The Abrams tank closes with and destroys enemy forces on the integrated battlefield using mobility, firepower and shock effect. 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 turbine engine, the 120 mm main gun and special armor make the Abrams tank particularly lethal against heavy armor forces.
M1A1 SA: Improvements include the Gunner’s Primary Sight with enhanced thermal imaging capabilities of the new Block I 2nd generation forward-looking infrared (FLIR) technology. Lethality improvements include the Stabilized Commander’s Weapon Station and ballistic solution upgrades for the M829A3 kinetic and the M1028 canister rounds. Modifications include Blue Force Tracking, a digital command and control system that gives commanders current information about their location relative to friendly forces, and the Power Train Improvement and Integration Optimization Program (Total InteGrated Engine Revitalization engine and improved transmission), which provides more reliability and durability. Survivability improvements include frontal armor and turret side-armor upgrades.
M1A2 SEPv2: Upgrades include improved survivability, automotive power pack, computer systems and night vision capabilities. Lethality improvements include Common Remotely Operated Weapon Station and ballistic solution upgrades for the M829A3 kinetic and the M1028 canister rounds. The M1A2 SEPv2 has improved microprocessors, color flat-panel displays, improved memory capacity, better Soldier-machine interface and a new open operating system designed to run the Common Operating Environment software. Both the Gunner’s Primary Sight and the Commander’s Independent Thermal Viewer tank include the improved thermal imaging capabilities of the new Block I 2nd generation FLIR technology.
M1A2 SEPv3: Improvements focus on increasing the electrical power margin; improving survivability with improved armor protection and advanced counter-improvised explosive device protection; integrating the new Army network; electronic component improvements; a new auxiliary power unit; and an ammunition data link.
