Solothurn S-18/1000
The Solothurn S18-1000 20 mm was a German anti-tank rifle designed and manufactured in Switzerland and used during the Second World War. It was a variant of the earlier Solothurn S-18/100, S-18/100 with modifications for a higher muzzle velocity, as well as a larger cartridge (firearms), cartridge size. The more powerful ammunition resulted in significant recoil, which was problematic for the gunner, and its size made portability difficult. History The Waffenfabrik Solothurn firearms company was owned by the German firm Rheinmetall, who used the Swiss company to manufacture arms which were prohibited for manufacture by any German firm under arms limitations imposed at the end of the First World War. In 1940–1941 the US Army considered adopting the Solothurn S18-1000. The weapon was standardized for limited procurement as ''20mm automatic gun T3''. In spring 1941 the Solothurn was tested against the Colt .90-cal. (23mm) T4 automatic gun, an aircraft gun. Although not as ...

20 ITK 40 VKT
The 20 ItK 40 VKT or ''20 mm dual anti-aircraft cannon model 1940 manufactured by VKT'' was a Finnish light anti-aircraft gun designed by the Finnish gunsmith Aimo Lahti. As the only multi-barrel 20 mm anti-aircraft gun, the 20 ItK 40 VKT was the most effective 20 mm air defence weapon used by the Finnish Army during World War II. A total of 174 guns were built, used in training until the 1970s and kept in reserve until 1988. The gun received the nickname ''Vekotin'' (gadget) from Finnish soldiers. The nickname was reached by adding to the abbreviation of manufacturer, VKT. Background The 20 ItK 40 VKT is a dual anti-aircraft gun designed by Aimo Lahti. The gun barrels and mechanisms are based on the L-39 anti-tank rifle converted from semi-automatic to full automatic fire and with the stock and barrel shroud removed. A prototype L-39 anti-aircraft gun was completed just before the Winter War, but Lahti made some improvements to the design and the mass-production versi ...

2 Cm Flak 30/38/Flakvierling
The Flak 30 (''Flugzeugabwehrkanone 30'') and improved Flak 38 were 20 mm anti-aircraft guns used by various German forces throughout World War II. It was not only the primary German light anti-aircraft gun but by far the most numerously produced German artillery piece throughout the war. It was produced in a variety of models, notably the Flakvierling 38 which combined four Flak 38 autocannons onto a single carriage. Development 2 cm C/30, 2 cm Flak 30 The Germans fielded the unrelated early 2 cm Flak 28 just after World War I, but the Treaty of Versailles outlawed these weapons and they were sold to Switzerland. The original Flak 30 design was developed from the Solothurn ST-5 as a project for the Kriegsmarine, which produced the 2 cm C/30. The gun fired the "Long Solothurn", a 20 × 138 mm belted cartridge that had been developed for the ST-5 and was one of the more powerful 20 mm rounds. The C/30, featuring a barrel length of 65 ca ...

Solothurn S-18/1100
The Solothurn S-18/1100 was a German 20 mm anti-tank rifle used during the Second World War by a number of combatants. History As a result of the defeat of the central-powers during World War I and the subsequent Treaty of Versailles, Germany was forbidden from developing arms. In order to circumvent these limitations many German arms firms opened foreign subsidiaries or bought controlling interests to continue designing and selling arms. One of these companies was the Swiss Waffenfabrik Solothurn company which was owned by the German firm Rheinmetall. Design The S-18/1100 started life as a selective fire variant of the earlier S-18/1000 anti-tank rifle. As a result of its powerful ammunition, the gun had tremendous recoil. Also, its length and weight made portability difficult, so a two-wheeled split-trail carriage was provided. Once towed into position the gun could be fired from the carriage or dismounted and fired from a bipod for the anti-tank role. In the ...

