Nampo (MLS-II)

The Nampo-class submarine, also known as the Hero Kim Kun Ok, is a large conventional attack submarine launched by North Korea in 2023. It is speculated to be capable of launching submarine-launched ballistic missiles (SLBMs) and potentially serving as a minelayer or special operations platform.

Developed as part of North Korea's strategic ambition to establish a survivable sea-based nuclear deterrent, the vessel represents a heavily modified derivative of the aging Soviet-designed Romeo-class submarine. Officially launched in September 2023 as Hull 841, the submarine was assigned to the Korean People's Army Navy's East Sea Fleet to undergo integration and sea trials. While it has not seen combat, the platform is configured with ten vertical launch tubes intended to deploy nuclear-capable cruise missiles and short-range ballistic missiles. Currently active in testing phases, the vessel remains a key component of Pyongyang's asymmetric naval doctrine despite international skepticism regarding its acoustic stealth and overall operational viability.
