Steyr IWS 2000
The Steyr IWS 2000 is an Austrian single-shot bolt-action anti-materiel rifle produced by Steyr Mannlicher. IWS stands for Infantry Weapon System. Like many anti-tank rifles, it is actually a smoothbore weapon and not a true rifle. This can help accelerate projectiles and increase ballistic effectiveness, but the lack of rifling imparting inertial stability requires the projectile to have stabilizing fins. It is chambered in a 15.2×169 mm armor-piercing fin-stabilized discarding-sabot cartridge, and is the first man-portable rifle to use this type of ammunition. The first variant of the weapon was the proposed AMR 5075 (AMR standing for anti-materiel rifle). It was to fire the same type of ammunition as the IWS 2000 and to use a 5-round detachable box magazine. However, that version did not pass the proposal stage. Design The weapon is based on a long recoil mechanism. This mechanism, usually found in shotguns, helps manage the heavy recoil forces of the 15.2 mm Steyr APFS ...

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

GIAT LG1
The LG1 is a modern 105 mm towed howitzer designed and produced by GIAT Industries (now Nexter group) of France. Design The LG1 howitzer is a 105 mm towed artillery piece that features both low weight and a high level of accuracy over long distances. Its lightweight construction gives the barrel a relatively short lifespan. The equivalent full charge (EFC) count is suggested to be approximately 7,500; however, during fire and practice, has yielded only around 1,500 EFCs. The gun was specifically designed for use by rapid deployment forces with attributes such as ruggedness, ease of operation and reduced weight. It can fire all NATO standard 105 mm ammunition up to a range of using HE-ER G3 base bleed rounds. Deployment The gun has been used by the Belgian Army, Canadian Army, Colombian National Army, Indonesian Marine Corps, Singapore Army and the Royal Thai Army. Current service version with Canadian artillery is the LG1 Mark II, of which 28 were purchased for the R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sniper Rifles Of Austria
A sniper is a military/paramilitary marksman who engagement (military), engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with sniper rifle, high-precision rifles and high-magnification telescopic sight, optics, and often also serve as reconnaissance, scouts/forward observer, observers feeding tactical information back to their units or command headquarters. In addition to long range shooting, long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, Military camouflage, camouflage, Tracking (hunting), tracking, bushcraft, field craft, infiltration tactics, infiltration, special reconnaissance and observation, surveillance and target acquisition. Etymology The name "sniper" comes from the verb "to snipe", which originated in the 1770s among soldiers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flechette Firearms
A flechette ( ) is a pointed steel projectile with a vaned tail for stable flight. The name comes from French , "little arrow" or "dart", and sometimes retains the acute accent in English: fléchette. They have been used as ballistic weapons since World War I. Delivery systems and methods of launching flechettes vary, from a single shot, to thousands in a single explosive round. The use of flechettes as antipersonnel weapons has been controversial. Air-dropped During World War I, flechettes were dropped from aircraft to attack infantry and were able to pierce helmets. Later the U.S. used Lazy Dog bombs, which are small, unguided kinetic projectiles typically about in length, in diameter, and weighing about . The weapons were designed to be dropped from an aircraft. They contained no explosive charge but as they fell they developed significant kinetic energy making them lethal and able to easily penetrate soft cover such as jungle canopy, several inches of sand or light armo ...

Sabot (firearms)
A sabot (, ) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/shotgun slug, slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel (firearms), barrel when fired. It allows a narrower projectile with high sectional density to be fired through a gun barrel, barrel of much larger caliber, bore diameter with maximal acceleration, accelerative transfer of kinetic energy. After leaving the muzzle (firearms), muzzle, the sabot typically separates from the projectile in flight, diverting only a very small portion of the overall kinetic energy. The sabot component in projectile design is the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than t ...

Rolled Homogeneous Armor
Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks. After World War II, it began to fall out of use on main battle tanks and other armoured fighting vehicles intended to see front-line combat as new anti-tank weapon technologies were developed which were capable of relatively easily penetrating rolled homogeneous armour plating even of significant thickness. Today, the term is primarily used as a unit of measurement of the protection offered by armour on a vehicle (often composed of materials that may not actually contain steel, or even contain any metals) in equivalent ''millimetres of RHA'', referring to the thickness of RHA that would provide the same protection. Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protectiv ...

Depleted Uranium
Depleted uranium (DU; also referred to in the past as Q-metal, depletalloy or D-38) is uranium with a lower content of the fissile isotope than natural uranium.: "Depleted uranium possesses only 60% of the radioactivity of natural uranium, having been 'depleted' of much of its most highly radioactive U234 and U235 isotopes." Natural uranium contains about , while the DU used by the U.S. Department of Defense contains or less. The less radioactive and non-fissile constitutes the main component of depleted uranium. Uses of DU take advantage of its very high density of ( denser than lead). Civilian uses include counterweights in aircraft, radiation shielding in medical radiation therapy and industrial radiography equipment, and containers for transporting radioactive materials. Military uses include armor plating and armor-piercing projectiles. Most depleted uranium arises as a by-product of the production of enriched uranium for use as fuel in nuclear reactors and in the ...

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". Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymers
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'', meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
122 Mm Howitzer 2A18 (D-30)
The 122-mm howitzer D-30 ( GRAU index 2A18) is a Soviet howitzer that first entered service in 1960. It is a robust piece that focuses on the essential features of a towed field gun suitable for all conditions. The D-30 has a maximum range of 15.4 kilometers, or over 21 km using rocket-assisted projectile ammunition. With its striking three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the nations of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces. The barrel assembly of the 2A18 gun is used by the 2S1 self-propelled howitzer. There are also Egyptian, Chinese, Serbian and Syrian self-propelled variants and conversions. The Syrian conversion utilizes the hull of a T-34 tank. History The 122 mm (originally 48 lines) calibre was adopted by Russia in the early 20th century, becoming very important to Soviet artil ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article on Limcat Under ...
