77-512: 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 140-millimeter (5.5 in) 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

154-578: A 20-millimetre (0.79 in) autocannon as secondary armament, an active hydropneumatic suspension and spaced armour on the glacis plate and front turret. The new tank concept also had improved armament, a 152-millimetre (6.0 in) missile-launching main gun, designed to fire the MGM-51 Shillelagh anti-tank missile . However, the German Army was interested in a tank gun which could fire conventional ammunition. Although there were attempts to modify

231-597: A 50% longer kill range compared to their 120 mm cannon with a higher rate of fire due to a fully automated ammunition handling system. The M256 is an American variant that uses a Rh-120 L44 gun tube and combustible cartridges with an American-designed mount, cradle and recoil mechanism. It is primarily used by the M1 Abrams main battle tank. The M256 differs from the Rh-120 L44 in several aspects: A variety of rounds have been developed for Rheinmetall's tank gun. For example,

308-495: A DU particle-free environment. South Korea holds related patents on Japan, United Kingdom, United States, and 3 other unspecified nations. The public appearance of the K276 armour-piercing fin-stabilized discarding sabot (APFSDS), the first 120 mm ammunition with self-sharpening penetrator, was during the release ceremony of K1A1 prototype in 1996. The United States developed its own kinetic energy penetrator (KEP) tank round in

385-643: A Korea-based powertrain company affiliated with Hyundai Kia Motors Group. Leopard 2E The Leopardo 2E or Leopard 2A6E ( E stands for España ( Spanish for 'Spain')) is a variant of the German Leopard 2 main battle tank (specifically the Leopard 2A6 variant), tailored to the requirements of the Spanish army , which acquired it as part of an armament modernization program named Programa Coraza , or Program Cuirass . The acquisition program for

462-501: A chrome-lined smoothbore barrel (initially L/51, revised to L/52) with a vertical sliding breech mechanism, increased chamber volume, no muzzle brake , a thermal sleeve , and a muzzle reference system (MRS) enabling it to be boresighted on a more regular basis without the crew needing to leave the platform. Compared to the 2,700 kg (6,000 lb) 120 mm gun, the 130 mm has a 1,400 kg (3,100 lb) barrel and an all-up weight of 3,000 kg (6,600 lb) including

539-552: A constant pattern of expansion between ambient temperatures inside the gun barrel from −47 °C (−53 °F) to +71 °C (160 °F). The new propellant powders, known as surface-coated double-base (SCDB) propellants, allow the DM63 to be used in many climates with consistent results. The new ammunition has been accepted into service with the Dutch and Swiss, as well as German, armies. In 1993, South Korea invented self-sharpening process on

616-607: A full-rate production in December 2015. Both Germany and the United States have developed several other rounds. These include the German DM12 multi-purpose anti-tank projectile (MPAT), based on the technology in a high-explosive anti-tank (HEAT) warhead. However, it has been found that the DM12's armour-killing abilities are limited by the lack of blast and fragmentation effects, and that

693-747: A high-explosive target practice (HE-TP) projectile. The ammunition is manufactured by Zakłady Produkcji Specjalnej Sp. z o.o. In early 2013 Rheinmetall announced two new rounds suitable for the L44 and the L55 guns, the DM11 HE round, designed for lightly armoured targets, field fortifications and targets behind cover and a lower cost alternative to the DM11, the HE SQ Rh31. In April 2024, the British Ministry of Defence announced that

770-656: A long line of armour-piercing discarding sabot (APDS) rounds was developed by Rheinmetall. Originally, the Leopard 2 was outfitted with the DM23 kinetic energy penetrator, based on the Israeli 105 mm M111 Hetz which itself was a licensed copy of the American M735 round. The DM23 was eventually replaced by the DM33, which was also adopted by Japan, Italy, Netherlands and Switzerland. The DM33 has

847-490: A more powerful gun was needed for its new tanks. The first instance of a larger Soviet tank gun was witnessed on the chassis of a modified T-55 in 1961. In 1965, the Soviet Union 's T-62 made its first public appearance, armed with a 115-millimetre (4.5 in) smoothbore tank gun. The Soviet decision to increase the power of its tank's main armament had come when, in the early 1960s, an Iranian tank commander defected over

