North Korean leader Kim Jong Un presided over the commissioning of his navy's second nuclear-capable destroyer on Sunday, declaring the warship capable of delivering "annihilating retaliatory strikes on an enemy" just as the United States, South Korea and Japan launched a major joint naval exercise off the Korean peninsula.

The ceremony for the 5,000-ton destroyer Kang Kon took place at Wonsan port on North Korea's east coast, with Kim attended by his daughter, Kim Ju Ae, and senior military officials, according to state media KCNA and a report from Al Jazeera. "The time has come for us to exercise our sovereignty at sea and under water," Kim said, adding the ship "represents the self-respect and will" of North Korea to defend its interests.

The Kang Kon is the second of North Korea's Choe Hyon-class guided-missile destroyers, sister ship to the Choe Hyon commissioned in June. Naval analysts say the class carries 88 vertical launch cells across five missile configurations, some reportedly capable of carrying nuclear warheads, alongside advanced phased-array radar systems, according to Naval News.

Getting the Kang Kon to sea took an embarrassing detour: the vessel partially capsized during its first launch attempt at the Chongjin shipyard in May 2025, an incident Kim publicly called a "criminal act" at the time. Workers righted and repaired the ship, which was relaunched weeks later, underwent additional sea trials, and finished weapons testing this past July before Sunday's commissioning — more than a year after its rocky debut.

Drills Meet Deterrent

The commissioning landed squarely on top of "Freedom Edge," a five-day trilateral military exercise that the U.S., South Korea and Japan kicked off Monday in waters east and south of South Korea's Jeju Island. The drill, running since 2024, is billed by Seoul's Joint Chiefs of Staff as a defensive exercise meant to sharpen missile-defense coordination and antisubmarine warfare against North Korean threats; participants include South Korean and Japanese Aegis destroyers and the U.S. 7th Fleet's USS Benfold, per UPI.

Pyongyang did not let the timing pass quietly. North Korea's newly installed defense minister, Kim Song-gi, issued his first public statement since taking the post on August 29, branding the drills a provocation and warning the North would take "strong and reflective countermeasures from the standpoint of power" if the U.S. and its allies sought a "new military confrontation," the Jerusalem Post reported. State media quoted his ministry describing the U.S.-Japan-South Korea security partnership as being "transformed into a dangerous offensive entity accompanied by nuclear elements."

What's Next

The back-to-back destroyer commissionings are part of a broader naval buildup Kim has championed as North Korea leans harder into its self-declared, "irreversible" status as a nuclear weapons state — an ambition that has deepened alongside Pyongyang's growing military cooperation with Moscow amid the war in Ukraine. Kim has signaled more warships are coming, framing a nuclear-armed navy as insurance against what he calls constant threats from Washington and Seoul.

For now, neither the Pentagon nor South Korea's military has issued a direct public response to Sunday's ceremony, and Freedom Edge is proceeding on schedule through the week. But with a new destroyer promising "retaliatory strikes" now sailing North Korean waters and a freshly appointed defense minister already talking tough, the coming days of joint drills are likely to keep the temperature rising on one of the world's most heavily armed borders.
