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 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 20 mm 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 calibres, had a fire rate of ab ...

Anti-aircraft Gun
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircra ...

Mine Shell
A mine shell (from the German term ''Minengeschoß'', "mine shot"), also known as High-Explosive, High-Capacity (HEHC) in British military nomenclature, is a military explosive shell type characterized by thin (usually steel) shell walls and a correspondingly high quantity of explosives, much higher than the traditional high explosive shell type per caliber, meaning that mine shells trade fragmentation effect (due to the thinner shell walls) for a higher pressure wave effect when comparing to traditional high explosive shells. Mine shells were originally developed during the mid to late 1800s against fortresses prior to rebar but got a new role during World War II against air targets as reinforced fortresses had made the original use of the type obsolete around World War I. Effect, construction and use The mine shell is a more explosive version of the common high-explosive and high-explosive fragmentation shells, relying on inflicting damage primarily through the blast (press ...

Mauser
Mauser, originally Königlich Württembergische Gewehrfabrik ("Royal Württemberg Rifle Factory"), was a German arms manufacturer. Their line of bolt-action rifles and semi-automatic pistols has been produced since the 1870s for the German armed forces. In the late 19th and early 20th centuries, Mauser designs were also exported and licensed to many countries which adopted them as military and civilian sporting firearms. The Gewehr 98 in particular was widely adopted and copied, and is the foundation of many of today's sporting bolt-action rifles. History King Frederick I founded the enterprise as Königliche Waffen Schmieden (literally: Royal Weapons Forges) on 31 July 1811. Originally located partly at Ludwigsburg and partly in Christophsthal, the factory transferred to the former Augustine Cloister in Oberndorf am Neckar, where Andreas Mauser worked as the master gunsmith. Of his seven sons who worked with him there, Peter Paul Mauser showed an outstanding ability to ...

Solothurn ST-5
The Solothurn ST-5 is a 20 mm anti-aircraft gun designed by 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 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. Users * - While Germany did not adopt the ST-5, the Kriegsmarine did acquire a version of the weapon for ship-board air defense. The weapon was designated 20 mm C/30 and equipped several German naval vessels during World War II. This weapon was further refined for the other German forces as the 2 cm Flak 30 ...

Saumur
Saumur () is a commune in the Maine-et-Loire department in western France. The town is located between the Loire and Thouet rivers, and is surrounded by the vineyards of Saumur itself, Chinon, Bourgueil, Coteaux du Layon, etc.. Saumur station has rail connections to Tours, Angers, La Roche-sur-Yon and Nantes. Toponymy First attested in the Medieval Latin form of ''Salmuri'' in 968 AD, the origin of the name is obscure. Albert Dauzat hypothesized a pre-Celtic unattested element ''*sala'' 'marshy ground' (''cf.'' Celtic ''salm'' 'which jumps and flows'), followed by another unattested element meaning "wall". Many places in Europe seem to contain ''*Sal(m)-'' elements, which may share Old European roots. History The Dolmen de Bagneux on the south of the town, is 23 meters long and is built from 15 large slabs of the local stone, weighing over 500 tons. It is the largest in France. The Château de Saumur was constructed in the 10th century to protect the Loire River cr ...

Tungsten Carbide
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, cutting tools, chisels, abrasives, armor-piercing shells and jewelry. Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa, and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-) in hardness and can be polished and finished only with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels and compounds. Naming Historically referred to as Wolfram, ''Wolf Rahm'', wolframite ore was then later carburized and cemented with a binder creating a composite now called "tungsten carbide". Tungsten is Swedish for "heavy stone". Co ...

Pentaerythritol Tetranitrate
Pentaerythritol tetranitrate (PETN), also known as PENT, PENTA, (ПЕНТА, primarily in Russian) TEN, corpent, or penthrite (or, rarely and primarily in German, as nitropenta), is an explosive material. It is the nitrate ester of pentaerythritol, and is structurally very similar to nitroglycerin. Penta refers to the five carbon atoms of the neopentane skeleton. PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive. Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. History Pentaerythritol tetranitrate was first prepared and patented in 1894 by the explosives manufacturer Rheinisch-Westfälische Sprengstoff A.G. of Cologne, Germany. The production of PETN started in 1912, when the improved method of production was patented by the German government. PETN was used by the ...
