U.S. Central Command used three Corsair unmanned surface vessels to strike a submarine and ship-maintenance facility on the Iranian coast over the weekend, the first documented combat use of one-way attack sea drones by the U.S. military, according to Defense News and Breaking Defense, citing CENTCOM. The command released video showing the vessels approaching docks and detonating.
What We Know
CENTCOM confirmed the strike involved three Corsair one-way attack unmanned surface vessels targeting a submarine and ship-maintenance facility, per Defense News. The command posted footage showing the drones closing on port infrastructure before detonating on impact, according to Breaking Defense.
The Hill reported the assault occurred Sunday and was carried out against an Iranian port. Task & Purpose characterized the operation as the U.S. military’s first combat use of the vessel class in any theater. CENTCOM described the wider weekend campaign as hitting “dozens” of Iranian targets with precision munitions.
The Corsair is a one-way attack unmanned surface vessel — the sea equivalent of a loitering munition or one-way attack drone — designed to close on a target and detonate rather than return.
What We Don’t Know
CENTCOM has not publicly named the port or the specific facility struck, nor has it released a formal battle-damage assessment. Which Iranian submarine class or ships were at the maintenance facility at the time of the strike has not been disclosed. The manufacturer of the Corsair USVs used in the operation, unit cost, and how many are in the U.S. inventory have not been detailed on the record. Iran has not publicly acknowledged the specific sea-drone strike as of this filing. This story is developing.
Context
The confirmed combat debut of a U.S. sea drone is a materially distinct operational milestone from the running exchange of missile strikes and casualty counts. It signals that the same one-way attack drone doctrine the U.S. and its adversaries have refined in the air and land domains has now been operationalized at sea — and it was done against Iranian port infrastructure, not open-water shipping.
The strike is part of the wider Monday-window U.S. campaign that also included strikes on the oil-refining city of Abadan and a broader wave of Monday attacks against Iranian air defense and coastal radar. Iran has responded by claiming retaliatory strikes on U.S. military sites in Bahrain, Kuwait, and Oman, following Saturday’s U.S. attacks on Iranian missile systems near the Strait of Hormuz.
What to Watch
- Whether CENTCOM releases the specific port location, target list, and battle-damage assessment for the Corsair strike.
- Whether Iran’s naval command publicly acknowledges the loss of the submarine and ship-maintenance facility, and how it characterizes the sea-drone threat going forward.
- Whether the Corsair debut prompts additional U.S. USV deployments to the Fifth Fleet area of responsibility, or accelerated procurement in the FY27 defense budget cycle.
This is a developing story. Updates will follow as CENTCOM releases additional details.
