At a ceremony on the western port of Nampo on Tuesday, Kim Jong Un watched the 5,000-ton destroyer Choe Hyon formally enter service with the North Korean navy. State media portrayed the moment as a watershed: not merely the addition of a warship, but the visible proof, in Kim's telling, that his programme to arm his navy with nuclear weapons is advancing on schedule. For a country whose fleet has long been regarded as a coastal defence force, the symbolism was deliberate and pointed. The Choe Hyon is, according to Pyongyang's Korean Central News Agency, equipped with anti-aircraft and anti-ship weapons alongside ballistic and cruise missiles described as nuclear-capable.

North Korea has put the vessel through a series of tests in recent months, including what it claimed were nuclear-capable cruise-missile launches from the ship itself. South Korean officials and several independent analysts believe the destroyer was assembled with Russian technical assistance, a suggestion that sits within a broader pattern of deepening military cooperation between Moscow and Pyongyang — though some experts have questioned whether the ship is genuinely ready for sustained operational use. The commissioning fits a strategic shift that Kim has been signalling for some time. Having spent years directing resources towards ballistic-missile development, he has increasingly turned his attention to naval power.

At February's Workers' Party congress, he outlined five-year military goals that included intercontinental ballistic missiles capable of being launched from underwater platforms — an ambition that, if realised, would complicate defence calculations across the Indo-Pacific and beyond.
