North Korea tested robotic sub capable of causing ‘radioactive tsunami’

North Korea tested a nuclear-capable robotic sub, which can cause a ‘super-powerful radioactive tsunami’ when exploding, North Korea’s state-run Voice of Korea radio said on Friday.

"This secret weapon is a nuclear-capable unmanned underwater assault craft. Its mission is to travel under water in secret and to perform an underwater explosion, creating a super-powerful radioactive tsunami and destroying the adversary’s ships and ports," the radio reported.

According to the report, the drone travelled to the testing range off the South Hamgyong Province on North Korea’s eastern coast. The submersible stayed under water for 59 hours, constantly changing its direction and maneuvering at the depth of 80-150 meters. On the afternoon of March 23, it reached its destination in the bay of Hongwon, which imitated a notional enemy’s port, and its test charge was detonated remotely under water.

The development of the submersible has been under way in North Korea since 2012.

North Korean leader Kim Jong Un oversaw the trials. According to the report, he "warned the United States and South Korea about the need to stop reckless drills near North Korea."[TASS]
