that sustained fire must be avoided at all costs. They ruled that
17549-492: The harmonics problem in the roller/wedge system and make the MG 42 less ammunition ignition timing sensitive was needed. The roller-locking system inherent problem was solved after World War II by developing and adding bolt-bounce preventing bolt catches to the action. These can also be retrofitted to MG 42 bolts. The cyclic firing rate of the MG 42 can be altered by installing different bolts and return springs. A heavier bolt uses more recoil energy to overcome inertia, thus slowing
17710-526: The highest law. The government was not a coordinated, cooperating body, but rather a collection of factions struggling to amass power. In the midst of the Great Depression , the Nazis restored economic stability and ended mass unemployment using heavy military spending. Financed by deficit spending , the regime undertook extensive public works projects, including the Autobahnen (motorways) and
17871-409: The late World War II MG Z 44, designed for direct fire only. Fitting such an optical sight enabled the machine gun to deliver direct fire out to 3,000 m (3,281 yd). An accessory to lengthen these sights' periscope was available to use these sights behind cover. The Lafette could be set up in a prone, kneeling or high position. The Lafette 42 weighed 20.5 kg (45.2 lb) on its own and
18032-444: The left side of the gun. It was not a true magazine but held a coiled 50-round belt and corresponding Einführstück starter-segment preventing it from snagging, twisting and getting stuck during mobile assaults. The Gurttrommel belt container was commonly used until the end of World War II, with the MG 42 and the earlier MG 34. The 530 millimeters (20.9 in) long barrel and its prong type barrel extension used for lock up, made up
18193-435: The light machine gun role with the bipod , lighter than the MG 34 and easily portable. The underfolding bipod, the same one used on the MG 34, could be mounted to the front near the muzzle to minimize shot dispersion or the center of the gun near the balance point offering more flexibility depending on how and where it was being used. The shoulder stock is designed to permit gripping with the left hand to hold it secure against
18354-407: The link. New in the MG 42 was that two belt feed pawls are linked to the front end of the feed arm by an intermediate link, in such a way that when one pawl is feeding, the other pawl is riding over the next round in the belt. Because of that, feed is performed in two steps, on both the opening and closing movement of the bolt, instead of one step as in the earlier MG 34. This enhances the smoothness of
18515-439: The machine gun contest board. The resulting Großfuß MG 39 prototype gun presented in February 1939 remained similar to the earlier MG 34 overall, a deliberate decision made to maintain familiarity and capability to use the various mounts and other accessories developed for the MG 34 to adapt the gun to different roles. The only major changes from the gunner's perspective were dropping of the saddle-drum-magazine feed option, leaving
18676-690: The mass-production model began, as the MG 42 , contracts going to Großfuß , Mauser-Werke , Gustloff-Werke , Steyr and others. The MG 42 was first deployed in May 1942 by the Deutsches Afrikakorps (German Africa Corps expeditionary force in Africa) and introduced by mid-1942 on all fronts. Production during the war amounted to over 400,000 units (17,915 units in 1942, 116,725 in 1943, 211,806 in 1944, and 61,877 in 1945). In 1943, MG 42 production surpassed MG 34 production and continued to do so until
18837-406: The mounting latch was spring-loaded. As the MG 34 Panzerlauf , it was used throughout the war as secondary armament on panzers and other vehicles. However, the MG 34 did have fundamental drawbacks, such as sensitivity to extreme weather conditions, dirt and mud, and comparatively complex and expensive production. Attempts to incrementally improve the basic MG 34 design failed. Between 1934 and
18998-478: The need for Germany to secure its frontiers. Schuschnigg scheduled a plebiscite regarding Austrian independence for 13 March, but Hitler sent an ultimatum to Schuschnigg on 11 March demanding that he hand over all power to the Austrian Nazi Party or face an invasion. German troops entered Austria the next day, to be greeted with enthusiasm by the populace. The Republic of Czechoslovakia was home to
19159-497: The plan, as Germany was not yet ready for war. The crisis led to war preparations by Britain, Czechoslovakia, and France (Czechoslovakia's ally). Attempting to avoid war, British Prime Minister Neville Chamberlain arranged a series of meetings, the result of which was the Munich Agreement , signed on 29 September 1938. The Czechoslovak government was forced to accept the Sudetenland's annexation into Germany. Chamberlain
