S. Korea: North Korea test-fired sub missile

North Korea flight-tested a ballistic missile that was likely fired from a submarine on Saturday, South Korea’s military said, continuing a provocative streak in weapons demonstrations that may culminate with a nuclear test in the coming weeks or months.

South Korea’s Joint Chiefs of Staff said the launch occurred from waters near the eastern port city of Sinpo, where North Korea has a major shipyard building submarines. It said the short-range missile flew 372 miles at a maximum altitude of 37 miles but it didn’t immediately provide details about the submarine that would have been involved in the launch.

The U.S. military’s IndoPacific Command said while the launch did not pose an immediate threat to U.S. personnel or territory, or to its allies, it “highlights the destabilizing impact of the DPRK’s illicit weapons program. The U.S. commitment to the defense of the Republic of Korea and Japan remains ironclad.”
