The Ultimate Question: Could America Stop a Nuclear Attack from North Korea?

New technology could help. 

If the seeker or guidance systems of a “kill vehicle” technology on a GBI cannot discern an actual nuclear-armed ICBM from a decoy – the dangerous missile is more likely to pass through and avoid being destroyed.  MOKV is being developed to address this threat scenario.

The Missile Defense Agency has awarded MOKV development deals to Boeing, Lockheed and Raytheon as part of a risk-reduction phase able to move the technology forward, MDA officials said.

Steve Nicholls, Director of Advanced Air & Missile Defense Systems for Raytheon, told Scout Warrior last year that the MOKV is being developed to provide the MDA with “a key capability for its Ballistic Missile Defense System. The idea is to discriminate lethal objects from countermeasures and debris. The kill vehicle, launched from the ground-based interceptor extends the ground-based discrimination capability with onboard sensors and processing to ensure the real threat is eliminated.”

MOKV could well be described as a new technological step in the ongoing maturation of what was originally conceived of in the Reagan era as “Star Wars” – the idea of using an interceptor missile to knock out or destroy an incoming enemy nuclear missile in space. This concept was originally greeted with skepticism and hesitation as something that was not technologically feasible.

Not only has this technology come to fruition in many respects, but the capability continues to evolve with systems like MOKV. MOKV, to begin formal product development by 2022, is being engineered with a host of innovations to include new sensors, signal processors, communications technologies and robotic manufacturing automation for high-rate tactical weapons systems, Nicholls explained.

The trajectory of an enemy ICBM includes an initial “boost” phase where it launches from the surface up into space, a “midcourse” phase where it travels in space above the earth’s atmosphere and a “terminal” phase wherein it re-enters the earth’s atmosphere and descends to its target. MOKV is engineered to destroy threats in the “midcourse” phase while the missile is traveling through space.

An ability to destroy decoys as well as actual ICBMs is increasingly vital in today’s fast-changing technological landscape because potential adversaries continue to develop more sophisticated missiles, countermeasures and decoy systems designed to make it much harder for interceptor missile to distinguish a decoy from an actual missile.

As a result, a single intercept able to destroy multiple targets massively increases the likelihood that the incoming ICBM threat will actually be destroyed more quickly without needing to fire another Ground Based Interceptor.  

Raytheon describes is developmental approach as one that hinges upon what’s called “open-architecture,” a strategy designed to engineer systems with the ability to easily embrace and integrate new technologies as they emerge.  This strategy will allow the MOKV platform to better adjust to fast-changing threats, Nicholls said.

The MDA development plan includes the current concept definition phase, followed by risk reduction and proof of concept phases leading to a full development program, notionally beginning in fiscal year 2022, Raytheon officials explained.

MDA officials have told Scout Warrior that the MOKV program shows great promise for the future of missile defense technology.

While the initial development of MOKV is aimed at configuring the “kill vehicle” for a GBI, there is early thinking about integrating the technology onto a Standard Missile-3, or SM-3, an interceptor missile also able to knock incoming ICBMs out of space. The SM-3 is also an exo-atmopheric "kill vehicle," meaning it can destroy short and intermediate range incoming targets; its "kill vehilce" has no explosives but rather uses kinetic energy to collide with and obliterate its target. The resulting impact is the equivalent to a 10-ton truck traveling at 600 mph, Raytheon statements said.
