The United States has used unmanned surface vessels in combat for the first time, striking an Iranian naval base with three Corsair drones. CENTCOM confirmed the operation on Monday, calling it “the first time American forces have employed sea drones in combat operations.”
The Corsairs hit a submarine and ship maintenance facility at the Bandar Abbas naval base on the Strait of Hormuz. The strike was part of a broader wave of US attacks on dozens of Iranian military targets Sunday, the most significant escalation since Washington revoked Iran’s oil sale license on July 7, ending the ceasefire that began April 8.
The Corsair, built by Austin-based Saronic, is a 7.3-meter (24-foot) unmanned vessel with a range of over 1,850 km (1,000 nautical miles), a payload capacity of 450 kg (1,000 pounds), and a surge speed of 65 km/h (35 knots). Its “embedded AI stack and open architecture allow rapid integration of sensors and autonomy software,” Saronic says, making the platform adaptable for surveillance, logistics, and offensive operations.
The path to combat use was short. The Navy stood up Unmanned Task Group 59.1, called “The Pioneers,” in January 2024 under 5th Fleet’s Task Force 59, specifically to stress-test unmanned vessels in Middle Eastern waters. The Corsairs began fielding in late March.
In June, one of these drones rescued two Army Apache helicopter crew members who had crashed near the Strait of Hormuz, the first notable operational use. Now the same platform has shifted from rescue to strike.
Lt. Luis Echeverria, commanding officer of the Bahrain-based Pioneers, told Defense News the mission has evolved rapidly. Capt. Tim Hawkins, a CENTCOM spokesperson, confirmed the June rescue and the broader fielding of the Corsair system.
The shift from surveillance to offensive strike operations represents a quiet but significant change in how the Navy thinks about unmanned vessels. The Pioneers were set up to observe and understand the maritime environment, pattern-of-life monitoring, maritime domain awareness. Now they are hitting hardened targets at Iran’s primary naval base.
The war with Iran has already seen the first combat use of mass drone swarms, the first full-scale AI-assisted targeting campaign, and now the first combat deployment of sea drones. The technology has arrived. What happens next depends on who controls it, and who decides where to aim.
