U.S. Central Command launched three one-way sea drones on July 13, 2026, to strike an Iranian submarine and ship-maintenance facility [1], [2].
This operation marks a significant shift in naval warfare tactics, introducing unmanned surface vessels into active combat to degrade Iranian naval capabilities during a period of heightened regional tensions [1], [2].
The strike targeted the Bandar Abbas Naval Base, located in the Hormuz region [1], [3]. According to U.S. Central Command, the mission utilized Corsair sea drones to hit the specific targets [1], [2].
"We have successfully employed three one‑way sea drones to strike a naval facility in Iran," a CENTCOM spokesperson said [1].
The U.S. military confirmed that the operation represents the first time the United States has used sea drones in combat [2]. The targets included both a submarine and a facility used for the maintenance of ships [2], [3].
Reports on the extent of the damage vary. Some accounts indicate the submarine was destroyed, while other reports state the vessel was struck without immediate confirmation of its total destruction [1].
"The drones hit a submarine and a ship‑maintenance facility at Bandar Abbas," a WION correspondent said [2].
“This marks the first time the United States has used sea drones in combat.”
The deployment of Corsair sea drones signals a transition toward autonomous maritime attrition warfare. By using one-way drones, the U.S. can project power and damage high-value assets like submarines without risking manned vessels in contested waters. This development likely forces regional adversaries to rethink their coastal defense strategies and surveillance capabilities in the Strait of Hormuz.
