in the 1960s and reaching the testing stage by 1968. The MBT-70 was very ambitious, and had various innovative ideas that ultimately proved unsuccessful. As a result of the imminent failure of this project, the U.S. Army introduced the ''XM803''. This succeeded only in producing an expensive system with capabilities similar to the M60. Congress canceled the MBT-70 in November and XM803 December 1971. The Army restarted its M60 successor program with Major General

leading the team formulating requirements in March 1972. 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. A Pentagon task force submitted requirements for the tank in January 1973. By April the Pentagon approved the project with Brigadier General Robert. J. Baer as production manager. Desobry told ''The New York Times'', "We ought to be shot if it doesn't work." 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. Plans called for a tank weighing about 54 tons. By 1973 the Army had settled on buying 3,312 of the new tanks, with production beginning in 1980. The price of the $3 billion program was assailed by Congressman
Les Aspin Leslie Aspin Jr. (July 21, 1938 – May 21, 1995) was an American Democratic Party politician who served as the U.S. representative for Wisconsin's 1st congressional district from 1971 to 1993 and as the 18th United States Secretary of Defens ...
in July. The Pentagon had projected unit costs were to be less than US$507,000 in 1972 dollars. 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). 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." In June the Army awarded competitive three-year contracts - $68 million for

However the two nations were unable to reconcile their nationalistic differences, so a compromise was made that would have both tanks share common parts. 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. In November the Army selected Chrysler's design. Chrysler's proposal may have been attractive because the company said it could incorporate the Rheinmetall M256 120 mm

This range was crucial in combat against tanks of Soviet design in Desert Storm, as the effective range of the main gun in the Soviet/Iraqi tanks was less than .

. Although the RPG-7 is unable to penetrate the front and sides, the rear and top are vulnerable to this weapon. Frequently the rockets were fired at the tank tracks. An Abrams was disabled near Karbala after an RPG warhead penetrated the rear engine compartment. There were two reported losses during the Battle of Baghdad, with one Abrams being put out of action after being struck by numerous medium caliber weapons, including 12.7mm rounds which ruptured a fuel bladder stored on an external rack. This started a fire that spread to the engine. On April 4, two Abrams were destroyed by anti-aircraft guns, while on April 5, another was hit by a recoilless rifle and set aflame. After repeated attempts to extinguish the fire, the decision was made to destroy or remove any sensitive equipment. Oil and .50 caliber rounds were scattered in the interior, the ammunition doors were opened and several thermite grenades ignited inside. Another M1 then fired a HEAT round in order to ensure the destruction of the disabled tank. The Abrams was completely disabled but still intact. Later, the Air Force bombed the tank to destroy it in place, and the Iraqi Information Ministry claimed credit for destroying it.

It was reported that 28 Iraqi Army Abrams had been damaged in fighting with militants, five of them suffering full armor penetration when hit by ATGMs, in the period between 1 January and the end of May 2014; some were destroyed or damaged by militants placing explosive charges on or in the vehicles, highlighting the lack of adequate infantry support provided by Iraqi soldiers.

The lone working Abrams performed exceptionally in combat, destroying enemy IEDs, punching holes in defenses, and maneuvering between multiple engagements. U.S. forces monitoring Iraqi movements thought multiple tanks were in operation and were surprised to learn it had been working alone, crediting its success to the U.S.-trained crew. The Abrams was nicknamed "The Beast" and has achieved somewhat of a folklore status among the Iraqi people.

. While the exact number of losses is not clear due to poor reporting from the conflict, it became clear that a certain number of Saudi tanks were lost to enemy forces using ATGMs, RPGs and mines. During summer 2016, a deal to sell 153 more M1 tanks to Saudi Arabia was revealed, with 20 of them being tagged as "battle damage replacements", implying that a similar number of Saudi M1 tanks were lost to the enemy.


Afghanistan

Operating tanks in Afghanistan can be difficult due to the terrain, although Canada and Denmark have deployed tanks to Afghanistan that have been specifically upgraded to fight in the tough Afghan environment. The U.S. sent 16 M1A1 Abrams tanks and 115 Marines to southern Afghanistan to support operations in the Helmand and Kandahar provinces in late 2010.

was to replace the Abrams in U.S. service and was in late stages of development when funding for the program was cut from the DoD's budget. In September 2009, the ''Army Times'' and ''Marine Corps Times'' published reports that US Army researchers have begun the process of designing a version of the Abrams that will carry the M1A3 label. According to the reports, the Army is seeking to reduce the weight of the vehicle to approximately 60 tons from its current operational weight of roughly 75 tons. Additionally, the M1A3 may incorporate a new generation of advanced networking capabilities and enhanced armor protection. Other improvements are to include a lighter 120 mm gun, added road wheels with improved suspension, a more durable track, lighter armor, long-range precision armaments, and

and laser detectors. A new internal computer system is also planned, with current cabling replaced by fiber-optic cables that can reduce weight by two tons. The Army currently aimed to build prototypes by 2014 and to begin to field the first combat-ready M1A3s by 2017, however due to financial shortcomings and delays, there has yet to be a single tank produced (To the public's knowledge.)


Production

The military planned to close the M1 Abrams factory in
Ohio Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The sta ...
from 2013 to 2016 to save over US$1 billion. In 2017 the plant would reopen to upgrade existing tanks. The downside to the three-year plant closing is the loss of the skilled human capital required to build the M1. These types of job skills must be learned on the job as the building is too unique to offer any type of educational program in a trade school environment. By August 2013, Congress had allocated $181 million for buying parts and upgrading Abrams systems to mitigate industrial base risks and sustain development and production capability. Congress and General Dynamics were criticized for redirecting money to keep production lines open and accused of "forcing the Army to buy tanks it didn't need." General Dynamics asserted that a four-year shutdown would cost $1.1–1.6 billion to reopen the line, depending on the length of the shutdown, whether machinery would be kept operating, and whether the plant's components would be completely removed. They contended that the move was to upgrade Army National Guard units to expand a "pure fleet" and maintain production of identified "irreplaceable" subcomponents; a prolonged shutdown could cause their makers to lose their ability to produce them and foreign tank sales were not guaranteed to keep production lines open. Even though money is being spent to protect the industrial base, some feel those strategic choices should not be made by members of Congress, especially those with the facilities in their district. There is still risk of production gaps even with production extended through 2015; with funds awarded before recapitalization is needed, budgetary pressures may push planned new upgrades for the Abrams from 2017 to 2019. In December 2014, Congress again allocated $120 million, against the wishes of the Army, for Abrams upgrades including improving gas mileage by integrating an auxiliary power unit to decrease idle time fuel consumption and upgrading the tank's sights and sensors. At the end of 2016, tank production/refurbishment had fallen to a rate of one per month, with less than 100 workers on site. However, the Trump administration entered office in 2017 and made rebuilding the military a priority, thus the Lima Army Tank Plant was given a new lease on life. It was reported in 2018 that the Army had ordered 135 tanks re-built to new standards, employment was over 500 workers and expected to rise to 1,000.
