Emil (tank)
Heavy tank project Emil (project number: ''6400''), known under the cover name of Kranvagn ("crane wagon") or KRV for short, 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 l ...

Minister For Defence (Sweden)
The Minister for Defence of Sweden (; formal title: ) is a member of the Government of Sweden (). The Minister heads the Ministry for Defence and is appointed and dismissed at the sole discretion of the prime minister of Sweden. Although the Minister for Defence heads the Ministry of Defence, the Minister cannot as a general rule issue directives in his/her own right to the Supreme Commander or any other agency director-general in the defence portfolio due to the Swedish prohibition on ministerial rule, unless such authority is provided for in specific statutory provisions. Between 1840 and 1920, what corresponds to the Ministry for Defence today, was divided in two separate ministries with their own minister: one for Army affairs, the Ministry of Land Defence, and one for Naval affairs, the Ministry for Naval Affairs. The current Minister for Defence is Pål Jonson, who was appointed on 18 October 2022. List of Swedish Ministers for Defence Ministers for War (1840-1920) ...

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 order ...

Rifled Gun
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56 ...

Armour-piercing Discarding Sabot
Armor-piercing discarding sabot (APDS) is a type of Rifling, spin-stabilized kinetic energy penetrator, kinetic energy projectile for anti-armor warfare. Each projectile consists of a sub-caliber round fitted with a Sabot (firearms), sabot. The combination of a lighter sub-caliber projectile with a full-caliber propellant charge allows for an increase in muzzle velocity compared to full-caliber rounds, giving the round increased armor-penetration performance. To further enhance their armor-penetration capabilities, APDS rounds typically feature a hardened core made from tungsten or another hard, dense material. For a given caliber, APDS ammunition can effectively double the armor penetration of a gun when compared to full-caliber rounds such as Armor-piercing ammunition, AP, Armor-piercing shot and shell#Second World War, Armor-piercing Capped (APC), and APCBC, Armor piercing Capped Ballistic Cap (APCBC) projectiles. APDS-rounds were commonly used in large caliber tank guns up unt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
High-explosive Anti-tank
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD). The shaped charge jet armor penetration effect is purely kinetic in nature; the round has no explosive or incendiary effect on the armor. Unlike standard armor piercing shell, armor-piercing rounds, a HEAT warhead's penetration performance is unaffected by the projectile's velocity, allowing them to be fired by lower-powered weapons that generate less recoil. The performance of HEAT weapons has nothing to do with heat, thermal effects, with HEAT being simply an acronym. History HEAT warheads were developed during World War II, from extensive research and development into shaped charge warh ...

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. Some examples of smoothbore weapons are muskets, blunderbusses, and flintlock pistols. The opposite of smoothbore is rifling. 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Panther Tank
The Panther tank, officially ''Panzerkampfwagen V Panther'' (abbreviated Pz.Kpfw. V) with Sonderkraftfahrzeug, ordnance inventory designation: ''Sd.Kfz.'' 171, is a German medium tank of World War II. It was used in most European theatre of World War II, European theatres of World War II from mid-1943 to the end of the war in May 1945. 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. While having essentially the same Maybach V12 petrol (690 hp) engine as the Tiger I, the Panther had better gun penetration, was lighter and faster, and could traverse rough terrain better than the Tiger I. The trade-off was weaker side armour, which made it vulnerable to flanking fire, and a weaker high explosive shell. The Panther proved to be effective in open country and long-range engagements. The Panther had excellent firepower, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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. Since the 1990s, this type of document has proliferated in business. Today, a business-to-business (B2B) white paper falls under grey literature, more akin to a marketing presentation meant to persuade customers and partners, and promote a certain product or viewpoint. The term originated in the 1920s to mean a type of position paper or industry report published by a department of the UK government. Corporate and academic The most prolific publishers of white papers are corporate and academic organizations. In larger organizations, internal technical writers produce these documents based on the outlines and data an internal industry or academic expert develops and provides. White papers often follow strict industry styles and formats with a centr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