19320-472: The precisely machined and somewhat temperamental MG 34. Further trials resulted in selecting the Großfuß MG 39 prototype gun for final production development. A limited run of about 1,500 of further improved MG 39/41 pre mass-production model guns, was completed in 1941 and by the end of 1941 tested in combat trials. In early 1942 the final model of the weapon was officially accepted, and manufacturing of
19481-606: The provisions of the Reichstag Fire Decree to keep several Social Democratic deputies from attending, and the Communists had already been banned. The Enabling Act would subsequently serve as the legal foundation for the dictatorship the Nazis established. On 10 May, the government seized the assets of the Social Democrats, and they were banned on 22 June. On 21 June, the SA raided the offices of
19642-424: The receiver through the open port. Simultaneously the barrel is pushed forward by a recuperator spring to its starting position. The three-wire braided return spring then pushes the bolt assembly forwards again, pushing a new cartridge out of the belt into the breech. The sequence repeats as long as the trigger is depressed. The original MG 42 roller-locked action had an undesirable tendency to exhibit bolt-bounce. It
19803-462: The recognition features of the design. With further refinements, the DP was to be the primary light machine gun of the Red Army during WWII. The DP-27 was designed to fire the same 7.62×54mmR ( R indicating rimmed ) ammunition as the main Soviet infantry rifle, the Mosin-Nagant , much simplifying ammunition logistics for Soviet infantry units. Of typical Russian design philosophy, the DP-27
19964-414: The recoil booster assembly ends in a muzzle shroud and also functions as a guide sleeve for the barrel and a muzzle flash arrester . As the barrel of the MG 42 is changed through the side of the barrel shroud, rather than directly from the rear as in the MG 34, this made the MG 42 unsuitable for use as internal secondary or co-axial armament on World War II era German tanks or other armored vehicles, with
20125-406: The results of sustained fire were disappointing and that the expenditure of ammunition involved was "intolerable." In the bipod-mounted light machine gun role, MG 42 users were trained to fire short bursts of 3 to 7 rounds and strive to optimize their aim between bursts fired in succession. According to comparative tests by the US military under battle conditions, 5 to 7 rounds bursts with 22 bursts in
20286-404: The riflemen were issued rifles. The riflemen carried additional ammunition, hand grenades , explosive charges or a machine gun tripod as required and provided security and covering fire for the machine gun team. Two of the standard issue bolt-action Karabiner 98k rifles in the squad could be replaced with semi-automatic Gewehr 43 rifles and occasionally, StG 44 assault rifles could be used to re-arm
20447-471: The rollers in the bolt were found to "bounce" back and forth or oscillate up to 1 mm (0.04 in) when lock up is proceeding and then they settle into full lock up. Once the problem was identified, the temporary solution was to design and manufacture extra sturdy ammunition with primers with a slightly slower ignition time which allowed the rollers to settle into lockup and issue that ammunition specifically for MG 42 use. A more practical solution to control
20608-426: The service life of an MG 42 barrel varied between 3,500 and 8,000 rounds assuming the barrel was used according to the regulations, which prohibited rapid fire beyond 150 rounds. Excessive overheating caused by rapid firing about 500 rounds through a barrel resulted in unacceptable wear of the bore rendering the barrel useless. For carrying and protecting spare barrel units, consisting of a barrel and its locking piece,
20769-603: The shoulder. The MG 42 incorporated lessons hard-won on the Eastern Front . Both the cocking handle and the catch for the top cover to the working parts were designed so that the gunner could operate them wearing arctic mittens or with a stick or rod. This was vital for winter conditions where contact by bare flesh on cold metal could cause severe injury, such as instant frostbite . The MG 42 also functioned well in other climates; dust and dirt in North Africa and Italy
20930-460: The stock market in the United States crashed in 1929 , the effect in Germany was dire. Millions were thrown out of work and several major banks collapsed. Hitler and the Nazis prepared to take advantage of the emergency to gain support for their party. They promised to strengthen the economy and provide jobs. Many voters decided the Nazi Party was capable of restoring order, quelling civil unrest, and improving Germany's international reputation. After
