The M1IP models were used in the Canadian Army Trophy NATO tank gunnery competition in 19.Ībout 6,000 M1A1 Abrams were produced from 1986–92 and featured the M256 120 mm smoothbore cannon developed by Rheinmetall AG of Germany for the Leopard 2, improved armor, and a CBRN protection system. An improved model called the M1IP was produced briefly in 1984 and contained small upgrades. It was armed with the license-built version of the 105 mm Royal Ordnance L7 gun. In 1979, General Dynamics Land Systems Division purchased Chrysler Defense.ģ,273 M1 Abrams were produced 1979-85 and first entered US Army service in 1980. Chrysler's proposal may have been attractive because the company said it could incorporate the Rheinmetall M256 120 mm cannon without increasing costs, weight or the production timeline. In November the Army selected Chrysler's design. In July the Army recommended selecting the General Motors offering, but the recommendation was disregarded by the Pentagon, which asked competitors to modify their proposals to share parts with the German tank. However the two nations were unable to reconcile their nationalistic differences, so a compromise was made that would have both tanks share common parts. The Pentagon in 1994 also allowed the West German Leopard 2 to be tested against the American winner at Aberdeen with the understanding that the better tank would be adopted by both countries. They were armed with the license-built version of the 105 mm Royal Ordnance L7 gun. Chrysler chose a regenerative turbine engine made by Avco Lycoming while General Motors chose a Teledyne Continental diesel engine. In February 1976 the two prototypes were tested at Aberdeen Proving Ground. In June the Army awarded competitive three-year contracts – $68 million for Chrysler Corporation and $87 million to General Motors Corporation – for the production of prototypes. ![]() Noting that the M60 Patton cost only $500,000 each, Aspin said, "I'm sure that the Army's new tank is not twice as good as what we have today." Aspin argued that were the research and development costs factored in, tanks would actually cost over $900,000 a piece (compared to $1.3 million for the canceled MBT-70). The Pentagon had projected unit costs were to be less than US$507,000 in 1972 dollars. The price of the $3 billion program was assailed by Congressman Les Aspin in July. By 1973 the Army had settled on buying 3,312 of the new tanks, with production beginning in 1980. Plans called for a tank weighing about 54 tons. The Pentagon's requirements specified a tank gun between 105 and 120-mm and a Bushmaster cannon with a caliber between 20 and 30-mm. Desobry told The New York Times, "We ought to be shot if it doesn't work." By April the Pentagon approved the project with Brigadier General Robert. A Pentagon task force submitted requirements for the tank in January 1973. Army officials told congressmen in April that there was little that could be salvaged from the past efforts, and that a new tank would take at least eight years to develop. The Army restarted its M60 successor program with Major General William Robertson Desobry leading the team formulating requirements in March 1972. Ĭongress canceled the MBT-70 in November and XM803 December 1971. This succeeded only in producing an expensive system with capabilities similar to the M60. As a result of the imminent failure of this project, the U.S. The MBT-70 was very ambitious, and had various innovative ideas that ultimately proved unsuccessful. The first attempt to replace the M60 Patton was the MBT-70, developed in partnership with West Germany in the 1960s and reaching the testing stage by 1968. Since then, it has gone through dozens of upgrades and been the baseline variant of several vehicles.ĭevelopment An XM1 Abrams during a demonstration at Fort Knox, Kentucky, in 1979 The M1 Abrams main battle tank has been in service since 1980.
