U.S. Army Testing M1A2 SEPv3 Main Battle Tank at Yuma Proving Ground (YPG)

The U.S. Army is currently testing its newest M1A2 SEPv3 (Systems Engineering Plan Version 3) Main Battle Tank at the Yuma Proving Ground (YPG).

M1A2 SEPv3 is the latest version of the M1 Abrams main battle tank (MBT) operated by the U.S. Army and allies. The tank is now being put through its paces across the more than 200 miles of rugged road courses at the Yuma Proving Ground.

The SEPv3 will replace the M1A2 SEPv2 which has been in production since 2005, and has extensive improvements compared to the earlier versions.

Production for the M1A2 SEPv3 is being conducted at Joint Systems Manufacturing Center (JSMC) in Lima, Ohio and at the Anniston Army Depot in Anniston, Alabama. The first of six M1A2 SEPv3 initial production vehicles was accepted by the U.S. Army on Oct. 4 last year.

The M1A2 SEPv3 improvements include:

+ Joint Tactical Radio System (JTRS): Integration of the Government Furnished Equipment Joint Tactical Radio System Handheld, Manpack, and Small Form Fit radio to support the need to establish network readiness and maintain battle command and communications interoperability with future Brigade Combat Teams.

+ Power Generation and Distribution: Aspects include Improved Amperage Alternator, Slip Ring, Enhanced Hull Power Distribution Unit/Common Remote Switching Modules, and the Battery Monitoring System. These technologies address the power demand growth potential and the need for dissemination of critical information.

+ Line Replaceable Unit (LRU)/Line Replaceable Modules (LRM) Redesign: Migration of current force Abrams platforms to a two-level maintenance scheme can be initiated through the implementation of Line Replaceable Module technology.

+ AN/VLQ-12 Counter RCIED (Remote Controlled Improvised Explosive Device) Electronic Warfare (CREW) Duke V3: It is a vehicle-mounted, lightweight system that neutralizes RCIED threats and gives U.S. troops a tactical advantage across the full spectrum of operations. CREW/Duke V3 is the latest version from PM CREW.

+ Ammunition Data Link (ADL): The ADL is required to program the M829A4 Advanced Kinetic Energy and Advanced Multi-Purpose rounds.

+ Auxiliary Power Unit (APU): The under armor APU provides capability to operate on-board systems with a reduced probability of detection during silent watch operations.

+ Armor Upgrades: The Abrams Tank will continue to advance its ballistic protection to counter the latest threats and maintain battlefield superiority.
