Unmanned surface vehicles (USV) or autonomous surface vehicles (ASV) are vehicles that operate on the surface of the water (watercraft) without a crew.

USVs are valuable in oceanography, as they are more capable than moored or drifting weather buoys, but far cheaper than the equivalent weather ships and research vessels,[1] and more flexible than commercial-ship contributions. Wave gliders, in particular, harness wave energy for primary propulsion[2] and, with solar cells to power their electronics, have months of marine persistence[3] for both academic [4][5] and naval applications.[6][7]

Powered USVs are popular for use in hydrographic survey. Using a small USV in parallel to traditional survey vessels as a 'force-multiplier' can double survey coverage and reduce time on-site. This method was used for a survey carried out in the Bering Sea, off Alaska; the ASV Global 'C-Worker 5' autonomous surface vehicle (ASV) collected 2,275 nautical miles of survey, 44% of the project total. This was a first for the survey industry and resulted in a saving of 25 days at sea.[8]

Military applications for USVs include powered seaborne targets and minehunting. Operational USVs with offensive capability include the Israeli Protector USV.[9]

In the future, many unmanned cargo ships are expected to cross the waters.[10]