21091-412: The striker sleeve and lock the bolt in place against the breech. In the locked position during firing the rollers rest on parallel surfaces relative to the bore axis on the bolt head ensuring a full lockup. Upon firing, rearward force from the recoil of the cartridge ignition combined with the additional rearward force generated by the muzzle booster start to move the barrel and bolt assembly rearwards for
21252-407: The top of the receiver. Because of the shape of its magazine, the DP-27 was nicknamed the "record player". Its main parts were a removable barrel with an integrated flash suppressor and gas cylinder, a receiver with the rear sight, a perforated barrel shroud/guide with the front sight, the bolt and locking flaps, the bolt carrier and gas piston rod, a recoil spring, stock and trigger mechanism group,
21413-582: The total German war dead range from 5.5 to 6.9 million persons. A study by German historian Rüdiger Overmans puts the number of German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders. Richard Overy estimated in 2014 that about 353,000 civilians were killed in Allied air raids. Other civilian deaths include 300,000 Germans (including Jews) who were victims of Nazi political, racial, and religious persecution and 200,000 who were murdered in
21574-421: The use of police powers, and by taking control of the state and federal institutions. The first major Nazi concentration camp , initially for political prisoners, was opened at Dachau in 1933. Hundreds of camps of varying size and function were created by the end of the war. Beginning in April 1933, scores of measures defining the status of Jews and their rights were instituted. These measures culminated in
21735-494: The war drew to a close. Suicide rates in Germany increased, particularly in areas where the Red Army was advancing. Among soldiers and party personnel, suicide was often deemed an honourable and heroic alternative to surrender. First-hand accounts and propaganda about the uncivilised behaviour of the advancing Soviet troops caused panic among civilians on the Eastern Front, especially women, who feared being raped. More than
21896-450: The weapon could be used to devastating effect, it could quickly exhaust its ammunition supply. For this reason, it was not uncommon for all soldiers operating near an MG 42 to carry extra ammunition, thus providing the MG 42 with a backup source when its main supply was exhausted. Another disadvantage of the MG 42 was that the high cyclic rate of fire led to the barrel overheating quickly during rapid fire. After around 150 rounds of rapid fire,
22057-462: The weapon to fire belted ammunition , or from a single 50-round drum-shaped Gurttrommel belt container fitted to the gun's receiver, and simplifying the weapon's open sights for aiming purposes. All these changes were intended to increase, maintain, or accommodate the gun's high cyclic rate of fire and dispersion. Although made of relatively inexpensive and simple parts, the prototypes proved to be considerably more rugged and resistant to jamming than
22218-495: The whole squad, besides the machine gun. A full Gruppe (squad) carried 1,800 rounds of ammunition for the machine gun between them. In the German heavy machine gun (HMG) platoons , each platoon served four MG 34/MG 42 machine guns, used in the sustained fire mode mounted on tripods. In 1944, this was altered to six machine guns in three sections with two seven-man heavy machine gun squads per section as follows: The optimum operating crew of an MG 42 in its medium machine gun role
22379-494: Was a powerful ally, the relationship was distant, with little co-ordination or co-operation. For example, Germany refused to share their formula for synthetic oil from coal until late in the war. Germany invaded Poland and captured the Free City of Danzig on 1 September 1939, beginning World War II in Europe. Honouring their treaty obligations, Britain and France declared war on Germany two days later. Poland fell quickly, as
22540-430: Was a simplified version of the Lafette 34 used for the MG 34, as the MG 42 could be operated more easily from a Lafette and featured no semi-automatic firing mode. The legs could be extended with a Lafetteaufsatzstück to allow it to be used in the low level anti-aircraft role, and when lowered, it could be placed to allow the gun to be fired "remotely" while it swept an arc in front of the mounting with fire. Mounted to
