The M1A3 Abrams is an upgraded version of the M1A2 Abrams. The M1A3 is an American Main Battle Tank, designed to replace the then aging M60 Patton.
The first attempt to replace the aging M60 tank was the MBT-70, developed in partnership with West Germany in the 1960s. The MBT-70 had advanced features such as a height-adjustable air suspension and a very small body with the driver in a turret design that allowed the driver to always face the direction of travel. The MBT-70 ultimately proved to be too heavy, complex, and expensive, thus she was cancelled in 1971.

The M1A3 was operated by the US Army up until 2030, when it was put into reserve (namely for use by the National Guard). The M1A3 was soon after replaced by the M15 Eisenhower, which outmatched the Russian T-105 Koloss and T-14 Armata. It was (almost) a match to the Daitai-built Type-98 Bishamonten Main Battle Tank.
