Iran claims to have captured a U.S. REMUS 600 underwater drone in the Strait of Hormuz.
According to the Iranian side, the unmanned underwater vehicle was carrying out a reconnaissance mission in the Strait of Hormuz, IRIB reported, citing a statement by the Islamic Revolutionary Guard Corps Navy. The IRGC said the underwater drone was captured during an operation involving intelligence-gathering capabilities and electronic warfare systems.
After being captured, the REMUS 600 was handed over to Iranian specialists. They are expected to examine the vehicle and attempt to recover information from its memory.
The Iranian side said that information of interest could include recorded routes, sonar data, navigation parameters, and other information that may have remained in the vehicle’s memory.
This is the second case in September in which Iran has claimed to have captured a U.S. unmanned underwater vehicle. On September 8, the IRGC Navy reported capturing another vehicle, an Anduril Dive-LD, near the entrance to the Strait of Hormuz.
The REMUS 600 is a U.S.-developed autonomous unmanned underwater vehicle designed for underwater reconnaissance, seafloor mapping, mine detection and classification, environmental data collection, and the search for underwater objects.
The vehicle can operate at depths of up to 600 meters. For autonomous navigation, it uses an inertial navigation system, a Doppler velocity log, and acoustic navigation, while GPS can be used when the vehicle surfaces.
According to the Woods Hole Oceanographic Institution, the REMUS 600 can operate for about 70 hours and has a range of up to 286 nautical miles.