22701-464: Was a sturdy and simple gun that was easy and cheap to manufacture, and could be relied upon to perform even in the most adverse conditions; it was capable of withstanding being buried in dirt, mud, or sand and still operating consistently. However, being magazine fed, it had a rate of fire similar to other light machine guns, like the Bren light machine gun , but low when compared to its main wartime rivals,
22862-541: Was accepted for Red Army service in 1927 with the official designation 7,62-мм ручной пулемет обр. 1927 г (7.62mm Hand-Held Machine Gun Model 1927). It was called the ДП-27 (DP-27), although some western sources refer to it as the DP-28. Despite its numerous problems, the DP had a reputation as a relatively effective light support weapon. It was nicknamed the "Record player" (proigryvatel') by Red Army troops because of its rotating disc-shaped pan magazine. The first uses of
23023-406: Was also issued to machine guns installed in fixed emplacements such as bunkers. Patronenkasten 34 and Patronenkasten 41 ammunition boxes could hold up to 300 belted rounds and were used in more static non-highly mobile situations. The Patronenkasten could contain an Einführstück belt starter-segment. The Gurttrommel assault drum was an alternative feed option and designed to be clipped to
23184-501: Was conquered by the Soviet Union from the east and the other Allies from the west, and capitulated on 8 May 1945. Hitler's refusal to admit defeat led to massive destruction of German infrastructure and additional war-related deaths in the closing months of the war. The Allies initiated a policy of denazification and put many of the surviving Nazi leadership on trial for war crimes at the Nuremberg trials . Common English terms for
23345-564: Was derived from the Laufschützer 34 that served the same purpose for MG 34 barrel units. Later in the war the universal Laufschützer 43 was introduced that could be used with MG 34 and MG 42 barrel units. For the medium machine gun role a large tripod, the Lafette 42 , was available that included a number of features, such as recoil absorbing buffer springs, a Zielfernrohrhalter (optical sight mounting bracket) for mounting an MG Z 34 or MG Z 40 periscope-type 4× power telescopic sight containing special sighting equipment for indirect fire , or
23506-482: Was developed with the goal of providing a high cyclic rate of fire weapon for anti-aircraft use which was reported to have reached cyclic rates of fire as high as 1,600 rounds per minute. This eventually led to the Einheitsmaschinengewehr (Universal machine gun) introducing an entirely new concept in automatic firepower. By changing its mount, sights and feed mechanism, the operator could radically transform an Einheitsmaschinengewehr for several purposes. The MG 34
23667-417: Was dropped. Germany was now a totalitarian state with Hitler at its head. As head of state, Hitler became Supreme Commander of the armed forces. The new law provided an altered loyalty oath for servicemen so that they affirmed loyalty to Hitler personally rather than the office of supreme commander or the state. On 19 August, the merger of the presidency with the chancellorship was approved by 90 per cent of
23828-447: Was given the task of being involved with the project, although he specialized in the technology of mass production. Gruner would attend an army machine gunner's course to familiarize himself with the utility and characteristics of such a weapon, also seeking input from soldiers. He then recycled an existing Mauser -developed operating system and incorporated features from his experiences with army machine gunners and lessons learned during
23989-641: Was good, and food supplies remained adequate in Western Europe. Germany and Europe as a whole were almost totally dependent on foreign oil imports. In an attempt to resolve the shortage, in June 1942 Germany launched Fall Blau ("Case Blue"), an offensive against the Caucasian oilfields. The Red Army launched a counter-offensive on 19 November and encircled the Axis forces, who were trapped in Stalingrad on 23 November. Göring assured Hitler that
24150-526: Was greeted with cheers when he landed in London, saying the agreement brought "peace for our time". Austrian and Czech foreign exchange reserves were seized by the Nazis, as were stockpiles of raw materials such as metals and completed goods such as weaponry and aircraft, which were shipped to Germany. The Reichswerke Hermann Göring industrial conglomerate took control of steel and coal production facilities in both countries. In January 1934, Germany signed
24311-497: Was in violation of the Versailles Treaty. On 17 May 1933, Hitler gave a speech before the Reichstag outlining his desire for world peace and accepted an offer from American President Franklin D. Roosevelt for military disarmament, provided the other nations of Europe did the same. When the other European powers failed to accept this offer, Hitler pulled Germany out of the World Disarmament Conference and
