South Korea’s military says it is highly likely that North Korea has tested a missile designed for launch from a submarine. It said the launch appeared to have taken place early Wednesday near the city of Wonsan on the country’s eastern coast. South Korea says the missile traveled about 450 kilometers and reached a height of about 910 kilometers. David Wright of the Union of Concerned Scientists said that although the missile did not travel far, it was able to do so. “This would classify the missile as a medium range missile,” he said. It is not clear if North Korea launched the missile from a submarine or an underwater structure. If confirmed, it could be the first time since 2017 that the North has tested a missile that is able to travel more than a “short” distance.
