The US Navy has successfully resupplied one of its submarines using a commercial drone.
A small, four-rotor UAV was used to resupply the USS Hawaii, according to a report by Forbes.
The resupply mission took place just a mile off the coast of Oahu, Hawaii and saw the drone deliver a payload of circuit cards, medical supplies and food.
Future missions could see the drones equipped to deliver a range of payloads from medical supplies to replacement parts.
Using UAVs over larger, manned helicopters presents a range of benefits including cost-saving, pilot safety and freeing up helicopters for larger missions.
With drone delivery still in its early stages, the US Navy is far away from being able to deliver large payloads to submarines out on missions for several months.
However, as drone delivery technology improves and the further military applications of UAVs becomes known, the future is starting to seem a lot closer.
