US Army accepts first M1A2 SEPv3 version of Abrams main battle tank


The US Army has accepted the first of six M1A2 system enhancement package version 3 (SEPv3) of Abrams main battle tanks (MBTs).

Initial production of the M1A2 SEPv3 vehicles is carried out at Joint Systems Manufacturing Center in Lima, Ohio and at the Anniston Army Depot in Anniston, Alabama.

US Army Abrams product manager lieutenant colonel Justin Shell said: "This version is the most modernised configuration of the Abrams tank, having improved force protection and system survivability enhancements and increased lethality over the M1A1 and previous M1A2 variants.

"The Abrams M1A2 SEPv3 tank will be the foundation for future incremental system upgrades and can host any mature technology the army deems operationally relevant."

The M1A2 SEPv3 vehicles have been integrated with joint tactical radio system handheld, manpack, and small-form fit radio for battle command and communications interoperability.

"The Abrams M1A2 SEPv3 tank will be the foundation for future incremental system upgrades and can host any mature technology the army deems operationally relevant."

The other improvements delivered include armour upgrades, redesign of line replaceable unit / line replaceable modules and installation of an ammunition data link to programme the M829A4 advanced kinetic energy and advanced multi-purpose rounds.

Furthermore, the new version MBT has been fitted with an under armour auxiliary power unit to operate on-board systems during silent watch operations and counter remote control improvised explosive device electronic warfare V3.

The M1A2 SEPv3 also received improved amperage alternator, slip ring, enhanced hull power distribution unit / common remote switching modules and the battery monitoring system to address the power demand growth potential.

The Abrams M1A2 SEPv3 tank will replace the M1A2 SEPv2, which has been in production since 2005.
