Emil (tank)
Emil, also known as the Kranvagn, KRV or Emil Olsson was a heavy tank developed secretly in Sweden during the early 1950s; ''Kranvagn'', meaning mobile crane was a cover-name. The intention was to replace the Swedish Army's disparate tank fleet with a tank that could counter the Soviet IS series heavy tanks and be upgraded continuously. The initial design, in 1950, proposed mounting a 10.5 cm autoloader in an oscillating turret. Due to its size, weight and power to weight it was considered by many to be more of a medium tank than a heavy tank. The project was discontinued during development and only two chassis were built. They were later rebuilt and served as testing platforms for the '' Artillerikanonvagn 151'' and '' Stridsvagn 103'' projects. Project At the end of World War II, it was clear that the mix of tanks in service in the Swedish Armed Forces was not just obsolete but also presented a large logistical problem.

AMX-13
The AMX-13 is a French light tank produced from 1952 to 1987. It served with the French Army, as the Char 13t-75 Modèle 51, and was exported to more than 26 other nations. Named after its initial weight of 13 tonnes, and featuring a tough and reliable chassis,''The Complete Guide to Tanks and Armoured Fighting Vehicles'', it was fitted with an oscillating turret built by GIAT Industries (now Nexter) with revolver type magazines, which were also used on the Austrian SK-105 Kürassier. Including prototypes and export versions, over a hundred variants exist, including self-propelled guns, anti-aircraft systems, APCs, and ATGM versions. Development The tank was designed at the Atelier de Construction d'Issy-les-Moulineaux (AMX) in 1946 to meet a requirement for an air-portable vehicle to support paratroopers. The first prototype ran from 1948. The compact chassis had torsion bar suspension with five road-wheels and two return rollers; the engine runs the length of the tank on ...

Tanks Of Sweden
This article deals with the history and development of tanks employed by the military of Sweden, from the interwar period, and World War II, the Cold War and modern era. History Following World War I, the Swedish government purchased parts for the German tank prototype LK II and then assembled in Sweden as the ''Stridsvagn m/21'' (Strv m/21 for short), which was essentially an improved version of the LK II prototype. Ten of these tanks were built, their armament a single machine gun. In 1929, five were rebuilt to create the Strv m/21-29 variant which was armed with a 37mm gun or two machine guns and was powered by a Scania-Vabis engine. The Stridsvagn m/31 (Landsverk L-10) tank was the next design and built by AB Landsverk. It was armed with a 37 mm Bofors gun and a light machine gun, and was equipped with 8–24 mm armor. Only three were built and, despite being highly advanced for the time when World War II broke out, they were dug in as static bunkers. Sweden orde ...

Rifled Gun
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrels ...

Smoothbore
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, improvin ...

Panther Tank
The Panther tank, officially ''Panzerkampfwagen V Panther'' (abbreviated PzKpfw V) with ordnance inventory designation: ''Sd.Kfz.'' 171, is a German medium tank of World War II. It was used on the Eastern and Western Fronts from mid-1943 to the end of the war in May 1945. On 27 February 1944 it was redesignated to just ''PzKpfw Panther'', as Hitler ordered that the Roman numeral "V" be deleted. In contemporary English-language reports it is sometimes referred to as the "Mark V". The Panther was intended to counter the Soviet T-34 medium tank and to replace the Panzer III and Panzer IV. Nevertheless, it served alongside the Panzer IV and the heavier Tiger I until the end of the war. It had excellent firepower, protection and mobility, although its reliability was less impressive. The Panther was a compromise. While having essentially the same Maybach V12 petrol (690 hp) engine as the Tiger I, it had better gun penetration, was lighter and faster, and could traverse roug ...

White Paper
A white paper is a report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision. A white paper is the first document researchers should read to better understand a core concept or idea. The term originated in the 1920s to mean a type of position paper or industry report published by some department of the UK government. Since the 1990s, this type of document has proliferated in business. Today, a business-to-business (B2B) white paper is closer to a marketing presentation, a form of content meant to persuade customers and partners and promote a certain product or viewpoint. That makes B2B white papers a type of grey literature. In government The term ''white paper'' originated with the British government and many point to the Churchill White Paper of 1922 as the earliest well-known example under this name.

Bofors
AB Bofors ( , , ) is a former Swedish arms manufacturer which today is part of the British arms concern BAE Systems. The name has been associated with the iron industry and artillery manufacturing for more than 350 years. History Located in Karlskoga, Sweden, the company originates from the hammer mill "Boofors", which was founded as a royal state-owned company in 1646. The modern corporate structure was created in 1873 with the foundation of Aktiebolaget (AB) Bofors-Gullspång. The Bofors Works was acquired by Johan Eberhard Geijer in 1762. It was then acquired by the latter's brother, Emanuel af Geijerstam. A leading Swedish steel producer by the early 1870s, when steel began to be used for gun manufacture in Sweden, Bofors initially sold cast and forged steel produced by the Siemens-Martin process to Finspång gun works, but soon started to expand into weapons manufacture. The company's first cannon workshop was opened in 1884. Bofors' most famous owner was Alfred Nob ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

AB Landsverk
Landsverk (AB Landsverk) was a Swedish heavy industry company, manufacturing military equipment such as tanks, tank destroyers, SPAAGs, armored cars, tracked and wheeled off-road vehicles among others and civilian equipment such as railroad cars, harbour cranes and agricultural machinery. It was founded in 1872 as ''Firman Petterson & Ohlsen''. It was located in Landskrona, Sweden. Early days In late 1920 the company found itself on the verge of bankruptcy. Through a German company, the German ''Gutehoffnungshütte Aktienverein für Bergbau und Hüttenbereich Oberhausen'' (GHH), invested heavily and gained control of 50% of the shares. In 1923 the company manufactured a small number of tracked agricultural tractors based on an American design. The Germans increased their ownership to 61% in 1925, three years later the name was changed to ''AB Landsverk''. In 1929 the German engineer Otto Merker was assigned to Landsverk to develop armoured vehicles, a few prototypes of a Germa ...
