North Korea fires suspected intermediate-range ballistic missile

South Korea’s Joint Chiefs of Staff said the missile was launched from an area near the North Korean capital, Pyongyang, and flew about 600 kilometers (372 miles) before landing in the sea between the Korean Peninsula and Japan.

The South Korean military didn’t immediately provide other flight details, including whether it had assessed if North Korea had tested the missile at less than its full capacity or used new technologies.

Japan's Defense Ministry gave more details in its assessment, saying the missile flew about 650 kilometers (403 miles) while reaching a maximum altitude of 100 kilometers (62 miles) before landing in waters outside of Japan's exclusive economic zone. The Japanese military didn't immediately say whether it assessed the missile as intermediate range or something else.

The North had said last month that it tested a solid-fuel engine for its new-type intermediate-range hypersonic missile, which, if perfected, could reach the U.S. Pacific military hub of Guam and beyond.It was the North’s first known launch event since March 18, when North Korean leader Kim Jong Un supervised a live-fire drill of artillery systems designed to target South Korea’s capital.

Japan’s coast guard shared an assessment of the country’s Defense Ministry that the missile has already landed but still urged caution for vessels passing the area.

Japanese Prime Minister Fumio Kishida told reporters that no damage related to the missile has been reported. He said North Korea’s frequent missile launches "threaten the peace and safety of not only Japan but also the region and the international security."

In recent years, North Korea has been focusing on developing more weapons with built-in solid propellants. Those weapons are easier to move and hide and can be made to launch quicker than liquid-propellant missiles, which need to be fueled before launch and cannot stay fueled for long periods of time.

Kim has also vowed to acquire hypersonic missiles that can overwhelm its adversaries’ missile defense systems. Other weapons North Korea have tested this year include cruise missiles and "super-large" multiple rocket launchers aimed at the Seoul capital area.

The latest launch came two days after North Korea reaffirmed its plans to launch several reconnaissance satellites this year. South Korea’s military said Monday there were no signs that a satellite launch is impending at the North’s main launch facility in the northwest.

Kim has described satellites as crucial for monitoring U.S. and South Korean military movements and enhancing the threat of his nuclear-capable missiles. Last November, North Korea put a military spy satellite into orbit for the first time.
