IRGC Claims Capture of U.S. REMUS 600 Underwater Drone in the Strait of Hormuz
By Drooid · · How we work
Core Event
Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy announced that it had seized a U.S. REM 600 autonomous underwater vehicle (UUV) operating in the Strait of Hormuz. The IRGC described the operation as “coordinated intelligence and electronic warfare,” stating that the drone was conducting espionage and that Iranian specialists were now examining the vehicle to retrieve its data. The IRGC also reiterated that the Strait of Hormuz remains “closed” and warned of a response to any “unauthorized passage or dangerous movements” in the waterway.
Background & Context
The incident follows a series of maritime confrontations between Tehran and Washington in recent weeks. Earlier, the IRGC reported intercepting a different U.S. UUV—a Dive-LD built by Anduril—near the strait’s entrance. The Pentagon later acknowledged the loss of that submersible, characterizing it as an older model that carried no classified equipment. The IRGC also claimed to have destroyed a U.S. Saildrone Explorer, while the U.S. military reported thwarting an IRGC attempt to seize another Saildrone. These exchanges occur against a backdrop of broader hostilities: the United States has destroyed several Iranian oil tankers after accusing the IRGC of firing ballistic missiles at U.S. warships, and Iran has targeted U.S. vessels and commercial tankers it alleges violate restrictions around the strait.
Data & Statistics
- Vehicle type: REM 600 UUV, used for surveillance, seabed mapping, mine countermeasures, and underwater inspections; operates to 600 m depth.
- Incidents this month: Two U.S. underwater drones reported captured (REM 600 and Dive-LD) and one Saildrone destroyed by the IRGC.
Official Statements & Responses
- IRGC Navy: Asserted that the REM 600 was seized during a coordinated operation and is now in Iranian hands for data extraction; reiterated that the Strait of Hormuz is closed and will be defended against “unauthorized traffic.”
- President Donald Trump: At a United Nations gathering, he rejected Iran’s seven-day proposal for reopening the strait and resuming nuclear talks, labeling it “unacceptable” and suggesting a “big decision” about potentially “annihilating” Iran if negotiations failed.
- Iranian Army Spokesperson Mohammad Akraminia: Warned that the United States could launch a renewed attack and that Iran is prepared to inflict greater damage on any U.S. aggression.
- Army Commander-in-Chief Major General Amir Hatami: Stated that Iran has won the initial phase of the conflict and will consolidate its victory while maintaining control over the strait.
Conflicting Reports & Gaps
The IRGC’s claim of a successful capture contrasts with CENTCOM’s denial that any U.S. operational drone assets have been compromised. No independent verification of the drone’s status has been provided, and the U.S. has not publicly responded beyond the CENTCOM statement. Details about the specific data stored on the REM 600 and the extent of any intelligence loss remain unconfirmed.
What’s Next
- United Nations proposal: Iran has offered a “concrete seven-day plan” to reopen the strait and resume nuclear negotiations contingent on the United States lifting its naval blockade, easing oil-export restrictions, releasing frozen assets, and observing a ceasefire that includes ending Israeli operations in Lebanon.
- U.S. response: President Trump has labeled the proposal unacceptable and indicated a willingness to consider “annihilating” Iran if talks fail.
- Operational posture: Both sides have signaled continued readiness for confrontation; the IRGC has pledged to intercept further “unauthorized” vessels, while the United States maintains that it retains control over its underwater drone fleet.
The unfolding situation highlights the fragile balance between strategic signaling and the risk of further escalation in one of the world’s most vital maritime corridors.
