The M1A2 SEP V3 is the latest generation of American main battle tank in the M1 Abrams family. he M1A2 Abrams SEP V3 (System Enhanced Package) is a modernized version of the M1A2 SEPV V2 main battle tank which has a number of upgrades in the areas of survivability, maintainability, full efficiency and network capability. In October 2015, the M1A2 SP V3 was presented for the first time at AUSA, defense exhibition in Washington D.C. Nine prototype are available since October 2015 and seven would be tested by the U.S. Army.

In September 2017, the website SCOUT has announced that U.S. Army will receive first of six newly-upgraded M1A2 SEP v3 Abrams Main Battle Tank.

The new M1 Abrams MBT variant also includes improved connectivity—allowing for better communications with advanced network capabilities. Tank crews are also afforded vastly improved displays and man-machine interfaces that should enhance their situational awareness.

The M1A2 SEP V3 also has improved survivability and lethality compared to older Abrams models. The new Abrams tank has advanced abilities to defeat improvised explosive devices and has an upgraded armor package. The addition of a new Ammunition Data Link supports use of advanced new ammunition types that are either already fielded or will be fielded in the near future.
