Piranha Unmanned Surface Vessel
The Piranha Unmanned Surface Vessel (USV or unmanned surface vehicle) is a watercraft developed by Zyvex Marine (a division of Zyvex Technologies, formerly Zyvex Performance Materials) in 2010. The boat is  in length and weighs just . The Piranha is the first USV to utilize a lightweight carbon-nanotube enhanced composite material called Arovex, which allows the watercraft to weigh "significantly less" than any other USV. The weight advantage from Arovex gives the Piranha a payload capacity of  and a range of over . Additionally, the carbon nanotubes provide a strength increase of 20–50% over traditional materials. With those characteristics, the Piranha is expected to be sold as a possible tool for anti-piracy, search and rescue, submarine hunting, and harbor patrol. The first Piranha began construction in February 2010 with an anticipated completion date of summer 2010. The Piranha underwent sea trials near Seattle's Puget Sound during the months of October and November 2010. The Piranha concluded approximately 6 months and  of sea trials in Washington state and Oregon state on April 4, 2011. References
