US Army Held Missile Defense War Games to Subvert 'Russian Jamming'
by Staff Writers
Last spring, the US Army conducted a highly classified exercise deep in the New Mexico desert. Held at White Sands Missile Range, the electronic warfare drills were designed to find weaknesses in the Pentagon's missile defense capabilities.
To accomplish this, the military mimicked a series of offensive jamming attacks to test the readiness of the defense system. Evidently, those networks need a lot of improvement, as the results of the exercise produced nearly 70 terabytes of data, roughly twice the size of Wikipedia.
But the prime reason for the drills is concern that Russian and Chinese technology is too advanced for the US military to confront. According to Brig. Gen. Neil Thurgood, the Army's Program Executive Officer (PEO) for Missiles and Space, America's principal foes have developed advanced digital jamming far beyond old-school analog technology.
That advanced tech is not only capable of blocking missile defense radars from intercepting incoming signals, but can also fool the defenses with a false radar pulse.
Essentially, Russian and Chinese jammers can trick US missile defense networks into firing at empty sky.
To improve those defenses, the Army is hoping to streamline its computer networks. Testing the Integrated Air and Missile Defense Battle Command System, the exercise at White Sands experimented with combining multiple radars into one, fluid, detection apparatus.
"Today, we don't hook all those together. We don't see one single air picture, one composite track for one target," Thurgood told Breaking Defense. "[But in the exercise] we had the Patriot weapon platform, the Sentinel [radar], the Avenger weapon platform, all linked to IBCS, all making the composite track, one track from all the sensors, and we practiced engagements..."
By relying on multiple radar platforms, it will prove more difficult to fool any one installation.
Of course, even with new ideas for improvement, it could still take over a year to fully analyze the results of the exercise, and even longer to implement any corrections.
This isn't the first sign that Western missile defense systems need drastic overhauls. On Wednesday, the head of the North American Aerospace Defense (NORAD) announced that the organizations missile defense program "will not work" against an enemy attack.
While NORAD's concerns don't involve radar jamming, specifically, it is adopting a similar strategy to fix its flaws. By developing a global network capable of quickly transmitting targeting data, the defense organization hopes to improve its response time.
"We have the technology," Admiral Bill Gortney told Breaking Defense. "The technologies are probably all out there. It's getting it aligned."
