"This is the last qualification test in a series of five qualification tests," Michael Bright, vice president of the Missile Defense and Strategic Systems Business Unit. "It is the final ground test verification needed to support SM-3 Block IB production decisions this year."

The SM-3 is powered by Aerojet's MK 72 first stage booster and MK 104 second stage dual-thrust rocket motor. The SM-3 is part of the Missile Defense Agency's Aegis Ballistic Missile Defense System Phased Adaptive Approach, which uses kinetic technology for the destruction of in-coming missiles.
