Capture of U.S. Uncrewed Submarine in the Strait of Hormuz
On September 8, Iran’s Islamic Revolutionary Guard Corps (IRGC) announced that its naval forces seized a U.S. uncrewed submarine at the entrance to the Strait of Hormuz. The vessel was identified by Iranian state media as a Dive-LD, a large autonomous underwater vehicle built by California-based defense firm Anduril. A handout photograph dated September 7, 2026 shows the captured submersible. The IRGC described the capture as a “complex intelligence and operational action” carried out at dawn.
Background on Underwater Drone Use
The U.S. military has been expanding its fleet of unmanned naval systems to monitor vast ocean areas, gather intelligence, and track adversary vessels while reducing risk to personnel. Underwater drones such as the Dive-LD are intended for missions that include mine countermeasures, seabed mapping, intelligence gathering, and inspection of underwater infrastructure like cables and pipelines.
Official Statements
The IRGC’s navy statement asserted that the captured drone represented one of the most modern and intelligent unmanned submarines in the “terrorist American army.” A Pentagon spokesperson responded that the drone had malfunctioned more than a day earlier, was conducting a regional survey in support of ongoing operations, and was an older model that did not carry sensitive sonar or radar data. Anduril confirmed the loss of a Dive-LD unit but emphasized that the system is “attritable,” meaning it is designed to be expendable in hazardous environments.
Data & Statistics
- Dive-LD dimensions: 19 feet (5.8 meters) long.
- Endurance: up to 10 days without returning to base.
- Depth capability: reported as either 19,700 feet (? 6,000 meters) or 6,000 meters, depending on the source.
- Unit cost: cited as about $2 in one report and about US$2.5 million in another.
Conflicting Reports & Gaps
Sources differ on several technical details. The depth rating is given as 19,700 feet in one outlet and 6,000 meters in another, creating an inconsistency in performance specifications. Cost estimates also vary dramatically, with one article stating a price of $2 and another reporting US$2.5 million per unit. Additionally, while the IRGC claims the drone was a modern system, the Pentagon characterizes it as an older model lacking classified equipment. Reuters was unable to independently verify Iran’s capture claim, and Anduril did not respond to a request for comment in one report.
