The US Army’s M1A2 Abrams main battle tanks (MBTs) are receiving a Collins Aerospace-provided upgrade that will deliver a significant uplift to their onboard power and thus their survivability and reliability, the RTX business announced on 15 August 2023.

Under a USD 24 M (EUR 22 M) contract Collins Aerospace is producing and delivering electric generators with containers as part of the army’s System Enhanced Package version 3 (SEPv3) to improve the M1A2’s performance and extend its service life.

The new generators, which are being delivered to the US Army’s Anniston Depot, deliver 50% more onboard power than the vehicle’s legacy system, according to a company press release. The new generators also fit in the same space as the legacy system without requiring major changes to the vehicle or its existing electric systems architecture.

“Across our business we are leveraging electric power, from commercial aerospace to military platforms, to support the evolving needs of our customers,” Russell Andrey, programme manager for Collins Aerospace, was quoted as saying in a company press release. “To date Collins has delivered 800 electric generators in support of the SEPv3 program, supplying critical power, diagnostics and predictive maintenance support on the ground.”

With its increased power, the electric generator helps improve the M1A2’s survivability by enabling the addition of advanced systems, such as laser warning receivers and radio jamming capabilities. The company’s generator uses advanced magnetics and active load management to deliver 100% rated power throughout the M1A2’s operating range. In addition, the state-of-the-art system boasts enhanced digital capabilities through its advanced generator control and communications features.
