North Korea conducted their first ballistic missile test of 2017 on Sunday, firing what experts believe was an IRBM (intermediate-range ballistic missile) into the Sea of Japan.

The missile flew just over three hundred miles before crashing into the waterway that bears the name of the nation many believe Kim Jong Un had in mind when hitting the button for the test: Japan.  The Japanese Prime Minister, Shinzo Abe, was continuing his visit with the President of the United States as the test was conducted.

North Korean officials labeled the test a success, calling the missile a “surface-to-surface medium-to-long-range ballistic missile” in their state-owned media.  The missile, called the Pukguksong-2, is the latest missile platform to come from North Korea, and is believed to be capable of housing a nuclear warhead.

“It’s yet unclear what missile was tested,” said Thomas Karako, a missile expert at the Center for Strategic and International Studies in Washington. “What is certain is that North Korea has now begun 2017 by continuing the aggressive pace of missile testing they’ve shown in recent years.”

Though it is important to note that experts cannot be certain of the specifics regarding the missile, a combination of information provided by North Korean officials and intelligence gathered from other sources, including tracking of this most recent missile test, have given experts enough to make some credible guesses as to the capabilities of the missile.

Estimates suggest that the missile’s potential range could be anywhere from 1,800 to 3,400 miles, keeping the continental United States outside of its potential range, but easily placing South Korea and Japan in its cross hairs.  It is believed that a relatively short test range of approximately three hundred miles was chosen to limit the potential for the missile accidentally landing in Japan.

As a result, South Korea, Japan and the United States have requested an emergency meeting of the UN Security Council to discuss the test.

KCNA, the official North Korean media outlet, stated that Kim Jong Un “expressed great satisfaction” after the test launch, going on to say that the missile “adds to the tremendous might of the country.”
