In a high-profile display of advancing military ambitions just days before Chinese President Xi Jinping’s scheduled visit to Pyongyang, North Korean leader Kim Jong Un has overseen sea trials of a recently repaired 5,000-ton guided-missile destroyer and doubled down on pledges to build out a nuclear-capable navy, according to state-run media reports released Saturday.
The vessel in question, the Kang Kon, underwent operational capability tests on Thursday, the Korean Central News Agency (KCNA) confirmed. Kim was joined during his inspection by his teenage daughter Kim Ju Ae, whose growing public presence has reinforced widespread speculation among South Korean intelligence officials that she is being prepared as Kim Jong Un’s eventual successor.
During his remarks to military personnel and shipbuilders, Kim emphasized an urgent push to accelerate naval modernization, framing a robust nuclear-armed maritime force as a core pillar of North Korea’s overall nuclear deterrence strategy. He stressed that the country’s navy must be equipped to deliver a lethal, unpredictable strike against rival forces both on and beneath the sea at any time. The expansion of naval capabilities, Kim noted, is a central priority outlined in the five-year defense development plan adopted by the ruling Workers’ Party of Korea at its congress earlier this year. That blueprint, he added, calls for constructing larger 10,000-ton-class destroyers and advancing development of classified underwater weapons systems.
Notably, the KCNA report did not include direct commentary from Kim on North Korea’s longstanding regional rivals, the United States and South Korea, even as tensions over Pyongyang’s nuclear program remain high and inter-Korean diplomatic engagement remains frozen.
The reveal of the warship trials comes on the heels of two linked developments that have underscored shifting regional geopolitics: the official confirmation of Xi Jinping’s Monday visit to North Korea, and the recent unveiling of what South Korea’s military assesses is a new uranium enrichment facility for nuclear weapons production. During his visit to that undisclosed site, Kim pledged to grow North Korea’s nuclear arsenal “at an exponential rate,” a declaration that experts interpret as a deliberate move to solidify Pyongyang’s status as a recognized nuclear weapons state ahead of high-level talks with Beijing. Xi’s upcoming trip marks a key step in China’s efforts to strengthen diplomatic and economic ties with its isolated, nuclear-armed neighbor, at a time when Kim has increasingly deepened his military and political alignment with Russia, including the provision of troops and military hardware to support Moscow’s campaign in Ukraine.
The Kang Kon is the second 5,000-ton-class destroyer North Korea has unveiled since 2023, following the launch of the Choe Hyon. Kim previously celebrated the Choe Hyon’s development as a transformative step that extends the operational range and preemptive strike capacity of North Korea’s nuclear force. State media says both vessels are engineered to carry a full suite of weaponry, including anti-aircraft systems, anti-ship missiles, and nuclear-capable ballistic and cruise missiles. However, independent defense analysts have raised persistent questions about the ships’ actual operational effectiveness.
The Kang Kon’s journey to sea trials has been marked by setback: the vessel suffered significant damage during a botched launch ceremony at the northeastern port of Chongjin in May 2023, a failure Kim publicly condemned as “criminal.” Pyongyang announced the ship had been repaired and relaunched in June 2023, but outside experts continue to cast doubt on whether it is fully combat-ready. Despite the setback, Kim has already ordered the construction of two additional 5,000-ton-class destroyers to expand the navy’s conventional and nuclear strike capacity.