924-524: A new demolition round, called the M908 obstacle defeating round , based on the M830A1 MPAT, but with the proximity fuse replaced by a hardened nose cap. The cap allows the round to impact and embed itself in concrete, exploding inside the target and causing more damage. The Israeli Army introduced a new round known as the laser homing anti-tank ( LAHAT ) projectile. Using a semi-active laser homing guidance method,

1001-604: A new tank gun, increasing the maximum range of the gun by an estimated 1,500 m (1,600 yd). Although the gun is longer, allowing for longer and 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. The longer barrel allows ammunition to attain higher velocities; for example, with new kinetic energy penetrators ammunition can reach velocities of around 1,750 m/s (5,700 ft/s). The new barrel weighs 1,347 kg (2,970 lb). The longer tank gun has been retrofitted into

1078-638: A partnership with Santa Bárbara Sistemas, GIAT with what became the Leclerc , General Dynamics with the M1 Abrams and Vickers with the Valiant. While the M1 ;Abrams and Valiant bids were not accepted, the bidding continued until 1989 when it was officially canceled. Instead, the Spanish government opted to replace its older Patton tanks with American M60 Patton tanks retired from Central Europe in accordance with

1155-455: A round known as the APAM , which is an anti-personnel munition designed to release fragmentation at controlled intervals to limit the extent of damage. Fragments are shaped to have enough kinetic energy to penetrate body armour. Poland has introduced a series of projectiles for Rheinmetall's tank gun, including an armour-piercing penetrator target practice round (APFSDS-T-TP), a high-explosive round, and

1232-403: A statement of intent had been signed with Germany for the development of an Enhanced Kinetic Energy (EKE) armour-piercing round for both Challenger 3 and Leopard 2 tanks, as a joint venture between Rheinmetall and BAE Systems . Due to tank sales, Rheinmetall's L/44 tank gun has been manufactured for other nations. For example, the Leopard 2 armed with the 44 calibre long gun, has been sold to

1309-513: A successor to the Leopard 2 and Leclerc , possibly to be launched between 2025 and 2030. In July 2020, Rheinmetall unveiled a testbed tank for the gun in a new turret, mounted on a Challenger 2 hull. In June 2022, Rheinmetall unveiled the Panther KF51 concept tank based on a Leopard 2 chassis and a redesigned turret hosting the new gun. According to Rheinmetall the Rh-130 ;mm cannon enables

1386-455: A three-part aluminium sabot and a two-part tungsten penetrator, and is said to be able to penetrate 470 millimetres (19 in) of steel armour at a range of 2,000 metres (2,200 yd). The DM43 is a further development of this round, codeveloped between Germany and France. The introduction of the longer barrel came together with the introduction of a new kinetic energy penetrator, the DM53 . With

1463-459: Is a gun-launched anti-tank guided missile which has received interest from Germany and other Leopard 2 users. It is designed to defeat both land armour and combat helicopters. The Israelis also introduced a new anti-personnel munition which limits collateral damage by controlling the fragmentation of the projectile. The development of the 120 mm L/44 gun started in 1965, as the Bundeswehr felt

1540-498: Is one of the best-protected Leopard 2s in service. The tank is armed with Rheinmetall 's 120-millimeter (4.7 in) L/55 tank-gun , and is capable of adopting a 140-millimeter (5.5 in) gun. Both the tank commander and gunner have identical second-generation thermal viewers, derived from those of the TOW 2B Light Launcher System. These are integrated into the tank by Indra and Rheinmetall Defense Electronics . Indra provides

1617-460: Is one of the most expensive Leopard 2s built; the original contract was worth €1,910m but the final cost was €2,399m. The Spanish army replaced its M60 Patton tanks and AMX-30s with the Leopard ;2 between 1995 and 2008, a considerable improvement in capability. Previously, the Spanish army was equipped with M47 and M48 Patton tanks, which were upgraded to near M60 equivalency during

1694-639: Is said to be able to defeat the latest versions of Russian Kontakt-5 explosive reactive armour (ERA). This variant is unofficially referred to by Abrams tank crews as the "super sabot". In response to the M829A3, the Russian Army designed the Relikt , the most modern Russian ERA, which is claimed to be twice as effective as the Kontakt-5. A further improved M829A4 round with a segmented penetrator to defeat Relikt has entered

