e/Unmanned surface vehicle

Information
has gloss	eng: The term unmanned surface vehicle (USV) refers to any vehicle that operates on the surface of the water without a crew. USVs have been tested since World War II but have been largely overshadowed. This is due to the fact the USVs, such as the OWL Mk II surveillance drone, have been classified as Autonomous Underwater Vehicles. Recent successes of UAVs in the Afghan War may pave the way for a new wave of USVs.
