NEW YORK (Reuters) — The United States has deployed uncrewed drone speedboats for patrols as part of its operations against Iran, the Pentagon said, the first time Washington has confirmed using such vessels in an active conflict.

The deployment of the vessels — which can be used for surveillance or kamikaze strikes — has not been previously reported. It comes despite a series of setbacks in the US Navy’s years‑long effort to field a fleet of uncrewed surface vessels, Reuters reported last year.

Uncrewed vessels have risen to prominence in recent years after Ukraine used explosive‑laden speedboats to inflict significant damage on Russia’s Black Sea Fleet.

Iran has used sea drones to attack oil tankers in the Gulf at least twice since the US and Israel began strikes nearly a month ago, to degrade the Iranian regime’s military capabilities and distance threats posed by Iran, including its nuclear and ballistic missile programs.

There was no indication that the US had used uncrewed vessels for offensive strikes.

In response to Reuters’ questions, Tim Hawkins, a Pentagon spokesperson for Central Command, said unmanned vessels built by Maryland-based BlackSea, known as the Global Autonomous Reconnaissance Craft, or GARC, had been used for patrols as part of the US-Israeli campaign against Iran, dubbed Operation Epic Fury by Washington, and Operation Roaring Lion by Israel.

“US forces continue to employ unmanned systems in the Middle East region, including surface drone assets like the GARC. This platform, in particular, has successfully logged over 450 underway hours and more than 2,200 nautical miles during maritime patrols in support of Operation Epic Fury,” Hawkins said in a statement.

Hawkins declined to name any of the other unmanned systems being deployed. BlackSea declined to comment for this story.

Navy struggles with drone boats

The US has for years been trying to build a fleet of autonomous uncrewed surface and underwater vessels, as a cheaper and faster alternative to manned ships and submarines, particularly to counter China’s growing naval power in the Pacific. The effort, however, has fallen behind schedule and been dogged by technical problems, cost concerns and a series of testing setbacks.

Last year, Reuters reported the GARC, an angular speedboat about five meters long, was involved in multiple performance and safety issues, including one where it collided with another boat at speed during a military test.

In recent weeks, during another failed test in the Middle East, one GARC boat became inoperable, according to a source who was briefed on the matter.

Hawkins declined to comment on the testing setbacks.

“The GARC is an emerging capability and part of a fleet of surface drones operated by US 5th Fleet to enhance awareness of what’s happening in regional waters,” he said.