1771-612: The Alcántara Armored Cavalry Regiment, based in Melilla . Spain's Leopard 2E is based on the Leopard 2A6 , and incorporates the add-on wedge armor of the Leopard 2A5 on the turret. This armor maximizes the armor depth that a kinetic energy penetrator must travel through to enter the internal volume of the turret. Like the Swedish Leopard 2S ( Strv 122 ), the Leopard 2E has increased armor thickness on

1848-512: The Eurocopter Tiger attack helicopter. The program's scope extended to the integration of 108 Leopard 2A4s, which were leased to Spain in late 1995. Apart from procurement, Programa Coraza was meant to prepare the Spanish army logistically for the introduction of new matériel. A memorandum of understanding was signed on 9 June 1995 between the German and Spanish governments, setting

1925-596: The German army after the reunification of Germany , the Spanish government declined these offers and pressed for the Leopard 2. In March 1994, the Spanish Ministry of Defense created Programa Coraza 2000 (Program Breastplate 2000), which focused on the procurement and integration of new armament for the Spanish army's modernization. The program included the Leopard 2E and the Pizarro infantry combat vehicle , as well as

2002-454: The Leopard 2 ; the first prototype of the new tank was delivered in 1972, equipped with a 105-millimetre (4.1 in) smoothbore main gun. Between 1972 and 1975, a total of 17 prototypes were developed. The new 120 mm gun's ten-year development effort ended in 1974. Ten of the seventeen turrets built were equipped with 105 mm smoothbore guns, and the other seven were equipped with larger, 120 mm, guns. Another program aimed to mount

2079-470: The M1 Abrams the gun mount weighs 3,317 kilograms (7,313 lb), while the new barrel (L/55) is 55 calibres long, 1.30 metres (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. Originally the gun had an EFC barrel life of ~1,500 rounds, but with recent advances in propellant technology,

2156-627: The M60-2000 main battle tank which would upgrade older M60 Patton tanks to have capabilities of their M1A1 Abrams at a reduced cost, though the company has not yet found a buyer. The Leopard 2A6 and its longer L/55 main gun have been exported for use by the Canadian Army , and the Netherlands upgraded part of its original fleet of Leopard 2s with the more powerful armament. The British Army has tested Rheinmetall's longer gun, possibly looking to replace

2233-570: The Treaty on Conventional Armed Forces in Europe . Although the Spanish army was originally to receive 532 M60 and M60A1 tanks, only 260 M60A3s were ultimately delivered, of which 244 were put into active service in the army. In the late 1980s the Spanish Ministry of Defense approved a modernization program for 150 of its AMX-30Es and a reconstruction program for the remaining 149 vehicles of this type, restoring them to their original condition. However, neither

The Leopard 2E is expected to remain in service until 2025. By 1987, the Spanish army was equipped with 299 French-designed AMX-30Es , assembled by Santa Bárbara Sistemas, and 552 American M47 and M48 Patton tanks. The AMX-30Es were put into service in 1970, while

2387-578: The 152-millimetre (6.0 in) missile-gun was also begun in an attempt to save components from the MBT-70, but in 1971 the program was ended for economic reasons. Instead, the Germans opted for Rheinmetall's 120 mm L/44 smoothbore tank gun. Rheinmetall's L/44 tank gun has a calibre of 120 mm, a length of 44 calibres (5.28 metres (17.3 ft)), and a chamber volume of 10.2 liters (622.44 in). The gun's barrel weighs 1,190 kilograms (2,620 lb), and on

2464-597: The 152-millimetre (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. In 1967, the German ministry of defence decided to re-open a Leopard 1 improvement program, known as the Vergoldeter Leopard ('Gilded Leopard'), later renamed the Keiler ('Wild Boar'). Krauss-Maffei was chosen as the contractor, and two prototypes were developed in 1969 and 1970. This program grew into

2541-467: The 1960s, KraussMaffei built several examples of the ML 4000 C′C′ diesel-hydraulic locomotive for demonstration and testing on American railroads. Southern Pacific and Denver & Rio Grande Western Railroad participated in the tests, but both found the locomotives unsuitable for service in the rugged Rocky Mountains through which the two railroads ran. KrausMaffei was a major tank manufacturer. In 1963

