   US Navy Tests Robotic Refueling for Unmanned Surface Vessels

   The US Navy successfully demonstrated an unmanned refueling at sea process off the coast of Virginia using a robotic towed connector. A 38-foot drone boat, which previously completed a 192-hour solo voyage, connected to a float towed by a Navy ship. Over dozens of hookups, the drone boat took on 400 gallons of fuel. The operation involved a remote operator steering the probe during the process. This demonstration confirms the technical feasibility of replenishing autonomous vessels without direct human intervention on the receiving craft.

   Why it matters

   Maintaining an autonomous fleet requires solving the logistics of fuel and power replenishment at sea. This robotic connector addresses a critical gap in unmanned operations by removing the need for manual docking. The Naval Warfare Center led the showcase to improve the endurance of unmanned surface vessels.

   What is confirmed

   • The US Navy demonstrated unmanned surface vessel refueling at sea using a robotic towed connector.
   • The tests took place off the coast of Virginia.
   • A 38-foot drone boat was used in the refueling demonstration.
   • The drone boat took on 400 gallons of fuel over dozens of hookups.
   • The refueling process utilized a float towed by a Navy ship.

   Still unconfirmed

   • The 38-foot drone boat previously spent 192 hours alone at sea.
   • A remote operator steered the fuel probe during the hookups.
   • The process involved 100 trials.

   What to watch next

   • Integration of the robotic connector into standard Navy autonomous fleet operations
   • Results from expanded trials with larger unmanned surface vessels
   • Details on the level of autonomy achieved versus remote steering requirements