Lahti L-39
The Lahti L-39 is a Finnish 20 mm anti-tank rifle used during the Second World War. It had excellent accuracy, penetration and range, but its size made transportation difficult. It was nicknamed "Norsupyssy" ("Elephant Gun"), and as tanks developed armor too thick for the Lahti to penetrate, its uses switched to long range sniping, tank harassment and with the L-39/44 fully automatic variant, employment as an improvised anti-aircraft weapon. Development Aimo Lahti had doubts about the original idea of a 13 mm anti-tank machine gun and started working on a 20 mm design. Officers who wanted smaller caliber anti-tank weapons believed that the muzzle velocities of 20 mm shells were insufficient to penetrate armor, and a weapon with a higher rate of fire and in a smaller caliber would prove useful. As a result, Lahti designed two competing anti-tank weapons: a 13.2 mm machine gun and a 20 mm rifle. After test firing both weapons in 1939, they found that ...

Cannone-Mitragliera Da 20/65 Modello 35 (Breda)
The Breda 20/65 mod.35 (''"Breda 20 mm L/65 model 1935"''), also simply known as 20 mm Breda or Breda Model 35, among other variations, was an Italian anti-aircraft gun produced by the Società Italiana Ernesto Breda of Brescia company during the 1930s and early 1940s. It saw heavy usage during the Spanish Civil War and World War II, among other conflicts. It was designed in 1932 and adopted by the Italian armed forces in 1935, becoming one of two major 20 mm caliber anti-aircraft guns used by Italy during World War II, along with the Scotti-Isotta Fraschini 20/70 (Scotti 20 mm), both of which fired the Swiss 20x138mmB "Solothurn Long" cartridge. The Royal Italian Army designated the gun Cannone-Mitragliera da 20/65 ( "Cannon-Machinegun 20/65"), and the mount modello 35 (model 1935), or mod.35 for short. Later, a mod.39 (1939) and a mod.40 (1940) system were introduced, featuring the same gun but in new mounts. The ''"20/65"'' part of the name refers to the calib ...

20 Mm Caliber
20 mm caliber is a specific size of popular autocannon ammunition. The dividing line between smaller-caliber weapons, commonly called "guns", from larger-caliber "cannons" (e.g. machine gun vs. autocannon), is conventionally taken to be the 20 mm round, the smallest caliber of autocannon. All 20 mm cartridges have an outside projectile (bullet) diameter and barrel bore diameter of approximately . These projectiles are typically long, cartridge cases are typically long, and most are shells, with an explosive payload and detonating fuze. Weapons using this caliber range from anti-materiel rifles and anti-tank rifles to aircraft autocannons and anti-aircraft guns. Usage Twenty millimeter caliber weapons are generally not used to target individual soldiers, but rather objects such as vehicles, buildings, or aircraft. Types of ammunition *High explosive (HE) *High explosive incendiary (HEI) *Armor-piercing (AP) * Semi-armor-piercing high explosive incendiary (SAPHEI) *Ar ...

2 Cm KwK 30
The 2 cm KwK 30 L/55 ''(2 cm Kampfwagenkanone 30 L/55)'' was a German 2 cm cannon used as the main armament of the German Sd.Kfz.121 Panzerkampfwagen II light tank and various reconnaissance vehicles. It was used during the Spanish Civil War and the Second World War. It was produced by Mauser and Rheinmetall-Borsig from 1935. The KwK 30 also served as the basis for the 20 mm C/30, an aircraft variant mounted experimentally in some Heinkel He 112 fighters and proved to make an excellent ground-attack weapon during the Spanish Civil War. Direct ground-attack was not considered a priority for the Luftwaffe The Luftwaffe () was the aerial warfare, aerial-warfare branch of the before and during World War II.

Solothurn ST-5
The Solothurn ST-5 is a 20 mm anti-aircraft gun designed by Waffenfabrik Solothurn in Switzerland which ultimately was the design basis for the highly successful 2 cm Flak 30 series of guns used by Germany in World War II. Solothurn was owned by the German firm Rheinmetall, which at the time was prohibited from developing certain weapons. It and other German manufacturers sought partnerships with foreign firms, often owning them outright, in an effort to circumvent the terms of the Versailles Treaty. The gun was initially developed by Germans engineers employed in a Dutch front company of Rheinmetall, ''Hollandsche Industrie- en Handelsmaatschappij'' (H.I.H., informally also "Haiha") which is better known as HIH Siderius. The ST-5 fired the 'Long Solothurn' ammunition, the cartridge 20 × 138 mm. B. The cartridge case was 138 mm long, making it the most powerful 20 mm round available.
