Iran's Revolutionary Guard Navy says it has struck again beneath the waves, claiming to have captured a second American underwater vehicle in the Strait of Hormuz in less than a month. The IRGC identified the machine as a REMUS 600, an autonomous submersible used for seabed mapping, mine detection, and surveillance, and said it was seized through a coordinated intelligence and electronic warfare operation before being handed to specialists to extract its data. The claim follows an earlier announcement from September 8, when Iran said it had captured a similar US system, an Anduril Dive-LD, near the entrance to the same waterway. If accurate, back-to-back captures would hand Tehran a rare opportunity to study cutting-edge American underwater technology up close, potentially strengthening its own capabilities for years to come.

As of this report, neither US Central Command nor the Department of Defense had publicly confirmed or denied the latest REMUS 600 claim, and Washington had likewise stayed silent on the earlier Dive-LD incident. The lack of an official US response leaves the story resting almost entirely on Iranian state media accounts, which cannot be independently verified. It comes amid a tense standoff over the Strait of Hormuz, a critical corridor for global oil shipments, which Iran has declared closed and vowed to defend against what it calls unauthorized passage. Tensions in the region remain high following a bruising 2026 war between Iran, Israel, and the United States, with Washington maintaining a naval blockade and Tehran pushing back on multiple fronts, on the water and in the information space alike.