24472-418: Was its high cyclic rate of fire of about 1,200 to 1,500 rounds per minute, twice the rate of the Vickers and Browning machine guns, which fired at a rate of about 600 rounds per minute. The ear could not easily discern the sound of individual shots being fired, hearing a sound described as like "ripping cloth" or a buzzsaw. The MG 42's high cyclic rate of fire sometimes proved a liability mainly in that, while
24633-635: Was less likely to jam the MG 42 than the more temperamental MG 34. The MG 42 is capable only of fully automatic fire. Single shots are difficult, even for experienced operators, due to the weapon's high cyclic rate of fire and the ability to fire a short burst of no more than three rounds was usually accepted as the training standard. The weapon features a recoil booster at the muzzle which adds extra rearwards force to augment that caused by recoil , thereby improving functional reliability and rate of fire. Besides amplifying recoil and managing and timing rearwards force exerted by propellant gas generated pressure,
24794-510: Was much simpler to build than other machine guns – it took 75 man hours to complete the new gun as opposed to 150 man hours for the MG 34 (a 50% reduction), 27.5 kg (61 lb) of raw materials as opposed to 49 kg (108 lb) for the MG 34 (a 44% reduction) – and cost 250 RM as opposed to 327 RM (a 24% reduction). The initial trials of the Großfuß functional model presented in April 1938 gave rise to improvement requests by
24955-432: Was not prepared to fight should be court-martialed, and thousands of people were executed. In many areas, people surrendered to the approaching Allies in spite of exhortations of local leaders to continue to fight. Hitler ordered the destruction of transport, bridges, industries, and other infrastructure—a scorched earth decree—but Armaments Minister Albert Speer prevented this order from being fully carried out. During
25116-423: Was possible to unintentionally have high pressure gas moving backwards in the MG 42 towards the operator(s) when the action was not fully locked. This causes unacceptable dangerous conditions and out of battery ignitions can result in catastrophic gun failures. Enough guns were damaged and put out of action for repair or lost to warrant finding the cause and a solution. After investigation using high-speed photography
25277-597: Was produced in various wood and bakelite versions. Nazi Germany Nazi Germany , officially known as the German Reich and later the Greater German Reich , was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship . The Third Reich , meaning "Third Realm" or "Third Empire", referred to
25438-443: Was six men: the squad leader, the machine gunner who carried and fired the gun, the assistant gunner/loader who carried the tripod, and three riflemen who carried 1,800 rounds of ammunition between them, spare barrels, entrenching tools, and other items. To enable the machine gun for its long-range direct fire and indirect fire support roles, optical sights could be added to a Zielfernrohrhalter (optical sight mounting bracket) on
25599-540: Was succeeded by Grand Admiral Karl Dönitz as Reich President and Goebbels as Reich Chancellor. Goebbels and his wife Magda committed suicide the next day after murdering their six children . Between 4 and 8 May 1945, most of the remaining German armed forces unconditionally surrendered. The German Instrument of Surrender was signed 8 May, marking the end of the Nazi regime and the end of World War II in Europe . Popular support for Hitler almost completely disappeared as
25760-682: Was the fourth nation to join the Axis, signing the Tripartite Pact on 27 September 1940. Bulgaria signed the pact on 17 November. German efforts to secure oil included negotiating a supply from their new ally, Romania , who signed the Pact on 23 November, alongside the Slovak Republic. By late 1942, there were 24 divisions from Romania on the Eastern Front, 10 from Italy, and 10 from Hungary. Germany assumed full control in France in 1942, Italy in 1943, and Hungary in 1944. Although Japan
25921-483: Was weak and likely to fail if not handled with care. Replacing the barrel was not a quick operation due to a lack of handle and the amount of disassembly needed, though a well trained crew could do so in 30 seconds under ideal conditions. The open gas chamber and bolt frame could accumulate dust in sandy conditions, clogging the gas piston. The recoil spring's location near the barrel led to overheating, causing it to lose proper spring temper . The Degtyaryov machine gun
