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.”
