Provides mobility, firepower, and shock effect with lethality, survivability, and fightability necessary to close with and destroy enemy forces on the integrated battlefield.
The Abrams Tank Upgrade includes two powerful variants, the M1A1 SA (Situational Awareness) and the M1A2 SEP (System Enhancement Program) Version 2. The 1,500-horsepower AGT turbine engine, the 120mm main gun, and special armor make the Abrams tank particularly lethal against heavy armor forces. Both variants feature the new Block I 2nd generation forward-looking infrared (FLIR) technology and ballistic solution upgrades for the M829A3 kinetic and the M1028 canister rounds.
M1A1 SA: Improvements include the Gunner’s Primary Sight (GPS), with the new Block I 2nd generation FLIR technology and the Stabilized Commander’s Weapon Station (SCWS). Modifications include Blue Force Tracking (BFT), a digital command and control system that gives commanders information about their location relative to friendly forces; and the Power Train Improvement and Integration Optimization Program (Total InteGrated Engine Revitalization (TIGER) engine and improved transmission), which provides more reliability and durability. Survivability improvements include frontal armor and turret side armor upgrades.
M1A2 SEP v2: Lethality improvements include the Common Remotely Operated Weapon Station (CROWS). The M1A2 SEP v2 has enhanced microprocessors, color flat-panel displays, better Soldier-machine interface, and a new open operating system designed to run the Common Operating Environment (COE) software. Both the GPS and the Commander’s Independent Thermal Viewer (CITV) tank include Block I FLIR technology. The M1A2 SEP has improved frontal and side armor for enhanced crew survivability. The vehicle is also equipped with battery-based auxiliary power, TIGER, and an upgraded transmission for improved automotive reliability and durability.
