North Korea says it has launched two types of strategic cruise missiles from a submarine in the East Sea, displaying a harder-to-track method of delivering weapons from below the surface. The launches took place on October 14 and were reported by state media the following day, according to South Korean news reports citing the North's announcement.

Images released after the launch showed one missile rising through heavy spray while another appeared to leave at an angle with a column of smoke. Based on the visible submarine, MBC reported that the vessel was believed to be the roughly 3,000-ton Kim Kun Ok Hero, which North Korea presented in 2023 as its first tactical nuclear attack submarine. Its participation has not been independently confirmed in the supplied reports.
An undersea platform returns to public view
The appearance of two different launch profiles supports North Korea's effort to demonstrate that a single undersea platform can fire different weapons in more than one direction. The latest activity also marks the first reported public operation of the submarine since its launch ceremony three years ago, giving the images significance beyond the immediate missile launches.
Submarine-launched cruise missiles create a different surveillance problem from weapons fired at established land sites. A submarine can move before launching, reducing the warning available from monitoring known positions. Cruise missiles can also fly at low altitude and follow less predictable routes, complicating efforts to detect and track them after launch.
The launches add to a burst of North Korean missile activity during October. MBC reported that Pyongyang had already fired several ballistic missiles, including hypersonic weapons, before disclosing the submarine exercise. It was also North Korea's first reported submarine missile launch since March 2023.
Operational capability remains unverified
North Korea has repeatedly framed the submarine as part of a nuclear strike force. At the vessel's 2023 launch ceremony, Kim Jong Un said a nuclear attack submarine would become a threatening symbol of power capable of terrifying the country's enemies. The latest disclosure reinforces that political message, although the supplied evidence does not establish the missiles' range, flight path, accuracy, warhead configuration or operational readiness.
For South Korea, the practical concern is the possibility of having to monitor both land-based launch areas and mobile undersea platforms. The combination of concealment at sea and low-altitude cruise missile flight could place additional demands on maritime surveillance, early warning and air defense. The reports do not provide enough information to determine whether the submarine and missiles can yet conduct sustained operational patrols.
The next evidence to watch will be any official release of flight data, launch location details or signs that the submarine has begun regular deployments. Further tests involving repeated launches, longer periods at sea or additional missile types would provide a clearer measure of whether North Korea is moving from a staged demonstration toward a dependable operational capability.
