L-3 ES is leading the development of an electronic suspension system for ground vehicles called, ECASS that will greatly enhance the mobility and mission effectiveness of military vehicles.

ECASS improves the off-road mobility and maneuverability of both wheeled and tracked vehicles. This substantially increases ground force mission success rates by providing stable mobile platforms for firing weapons. It also enables troops and vital supplies to be transported faster and safer to where they are needed, arriving combat ready.


Mobility and maneuverability - Two-to-threefold increase in speed over off-road terrain quickens the tempo of battle for combat forces.
Enhanced survivability and mission effectiveness - Improved vehicle handling and stability enables more accurate C4ISR and weapon delivery, and active recoil management, which minimizes time between weapon firings.
Crew effectiveness - Crewmembers experience six-to-eight times less vibration and shock, thereby reducing soldier stress and fatigue and maintaining soldier efficiency for longer periods of time.
Vehicle safety - ECASS can reduce Centre of Gravity height during severe cornering maneuvers to reduce vehicle roll over susceptibility.
Reliability/cost savings - ECASS’ ability to minimize absorbed energy from terrain-induced shock and vibration can significantly reduce motion related vehicle and electronics failure rates, protect shock/vibration sensitive munitions and potentially reduce overall life cycle costs. Additionally, increased payload flexibility without significant degradation in suspension performance can provide opportunities for reducing transportation costs and expanding mission capability.
Fuel economy - The ability of ECASS to store and regenerate damping energy reduces vehicle off-road rolling resistance and fuel consumption compared to vehicles with conventional suspension systems.
