20 Mm Polsten
The Polsten was a Polish development of the 20 mm Oerlikon gun. The Polsten was designed to be simpler and much cheaper to build than the Oerlikon, without reducing effectiveness. Development When Nazi Germany invaded Poland in 1939, the Polish design team escaped to the U.K. and resumed work together with Czech and British designers. The need for the Polsten was apparently mooted in June 1941. It went into service in March 1944 alongside the Oerlikon. Both the Oerlikon and the Polsten used similar 60 round drum magazines, however, the Polsten could also use a simpler box magazine with 30 rounds. It remained in service into the 1950s. Used like Oerlikon When compared to the Oerlikon cannon which was made out of 250 parts, the Polsten was made out of 119 parts, without sacrificing the effectiveness or the reliability of the cannon. Simplification of the design of the Polsten cannon made its production much cheaper. The cost of one Oerlikon cannon was about £350, while th ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally " rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mo ...

Skink Anti-aircraft Tank
Tank AA, 20 mm Quad, Skink was a Canadian self-propelled anti-aircraft gun, developed in 1943–44, in response to a requirement from the First Canadian Army. Due to a lack of threat from the German , the Skink was cancelled in 1944 after only 3 were built from Grizzly I cruisers. Development The development of a fully enclosed quadruple 20 mm mounting on the chassis of the Grizzly tank (M4A1 Sherman tanks built in Canada from August 1943) was approved by the Canadian Army Technical Development Board as Project 47 in March, 1943. In keeping with the tradition of giving Canadian armoured fighting vehicles animal names, the proposed tank was named after the skink, Ontario's only lizard. The Canadian Ministry of Munitions and Supply had the turret designed in-house by its Army Engineering Design Branch (AEDB) with help from the Inspection Board. The Waterloo Manufacturing Co. in Waterloo, Ontario, was given the task of building a preliminary wooden mock-up. This wa ...

World War II Weapons Of Poland
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] |

History Of The Second World War
The ''History of the Second World War'' is the official history of the British contribution to the Second World War and was published by Her Majesty's Stationery Office (HMSO). The immense project was sub-divided into areas to ease publication, ''United Kingdom Military Series'', the ''United Kingdom Civil Series'' for the civilian war effort; the ''Foreign Policy series'', the ''Intelligence series'' and the ''Medical series'' are eponymous. Other volumes not under the aegis of the series but published by HMSO may be read as adjuncts, covering matters not considered in great detail or at all, in one case, in the main series. Further volumes, published after the privatisation of HMSO or in the series about the Special Operations Executive, are also useful. The volumes were intended to be read individually, rather than in series, which led to some overlapping. In their introductions to their parts of the series, Sir Keith Hancock and Sir James Butler wrote that this was to obv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bren
The Bren gun was a series of light machine guns (LMG) made by Britain in the 1930s and used in various roles until 1992. While best known for its role as the British and Commonwealth forces' primary infantry LMG in World War II, it was also used in the Korean War and saw service throughout the latter half of the 20th century, including the 1982 Falklands War. Although fitted with a bipod, it could also be mounted on a tripod or be vehicle-mounted. The Bren gun was a licensed version of the Czechoslovak ZGB 33 light machine gun which, in turn, was a modified version of the ZB vz. 26, which British Army officials had tested during a firearms service competition in the 1930s. The later Bren gun featured a distinctive top-mounted curved box magazine, conical flash hider, and quick change barrel. The name ''Bren'' was derived from Brno, the Czechoslovak city in Moravia, where the Zb vz. 26 was designed (in the Zbrojovka Brno Factory) and Enfield, site of the British Royal Small Arm ...

Royal Small Arms Factory
The Royal Small Arms Factory (RSAF) was a UK government-owned rifle factory in Enfield (though some parts were in Waltham Abbey), adjoining the Lee Navigation in the Lea Valley. The factory produced British military rifles, muskets and swords from 1816. It closed in 1988, but some of its work was transferred to other sites. The factory designed and manufactured many famous British Army weapons including the Lee–Enfield rifles which were standard equipment during both World Wars. History The RSAF had its origins in a short-lived Royal Manufactory of Small Arms established in Lewisham in 1807. (The site in Lewisham was a mill where armour had been made since the fourteenth century; following its purchase by Henry VIII in 1530, it became known as the Royal Armoury Mills and served his armoury in Greenwich.) During the Napoleonic War, the increasing demand for large quantities of reliable weapons prompted the Board of Ordnance to look into building a new factory on a ...

Sten
The STEN (or Sten gun) is a family of British submachine guns chambered in 9×19mm which were used extensively by British and Commonwealth forces throughout World War II and the Korean War. They had a simple design and very low production cost, making them effective insurgency weapons for resistance groups, and they continue to see usage to this day by irregular military forces. The Sten served as the basis for the Sterling submachine gun, which replaced the Sten in British service until the 1990s, when it, and all other submachine guns, were replaced by the SA80. The Sten is a select fire, blowback-operated weapon which mounts its magazine on the left. Sten is an acronym, from the names of the weapon's chief designers, Major Reginald V. Shepherd and Harold J. Turpin, and "En" for the Enfield factory. Over four million Stens in various versions were made in the 1940s, making it the second most produced submachine gun of the Second World War, after the Soviet PPSh-41. Histo ...

Centurion Tank
The Centurion was the primary British Army main battle tank of the post- World War II period. Introduced in 1945, it is widely considered to be one of the most successful post-war tank designs, remaining in production into the 1960s, and seeing combat into the 1980s. The chassis was adapted for several other roles, and these variants have remained in service. It was a very popular tank with good armour, manoeuvrability, and armament. Development of the Centurion began in 1943 with manufacture beginning in January 1945. Six prototypes arrived in Belgium less than a month after the war in Europe ended in May 1945. It entered combat with the British Army in the Korean War in 1950 in support of the UN forces. The Centurion later served on the Indian side in the Indo-Pakistani War of 1965, where it fought against US-supplied M47 and M48 Patton tanks, and it served with the Royal Australian Armoured Corps in the Vietnam War. Israel's army used Centurions in the 1967 Six-Day ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
