WASHINGTON, June 9 (Reuters) – A U.S. Navy drone rescued two Army helicopter crew members after their helicopter was shot down in the Middle East, in ​what was believed to be the first known U.S. ‌use of an unmanned military vessel to recover personnel at sea.

The Navy identified the rescue craft as a Saronic Corsair, a 24-foot (7.3-metre) autonomous surface vessel. The drone is part of the Pentagon’s push to expand unmanned ‌vehicles ​alongside traditional assets.

Here are some key facts ⁠about U.S. sea drones:

• ⁠A new kind of naval unit: Task Force 59, created in 2021 and based in Bahrain, is the U.S. Navy’s first unit dedicated to unmanned systems. The task force began ​fielding the Corsairs in the Middle East in late March.

• Drones on and below the water: The U.S. deploys both ⁠unmanned surface vessels and underwater vehicles, ⁠giving commanders flexibility depending on needs. Many of ​the most advanced underwater systems remain highly secretive. Drones offer unique ​capabilities and reduce risk for American forces.

• From scouting ‌to striking: Sea drones are used for surveillance, mine detection and tracking enemy activity. Some are also being adapted for combat roles. They can be useful for both routine monitoring and ⁠high-risk missions.

• Cost and responsiveness advantages: The Pentagon is investing in autonomous vessels as a cost-effective way to expand reach and speed response ⁠to threats. The ‌Navy plans mass deployment including hundreds and ⁠potentially thousands of Corsairs. Sea drone technology is ​still ‌evolving and has faced technical and operational challenges.

• ​Combat potential ⁠proven elsewhere: While not a U.S. system, Ukraine’s use of sea drones against Russia has demonstrated their battlefield impact, including sinking warships and even downing a helicopter — an unprecedented feat for an unmanned vessel.
