On November 19, the U.S. Missile Defense Agency chose Lockheed Martin, Northrop Grumman, and Raytheon Missiles and Defense to complete an “accelerated concept design” of the Glide Phase Interceptor (GPI). The GPI is MDA’s primary hypersonic defense program and is designed to intercept hypersonic weapons kinetically in the endoatmospheric glide phase. GPIs will equip U.S. Aegis ships using their VLS 41 containers.
