On August 18, 2025, North Korean leader Kim Jong Un stepped aboard his country’s latest naval pride, the 5,000-tonne destroyer Choe Hyon, at the western port of Nampo. The visit, widely covered by state media and international outlets alike, unfolded against a backdrop of rising tensions on the Korean Peninsula, as the United States and South Korea kicked off their annual Ulchi Freedom Shield military exercises. Kim’s public appearance and fiery rhetoric offered a window into North Korea’s evolving military ambitions—and its enduring anxieties about the intentions of its southern neighbor and the United States.
The Choe Hyon, first unveiled in April 2025, represents a significant leap in North Korea’s naval capabilities. According to the Korean Central News Agency (KCNA), the warship is designed to accommodate a range of advanced weapons systems, including nuclear-capable cruise and ballistic missiles, as well as anti-air and anti-naval armaments. Kim Jong Un, photographed touring the ship’s bridge, captain’s office, and even sitting on a bunk bed, expressed satisfaction with the vessel’s progress and ordered performance tests to take place in October.
State media reported that the Choe Hyon is expected to enter active service in 2026. Its unveiling comes as part of a broader push to modernize the North Korean navy—a program that has encountered both triumphs and setbacks. In May, a separate destroyer of the same class, the Kang Kon, suffered damage during what Kim described as a “criminal” launch ceremony at the northeastern port of Chongjin. The incident, which Kim said “brought the dignity and self-respect of our state to a collapse,” prompted a hasty repair and relaunch in June. Despite the regime’s assurances, outside experts remain skeptical about the Kang Kon’s operational status.
Not content to rest on these developments, North Korea is reportedly pressing ahead with the construction of a third Choe Hyon-class destroyer, with completion targeted for the coming months. According to KCNA, Kim reviewed these efforts during his Nampo visit and reaffirmed his commitment to expanding the navy’s operational reach and preemptive strike capabilities.
But Kim’s shipboard tour was more than a routine inspection. It served as a stage for his latest denunciation of the US-South Korea joint military drills, which began the very same day. The Ulchi Freedom Shield exercise, running for 11 days and involving approximately 21,000 troops—including 18,000 South Koreans—is billed by its organizers as a defensive operation. It features large-scale live-fire training, computer-simulated command post operations, and incorporates lessons from recent conflicts, such as Russia’s war in Ukraine and the clash between Israel and Iran. The drills also address emerging threats like drone warfare, GPS jamming, and cyberattacks.
Kim, however, was having none of it. He blasted the exercises as an “obvious expression of their will to provoke war,” according to KCNA, and accused Washington and Seoul of escalating provocations by incorporating a “nuclear element” into their training. “The security environment around the DPRK is getting more serious day by day and the prevailing situation requires us to make a radical and swift change in the existing military theory and practice and rapid expansion of nuclearisation,” KCNA paraphrased Kim as saying. He vowed that North Korea would respond with “proactive and overwhelming” countermeasures, signaling an intent to accelerate the expansion of his country’s nuclear arsenal.
North Korea’s condemnation of the Ulchi Freedom Shield drills is nothing new. Pyongyang has long denounced such exercises as rehearsals for invasion, using them to justify its own military displays and weapons testing. Yet, the stakes feel higher this year, with the Choe Hyon’s nuclear capabilities front and center and the Korean Peninsula’s security environment growing ever more fraught.
South Korea, for its part, maintains that the exercises are purely defensive. The country’s new president, Lee Jae Myung, who took office in June, has expressed a desire to ease tensions with North Korea and restore a 2018 inter-Korean military agreement designed to reduce border clashes. The agreement, reached during a fleeting period of diplomacy, established buffer zones and no-fly areas along the border. However, it was suspended by Seoul in 2024 following a spate of North Korean provocations, including the launch of trash-laden balloons across the border. North Korea had already declared it would no longer abide by the deal, and efforts to revive talks have so far gone unanswered by Pyongyang.
President Lee’s administration has reiterated its view that the Ulchi Freedom Shield drills are defensive in nature. Kang Yu-jung, spokesperson for President Lee, stated that Seoul has “always regarded the Ulchi exercises as defensive” but declined to comment further on Kim’s remarks. Meanwhile, South Korea’s defense ministry has not released any new assessments regarding the Choe Hyon’s capabilities, and officials have remained largely silent in the face of Kim’s latest threats.
The reality on the ground is that the Korean Peninsula remains technically in a state of war, more than seventy years after the 1953 armistice. The Demilitarized Zone (DMZ) continues to divide the two Koreas—a stark reminder of unresolved tensions. North Korea’s pursuit of nuclear weapons and advanced delivery systems has only deepened the standoff, with international efforts to curb Pyongyang’s ambitions repeatedly stalling. Negotiations to wind down North Korea’s nuclear and missile programs have been at a standstill since a collapsed summit with then-US President Donald Trump in 2019.
In the meantime, North Korea’s military modernization shows no sign of slowing. Kim Jong Un has hailed the Choe Hyon as a milestone in his campaign to build a more formidable and versatile navy, capable of projecting power far beyond the country’s shores. State media have trumpeted the destroyer’s ability to carry nuclear-capable missiles as a game-changer for the regime’s deterrence posture. And with performance tests scheduled for October and the prospect of a third destroyer joining the fleet, North Korea’s naval ambitions are moving from blueprint to reality.
As the Ulchi Freedom Shield drills continue, the eyes of the region—and the world—remain fixed on the Korean Peninsula. The coming months will reveal whether Kim’s threats and military displays are mere posturing or harbingers of a more dangerous era of confrontation. For now, the launch of the Choe Hyon and the escalation in rhetoric serve as stark reminders that peace in Northeast Asia remains as elusive as ever.
