The Academy of Defence Science of the DPRK conducted another test of underwater strategic weapon system from March 25 to 27.

The underwater nuclear attack drone "Haeil-1", deployed for the test in Wonsan Bay on the afternoon of March 25, reached the target point in the waters off Hwadae County of North Hamgyong Province on the morning of March 27 after cruising along a jagged and oval course simulating the distance of the 600 kilometers in the East Sea of Korea for 41 hours and 27 minutes and correctly set off the test warhead underwater.

Through the test, all tactical and technical specifications and underwater navigational and technical indices were correctly estimated and the reliability and safety of the weapon system were verified.
