Severe Duty (SD)


BAE Systems introduces a proven, superior chassis built for mobility in rugged and extreme operating conditions, as well as best-in-class durability.


Our chassis system is based on the FMTV, a family of tactical vehicles designed and manufactured by BAE Systems for the U.S. Army. With over 60,000 vehicles in active duty all over the world, the FMTV established new standards for mobility, reliability and capability in the Army’s tactical vehicle fleet. Leveraging our successful military legacy, BAE Systems introduces a superior chassis to the severe/extreme duty global market. Now available on commercial 4x4 and 6x6 platforms, we’ve brought military toughness to civilian duty.


Unmatched in durability and mobility in extreme operating environments, BAE Systems Extreme Duty Chassis provides a solid investment, exceptional capabilities and superior performance. The Chassis offers clear value and return on investment, over the life of the vehicle.

Our flexible frame design adapts to severe terrain—avoiding those maintenance and repair issues when on-road vehicles are driven off-road. The Chassis has demonstrated its reliability in military vehicles by operating at greater than 95% availability rate, with over 400 million miles driven, averaging 15 years of service.

The Extreme Duty Chassis has superior ground clearance and slope-climbing capabilities, can ford though 30 inches of water and offers a Central Tire Inflation System (CTIS). Driving where other vehicles can’t provides major savings in stuck vehicle retrieval costs, vehicle down time, additional transport and labor inefficiencies.

After five years of use in an extreme operating environment, an on-road vehicle may no longer be on the road. But our Extreme Duty Chassis is designed to last 20 years in an off-road/extreme environment— outlasting any other comparable vehicle and reducing lifecycle costs.

With spares and services available around the globe, the Chassis integrates components from global brands including CAT®, Cummins®, Allison® and Meritor®.


Platforms & Services has key positions in the land and maritime sectors, designing, developing, producing and supporting platforms, naval weaponry and munitions, as well as protective wear and armor. P&S operates in the US, the UK, South Africa, and Sweden with markets in more than 40 countries.
