The first six initial production vehicles of the M1A2 Abrams Main Battle Tank System Enhancement Package Version 3 (SEPv3) has been rolled out for the first time after delivery to the US Army. Production for the M1A2 SEPv3 is being conducted at the Joint Systems Manufacturing Center (JSMC) in Lima, Ohio and at the Anniston Army Depot in Anniston, Alabama. Improvements added to the new tanks include a joint tactical radio system that integrates handheld, manpack, and small-form fit radios to maintain battle command and communications interoperability with future brigade combat teams. It also comes with an improved power generation and distribution equipment, as well as counter remote control improvised explosive device electronic warfare/Duke V3 equipment. An ammunition data link for programing the M829A4 advanced kinetic energy and advanced multi-purpose rounds has also been added, as well as a quiet auxiliary power unit to operate on-board systems during silent watch operations, and armor upgrades. Over time, the SEPv3s will replace the M1A2 SEPv2, which have been in production since 2005.
