Secretary of Defense Gates inspects a GBI at Ft. Greely, AK
Unlike the recent massive Juniper Cobra missile defense exercise which tested our ballistic missile defense system (BMDS) against short- and medium-range Iranian missile threats, the US Missile Defense Agency (MDA) will soon conduct an unprecedented test:
WASHINGTON (Reuters) - The United States will test its core missile defenses for the first time in January against a simulated long-range Iranian attack, a top Pentagon official said on Monday, amid tensions with Tehran.
Speaking at the Reuters Aerospace and Defense Summit in Washington, Army Lieutenant General Patrick O'Reilly, the head of the Missile Defense Agency, said the roughly $150 million test was a departure from the more standard scenario of a North Korean attack.
There is a reason that our longest range interceptors, the 3-stage Ground-based Interceptors (GBIs), were first deployed in Alaska and California. Ever since the late 1990s, the North Korean ICBM threat has always been the most immediate one to CONUS. The systems engineering, wargaming, and eventual deployment of GBIs exclusively on the West Coast were specifically executed to counter this growing threat.
Which makes this upcoming test so very remarkable:
It also would be more difficult testing the U.S. Ground-based Midcourse Defense (GMD) system against a missile that would be faster and more direct as it races toward the United States than a simulated strike from North Korea.
"Previously, we have been testing the GMD system against a North Korean-type scenario," O'Reilly said.
"This next test ... is more of a head-on shot like you would use defending against an Iranian shot into the United States. So that's the first time that we're now testing in a different scenario."
Now wait one damned minute.
A mere three months ago, President Obama decided to scrap our long-range interceptors in Europe (again, specifically designed to counter Iranian ICBMs bound for the US east coast) because the long-range Iranian threat no longer existed:
The intelligence community now assesses that the threat from Iran's short- and medium-range ballistic missiles, such as the Shahab-3, is developing more rapidly than previously projected. This poses an increased and more immediate threat to our forces on the European continent, as well as to our allies. On the other hand, our intelligence assessment also now assesses that the threat of potential Iranian intercontinental ballistic missile capabilities has been slower to develop than was estimated in 2006.
If Iraninan ICBMs are no longer a threat, why this test?
Well, the easy answer is we plan these tests years in advance, and this GBI test was laid down long before Obama's pronouncement. That said, there are some disconcerting optics here. Conducting an expensive test against a recently rubbished threat just doesn't look good.
Besides having been on the slate for a while, there's another possible reason for this test.
As I have argued before, Obama's new European BMD architecture may do an adequate job defending Europe from Iranian missile threats, but it does nothing to protect the Eastern United States. Only the long-haul GBIs have the horsepower to engage fast, high-flying ICBMs. While Aegis-based SM-3s and THAADs do an excellent job against short- and medium-range missiles, they simply can't beat the massive GBIs in the ICBM scenario.
Therefore, I'd bet some smarty at MDA doesn't exactly discount the Iranian ICBM threat as readily as the President and the SecDef do. With European-based GBIs now off the table, American-based GBIs must fill the defensive void. Nothing else can do the job, so they damned well better work.
Rather than the standard NK simulation where we fire the target ICBM from Kodiak Island, Alaska and intercept with a GBI from Vandenberg AFB, California, this target will come screaming across the Pacific from Reagan Test Site on Kwajalein Atoll:
The test would fire an interceptor missile from Vandenberg Air Force Base in California at a simulated incoming missile, launched from the Marshall Islands in the Pacific Ocean. An aide to O'Reilly estimated the cost at about $150 million.
Experts compare the simulation to a bullet hitting another bullet in space. O'Reilly said the goal was to destroy the target over the north central Pacific when the missiles had a combined closing speed of more than 17,000 miles per hour.
"Whenever we have a situation where we're taking on a missile more head on than from the side, that increases the challenges," O'Reilly said.
Stay tuned.
