A national defence science research institute in the DPRK carried out a test of underwater strategic weapon system from April 4 to 7.

The underwater nuclear attack drone "Haeil-2" entered into the test in Kajin Port, Kumya County, South Hamgyong Province in the afternoon on April 4. It cruised 1 000 km of simulated underwater distance in elliptical and "8" patterns set in the East Sea of Korea for 71 hours and 6 minutes. In the afternoon on April 7 it arrived in the waters off Ryongdae Port, Tanchon City, South Hamgyong Province, the place of simulated target, where the test warhead accurately detonated underwater.

The test perfectly proved the reliability of the underwater strategic weapon system and its fatal attack ability.

The system will serve as an advantageous and prospective military potential of the armed forces of the DPRK essential for containing all evolving military actions of enemies, removing threats and defending the country.
