The North Korean government, by way of their state-run news agencies KCNA and Korean Central Telivision, has released a four-minute long video of the launch of their newest missile platform, confirmed by U.S. intelligence to be a true ICBM, called the Hwasong-14.

The launch, which occurred on Monday, demonstrated a significant leap forward in North Korea’s missile technology.  It reached a maximum altitude of over 1,700 miles before reentering the earth’s atmosphere and splashing down somewhere in the sea between North Korea and Japan, some 590 miles from its launch point.  Based on the missile’s trajectory and the altitude it reached, U.S. experts estimate North Korea’s new ICBM could easily strike targets at a range of greater than 4,000 miles – placing almost the entirety of Alaska within their scope, and requiring very little to extend its reach onto the mainland United States.

“A flight time of 37 minutes would require it to reach a maximum altitude of more than 2,800 km (1700 miles),” missile expert David Wright, a senior scientist at the Union of Concerned Scientists, a science advocacy group in Cambridge, Massachusetts wrote in a blog post yesterday.

“So if the reports are correct, that same missile could reach a maximum range of roughly 6,700 km (4,160 miles) on a standard trajectory. That range would not be enough to reach the lower 48 states or the large islands of Hawaii, but would allow it to reach all of Alaska.”
