The M1 Abrams (/ ˈ eɪ b r ə m z /) [10] is a third-generation American main battle tank designed by Chrysler Defense (now General Dynamics Land Systems) and named for General Creighton Abrams. Conceived for modern armored ground warfare , it is one of the heaviest tanks in service at nearly 73.6 short tons (66.8 metric tons ).
Despite all these advances, the Abrams still retained the 4-man crew of the M60 tank as the autoloader was considered unproven and risky. Over 3,200 M1 Abrams were produced and first entered US Army service in 1980. About 6,000 upgraded M1A1 Abrams were produced and used a 120 mm smoothbore cannon, improved armor, and a CBRN protection system.
The M1 can be equipped with mine plow and mine roller attachments if needed. The M1 chassis also serves as a basis for the Grizzly combat engineering vehicle and the M104 Wolverine heavy assault bridge. Over 8,800 M1 and M1A1 tanks have been produced at a cost of US$2.35–$4.30 million per unit, depending on the variant.
All Wisconsin's products were 4-cycle and they had power outputs from 2.4 to 65.9 horsepower (2 to 49 kW). There were single, inline two, V-two, and V-four cylinder models. The engines were designed for outdoor field service in industries including agriculture, construction, marine, oil-field equipment and railway maintenance. [ 6 ]

Although the L11/M256 120mm gun was chosen to be the main weapon of the Abrams in 1979, the improved ammunition for the gun still was not fully developed, thus delaying its fielding until 1984. [5] A license was obtained for its manufacture at Watervliet Arsenal at Watervliet, New York. [6]
