A Better Missile Defense for a Safer Europe

Washington

THE future of missile defense in Europe is secure. This reality is contrary to what some critics have alleged about President Obama?s proposed shift in America?s missile-defense plans on the continent — and it is important to understand how and why.

First, to be clear, there is now no strategic missile defense in Europe. In December 2006, just days after becoming secretary of defense, I recommended to President George W. Bush that the United States place 10 ground-based interceptors in Poland and an advanced radar in the Czech Republic. This system was designed to identify and destroy up to about five long-range missiles potentially armed with nuclear warheads fired from the Middle East — the greatest and most likely danger being from Iran. At the time, it was the best plan based on the technology and threat assessment available.

That plan would have put the radar and interceptors in Central Europe by 2015 at the earliest. Delays in the Polish and Czech ratification process extended that schedule by at least two years. Which is to say, under the previous program, there would have been no missile-defense system able to protect against Iranian missiles until at least 2017 — and likely much later.

Last week, President Obama — on my recommendation and with the advice of his national-security team and the unanimous support of our senior military leadership — decided to discard that plan in favor of a vastly more suitable approach. In the first phase, to be completed by 2011, we will deploy proven, sea-based SM-3 interceptor missiles — weapons that are growing in capability — in the areas where we see the greatest threat to Europe.

The second phase, which will become operational around 2015, will involve putting upgraded SM-3s on the ground in Southern and Central Europe. All told, every phase of this plan will include scores of SM-3 missiles, as opposed to the old plan of just 10 ground-based interceptors. This will be a far more effective defense should an enemy fire many missiles simultaneously — the kind of attack most likely to occur as Iran continues to build and deploy numerous short- and medium-range weapons. At the same time, plans to defend virtually all of Europe and enhance the missile defense of the United States will continue on about the same schedule as the earlier plan as we build this system over time, creating an increasingly greater zone of protection.

Steady technological advances in our missile defense program — from kill vehicles to the abilities to network radars and sensors — give us confidence in this plan. The SM-3 has had eight successful tests since 2007, and we will continue to develop it to give it the capacity to intercept long-range missiles like ICBMs. It is now more than able to deal with the threat from multiple short- and medium-range missiles — a very real threat to our allies and some 80,000 American troops based in Europe that was not addressed by the previous plan. Even so, our military will continue research and development on a two-stage ground-based interceptor, the kind that was planned to be put in Poland, as a back-up.

Moreover, a fixed radar site like the one previously envisioned for the Czech Republic would be far less adaptable than the airborne, space- and ground-based sensors we now plan to use. These systems provide much more accurate data, offer more early warning and tracking options, and have stronger networking capacity — a key factor in any system that relies on partner countries. This system can also better use radars that are already operating across the globe, like updated cold war-era installations, our newer arrays based on high-powered X-band radar, allied systems and pos
