America’s M1 Abrams tanks come in a number of versions. In addition to the M1A1 that is now standard, the US Army is beginning to field its M1 TUSK for urban warfare. It also operates the M1A2 System Enhancement Program (SEP), currently the most advanced standard variant.
The M1A2 SEP is builds on the digitized M1A2 platform with an improved armor package of third generation steel-encased depleted uranium armor, a new command and control system, second-generation FLIR thermal sights that include a Commander’s Independent Thermal Viewer (CITV) for “hunter-killer” operation, the Under Armor Auxiliary Power Unit (UAAPU) that lets crews run key electronics without running the engine, and a Thermal Management System (TMS – i.e. air conditioning for crew & electronics). The M1A2 SEP also features enhanced electronics like color maps and displays, improved networked communications, high-density computer memory and increased microprocessing speed, a more user friendly “Soldier Machine Interface (SMI)”, and an open operating computing system that will make future upgrades and additions easier.

The most recent addition is a $600+ million contract to begin the final set of SEP upgrades for the active-duty army…
