The modern core of President Ronald Reagan’s Strategic Defense Initiative is called Ground-based Midcourse Defense technology (GMD). That technology can engage and destroy intermediate and long-range ballistic missiles in space to protect America’s homeland.
It relies on ground-based interceptor (GBI) rockets to deploy exoatmospheric kill vehicles (EKV) into the path of incoming nuclear warheads. Those EKVs use globally deployed sensors and sensor/propulsion technology onboard to guide the vehicle to use kinetic energy from a direct hit to destroy the incoming target vehicle. That has been proven to work to stop incoming missiles in recent tests.
The Pentagon was planning to modernize this system by replacing the old EKVs with new redesigned kill vehicles (RKVs), specifically intended to defend against possible ballistic missile attacks from North Korea and Iran. But in May this year, the Pentagon reported a two-year delay in the RKV’s development and announced a pause in the modernization as a result.
Now Michael Griffin, undersecretary of Defense for research and engineering, has issued a stop-work order to Boeing on further development of the new, more modern RKV “due to technical design problems.” Raytheon is the actual developer of the RKV, serving as a subcontractor to Boeing.
The RKV was meant to replace the EKVs on all current and future GMD interceptor rockets, a total of 64 ultimately. Currently, there are 44 GBIs at Fort Greely in Alaska and Vandenberg Air Force Base in California, with plans to add 22 additional missile silos at Fort Greely to support 20 more GBIs.
Under the new Defense Department budget, the RKV is now planned for its first intercept test in fiscal 2023. The plan is now to deploy the RKV on GBI missiles in 2025 at the soonest.
Meanwhile, the old EKV is still working, now better than ever, given the most recent tests. The Missile Defense Agency needs to complete its modernization with the new RKV before missile defense is dangerously degraded.