2618-541: The 1970s, KraussMaffei were involved in the development of the Transrapid magnetic levitation train. In 1986 the plastics equipment division was separated and became Krauss-Maffei Kunststofftechnik GmbH. Mannesmann acquired majority share of KraussMaffei in 1989, and bought out the remaining shares in 1996. In 1999 KraussMaffei merged with Demag to form the Mannesmann Demag Kraus-Maffei . In 1999

2695-409: The 43 Leopard 2Es to be delivered to the Spanish army were actually delivered—with 15 more being delivered before the end of the year to make up for the earlier production problems. By 1 July 2006 the Spanish army had received 48 Leopard 2Es and nine Büffel armored recovery vehicles , which was only a quarter of those contracted. Production of the Leopard 2E was planned to end by 2007 but

Although the American M1 Abrams was originally armed with the M68A1 105 mm gun (a version of the L7), the United States Army had planned to fit the tank with a larger main gun at a later date, and the tank's turret had been designed to accommodate a larger 120 mm gun. The larger gun was integrated into the M1A1 Abrams, with the first vehicle coming off

2926-472: The KrausMaffei trademarks following dissolution of Mannesmann Group. In 2016, KraussMaffei (by then only a plastics manufacturer) was purchased by ChemChina . In November 2018 KraussMaffei was the victim of a ransomware attack, leading to severe drawdown in the production. After the transaction, ChemChina held a good 60 percent of the shares, another Chinese sovereign wealth fund around 15 percent, and

3003-520: The L/44 and installed in the same breech and mount. The L/55 is 1.32 metres (4.3 ft) longer, generating increased muzzle velocity for rounds fired through it. As the L/55 retains the same barrel geometry, it can fire the same ammunition as the L/44. The L/55 gun was retrofitted into German and Dutch Leopard 2s, and chosen as the main gun of the Spanish Leopard 2E and the Greek Leopard 2HEL. It

3080-567: The LAHAT can be guided by the tank's crew or by teams on the ground, while the missile's trajectory can be selected to either attack from the top (to defeat enemy armour) or direct attack (to engage enemy helicopters). Furthermore, the missile can be fired by both 105-millimetre (4.1 in) and 120-millimetre (4.7 in) tank guns. 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. Israeli Merkavas make use of

3157-641: The Leopard 2, creating a model known as the Leopard 2A6 . The Spanish Leopard 2E , the Greek Leopard 2HEL, and derivatives of the Leopard 2A6, use 55 calibre-long tank guns. The Rh-120-55 A1 is similar to earlier Rh-120 L/55 model. Compared to the L/44 and L/55, the L/55 A1 Extreme Service Condition Pressure (ESCP) is raised from 672 to 700 MPa (97,465 to 101,526 psi), the Permissible Maximum Pressure (PMP) from 710 to 735 MPa (102,977 to 106,603 psi), and

Despite postponement of production owing to the 2003 merger between Santa Bárbara Sistemas and General Dynamics , and continued manufacturing issues between 2006 and 2007, 219 Leopard 2Es have been delivered to

3311-520: The M60A3. Background: History of the tank , Tank classification Krauss-Maffei KraussMaffei is a German manufacturing company. It is a manufacturer of injection molding machines, machines for plastics extrusion technology, and reaction process machinery. It was acquired by ChemChina in 2016. KraussMaffei was formed in 1931 from a merger of the two Munich firms of Maffei (founded 1838) and Krauss & Co. (founded 1860). Both belonged to

3388-555: The M60s nor the AMX-30s were a considerable improvement over Spain's fleet of M47 and M48 Patton tanks. Since the existing tank fleet did not meet the Spanish army's needs, Spain opened talks with Germany and Krauss-Maffei over the possibility of future collaboration in regards to Spain's future tank, and sent a military delegation to Germany in 1994. Although the Germans offered Spain surplus Leopard 1 tanks and Soviet equipment incorporated into

3465-722: The Netherlands, Switzerland, Sweden, Spain, Austria, Denmark, Finland, and other countries. Egypt had manufactured 700–800 M1A1 Abrams by 2005, and in 2008 requested permission to build another 125 tanks; their M256 main guns (the US version of the L/44) were manufactured by the Watervliet Arsenal . The M1A1 has also been exported to Australia, while the M1A2 Abrams has been exported to Saudi Arabia and Kuwait. The American license-built M256 has also been offered by General Dynamics Land Systems as part of

