WASHINGTON – US used sea drones in combat for the first time, deploying unmanned boats in a strike on Iranian naval facility, brining autonomous vessels to play roles once reserved for traditional warships.
For the first time, US armed forces deployed sea drones in a real combat operation, using autonomous attack boats to strike an Iranian naval facility at Bandar Abbas. US Central Command (CENTCOM) said three Saronic Corsair unmanned surface vessels (USVs) carried out coordinated strikes on a submarine and ship maintenance facility that Washington said was linked to attacks on commercial shipping.
The operation marked the combat debut of American sea drones and signaled a major shift in how future naval battles may be fought.

Sea drones, aka Unmanned Surface Vehicles (USVs), are robotic boats that can operate without a crew onboard. Depending on the mission, they can be remotely controlled by human operators or navigate autonomously using artificial intelligence, GPS, radar, cameras, and onboard sensors.
These vessels range from compact speedboat-sized platforms to large ocean-going ships capable of remaining at sea for weeks or even months.

From a newly unveiled prototype to personnel recovery and its first acknowledged combat mission, the Saronic Corsair has rapidly emerged as one of the most important unmanned vessels in the U.S. military’s future… https://t.co/NdyG4YIwdo pic.twitter.com/hdALcj7kH6

Unlike traditional warships, sea drones eliminate the need to place sailors in dangerous environments while performing missions that include surveillance, intelligence gathering, mine detection, anti-submarine warfare, logistics, search-and-rescue, and increasingly, precision strike operations.
The platform used in the strike was the Saronic Corsair, a 24-foot autonomous attack boat developed for the U.S. military.
Despite being about the size of a large speedboat, the Corsair is designed for long-range operations. It can travel more than 1,150 nautical miles, carry payloads weighing up to 1,000 pounds, and operate in intelligence, surveillance, reconnaissance (ISR), and attack roles. During combat missions, it can function as a one-way explosive drone that destroys itself upon impact with the target.
CENTCOM said three Corsair drones struck Iran’s Bandar Abbas Naval Base in first combat use of American sea drones. US said the operation was intended to reduce Iran’s ability to threaten commercial shipping through the Strait of Hormuz, where attacks had increased insurance costs and forced many cargo vessels to reroute.
Instead of risking billion-dollar destroyers or placing sailors in harm’s way, commanders can deploy relatively inexpensive autonomous boats to carry out dangerous missions. Multiple sea drones can also attack simultaneously, making them difficult for enemy defenses to stop.
US is now adopting similar tactics, but with more advanced autonomous systems capable of operating alongside traditional naval forces. Corsair is operated by Task Force 59, a Bahrain-based U.S. Navy unit established in 2021 to integrate artificial intelligence and unmanned systems into maritime operations across the Middle East.
Task Force 59 combines aerial, underwater, and surface drones with conventional warships to improve maritime surveillance and security. Since its formation, it has accumulated tens of thousands of operational hours while testing more than 20 different autonomous systems.
Earlier this year, one of its Corsair vessels also helped rescue the crew of a downed U.S. Army helicopter—the first known personnel recovery mission involving an unmanned surface vessel.
Other programs include the Sea Hunter and Seahawk, long-endurance unmanned ships designed to track submarines, along with the Ghost Fleet (Overlord) program, which is developing larger autonomous vessels capable of carrying missile payloads and other modular weapons.
For the unversed, the long-term objective is ambitious by 2045, unmanned vessels are expected to make up a major portion of US surface fleet, allowing the Navy to operate more ships at lower cost while reducing risks to personnel. They are said to be cheaper than conventional warships, require no onboard crew, can remain deployed for extended periods, and can be produced in large numbers. Their ability to swarm targets also makes them particularly effective against larger naval vessels.
However, they are not without limitations. Electronic warfare, GPS jamming, communication disruptions, and autonomous navigation in contested environments remain major technical challenges.
