N. Korea's 'new missile' has unprecedented range: experts

Seoul : North Korea said Monday it had successfully tested a new type of rocket in its latest missile launch, as analysts said it showed an unprecedented range that brought US bases in the Pacific within reach.

Sunday's launch was of a "new ground-to-ground medium long-range strategic ballistic rocket" named the Hwasong-12, the official Korea Central News Agency (KCNA) said.

Leader Kim Jong-Un personally oversaw the test, it said, and "hugged officials in the field of rocket research, saying that they worked hard to achieve a great thing".

The isolated North is under multiple sets of United Nations sanctions over its nuclear and missile programmes, which have triggered global alarm.

The missile was launched on an unusually high trajectory, with KCNA saying it flew to an altitude of 2,111.5 kilometres and travelled 787 kilometres before coming down in the Sea of Japan (East Sea).

That suggests a range of 4,500 kilometres (2,800 miles) or more if flown for maximum distance, analysts said.

Aside from space launches, Jeffrey Lewis of the Middlebury Institute of International Studies in the US told AFP: "This is the longest range missile North Korea has ever tested."

On the respected 38 North website, aerospace engineering specialist John Schilling said it appeared to demonstrate an intermediate-range ballistic missile that could "reliably strike the US base at Guam" in the Pacific.

"More importantly," he added, it "may represent a substantial advance to developing an intercontinental ballistic missile (ICBM)".
