North Korea registers 13 submarines with International Maritime Organization: strategic move or global signal?.

According to information published by VOA Korea on August 28, 2024, North Korea has recently registered 13 of its submarines with the International Maritime Organization (IMO) for the first time, a move that may indicate Pyongyang's intention to legitimize its submarine fleet and potentially prepare for overseas operations.

The 11 Sang-O II class submarines, which operate primarily in coastal waters around the Korean Peninsula, were reported to have been constructed between 2004 and 2006.

However, experts note that these are likely upgraded versions of older models originally built in the 1990s. The 8.24 Yongung is known for being involved in North Korea's previous tests of submarine-launched ballistic missiles (SLBMs), although its construction year is listed as 2016. The newest submarine, the Hero Kim Kun Ok, was recorded as being built in 2023 and is reportedly equipped with 10 SLBM launch tubes.

North Korea's sudden decision to register these submarines with the IMO raises several questions, especially since only a portion of its estimated fleet of 70 submarines has been listed.

Strategic Implications and Speculations

There is also speculation that North Korea might be preparing for joint submarine exercises with China and Russia. While most of the registered submarines are older and not suited for long-distance operations, they could still be operational in the coastal waters of neighboring countries.

Some experts remain skeptical, questioning the purpose behind North Korea's decision to undergo what is typically considered an unnecessary administrative procedure.

The State of North Korea's Submarine Fleet

Many of North Korea's submarines, including those recently registered, are aging and might not be capable of sustained operations far from home waters.

The two submarines capable of carrying ballistic missiles still rely on conventional diesel power, which limits their operational range and logistical sustainability outside North Korean waters.

While North Korea has showcased these submarines as part of its modern military arsenal, there remain doubts about their operational reliability and effectiveness. While the "August 24th Hero Submarine" has proven its ability to launch a solid-fuel ballistic missile, its single launch tube severely limits its offensive capabilities.
