North Korea has test-fired a new high-speed precision-guided torpedo equipped with artificial intelligence technology, according to state media, in what Pyongyang hailed as a major breakthrough for its navy.
The underwater test of the new "Zam-2.0" torpedo took place on Thursday, state media Korean Central News Agency (KCNA) reported on Saturday without releasing images of the weapon. The report was picked up by NK News and widely echoed by international outlets including the Associated Press, Euronews, The Japan Times and the South China Morning Post.

How the Test Was Announced
The reporting chain is as notable as the claim itself. The test was disclosed exclusively through KCNA, North Korea's official state wire, which published the announcement on Saturday — two days after the test itself. NK News, a specialist outlet that monitors North Korean state media, translated and reported the details, and the story was then carried by the Associated Press, ABC News, Euronews, The Japan Times, Nikkei Asia, The Hindu and TRT World, among others, within hours.
That rapid international pickup reflects a simple reality: every North Korean weapons announcement is scrutinized for signals about the country's advancing capabilities, and AI is currently the most watched technology in military circles worldwide.
What State Media Claimed
According to KCNA, the test was carried out by the Academy of Defence Science, the Missile Administration and the Torpedo Weapons Research Bureau to "confirm successful technical updating of a new-type torpedo weapon system."
State media claimed the weapon incorporates AI technology into its target detection and guidance systems — language that positions the Zam-2.0 as an autonomous or semi-autonomous underwater weapon rather than a conventionally guided torpedo. As with most North Korean weapons claims, no independent verification was offered, and state media released no images of the test itself.
An Evolving Underwater Program
The Zam-2.0 is the latest in a line of underwater vehicles Pyongyang has publicized. NK News noted that state television previously showed an image of the Haeil-2 unmanned underwater vehicle, reportedly during tests in April 2023, indicating that torpedo and underwater drone development has been an area of sustained investment rather than a one-off announcement.
The description of the new weapon as "high-speed" and "precision-guided," combined with AI-assisted target detection, suggests Pyongyang is prioritizing the same attributes — range, speed, and resistance to countermeasures — that navies around the world are pursuing as underwater autonomy matures.
A Flurry of Weapons Tests
The test comes amid a flurry of missile launches from Pyongyang in recent weeks, as NK News noted in its report. The timing gives the torpedo test added visibility: each launch lands in the middle of an already tense stretch on the Korean peninsula, and each new capability claim feeds into regional defense planning in Seoul and Tokyo.
It also lands weeks before the US midterm elections and during a period of heightened attention to military applications of AI generally — from autonomous drones to AI-assisted targeting — which guarantees the story a wide international audience despite the thin sourcing.
Why Military AI Claims Are Hard to Verify
Outside verification of North Korean weapons claims is limited, and the details that separate a genuine capability from a propaganda claim — the actual autonomy of the guidance system, its performance against moving targets, its reliability — are exactly the details state media did not provide. The absence of images from this test, unlike the 2023 Haeil-2 broadcast, makes independent technical assessment even harder.
What can be said with confidence is what was reported: a test occurred, KCNA attributed AI capabilities to the weapon's target detection and guidance systems, and the state's weapons-development bureaucracy — from the Academy of Defence Science to a dedicated Torpedo Weapons Research Bureau — is organized around this program. That a country under heavy sanctions is publicly claiming AI-guided naval weapons says as much about its ambitions as any single test does.
Target detection and guidance are precisely the components where AI changes a torpedo's character. A conventional precision torpedo follows pre-set search patterns against signatures its designers anticipated; an AI-assisted system, as claimed here, would in principle classify and track targets in changing conditions without further input. The KCNA description stops well short of detailing how much autonomy the Zam-2.0 actually has — and that gap between claim and specification is where any assessment has to stop.
The Broader Pattern
The Zam-2.0 test fits a global pattern that defense analysts have tracked for several years: major and minor military powers alike are racing to add AI to guidance, targeting, and autonomy stacks across land, air, and sea systems. North Korea's version of that race is conducted under sanctions and secrecy, announced through state media, and demonstrated through tests rather than exports or papers.
For now, the Zam-2.0 remains a claim rather than a verified capability. But as underwater autonomy spreads, the test is another data point in how quickly AI-assisted weapons are moving from research programs to advertised arsenals.