3542-622: The Soviet border in a brand-new M60 Patton tank, which was armed with the 105-millimetre (4.1 in) M68 gun, the US version of the British Royal Ordnance L7. Despite the introduction of the T-62, in 1969 their T-64 tank was rearmed with a new 125-millimetre (4.9 in) tank gun, while in 1972 Nizhny Tagil began production of the T-72 tank, also armed with the 125-millimetre (4.9 in) gun. At

3619-641: The Spanish army. The Leopard 2E is superior to the M60 Patton tank, which it replaced in Spain's mechanized and armored units. Its development represented a total of 2.6 million man-hours ' worth of work, 9,600 of them in Germany, at a total cost of 2.4 billion euros . This makes it one of the most expensive Leopard 2s built. Indigenous production amounted to 60% and the vehicles were assembled locally at Sevilla by Santa Bárbara Sistemas. It has thicker armor on

3696-549: The T-80B during the late 1970s and early 1980s led to the development of new technologies and weapons to counter the threat posed to Western armour. The T-80B had increased firepower and new composite ceramic armour . The T-72 also went through a modernization program in an attempt to bring it up to the standards of the T-80B. In 1985 the new T-72B version entered production, with a new laminate armour protection system; its turret armour, designed mainly to defeat anti-tank missiles, surpassed

3773-471: The T-80B's in protection. The German government began developing the Leopard 3, although this was canceled after the fall of the Soviet Union. 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. Part of this program included the introduction of a longer 120 mm tank gun, a cheaper alternative to

3850-429: The average life has increased even further. The gun's recoil mechanism is composed of two hydraulic retarders and a hydropneumatic assembly. Production of the German Leopard 2 and the new 120 mm tank gun began in 1979, fulfilling an order for the German Army. The L/44 Extreme Service Condition Pressure (ESCP) is 672 MPa (97,465 psi), the Permissible Maximum Pressure (PMP) 710 MPa (102,977 psi), and

4004-484: The company started production of the Leopard tank . Development and production of Leopard 2 tank started in 1972 in cooperation with Wegmann & Co . The "tank family" comprised not only main battle tanks, but also combat engineering vehicles, air defense tank Flakpanzer Gepard , self-propelled howitzer Panzerhaubitze 2000 (PzH 2000), and reconnaissance and transportation vehicles. More than 10,000 armoured vehicles based on Leopard tanks were produced since 1960s. In

4081-578: The current L30A1 120 mm L/55 rifled main gun on the Challenger 2 . Two Challenger 2s were modified to undergo firing trials. Although the South Korean K2 Black Panther is equipped with a CN08 120 mm L/55 main gun and is often misunderstood as a licensed product of the German counterpart due to its similar appearance of the gun barrel, it is indigenously developed by Agency for Defense Development (ADD) and WIA (Now Hyundai WIA ),

4158-524: The defence component was spun off and merged with Wegmann & Co to become Krauss-Maffei Wegmann (KMW). Co-operation between companies was already well established, with Wegmann supplying tank turrets, among other things. After acquisition of Mannesmann's telecommunication business by Vodafone in February 2000, Mannesmann group was dissolved. KraussMaffei's locomotive production and defense division Krauss-Maffei Wegmann were bought by Siemens AG . In 2000 Krauss-Maffei Kunststofftechnik GmbH took over

4235-432: The fighting at Sultan Yakoub, during the 1982 Lebanon War , the Israeli government claimed to have destroyed nine Syrian T-72s with the Merkava main battle tank, armed with an Israeli version of the American M68 105-millimetre (4.1 in) tank gun. Whether true or not, the Soviets test-fired a number of Israeli M111 Hetz armor-piercing discarding sabot rounds at Kubinka , finding the 105-millimetre (4.1 in) round

4312-453: The form of an APFSDS round, using a DU alloy long-rod penetrator (LRP), designated the M829 , followed by improved versions. An immediate improvement, known as the M829A1 , was called the "Silver Bullet" after its good combat performance during the Gulf War against Iraqi T-55 , T-62 and T-72 tanks. The M829 series centres around the depleted uranium penetrator, designed to penetrate enemy armour through kinetic energy and to shatter inside

