The naval forces of Iran’s Islamic Revolutionary Guard Corps said on September 27 that they had captured an advanced US unmanned underwater vehicle in the Strait of Hormuz “through a coordinated, complex operation involving intelligence oversight and electronic warfare.” The IRGC identified it as a REMUS 600 autonomous underwater vehicle, saying it was “now in the hands of the force’s specialists for data recovery.”
The REMUS 600 is about 3.25 meters long and can dive to 600 meters for missions such as mine detection, seabed surveying and reconnaissance. IRGC sources released footage they said showed the vehicle after its capture.

It was the IRGC’s second such claim this month. Iran has blockaded the Strait of Hormuz since the conflict began in late February, while the United States has imposed a counter-blockade on Iranian ports. There was no immediate US response.
On September 8, the IRGC said it had seized another US underwater drone, an Anduril Dive-LD. CENTCOM spokesman Capt. Tim Hawkins confirmed the loss at the time, saying it was an older model that had malfunctioned and been dead in the water for more than a day, with no sensitive data aboard. The US Navy designates the REMUS 600 as the Mk 18 Mod 2 “Kingfish.”
