MKb 42(W)
The Maschinenkarabiner 42(W) (German: "machine carbine model 1942 (Walther)" ) or MKb 42(w) was an early German assault rifle designed in 1940-41 by Walther during World War II. The Mkb 42(W), and the more successful Maschinenkarabiner 42(H) designed by Haenel, were predecessors of the Sturmgewehr 44 (StG 44) assault rifle. History As early as 1918 the German Army began to study the feasibility of an intermediate round and rifle. However, a combination of military orthodoxy, limited funds and the arms development restrictions of the Versailles Treaty led Germany to adopt the Mauser Karabiner 98K on 21 June 1935. From 1939 onwards the German Army gathered combat reports which were analyzed to determine combat conditions and tactical trends in order to develop new tactics and equipment requirements. One of the lessons which re-emerged was the existing 7.92x57mm rifle cartridge was more powerful and long ranged than what was needed. Since most combat took place at ranges less ...

Closed Bolt
A semi or full-automatic firearm which is said to fire from a closed bolt is one where, when ready to fire, a round is in the chamber and the bolt and working parts are forward. When the trigger is pulled, the firing pin or striker fires the round; the action is cycled by the energy of the shot, sending the bolt to the rear, which extracts and ejects the empty cartridge case; and the bolt goes forward, feeding a fresh round from the magazine into the chamber, ready for the next shot. World War I aircraft When World War I era machine guns were being tried for use on aircraft, the Lewis gun was found not to be usable with a gun synchronizer for forward firing through the propeller, due to its firing cycle starting with an open bolt. Maxim style arms fired with a cycle starting with a closed bolt, and since the bullet firing from the gun started the firing cycle, it was much easier to set the synchronizer to trigger the gun only when the propeller's blade was not directly in ...

Weapons And Ammunition Introduced In 1943
A weapon, arm or armament is any implement or device that can be used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target. While ordinary objects – sticks, rocks, bottles, chairs, vehicles – can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs, axes and swords, to complicated modern firearms, tanks, intercontinental ballistic missiles, biological weapons, and cyberweapons. Something that has been re-purposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser. History The use of weapons is a major driver of cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Assault Rifles
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In '' scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research And Development In Nazi Germany
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-operated Firearms
Gas-operation is a system of operation used to provide energy to operate locked breech, Semi-automatic firearm, autoloading firearms. In gas-operation, a portion of high-pressure gas from the Cartridge (firearms), cartridge being fired is used to power a mechanism to dispose of the spent Casing (ammunition), case and insert a new cartridge into the Chamber (firearms), chamber. Energy from the gas is harnessed through either a port in the Gun barrel, barrel or a trap at the Muzzle (firearms), muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the Firearm action, action, extraction of the spent case, ejection, cocking of the Hammer (firearm), hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Assault Rifles
An assault rifle is a rifle that uses an intermediate cartridge, a detachable magazine, and can switch between semi-automatic/fully automatic fire. Assault rifles are currently the standard service rifles in most modern armies. Some rifles listed below such as the AR15 also come in semi-auto models which would not belong under the term "Assault Rifle". Definition By strict definition, a firearm must have the following characteristics to be considered an assault rifle: * It must be an individual weapon; * It must be capable of selective fire, which means it has the capacity to switch between semi-automatic and burst/fully automatic fire; * It must have an intermediate-power cartridge: more power than a pistol but less than a standard rifle or battle rifle. For full-power automatic rifles, see List of battle rifles; * Its ammunition must be supplied from a detachable box magazine; * It should have an effective range of at least . Rifles that meet most of these criteria, but not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AK-47
The AK-47, officially known as the ''Avtomat Kalashnikova'' (; also known as the Kalashnikov or just AK), is a gas operated, gas-operated assault rifle that is chambered for the 7.62×39mm cartridge. Developed in the Soviet Union by Russian small-arms designer Mikhail Kalashnikov, it is the originating firearm of the Kalashnikov rifle, Kalashnikov (or "AK") family of rifles. After more than seven decades since its creation, the AK-47 model and its variants remain one of the most popular and widely used firearms in the world. The number "47" refers to the year the rifle was finished. Design work on the AK-47 began in 1945. It was presented for official military trials in 1947, and, in 1948, the fixed-Stock (gun), stock version was introduced into active service for selected units of the Soviet Army. In early 1949, the AK was officially accepted by the Soviet Armed Forces and used by the majority of the member states of the Warsaw Pact. The model and its variants owe their glob ...

