North Korea made headlines by launching its first operational “strategic nuclear attack submarine,” named submarine No. 841 and named for former North Korean Navy commander Hero Kim Kun Ok.
Submarine No. 841 is a modified version of the Soviet-era Romeo-class submarine, which North Korea acquired from China in the 1970s and later began producing domestically.
Its design has 10 launch tube hatches, indicating that it is likely armed with ballistic missiles and cruise missiles.
