State media in North Korea published a report on Saturday stating that an underwater trial of a newly developed torpedo system — one incorporating artificial intelligence to handle both target detection and directional guidance — had been carried out and deemed a success. A Thursday test-firing of the Zam-2.0 — described by its developers as a high-velocity, precision-guided system — was presented by the Korean Central News Agency as marking a shift in naval capabilities, though the state outlet did not elaborate on how artificial intelligence factors into the weapon's operation.
According to that outlet's coverage, the assessment served as a concluding check on whether the weapon's drive mechanisms could sustain operational demands, drawing on a body of more than 180 trials conducted across the preceding five years. State media reported that defence officials overseeing the trial concluded it had validated core advances in propulsion efficiency and rocket-drive performance, with the findings pointing toward a shift in how the navy's capabilities are expected to develop.
No statement from the armed forces came in response to the report, despite their history of contesting Pyongyang's assertions about weapons and technology development.
Pyongyang's naval posture has grown more assertive over recent weeks — with underwater missile launches conducted for the first time in close to three years — as Kim Jong Un redirects the country's defence focus toward maritime domains following a prolonged period of ballistic missile activity. Lim Eul-chul, a researcher at Kyungnam University's Institute for Far Eastern Studies, told a news outlet that the exercise appeared intended to demonstrate an AI-guided torpedo with high-speed capability, a weapon built for low detectability and evasion difficulty, and one positioned to pose a threat to surface vessels operated by the South Korean Navy.
The weapons tests are thought to have involved an as-yet-undeployed submarine that the North Korean government has described as capable of carrying nuclear warheads. Some analysts have put forward the view that the device undergoing testing fits the profile of a supercavitating torpedo. According to broadcast reports, the weapon works by generating an air cavity at its nose to reduce drag from water, allowing it to reach velocities beyond those of standard underwater munitions.
A statement from Kim Yo Jong, the sister of North Korean leader Kim Jong Un, described a test of an intermediate-range hypersonic missile capable of reaching multiple distances, with artificial intelligence playing a role in the launch process. A number of specialists in the field have raised reservations about the accuracy of the country's assertions on advanced weaponry. Engineering teams in other nations have run into documented obstacles when attempting to steer and stabilise torpedoes of this class once they reach extreme underwater velocities.
Talks about a potential face-to-face meeting between Trump and the North Korean leader at next month's Asia Pacific Economic Cooperation gathering in China form part of the broader context surrounding these developments. During his scheduled November tour of Asia, Trump raised the possibility of a face-to-face meeting with the North Korean leader. Diplomatic gestures from Trump intended to revive the negotiations that broke down in 2019 have drawn pushback from Kim.
The administration put forward a position that any dialogue with Pyongyang should not be contingent on denuclearisation, and that what it characterised as a confrontational American stance toward North Korea should be set aside before negotiations could begin. Pyongyang severed all ties and joint programmes with Seoul, characterising its southern neighbour as a permanent adversary, even as nuclear talks between North Korea and Washington have remained at an impasse for years.
