World War II saw rapid technological innovation in response to the needs of the various combatants. Many different weapons systems evolved as a result.
This list does not consist of all weapons used by all countries in World War II.
The MP 40 is a submachine gun chambered for the 9×19mm Parabellum cartridge. It was developed in Nazi Germany and used extensively by the Axis powers during World War II.
The StG 44 is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44. The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H).
The Lewis gun is a First World War–era light machine gun. Designed privately in the United States though not adopted there, the design was finalised and mass-produced in the United Kingdom, and widely used by troops of the British Empire during the war. It had a distinctive barrel cooling shroud, and top-mounted pan magazine. The Lewis served until the end of the Korean War, and was widely used as an aircraft machine gun during both World Wars, almost always with the cooling shroud removed, as air flow during flight offered sufficient cooling.
The M2 machine gun or Browning .50 caliber machine gun is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's M1919 Browning machine gun, which was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG cartridge. The design has had many designations; the official U.S. military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It has been used against infantry, light armored vehicles, watercraft, light fortifications, and low-flying aircraft.
The M4 carbine is a 5.56×45mm NATO assault rifle developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle.
A semi-automatic firearm, also called a self-loading or autoloading firearm, is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, and allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
Carcano is the frequently used name for a series of Italian bolt-action, internal box magazine fed, repeating military rifles and carbines. Introduced in 1891, the rifle was chambered for the rimless 6.5×52mm Carcano round. It was developed by the chief technician Salvatore Carcano at the Turin Army Arsenal in 1890, and was originally called the Modello (model) 91 or simply M91. Successively replacing the previous Vetterli-Vitali rifles and carbines in 10.35×47mmR, it was produced from 1891 to 1945. The M91 was used in both rifle (fucile) and shorter-barreled carbine (moschetto) form by most Italian troops during World War I and by Italian and some German forces during World War II. The rifle was also used during the Winter War by Finland, and again by regular and irregular forces in Syria, Libya, Tunisia, and Algeria during various postwar conflicts in those countries.
Lists of World War II military equipment are lists of military equipment in use during World War II (1939–1945). They include lists of aircraft, ships, vehicles, weapons, personal equipment, uniforms, and other equipment. There are aggregated military equipment lists by country, and lists of classes of equipment broken down by country or by type.
The .380 ACP, also known as .380 Auto, .380 Automatic, or 9×17mm, is a rimless, straight-walled pistol cartridge that was developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case. It was introduced in 1908 by Colt, for use in its new Colt Model 1903 Pocket Hammerless semi-automatic, and has been a popular self-defense cartridge ever since, seeing wide use in numerous handguns. Other names for .380 ACP include 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9mm Browning Court. It should not be confused with .38 ACP. The .380 ACP does not strictly conform to cartridge naming conventions, named after the diameter of the bullet, as the actual bullet diameter of the .380 ACP is .355 inches.
The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire. It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. The "Mini" in the name is in comparison to larger-caliber designs that use a rotary barrel design, such as General Electric's earlier 20 mm M61 Vulcan, and "gun" for the use of rifle ammunition as opposed to autocannon shells.
The Walther P38 is a 9 mm semi-automatic pistol that was developed by Carl Walther GmbH as the service pistol of the Wehrmacht at the beginning of World War II. It was intended to replace the comparatively complex and expensive to produce Luger P08. Moving the production lines to the more easily mass producible P38 once World War II started took longer than expected, leading to the P08 remaining in production until September 1942 and copies remained in service until the end of the war.
The PPSh-41 is a selective-fire, open-bolt, blowback submachine gun that fires the 7.62×25mm Tokarev round. It was designed by Georgy Shpagin of the Soviet Union to be a cheaper and simplified alternative to the PPD-40.
A service rifle is a rifle a military issues to its regular infantry. In modern militaries, this is generally a versatile, rugged, and reliable assault rifle or battle rifle, suitable for use in nearly all environments and is effective in most combat situations. Almost all modern militaries are issued service pistols as sidearms to accompany their service rifles. The term can also be used to describe weapons issued by non-military forces, such as law enforcement or paramilitaries.

The German submachine gun EMP also known as MPE was produced by the Erma factory, and was based on designs acquired from Heinrich Vollmer. The gun was produced from 1931 to 1938 in roughly 10,000 copies and exported to Spain, Mexico, China and Yugoslavia, but also used domestically by the SS. It was produced under license in Spain by the arsenal of A Coruña under the designation M41/44.
During World War II, Germany maintained comprehensive lists of enemy weapons which were given designations in German in a system that matched that of German weapons. When these weapons were captured and put into use with German forces they were referred to by these designations.
