Unmanned surface vehicles are boats that operate on the surface of the water without a crew.

The ASW Continuous Trail Unmanned Vessel (ACTUV) is a DARPA funded project launched in early 2010 to develop an anti-submarine drone. ASW is an acronym for Anti-Submarine Warfare. In January 2018 after successful sea trials it was announced that the "Sea Hunter" prototype has transitioned from DARPA to the Office of Naval Research for further development.

Buffalo Automation is an artificial intelligence (AI) startup that develops autonomous navigation technology for commercial ships, recreational boats, and water taxis with the goal to improve maritime safety.

The Fleet-class unmanned surface vessel, also called the Common Unmanned Surface Vessel (CUSV) and later the Mine Countermeasures Unmanned Surface Vehicle, is an unmanned surface vessel designed for the United States Navy to be deployed from Freedom and Independence-class littoral combat ships and intended to conduct mine and anti-submarine warfare missions. As of 2012 four units of the class have been built; the first was delivered to the U.S. Navy in 2008.

The Protector unmanned surface vehicle (USV) was developed by the Israeli Rafael Advanced Defense Systems in response to emerging terrorist threats against maritime assets such as the USS Cole bombing, and is the first operational combat USV in service. It is fitted with a Mini Typhoon Weapon Station. In 2005, it was deployed by the Singapore Navy to support coalition forces in the Sea of Japan, and was later deployed for anti-piracy duties in the Gulf of Aden. In 2012, Rafael announced that they were building a larger version of the Protector, that would have a greater range, and be equipped with a wider range of weaponry.

Sea Hunter is an autonomous unmanned surface vehicle (USV) launched in 2016 as part of the DARPA Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) program. She was christened 7 April 2016 in Portland, Oregon. She was built by Vigor Industrial. The vessel continues the line of experimental "Sea" ships, including Sea Shadow, Sea Fighter, Sea Jet, and Sea Slice. Sea Hunter is classified as a Class III USV and designated the Medium Displacement Unmanned Surface Vehicle (MDUSV).

UAPS20 is an autopilot system that installed on an RHIB boat to obtain a low-cost unmanned surface vehicle.
