The M1A2 tank has a 120-millimeter main gun, weighs 63 tons, can travel at a top speed of 42 miles per hour, and has a crew of four.
The M1A2 System Enhancement Package version 1 (SEP V1) improvements -- which also are part of the SEP V2 tanks -- included digital control, second-generation thermal imaging systems for the commander's independent viewer (CITV) and gunner, and a gun sight that uses 2nd generation forward-looking infrared (FLIR) sensors.
The main gun is stabilized to enable accurate fire on the move capability in day or night. The driver has a wide-field-of-view thermal driver vision enhancer (DVE) for driving and situational awareness.
The tank vetronics systems in the SEP V1 tanks include enhanced GPS and inertial position/navigation system, color, digital terrain map display, and eye-safe laser rangefinder. Radios include SINCGARS and Enhanced Position/Location Reporting System (EPLRS) supporting tactical situational awareness.
On-board systems connected on a MIL-STD-1553 digital databus, and include an on-board malfunction detection system. The SEP V1 tanks also have monolithic and composite armor and compartmented storage for fuel and ammunition. The turbine engine was upgraded to a multi-fuel system.
On the latest SEP V2 tank contract, General Dynamics will do the work in Lima, Ohio; Tallahassee, Fla.; Anniston, Ala.; Scranton, Pa.; and Sterling Heights, Mich., and should be finished by June 2013. Awarding the contract were officials of the Army TACOM Life Cycle Management Command in Warren, Mich.
