North Korea Says It Test-Fired an AI-Guided Torpedo Built to Hunt Southern Warships

North Korea has carried out an underwater test of a new torpedo system it calls Zam-2.0, state media reported, describing a weapon built around artificial intelligence that handles both locating its target and steering itself toward it.

The test itself took place on Thursday, with the North's state news agency KCNA disclosing the launch two days later, on Saturday. No location for the test was given, a common pattern in North Korean weapons announcements that makes independent verification difficult.

AI handles the hunting, not just the steering

According to the state media account, the artificial intelligence built into the torpedo is applied to both target detection and the guidance function, meaning the system is designed to identify a target on its own and then adjust its course to stay on it, rather than simply following a pre-programmed track. State media also framed the launch as validating what it called core technology for improving propulsion efficiency and the performance of the torpedo's rocket propulsion devices, claiming the program behind it has run more than 180 related tests over five years.

Unnamed senior defense officials were said to have overseen the test, with state media quoting an assessment that called it a great success foreseeing a significant change in the actual development of the North's navy. The report made no mention of leader Kim Jong Un attending personally, a notable absence given how often major weapons tests are staged around his presence.

A weapon aimed squarely at the South's surface fleet

Outside analysts reading the announcement focused less on the propaganda framing and more on what the weapon is apparently built to do. Lim Eul-chul described the torpedo as difficult to detect in advance and avoid, and said its evident purpose is to target the South Korean Navy's major surface ships, the kind of large, high-value vessels that form the backbone of the fleet.

Shin Jong-woo offered a similar reading, framing the test as part of a broader pattern in which North Korea is steadily narrowing the gap in naval capabilities with the South, an assessment that treats Zam-2.0 less as an isolated announcement than as one more data point in a longer-running undersea arms competition.

A claim still waiting on independent confirmation

As with most North Korean weapons disclosures, the details come entirely from state media, leaving the torpedo's actual range, speed and reliability unverified by outside sources. What is clear is the message North Korea wants delivered: that its navy is folding artificial intelligence into its weapons programs, and that the specific target in mind is the South's surface fleet.
