U.S. Navy deploys system to detect North Korean missile

WASHINGTON — The U.S. military Tuesday moved ships into position off the coast of North Korea to detect the launch of any long-range ballistic missiles and prepared its new, unproven missile-interception system to attempt a response if necessary.

It is apparently the first time that the U.S. government has readied its rudimentary missile-defense system other than to test it.

The South Korean government expressed doubt that North Korea is even preparing a test launch of its first intercontinental missile. It suggested that the government of Kim Jong Il might be only readying to send a satellite into space.

Two U.S. Navy ships with sensors that would swiftly detect and track a missile's flight were operating off the North Korean coast Tuesday, a Pentagon official said. They are the USS Curtis Wilbur and the USS Fitzgerald, both Arleigh Burke-class guided missile destroyers based in Japan.

Also, as part of a long-planned exercise, the Navy has three carrier battle groups operating near Guam in the Western Pacific for the first time since the Vietnam War, along with dozens of aircraft, including heavy bombers.

Pentagon officials said steps had been taken to ready the U.S. interceptors in much the same way that they would proceed for a test of the system — which is still being built — because of recent satellite imagery indicating that North Korea might be preparing a test launch.

But they declined to confirm a Washington Times story Tuesday that said the system had recently been activated, and that the Bush administration is considering shooting down the North Korean missile.

There are nine interceptor missiles based in Alaska and two in California. They are at the core of a complex system that connects launch data from satellites and radars on land and aboard ships, and transmits the data to command-and-control facilities. The system has not successfully intercepted a missile in its current configuration.

U.S. government officials said it isn't yet clear whether North Korea will send a missile aloft — or if it does, whether it would head anywhere near U.S. territory.

Nor would the U.S. government want to risk an embarrassing failure of its system, they said.
