The US Navy is testing robotic refueling to push drone boats deeper into high-threat waters without putting sailors at risk

The US Navy is testing whether it tin robotically refuel naval drones astatine sea, a capacity that could let them to run for longer successful higher-threat waters.

Uncrewed aboveground vessels whitethorn not request a crew, but they still request substance to operate. The caller trial is simply a measurement toward a afloat autonomous refueling process that Navy officials opportunity could yet fto the work nonstop uncrewed vessels into vulnerable waters for longer without quality support elements.

The Naval Air Warfare Center Weapons Division shared specifications Wednesday of a caller refueling objection involving the remotely controlled T38 USV built by Maritime Tactical Systems Inc. and a towable capture-and-connection robotic refueling strategy made by Sealartec.

During the testing successful the waters disconnected Joint Expeditionary Base Little Creek-Fort Story successful Virginia, the drone and the refueling strategy completed dozens of capture, refuel, and merchandise exercises. Four 100 gallons of substance were transferred to the T38.

The contiguous problem the Navy is trying to lick is tied to the Navy's testing of hypersonic and different long-range weapons. Those tests, "where formation profiles tin widen thousands of miles beyond fixed-range boundaries," tin "require data-collection assets to beryllium distributed crossed a immense area," Spencer Holloway, head of the division's Blue Water Instrumentation Future Capabilities Office, said successful a release.

Naval drones are useful for gathering that data, but having to return for substance cuts into their clip connected station. Holloway said that "every clip an unmanned alloy must return to larboard for fuel, we suffer persistence, trim sum and redundancy, and interrupt the mission."

The Navy sees a broader exertion arsenic well.

"This will let america to person greater reliance connected unmanned vessels alternatively of manned, and we tin push the USV into higher threat areas without risking parented vessels and personnel," Ronald Raymer, branch caput for capability, innovation, subject and exertion integration astatine US Fleet Forces Command, said successful the release.

"It will besides let america to administer greater capacity into an area without having to put successful ample costly parented vessels," he said.

The August objection was not afloat autonomous. The Navy's adjacent measurement is simply a complete end-to-end trial successful which a drone vessel tin meet up pinch a robotic refueling system, attack it, connect, return connected fuel, disconnect, and return to its ngo without usability power each measurement of the way.

To do that, Holloway said, the systems progressive will request much precise maneuvering and amended section positioning.
