[36] The T-72 also went through a modernization program in an attempt to bring it up to the standards of the T-80B. Austria, Canada, Chile, Denmark, Finland, Greece, Indonesia, the Netherlands, Norway, Poland, Portugal, Singapore, Spain, Sweden, Switzerland, Turkey. The PzH 2000 self-propelled howitzer is armed with Rheinmetall's L52 155 mm main gun. Although there were attempts to modify the 152-millimeter (6.0 in) tank gun to do so, the process proved extremely difficult, and the Germans began development of the future Rheinmetall 120 mm gun instead. [56] In 1998, the United States military introduced the M829A2, which has an improved depleted uranium penetrator and composite sabot petals. [52] The new ammunition has been accepted into service with the Dutch and Swiss, as well as German, armies.[53]. [15] The new tank concept also had improved armament, a 152-millimeter (6.0 in) missile-launching main gun, designed to fire the MGM-51 Shillelagh anti-tank missile. "New Tanks for the Old, Part II: Tank Top Upgrades". Between 1972 and 1975, a total of 17 prototypes were developed. Evaluated by the US Army between 1998 and 2001, this M1A2 featured a 120mm M256E1 gun with a new tube derived from the Rheinmetall L/55 found on the Leopard 2A6. Qty. An immediate improvement, known as the M829A1, was called the "Silver Bullet" after its good combat performance during the Gulf War against Iraqi T-55s, T-62s and T-72 tanks. The Leopard 2 and M1 Abrams (M1A1 and M1A2) are fitted with Rheinmetall's L44 and L55 120 mm tank gun. It was tested on the British Challenger 2 as a potential replacement for its current weapon, the rifled L30 120 mm cannon. The 120-millimetre (4.7 in) gun has a length of 5.28 metres (17.3 ft), and the gun system weighs approximately 3,317 kilograms (7,313 lb). The barrel has a calibre of 120 mm, and an overall length of 44 calibres (5.28 m). Fort Knox, KY: U.S. Armor Center. Is a Rheinmetall L55 120mm more powerful than a Rheinmetall L55 120mm, or even a 5-Inch/54-caliber (Mk 45) … [12] This case is similar to the American decision to replace the M68 105-millimeter (4.1 in) tank gun with Rheinmetall's 120 mm gun in 1976; the introduction of the T-64A had raised the question within the armor community whether the new ammunition for the existing gun caliber could effectively deal with the new Soviet tank. [12] This led Israel to opt for a 120 mm tank gun during the development process of the Merkava III main battle tank. Recent ammunition includes a wide range of new anti-personnel rounds and demolition munitions, giving tanks armed with the L/44 and its derivatives greater versatility on the modern battlefield. [58], The Israeli Army introduced a new round known as the Laser Homing Anti-Tank (LAHAT) projectile. [53], Both Germany and the United States have developed several other rounds. It's new 130mm design is shorter than the 120mm L55. [5] Ten of the 17 turrets built were equipped with the 105 mm smoothbore gun, and the other seven were equipped with the larger 120 mm gun. [62] This was later developed into the M830A1, which allows the M1 Abrams to use the round against helicopters. Muzzle of a Rheinmetall 120 mm L/55 tank gun on a Spanish Leopard 2E. 120 mm L44 Tank Gun As the standard NATO smoothbore gun for main battle tanks Leopard 2 and AbramsM1A1, Rheinmetall’s L44 tank gun proved superior to all rivals in the 120 mm arena. The Israelis also introduced a new anti-personnel munition which limits collateral damage by controlling the fragmentation of the projectile. We don't know about any in-box reviews for this Rheinmetall 120mm turned barrel with resin details L44/ L55 (#35074) from Inside the Armour. In-box reviews. [59] This variant is unofficially referred to by Abrams tank crews as the "super sabot". 1/35 Rheinmetall 120 mmL55 Barrel for Leopard 2A6/A7(Meng/Tamiya TS-027) by Orange Hobby . Although the gun is longer, allowing for a higher peak pressure from the propellant, the geometry remains the same, allowing the gun to fire the same ammunition as that fired from the shorter version. Maxwell, David (1 June 2002). [65] The M1A1 has also been exported to Australia,[66] while the M1A2 Abrams has been exported to Saudi Arabia and Kuwait.[67]. 1. Originally the gun ha… Jane's Armour & Artillery Upgrades (subscription). [13] This case is similar to the American decision to replace the M68 105-millimeter (4.1 in) tank gun with Rheinmetall's 120 mm gun in 1976; the introduction of the T-64A had raised the question within the armor community whether the new ammunition for the existing gun caliber could effectively deal with the new Soviet tank. The gun's barrel weighs 1,190 kilograms (2,620 lb), and on the M1 Abrams the gun mount weighs 3,317 kilograms (7,313 lb), while the new barrel (L/55) is 55 calibers long, 1.30 meters (4.3 ft) longer.The bore evacuator and the gun's thermal sleeve, designed to regulate the temperature of the barrel, are made of glass-reinforced plastic, while the barrel has a chrome lining to increase barrel life. [5] Originally the gun had a barrel life of between 400 and 500 rounds, but with recent advances in propellant technology the average life decreased to 260 rounds. Zaloga, Steven J.; (Lt. Col.) James W. Loop (1982). [17] This program grew into the Leopard 2; the first prototype of the new tank was delivered in 1972, equipped with a 105-millimeter (4.1 in) smoothbore main gun. The United States developed its own kinetic energy penetrator (KEP) tank round in the form of an Armor-Piercing Fin-Stabilized Discarding-Sabot (APFSDS) round, using a depleted uranium (DU) alloy long-rod penetrator (LRP), designated as the M829,[54] followed by improved versions. According to IHS Jane’s, Rheinmetall has proposed replacing the rifled L30A1 gun of the British Challenger 2 with the smoothbore L55 120mm gun. (1 January 2004). A variety of ammunition has been developed for use by tanks with guns based on Rheinmetall's original L/44 design. Originally, the Leopard 2 was outfitted with the DM23 kinetic energy penetrator,[44] based on the Israeli M111 Hetz. [36], The German government began the development of the Leopard 3, although this was canceled after the fall of the Soviet Union. L44. [54] The United States also has a MPAT type projectile, known as the M830. Rheinmetall's L/44 tank gun has a caliber of 120 mm, and a length of 44 calibers (5.28 meters (17.3 ft)). The introduction of the longer barrel came hand in hand with the introduction of a new kinetic energy penetrator, the DM53. [61] The United States also has a MPAT type projectile, known as the M830. Fort Knox, KY: U.S. Armor Center. [42] The new barrel weighs 1,347 kg (2,970 lb). The ammunition is manufactured by Zakłady Produkcji Specjalnej Sp. [57] In 2002, production began of the ($10,000 per round) M829A3 using a more efficient propellant (RPD-380 stick),[58] a lighter injection-molded sabot, and a longer (800mm) and heavier (10 kg / 22 lb) DU penetrator, which is said to be able to defeat the latest versions of Russian Kontakt-5 explosive reactive armor (ERA). [44] However, it has been found that the DM12's armor-killing abilities are limited by the lack of blast and fragmentation effects, and that the round is less valuable against lightly armored targets. [81] Although South Korean K2 Black Panther is equipped with a L/55 main gun and shows similar characteristics as its German counterpart, it is indigenously developed by Agency for Defense Development and World Industries Ace Corporation (WIA), a Korea-based powertrain company affiliated with Hyundai Kia Motors Group.[82]. Fogg, William; Robert Horner (1 May 1994). Recent ammunition includes a range of anti-personnel rounds and demolition munitions. The company was founded in 2006 and is part owned by Rheinmetall. [21], Rheinmetall's L/44 tank gun has a caliber of 120 mm, and a length of 44 calibers (5.28 meters (17.3 ft)). [31] Tanks armed with versions of Rheinmetall's gun produced under licence include Japan's Type 90[32] and South Korea's K1A1. [5] In 1965, the Soviet Union's T-62 made its first public appearance, armed with a 115-millimeter (4.5 in) smoothbore tank gun. [22], Rheinmetall's L/44 tank gun has a caliber of 120 mm, and a length of 44 calibers (5.28 meters (17.3 ft)). As the L/55 retains the same barrel geometry, it can fire the same ammunition as the L/44. [20] Another program aimed to mount the 152-millimeter (6.0 in) missile-gun was also developed in an attempt to save components from the MBT-70, but in 1971 the program was ended for economic reasons. [33] The gun had made a huge turn in technological history. [18] This program grew into the Leopard 2; the first prototype of the new tank was delivered in 1972, equipped with a 105-millimeter (4.1 in) smoothbore main gun. Military Guns and Ammunition - Rheinmetall improves 120mm L/55 - Not satisfied with developing a new 130mm gun, it seems that Rheinmetall is making some improvements to the 120mm L/55, intended for upgrading German and other current-model Leopards. "Improving the Leopard Firepower: More Potent Ammunition Prepares the Leopard to Face a Wide Spectrum of Missions". The cap allows the round to impact and embed itself in concrete, then exploding inside the target and causing more damage. Jane's Armour & Artillery Upgrades (subscription). The 120-millimeter (4.7 in) gun has a length of 5.28 meters (17.3 ft), and the gun system weighs approximately 3,317 kilograms (7,313 lb). [28], Two Leopard 2A6s of the German Army with L55s, The appearance of new Soviet tanks such as the T-80B during the late 1970s and early 1980s demanded the development of new technologies and weapons to counter the threat posed to Western armor. Furthermore, the missile can be fired by both 105-millimeter (4.1 in) and 120 mm tank guns. [37] On 29 October 1991, the governments of Switzerland, the Netherlands and Germany agreed to cooperate in the development of a modernization program for the Leopard 2. 120 mm Board Cannon and Ammunition of the Leapoard II Main Battle Tank of the German Armed Foreces [52] In 2002, production of the M829A3 began, which is said to be able to defeat the latest versions of Russian explosive reactive armor. Australia, Egypt, Iraq, Kuwait, Morocco, Saudi Arabia. The designation “L55… As the L/55 retains the same barrel geometry, it can fire the same ammunition as the L/44. Krauss-Maffei was chosen as the contractor, and two prototypes were developed in 1969 and 1970. Rheinmetall's L/44 tank gun has a caliber of 120 mm, and a length of 44 calibers (5.28 meters (17.3 ft)). Eshel, Tamir (1 February 2005). [66] The LAHAT has been offered as an option for the Leopard 2, and has been marketed by both Israel Military Industries and Rheinmetall to Leopard 2 users. The LAHAT, developed in Israel, is a gun-launched missile which has received interest from Germany and other Leopard 2 users, and is designed to defeat both land armour and combat helicopters. [61], Poland has introduced a series of projectiles for Rheinmetall's tank gun, including an armor-piercing penetrator target practice round (APFSDS-T-TP), a high-explosive round, and a high-explosive target practice (HE-TP) projectile.
