Royal Ordnance L30
The L30A1, officially designated Gun 120 mm Tk L30, is a 120 mm rifled tank gun used by the British Army and Royal Army of Oman. It is an improved production model of the Royal Ordnance L11 series of rifled tank guns. It is fitted in the turret of the Challenger 2 main battle tank, and has been retrofitted to the Challenger 1 tank. Challenger Armament The Challenger Armament (CHARM) project was intended to provide a new main armament for the Challenger 2 tank and to be retro-fitted to the Challenger 1. It involved three components: the gun, developed by the Royal Ordnance Factory, Nottingham, the depleted uranium (DU) APFSDS round, and a propellant charge for it. After earlier projects were cancelled, the EXP 32M1 experimental gun was re-titled the XL30E4 and accepted for production as the L30 in 1989. The Challenger 2 tank was first produced in 1993. Design The barrel is 55 calibres long (L55) and is made of electro-slag refined steel. The bore and chamber are e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ROF Nottingham
Royal Ordnance Factory (ROF) Nottingham opened in 1936 in The Meadows, Nottingham, United Kingdom. It was one of a number of Royal Ordnance Factories created in the build up to World War II. During the war the site employed up to four thousand workers. The factory was closed in 2001. It was at the site that had been used for manufacturing, mainly arms, since 1916.

Obturation Ring
{{Other uses, Obturator (other){{!Obturator An obturating ring is a ring of relatively soft material designed to obturate under pressure to form a seal. Obturating rings are often found in artillery and other ballistics applications, and similar devices are also used in other applications such as plumbing, like the ''olive'' in a compression fitting. The term "O-ring" is sometimes used to describe this kind of pressure seal. Ballistics uses Obturating rings are common in artillery, where the hard steel casing of the shell is too hard to practically deform to provide a tight seal for the propellant gases. An obturating ring or driving band made of a softer material is the typical solution. Mortar bombs also use obturating rings to provide a seal around the projectile. Recoilless rifles and some artillery use rings with a reverse impression of the rifling cut in them for a tighter seal even at very low pressures. Some artillery shells use an obturating ring at the rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheinmetall
Rheinmetall AG is a German automotive and arms manufacturer, headquartered in Düsseldorf, Germany. Its shares are traded on the Frankfurt stock exchange. History Rheinmetall was founded in 1889. Banker and investor Lorenz Zuckermandel Lorenz Zuckermandel (18 February 1847 – 6 January 1928) was a German banker, investor, founder and translator, among other things, of Dante Alighieri's Divine Comedy. Thanks to his many talents, he worked his way from being the poor son of a ... (1847–1928) was one of the founders and the first chairman of the supervisory board.

Rheinmetall Rh-120
The Rheinmetall Rh-120 is a 120 mm smoothbore tank gun designed and produced in former West Germany by the Rheinmetal-DeTec AG company, it was developed in response to Soviet advances in armour technology and development of new armoured threats. Production began in 1974, with the first version of the gun, known as the ''L/44'' as it was 44 calibres long, used on the German Leopard 2 tank and soon produced under license for the American M1A1 Abrams and other tanks. The gun has a length of , and the gun system weighs approximately . By 1990, the L/44 was not considered powerful enough to defeat future Soviet armour, which stimulated an effort by Rheinmetall to develop a better main armament. This first involved a tank gun named ''Neue Panzerkanone 140'' ('new tank gun 140'), but later turned into a compromise which led to the development of an advanced 120 mm gun, the L/55, based on the same internal geometry as the L/44 and installed in the same breech and mount.

