North Korea Builds Two New Frigates Simultaneously as It Expands Naval Capabilities with Russian Assistance.


North Korea is undergoing an unprecedented modernization of its naval fleet with the simultaneous construction of two distinct frigates at the Nampo shipyard. These new surface vessels mark a strategic shift in Pyongyang’s maritime doctrine, aimed at strengthening its power projection and defense capabilities in response to regional threats. During an inspection visit on March 8, 2025, Kim Jong-Un reviewed the progress of these projects and reaffirmed the importance of naval power in national defense, emphasizing the need for a fleet capable of operating under modern naval warfare conditions.

Images released by state media show two ships under construction, each in a different section of the shipyard. The first, which appears to be at an advanced stage, features a large superstructure with a design seemingly intended to reduce radar signature. It is expected to integrate modern systems, including a fixed-panel radar, a configuration not previously seen in the North Korean Navy, and a vertical launching system (VLS) capable of deploying both cruise missiles and advanced guided surface-to-air missiles. With an estimated displacement of over 3,000 tons, this frigate would be the largest surface combatant ever built by North Korea. Its design suggests an effort to align with the technological standards of more developed navies while enhancing the country's blue-water capabilities.

The second frigate, still under construction in another hall of the same shipyard, appears to be part of a separate program. The installation of a new clad structure in this section, identified by analysts in the previous year, indicates that construction on this vessel has recently accelerated. Its design and configuration are less advanced than those of the first ship, suggesting that it may be a more conventional variant, likely designed for patrol and coastal defense missions. However, it also incorporates modernized elements, reflecting a broader effort to enhance the North Korean surface fleet.

This ambitious naval program is part of a wider modernization initiative, which also includes the construction of a 7,000-ton nuclear-powered strategic submarine. Currently being assembled at Sinpo South, this submarine is expected to carry up to ten ballistic missiles, providing Pyongyang with a more difficult-to-detect underwater strike capability. The commissioning of this submarine would significantly strengthen the country's nuclear deterrence strategy and mark a turning point in its submarine capabilities.

The simultaneous acceleration of these naval projects is partly attributed to growing cooperation with Russia. Historically, North Korea has received technological transfers from China and the former Soviet Union to develop its naval capabilities. Today, presumed Russian involvement in these projects could explain the rapid integration of advanced technologies, particularly the VLS and modern radar systems. This development suggests an intensification of ties between Moscow and Pyongyang, reinforcing North Korea’s navy amid rising geopolitical tensions.

Currently, the Korean People’s Navy relies primarily on an aging fleet dominated by Najin- and Nampo-class frigates. The Najin-class frigates, introduced in the 1970s, have undergone partial modernizations, including the integration of Kh-35 anti-ship missiles on certain units. However, with a displacement of around 1,500 tons, these ships exhibit clear technological limitations against modern threats. The Nampo-class frigates, more recent but produced in limited numbers, remain largely undocumented due to the secrecy surrounding North Korea’s naval programs. In comparison, the new frigates under construction represent a significant technological leap, enhancing the country's ability to conduct more effective naval operations.

Alongside these developments, North Korea has also integrated a modernized frigate into its fleet, Patrol Ship No. 661, part of the Amnok-class. This vessel, among the most advanced in the North Korean Navy, features a design inspired by foreign models and a diversified weapons system. It is equipped with eight anti-ship missiles, six short-range surface-to-air missiles, a 76mm naval gun, two rapid-fire anti-aircraft systems, and anti-submarine rocket launchers, providing North Korea with improved maritime and coastal operational capabilities. The commissioning of this frigate coincided with North Korea’s participation in Russia’s "Ocean-2024" naval exercises, an event that marked the country's first such involvement and highlighted a growing military partnership between Moscow and Pyongyang.

The simultaneous development of these frigates and the strategic nuclear submarine comes at a time of rising regional tensions, particularly with the United States and South Korea increasing their joint military exercises. Ahead of the Freedom Shield drills, North Korea appears to be signaling its ability to modernize its navy despite international sanctions and diplomatic pressures.

This accelerated naval modernization marks a break from Pyongyang’s traditional military doctrine, which has historically focused on land-based and submarine deterrence. The commissioning of these new warships represents a major transformation for the Korean People’s Navy, which has long been limited to asymmetric and coastal operations but now appears to be shifting towards a broader enhancement of its blue-water capabilities.

With these frigates and its submarine program, North Korea is moving beyond a purely defensive posture to establish a more diverse and sophisticated naval fleet. This evolution, combined with technical and strategic support from Russia, could alter the regional naval balance and force the United States and South Korea to reassess their maritime defense and presence strategies.
