North Korea’s nuclear submarine is a strategic nuclear submarine (SSBN), a submarine capable of nuclear propulsion and nuclear missile launch.
Nuclear-powered submarines are, in theory, submarines that can submerge until they run out of food, and their speed is around 35 knots, making them powerful as they are faster than diesel submarines.
We also need to quickly create a nuclear attack submarine (SSN).
It must be tracked under the East Sea and quickly sunk in case of emergency.
