Electrified Transmission for US Army Armored Combat Vehicles

The US Army has awarded Allison Transmission a $6.55 million contract to design, develop and test an electric hybrid sub-system in Allison’s Next Generation Electrified Transmission for armored combat vehicles.

The Next Generation Electrified Transmission is the newest product in Allison’s tactical ground combat vehicle portfolio. It features a 220 kilowatt electric motor and associated inverter for on-board vehicle power and parallel electric hybrid operation. 

Beyond power generation for auxiliary system capability development, the propulsion solution provides benefits realized in enhanced mobility performance and efficiency with a significant reduction in fuel consumption and reduced thermal and acoustic signatures.

“The Next Generation Electrified Transmission will provide far more than power generation. Our technology will deliver electric hybrid propulsion using blended torque that provides edge-of-the box performance or true engine-off silent mobility,” said Dana Pittard, Vice President Defense Programs at Allison Transmission. “Allison has two decades of expertise with electric hybrid propulsion technology. We’re committed to continuing to lead the way in developing innovative technology that will help the US military to successfully accomplish the mission.”

With the Next Generation Electrified Transmission, Allison anticipates meeting requirements across a wide spectrum of applications, including the US Army’s Optionally Manned Fighting Vehicle (OMFV) and Main Battle Tank markets in the United States and around the world. 

The OMFV program will replace nearly 3,000 aging legacy Bradley vehicles, which will be the Army’s largest armored vehicle procurement since the 1980s.

Specifically, the Next Generation Electrified Transmission has been selected by American Rheinmetall Vehicles (ARV) for integration into its OMFV offering. The ARV vehicle delivers high mobility and unmatched power in a maneuverable and modern chassis designed to meet the US Army’s combat vehicle modernization priorities.

“Since 1946, Allison has partnered with the Department of Defense to develop propulsion solutions that deliver in the toughest conditions. For fleets that are developing new wheeled or tracked vehicles, Allison can tailor a transmission, electric hybrid or electric propulsion solution specifically for that application,” said Pittard. “Allison engineers and manufactures reliable and fully customizable propulsion solutions, so customers experience reduced downtime and increased ability to accomplish mission objectives.”