Fedorov Avtomat
The Fedorov Avtomat (also anglicized as Federov, ) or FA is a select-fire infantry rifle and also one of the world's first operational automatic rifles, designed by Vladimir Grigoryevich Fyodorov in 1915 and produced in the Russian Empire and later in the Russian Soviet Federative Socialist Republic. A total of 3,200 Fedorov rifles were manufactured between 1915 and 1924 in the city of Kovrov; the vast majority of them were made after 1920. The weapon saw limited combat in World War I, but was used more substantially in the Russian Civil War and in the Winter War. Some consider it to be an "early predecessor" or "ancestor" of the modern assault rifle. Design and development The Fedorov Avtomat is a short-recoil operated, locked-breech weapon which fires from a closed bolt. The bolt locking is achieved by a pair of symmetrical plates mounted to either side of the breech and held in place by a sheet metal cover, each with two lugs, one square and one round, mounted at either sid ...

AS-44
The Sudayev AS-44 (Avtomat Sudayeva, ''Автома́т Суда́ева'') was an early Soviet automatic rifle that was designed in 1944 by Alexey Sudayev. It was produced in limited numbers and tested during 1945, but its development ended in 1946 due to the death of its designer. History In 1943 the highly successful 7.62×39mm Soviet intermediate cartridge was developed and provided to Soviet small arms design bureaus to use in a new series of automatic rifles. A design competition was announced and at least ten different designs were submitted for testing from designers such as Fedorov, Tokarev, Simonov, and Shpagin. In May 1944 Alexey Sudayev who had already designed the successful PPS submachine gun delivered the first and fourth models of his AS-44 for tests. The AS-44 successfully met the competition's requirements and in the spring of 1945, an experimental batch of AS-44 assault rifles was manufactured at the Tula Arms Factory. During the summer of 1945, these wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Front (World War II)
The Eastern Front of World War II was a Theater (warfare), theatre of conflict between the European Axis powers against the Soviet Union (USSR), Polish Armed Forces in the East, Poland and other Allies of World War II, Allies, which encompassed Central Europe, Eastern Europe, Northern Europe, Northeast Europe (Baltic states, Baltics), and Southeast Europe (Balkans) from 22 June 1941 to 9 May 1945. It was known as the Great Patriotic War (term), Great Patriotic War in the Soviet Union – and still is in some of its successor states, while almost everywhere else it has been called the ''Eastern Front''. In present-day German and Ukrainian historiography the name German-Soviet War is typically used. The battles on the Eastern Front of the Second World War constituted the largest military confrontation in history. They were characterised by unprecedented ferocity and brutality, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, expos ...

Kummersdorf
Kummersdorf is the name of an estate near Luckenwalde, around 25 km south of Berlin, in the Brandenburg region of Germany. Until 1945 Kummersdorf hosted the weapon office of the German Army which ran a development centre for future weapons as well as an artillery range. Early history In 1871, the Prussian ministry of war decided to move the artillery test range at Tegel to the Kummersdorf Forest. The new range became operational on 15 October 1875 when it was connected with the Royal Prussian Military Railway. In 1880, the first firing experiments took place on the 12 km southeast-northwest firing range. These experiments investigated the effectiveness of various fortifications, and the effects of weapons and projectiles. Total size of the Kummersdorf Firing Range was 878.1 hectares. In 1913, the dropping of bombs from the LZ 13 Hansa airship and Wright biplanes was investigated. In the 1920s, secret development started in the areas of artillery, armored forces, mo ...
