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 ).
It is the main powerplant of the M1 Abrams series of tanks. The engine was originally designed and produced by the Lycoming Turbine Engine Division in the Stratford Army Engine Plant. In 1995, production was moved to the Anniston Army Depot in Anniston, Alabama, after the Stratford Army Engine Plant was shut down. [1]
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.

In February 1980, the first M1 Abrams rolled out of LATP. After a contract the plant began producing the Abrams at a rate of 30 a month. Chrysler subsequently sold the Defense subsidiary to General Dynamics in 1982. [3] In January 1985, the last M1 rolled off the assembly line, and in October, production began on the improved M1 (IPM1).
Mounted Warfare TestBed (MWTB) at Fort Knox, Kentucky, was the premier site for distributed simulation experiments in the US Army for over 20 years. It used simulation systems, including fully manned virtual simulators and computer-generated forces, to perform experiments that examined current and future weapon systems, concepts, and tactics.
Systems that the ASM sought to replace included the M1 Abrams main battle tank, M109 howitzer and M2 Bradley infantry fighting vehicle. The Army spun out several of the systems— Advanced Field Artillery System , Line-of-Sight Anti-Tank and the Armored Gun System —after canceling the program, but all of these programs were eventually canceled.
This variant is unofficially referred to by Abrams tank crews as the "super sabot". [4] Although the M829A3 fired from the 44-caliber M256 gun has a lower muzzle velocity than 120 mm shells fired from the Rheinmetall 55-caliber gun barrel or Russian 2A46 125 mm gun ammunition, it uses a larger penetrator with increased mass to increase imparted ...
