Geller: Successful missile defense test: Welcome news as rogue threats advance


You wouldn’t know it from the lack of headlines, but the U.S. Navy and Missile Defense Agency recently made history with something that should help make all Americans safer.

Specifically, they successfully shot down an intercontinental-range ballistic missile using the Navy’s Standard Missile SM-3 Block IIA interceptor launched from a Navy destroyer.

Missile defense is nothing new, of course. The U.S. has had one for years. But until now, we’ve tested its ability to defend the homeland from incoming missile attacks only with the Ground-based Midcourse Defense system.

This system consists of 44 ground-based interceptors deployed in Alaska and California, poised to intercept incoming missiles in their midcourse phase as they fly through space before reentering the atmosphere.

Gen. Terrence O’Shaughnessy, former commander of U.S. Northern Command, certified to the U.S. Senate earlier this year that the Ground-based Midcourse Defense system can defend against a North Korean threat today — but the future is less certain. Two main factors drive this uncertainty.

First, the North Korean threat is visibly advancing, as Pyongyang’s display of its new “monster” ICBM in a parade last month demonstrates.

Second, the fate of the Ground-based Midcourse Defense system is uncertain. The Pentagon is pursuing the Next Generation Interceptor program to both increase the capacity of our missile defense system to 64 interceptors and eventually replace our current interceptors, which are old.

The Missile Defense Agency aims to begin fielding the Next Generation Interceptor by 2028, but it would be naive to assume such an acquisition program would be free from risk of delay.

Enter the SM-3 Block IIA interceptor. This year, the Pentagon proposed developing a homeland defense “underlay” — a second layer of interceptors that can take a shot at incoming missiles if our Ground-based Midcourse Defense system’s interceptors miss. The SM-3 Block IIA interceptor can launch from Navy destroyers or from Aegis Ashore missile defense systems, and is originally designed to intercept theater-range missiles.

The Missile Defense Agency and Navy accomplished a remarkable feat with this intercept, marking the first use of a theater-range, ship-launched interceptor to shoot down a long-range missile.

The Missile Defense Agency can now proceed with a more complex test, potentially against an ICBM target armed with decoys or other missile-defense countermeasures.

The next administration will then have to decide how to employ the SM-3 interceptor to defend the homeland. Its use can be as simple as maintaining the ability to deploy Aegis ships armed with these interceptors to the Pacific in the event of brewing North Korean aggression.

The next administration could also pursue a series of Aegis Ashore deployments across the United States to establish a permanent SM-3 Block IIA intercept capability.

This test already provoked blowback from the Russians and Chinese. They claim advancing U.S. missile defenses will threaten strategic stability by encouraging the United States to launch a first strike without fear of assured retaliation. Such accusations must be dismissed as folly.

Despite these charges, an underlay of SM-3 interceptors simply cannot defend against Russia’s and China’s advanced arsenals, whose sizes alone can overwhelm U.S. homeland defense. Especially as Russia and China hypocritically advance missile interceptors of their own, the United States must not let Russia and China weigh in on our pursuit of an underlay to defend against North Korea.

As preparations take place for the next administration and a new Congress, homeland missile defense must remain a top priority. With the success of this test, pursuing the SM-3 Block IIA interceptor as an additional means of homeland defense is now a potential path towards a stronger homeland defense.