4389-499: The foundations for an acquisition of up to 308 brand-new Leopard 2Es. These were to be assembled in Spain by Santa Bárbara Sistemas, with 60–70 percent of the components manufactured by Spanish companies, and production taking place between 1998 and 2003. Furthermore, the German government agreed to lend the Spanish army 108 Leopard 2A4s for training purposes for a period of five years. These vehicles were delivered between November 1995 and June 1996. In 1998, Spain agreed to procure

4466-403: The hull's glacis plate, the turret frontal arc and the turret roof, bringing the vehicle's weight close to 63  tonnes (69.4  tons ). The vehicle's protection is augmented by the added armor that is built into the tank during the manufacturing process, as opposed to being added on after assembly as is the case for German Leopard 2A5s and 2A6s. As a consequence, the Leopard 2E

4543-615: The increase of 8% in calibre resulting in 50% more kinetic energy over the 120 mm gun. The chamber volume was increased by 50% compared to the 120 mm gun in the first 130 mm demonstrator gun, but is subject to further refinement. Comparing pressure levels in the 120 mm L/55 A1 gun and in the 130 mm prototype, Extreme Service Condition Pressure climbs from 700 to 800 MPa (101,526 to 116,030 psi), Permissible Maximum Pressure from 735 to 850 MPa (106,603 to 123,282 psi), and Design Pressure from 760 to 880 MPa (110,229 to 127,633 psi). Engineers believe

4620-403: The introduction of the T-64A had raised the question within the armour community of whether the new ammunition for the existing gun calibre could effectively defeat the new Soviet tank. In 1963, Germany and the United States had already embarked on a joint tank program, known as the MBT-70 . The new tank carried a crew of three, with the driver in the turret, an automatic loader for the main gun,

4697-401: The irregular Spanish terrain. About 60% of each Leopard 2E was manufactured in Spain, as opposed to 30% for the Swedish Leopard 2s, for example. Although the final contract for the production of Spanish Leopard 2Es was signed in 1998, calling for a production rate of four tanks per month, the first Leopard 2Es were not manufactured until late 2003. This was largely due to

4774-404: The late 1970s and during the 1980s. Both the Leopard 2A4 and Leopard 2E sport a much more powerful gun than the AMX-30 and M60 tanks. The Leopard 2's 1,500 horsepower (1,100 kW) engine provides greater power than the M60A3's 750 hp (560 kW) and the AMX-30EM2's 850 hp (630 kW) engines. On the other hand, the Leopard 2 carries fewer, but larger, rounds than

4851-474: The latter went into service in the mid-1950s. Although Spain's M47s and M48s were modernized to M47Es and M48Es, bringing them to near equivalence with the M60 Patton tank, the Spanish army considered them antiquated. In 1984, when deciding to replace its Patton tanks, the Spanish government declared its intention to produce a whole new main battle tank locally, since known as the Lince . Five companies expressed interest in bidding, including Krauss-Maffei in

4928-417: The leading German makers of locomotives of various types. Maffei also built other steam-operated vehicles and, later, manufactured vehicles with combustion engines, including locomotives, trolleybuses and buses until the 1950s. The headquarters of the firm remained in Munich. KrausMaffei had produced injection moulding equipment since 1957. In 1964 the company Eckert & Ziegler GmbH was taken over. In

5005-414: The merging of Santa Bárbara Sistemas with General Dynamics , and Krauss-Maffei's reservations regarding the sharing of the Leopard 2's technology with a rival company manufacturer of the M1 Abrams . Krauss-Maffei delivered 30 Leopard 2Es between 2003 and 2006. Production by Santa Bárbara Sistemas was delayed after assembly had begun; between January and November 2007, for example, only three of

5082-596: The production line in 1985 The gun, known as the M256 , was based on the L/44 tank gun, although manufactured at Watervliet Arsenal . Tanks armed with versions of Rheinmetall's gun produced under licence include Japan's Type 90 and South Korea's K1A1 . The M256 based on the L/44 when firing M829A1 Armor Piercing, Fin Stabilized, Discarding Sabot - Tracer (APFSDS-T) ammunition can attain a Peak Chamber Pressure of 661.9 MPa (96,000 psi) at 49 °C (120 °F) and 569.85 MPa (82,650 psi) at 21 °C (70 °F). The appearance of new Soviet tanks such as

