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.
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 ...
The M1150 Assault Breacher Vehicle (ABV) is a U.S. military mine- and explosives-clearing vehicle, based on the M1 Abrams chassis, equipped with a mine plow and line charges. Its first large scale use by the US Marines (USMC) was in the joint ISAF -Afghan Operation Moshtarak in Southern Afghanistan during the War in Afghanistan in 2010 against ...
The M1A1/M1A2 tank can carry only 40 rounds for its 120 mm M256 gun—the M60A3 Patton tank (the Abrams' predecessor), carried 63 rounds for its 105 millimetres (4.1 in) M68 gun. This effect is reduced by the higher first round hit rate of the Abrams with its improved fire control system compared to that of the M60.
The U.S. Army's M1 Abrams MBT with TUSK (Tank Urban Survival Kit) upgrade uses composite, reactive and slat armour. Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire.
The M1074 Joint Assault Bridge System (JAB, JABS) is an American armored military engineering vehicle based on the Abrams M1A1 main battle tank chassis. [8]: p.154 The M1074 was designed by Leonardo DRS for the U.S. Army and Marine Corps to provide deployable bridge capability for units engaged in military operations.
