U.S. Defense Secretary Chuck Hagel announced plans on Friday to bolster U.S. missile defenses in response to a growing nuclear threat from North Korea, adding 14 interceptors to a missile defense site in Alaska by 2017 and deploying a radar tracking system in Japan.
The decision to add 14 new anti-missile interceptors at Alaska's Fort Greely amounts to a reversal of an Obama administration decision in 2010 to stop expansion of the missile field there at 30 interceptors.
The Bush administration had planned to deploy 44 total interceptors. Hagel said the decision to deploy all 44 interceptors came as a result of the growing threats from Iran and particularly North Korea, which tested a third nuclear device last month and launched a rocket that put a satellite in orbit in December.
“The reason that we’re doing what we’re doing ... is to not take any chances, is to stay ahead of the threat,” Hagel said.
He said the additional interceptors would be deployed by the end of 2017, but did not say when their deployment would start.
Hagel also said the United States would move forward with a plan announced by his predecessor last year to deploy a second missile defense radar in Japan.
Hagel’s announcement came a week after North Korea threatened the United States with a pre-emptive nuclear strike.
Experts say North Korea is years away from being able to hit the continental United States with a nuclear weapon, despite a decades-long push toward a nuclear capability.
But its fiery rhetoric and aggressive testing have increased tension with the United States and South Korea.
“North Korea’s shrill public pronouncements underscore the need for the U.S. to continue to take prudent steps to defeat any future North Korean ICBM,” or intercontinental ballistic missile, James Miller, the Defense Department’s policy chief, told a think-tank, the Atlantic Council, on Tuesday.
Miller - also citing tensions with Iran - said the Pentagon was initiating congressionally mandated environmental impact studies for three alternative sites for deploying additional ground-based interceptors, if needed.
“These studies will allow us to shorten the timeline to build a new missile field on the East Coast or to add interceptors in Alaska, should either approach become necessary due to further future increases in the threat from Iran and North Korea,” Miller said in his address.
