A new and unusual incident has entered the Hormuz record: Iran says it has taken a United States underwater drone.

The IRGC Navy said its forces "trapped" one of the most modern American uncrewed submarines at the entrance to the strait at dawn on Tuesday, in what it called a complex intelligence-led operation [1]. Iranian state media identified the vehicle as a Dive-LD, a 5.8-metre autonomous submersible built by the Californian defence firm Anduril and delivered to the US military in 2025 [1][2]. Anduril says the type is used for mine countermeasures, seabed mapping, intelligence gathering and inspection of underwater infrastructure such as cables and pipelines [2]. The IRGC put its endurance at up to ten days and its depth rating at 6,000 metres [1].

Washington tells a different story. CENTCOM spokesperson Captain Tim Hawkins told NewsNation that the drone "malfunctioned more than a day ago" while surveying regional waters in support of ongoing operations, and said it was an older model carrying no sensitive data and no classified sonar or radar equipment [1]. A Pentagon spokesperson gave the same account, adding that US operations in area waters continue [2]. Anduril confirmed it had lost one of its vessels while playing down the significance, describing Dive-LD as an attritable system "designed from the outset to operate in dangerous environments where loss of the vehicle is an expected possibility" [2].

Both accounts agree on one fact: the vehicle is now in Iranian hands. They disagree on whether that resulted from an Iranian operation or a mechanical failure, and nothing retrieved so far resolves it. Iran has released images through state media [1][2].

For fuel, the interest is in what the drone was doing. A platform tasked with mine countermeasures and seabed survey operating at the strait entrance points to continuing concern about mines and about the condition of the transit lanes, at a time when a US naval blockade on Iranian ports remains in effect and Tehran still requires commercial vessels to seek authorisation to pass [1]. This is not evidence of a change in oil movement, and no shipping or flow figures were published alongside the claim. It is a military-intelligence episode at the mouth of the world's most important oil chokepoint, and the two sides' explanations remain irreconcilable.
