United Defense has released that the hybrid-electric drive combat vehicle outfitted with an Electro-Magnetic Armor (EMA) package has successfully defeated incoming threats during a live-fire testing. The tests were conducted Feb 22 at Aberdeen Proving Ground in Maryland.

The EMA-equipped combat vehicle demonstrator was accomplished through a cooperative research and development agreement with the U.S. Army Research Laboratory and the Army's Tank Automotive Research Development and Engineering Center (TARDEC) in Warren, Michigan. This approach will facilitate integration of life-saving advanced technology much more rapidly than through traditional methods. The threats employed during the live fire tests were shaped charge warheads.

EMA provides the same or similar level of protection than Explosive Reactive Armor (ERA) packages through an integrated package with lower weight on an hybrid-electric drive vehicle. EMA is being developed as part of a layered approach aimed at increasing US Army units protection. This approach is a key component of Future Combat Systems (FCS) platforms protection which will be based on both active and passive defense mechanisms in addition to hard-skin/armor.

EMA uses high voltages and high currents to defeat shaped charge warheads such as those from Rocket Propelled Grenades (RPGs). The electrical power generated through these high voltages and currents melts the shaped charge warhead metal diminishing or evaporating the solid-state metal and its penetration capability. Power management is the key for Pulse Forming Networks (PFN) which is the basis for EMA on a combat vehicle.
