'Hormuz Is Our Hunting Ground': Iran Claims Seizure of Second US Underwater Drone
In a dramatic assertion escalating maritime frictions in the Persian Gulf, Iran's Islamic Revolutionary Guard Corps (IRGC) announced on Monday, September 28, 2026, that its naval forces had intercepted and seized a second United States military unmanned underwater vehicle (UUV) operating within the Strait of Hormuz. Revising earlier official briefings that initially designated the captured submersible as a REMUS 600 system, Iranian defense officials identified the high-tech autonomous craft as an advanced Mk 18 Mod 2 Kingfish. Labeling the strategic chokepoint an active "hunting ground" for the IRGC Navy against American undersea assets, Tehran proclaimed the capture as a major intelligence and technological coup, asserting that specialized cyber and electronic warfare units successfully trapped the surveillance craft during a clandestine reconnaissance mission.
High-Value Military Hardware: IRGC Declares Mk 18 Kingfish a 'Trophy of Intelligence'
Announcing the operational interception on social media platform X, senior IRGC leadership celebrated the maritime capture:
Confirmation by IRGC Command: IRGC spokesperson Second Brigadier General Hossein Mohebbi formally confirmed the operation, declaring that the vital waterways of Hormuz have become an impenetrable trap for American unmanned underwater assets.
Technological Sophistication: Describing the seized asset, General Mohebbi remarked, "Our second victim, this time a Mk 18 Mod 2 Kingfish, has been captured. This is an advanced, autonomous AUV equipped with sonar and precision navigation, worth millions of dollars. This is not just a prey, but a major trophy of technology and intelligence."
From REMUS 600 to Kingfish: While the naval command initially misidentified the vehicle as a REMUS 600 civilian-derivative platform, technical audits by Iranian naval engineers led them to reclassify it as the specialized Mk 18 Mod 2 Kingfish—a variant utilized by naval forces for mine countermeasures, hydrographic reconnaissance, and covert bathymetric mapping.
Electronic Warfare and Data Extraction: Submersible Handed to Cyber Experts
Iranian state media reported that the operation relied heavily on coordinated technical interdiction rather than kinetic fire:
Electronic Trapping Maneuver: According to state broadcaster Islamic Republic of Iran Broadcasting (IRIB), the IRGC Navy coordinated with military signals intelligence and electronic warfare battalions to jam, intercept, and recover the US underwater drone while it conducted purported espionage operations along designated maritime lanes.
Extraction of Classified Telemetry: IRIB stated that the recovered submersible system has been transferred to specialized defense research laboratories and electronic warfare specialists to reverse-engineer its components and decode recorded acoustic maps, route waypoints, and stored digital surveillance files.
Lack of Independent Verification: Despite elaborate operational descriptions broadcast across state television, Iranian authorities have not presented independent international observers or conclusive physical chain-of-custody verification detailing the exact time and GPS coordinates of the seizure.
Hardline Warning on Strait of Hormuz: Strict Action Against Unauthorized Maritime Movement
The incident has triggered renewed warnings from Tehran over navigation rights across the world's most critical crude oil transit passage:
Strategic Energy Chokepoint: Through the Strait of Hormuz flows approximately one-fifth of the world's total petroleum consumption, making any hostile encounter between Iranian coastal units and US Fifth Fleet assets an immediate threat to global energy security.
Vow of Sustained Interdiction: Reaffirming its hardline naval doctrine, the IRGC Command issued an uncompromising alert stating that Iranian naval patrols will maintain round-the-clock vigilance and initiate decisive countermeasures against any unauthorized, clandestine, or suspicious military movements traversing the waterway.