2A46 125 Mm Gun
The 2A46 (also called D-81TM) is a 125 mm/L48 smoothbore cannon of Soviet origin used in several main battle tanks. It was designed by OKB-9 (Artillery Plant No. 9) in Yekaterinburg. Description It was developed by the Spetstekhnika Design Bureau in Ekaterinburg in the 1960s originally for the T-64 tank. They were subsequently manufactured at Artillery Plant No. 9 in Ekaterinburg and Motovilikha in Perm. Other variations include 2A46M, 2A46M-1, 2A46M-2, 2A46M-4, 2A46M-5, and Ukrainian KBA-3 and Chinese ZPT-98. The 2A46 can fire armour-piercing fin-stabilised discarding sabot (APFSDS), high-explosive anti-tank (HEAT) and high-explosive fragmentation (HEF) projectiles. The ammunition for the 2A46 gun is in two pieces: the projectile is loaded first, followed by a separate propellant charge. The early versions of the 2A46 suffered from a relatively short barrel life, but this was rectified on the 2A46M-1 version. Depending on the version it offers or from the 2A46M-1 Pma ...

MBT-80
The FV4601 MBT-80 was a British experimental third-generation main battle tank, designed in the late 1970s to replace the Chieftain tank. It was eventually (and later controversially) cancelled in favour of the Challenger 1, itself an evolution of the Chieftain design. History By the early 1970s, there was a great disparity in the number of tanks being fielded by NATO and the Warsaw Pact in Europe. The US Army fielded the M60 which had been designed to deal with the 100 mm gun of the T-55, but could not withstand the 115 mm gun being fielded on the T-62, let alone the newer 125 mm model of the T-64 and T-72. The same-era West German design, the Leopard 1, was very lightly armoured based on the conclusion that heavy armour had little purpose in an era of high-explosive anti-tank (HEAT) weapons of rapidly improving performance. The concept was to give the tank high manoeuvrability to allow it to outmanoeuvre the slower-moving Soviet tanks and early generation mis ...

Royal Ordnance L11
The Royal Ordnance L11A5, officially designated Gun 120 mm Tk L11, is a 120 mm L/55 rifled tank gun design. It was the first of NATO's 120 mm main battle tank guns which became the standard calibre for Western tanks in the later period of the Cold War. By 2005, a total of 3,012 L11 guns were produced. List price was US $227,000 (1990). The L11 was developed by Britain's Royal Ordnance Factories to equip the Chieftain tank as the successor to the 105 mm L7 gun used in the Centurion tank. It was also used on the Challenger 1, which replaced the Chieftain in British and Jordanian service. The weapon has been superseded by the L30 series 120 mm rifled tank gun. History The Royal Armament Research and Development Establishment at Fort Halstead designed a new 120 mm rifled tank gun in 1957. The new gun was deemed to be necessary because the British Army specified engagement ranges greater than those of other armies, for example , as specified by the US ...

White Phosphorus Weapon
White phosphorus munitions are weapons that use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke, illumination, and incendiary munitions, and is commonly the burning element of tracer ammunition. Other common names for white phosphorus munitions include ''WP'' and the slang terms ''Willie Pete'' and ''Willie Peter'', which are derived from ''William Peter'', the World War II phonetic alphabet rendering of the letters ''WP''. White phosphorus is pyrophoric (it is ignited by contact with air); burns fiercely; and can ignite cloth, fuel, ammunition, and other combustibles. In addition to its offensive capabilities, white phosphorus is a highly efficient smoke-producing agent, reacting with air to produce an immediate blanket of phosphorus pentoxide vapour. Smoke-producing white phosphorus munitions are very common, particularly as smoke grenades for infantry, loaded in defensive grenade launchers on tanks and other armoured v ...

High-explosive Squash Head
High explosive squash head (HESH) in British terminology, or high explosive plastic/plasticized (HEP) in American terminology, is a type of explosive projectile which uses a plastic explosive that conforms to the surface of a target before detonating, to improve the transfer of explosive energy to the target. Squash head projectiles are similar to high explosive projectiles and are well suited to many of the same targets. However, while HESH projectiles are not armour-piercing, they can defeat armored targets by causing spall which can injure or kill a vehicle's occupants, and detonate some types of ammunition. Design Function HESH rounds are thin metal shells filled with inert material (like coal-tar pitch), plastic explosive and a delayed-action base fuze. On impact, the inert material, followed by plastic explosive, is "squashed" against the surface of the target and spreads out to form a disc or "pat" of explosive. The inert material helps prevent premature detonation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
