Iran's Revolutionary Guards said on Tuesday it had captured a U.S. uncrewed submarine at the entrance to the Strait of Hormuz, offering a rare glimpse into how underwater drones are being ​used in military operations, Reuters reported. 

Iranian state media said the vessel was a Dive-LD, a ​large autonomous underwater vehicle built by California defense firm Anduril.

The 19-foot (5.8-metre) ⁠submersible can carry out missions including mine countermeasures, seabed mapping, intelligence gathering and the ​inspection of underwater infrastructure such as cables and pipelines, the company has said.
