US defence secretary Chuck Hagel has announced plans to bolster US missile defences in Alaska in response to a growing nuclear threat from North Korea.

The US will add 14 interceptors to a missile defence site in Alaska and deploying a radar tracking station in Japan.

The decision to add 14 new anti-missile interceptors at Fort Greely in Alaska 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.

Mr 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,” Mr Hagel said.

He said the additional interceptors would be deployed by the end of 2017, but did not say when their deployment would start.

Mr Hagel also said the Un ited States would move forward with a plan announced by his predecessor last year to deploy a second missile defense radar in Japan.

Mr Hagel's announcement comes a week after North Korea threatened the United States with a pre-emptive nuclear strike and a month after Pyongyang conducted its third nuclear test, in defiance of UN resolutions. It conducted a launch of a long-range rocket in December.

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," James Miller, the defence department's policy chief, told the Atlantic Council on Tuesday.

Mr 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," Mr Miller said in his address.
