 As the process is completed at the speed of electricity the plates are moving when struck by the projectile causing the projectile energy to be deflected whilst the energy is also dissipated in parting the magnetically attracted plates.Some active protection systems, like the German AMAP-ADS or the American Iron Curtain, have explosive modules that destroy projectiles with a directed energy explosion.This type of explosive module is similar in concept to the classic ERA, but without the metal plates and with directed energy explosives.