5159-405: The projectile including sabot weighing 8.35 kilograms with a 38:1 length to diameter ratio and with a muzzle velocity of 1,750 metres per second (5,700 ft/s), the DM53 has an effective engagement range of up to 4,000 metres (4,400 yd). A further development, called the DM63 , improved upon the round by introducing a new temperature-independent propellant, which allows the propellant to have

5236-400: The recoil system. Rheinmetall is developing a new generation APFSDS round featuring a semi-combustible cartridge case, new propellant, and new advanced long rod tungsten penetrator, and a high-explosive air-bursting munition (HE ABM) based on the 120 mm DM11 HE ABM in parallel with the gun. The cartridges of 130 x 850 mm are 30 kg (66 lb) and 1.3 m (4.3 ft) long with

5313-443: The rest was free float. At the same time, production in China was stepped up: In addition, the ChemChina majority holding Qingdao Tianhua Institute of Chemistry Engineering (THY) took over a ChemChina plant in Sanming , which builds injection molding machines for the Chinese market. Starting in 2022, the company will relocate its headquarters and location in Allach in phases to an industrial estate currently under construction in

5390-426: The round is less valuable against lightly armoured targets. The United States also has an MPAT-type projectile, named M830 . This was later developed into the M830A1, which allows the M1 Abrams to use the round against helicopters. The M1 Abrams can use the M1028 canister round, which is an anti-personnel-anti-helicopter munition, packed with over 1,000 10 mm tungsten balls. The United States Armed Forces accepted

5467-408: The tank's command and control system, called the Leopard Information and Command Equipment (LINCE), based on the Swedish and German Integrierte Führungssysteme (IFIS). Other differences between the Spanish Leopard 2E and other Leopard 2A6s include an auxiliary power unit , manufactured by SAPA, an air-conditioning system and new rubber pads for the vehicle's tracks to increase their lifespan on

5544-587: The tungsten heavy alloy (WHA), which the process was only achievable from depleted uranium (DU) penetrators, by applying microstructure control and multi-stage cyclic heat-treatment . Most penetrators in the world receive a single heat treatment, while Korean penetrators are treated 20 times using the new technology, which increases impact toughness by 300%. The self-sharpening effect increases penetration by 8–16% compared to regular penetrators, and compensates 6–10% less penetration from material disadvantage against DU, providing firepower of that of DU ammunition in

5621-468: The turret, doing much damage within the tank. In 1998, the United States military introduced the M829A2, which has an improved depleted uranium penetrator and composite sabot petals. In 2002, production began of the ($ 10,000 per round) M829A3 , using a more efficient propellant (RPD-380 stick), a lighter injection-molded sabot, and a longer (800 mm) and heavier (10 kg / 22 lb) DU penetrator, which

5698-514: The weapon can only be used with an automatic loader and new turret design. The gun commenced static firing trials at Rheinmetall's proving ground following Eurosatory, while engineers hoped to receive a new NATO standard by the end of 2016, although development of the gun and ammunition will likely take 8–10 years. The 130 mm is designed to equip the Main Ground Combat System (MGCS), a joint effort between Germany and France to produce

5775-713: Was able to perforate the sloped front section plate but not the turret armour of the T-72 tank. In response, the Soviets developed the T-72M1. This led Israel to opt for a 120 mm tank gun during the development process of the Merkava ;III main battle tank. This case is similar to the American decision to replace the M68 105-millimetre (4.1 in) tank gun with Rheinmetall's 120 mm gun in 1976;

5852-428: Was extended into 2008. The Leopard 2E replaced the Leopard 2A4 in Spanish mechanized units, which in turn replaced M60s in cavalry units. Both versions of the Leopard 2 are expected to remain in service with the Spanish army until 2025. In terms of industrial scale, the production and development of the Leopard 2E represents a total of 2.6 million man-hours of work, including 9,600 in Germany. It

5929-644: Was tested on the British Challenger 2 as a potential replacement for its rifled L30 120 mm cannon. A variety of ammunition has been developed for use by tanks with guns based on Rheinmetall's original L/44 design. This includes a series of kinetic energy penetrators , such as the American M829 series, and high-explosive anti-tank warheads. Recent ammunition includes a range of anti-personnel rounds and demolition munitions. The LAHAT , developed in Israel,
