Raytheon Missiles & Defense, a Raytheon Technologies business, has completed the systems requirements review – prototype (SRR-P) for the Glide Phase Interceptor (GPI), marking an important milestone in the US hypersonic missile defence program.
The milestone comes after the US Missile Defence Agency awarded a contract to Northrop Grumman and Raytheon Missiles and Defense to continue developing prototypes of a GPI.
