North Korea Tests Nuclear-Capable Underwater Drone in Simulated Attack.

North Korea claims to have successfully tested an underwater drone capable of carrying a nuclear warhead that could create a "radioactive tsunami." However, analysts are skeptical of the claim as North Korea provided no proof. The drone, called the "Unmanned Underwater Nuclear Attack Craft 'Haeil,'" has been in development since 2012 and has undergone more than 50 tests in the past two years. The drone can be deployed from any port or towed by a surface ship to begin its operations. Pyongyang's nuclear weapons development is necessary to counter "the reckless military provocations being escalated by the U.S. and the South Korean authorities," according to the KCNA report.
