Raytheon, with the US Army, has completed a successful preliminary design review (PDR) of the DeepStrike surface-to-surface missile, the company announced on 26 March.
The successful PDR paves way for flight tests later in 2019.
The DeepStrike missile meets the army's requirement for a new precision strike missile. Featuring two-in-the-pod design, the missile will be capable of defeating fixed land targets 60-499km away.
During the PDR, the army evaluated all aspects of the new missile's design, including its advanced propulsion system, lethality package and guidance system.
Previous programme milestones include the successful integration of DeepStrike's new launch pod missile container into the army's M142 HIMARS and M270 MLRS launchers.
