Piranha Unmanned Surface Vessel Explained

The Piranha Unmanned Surface Vessel (USV or unmanned surface vehicle) is a watercraft developed by Zyvex Marine (a division of Zyvex Technologies) in 2010. The boat is in length and weighs about 3600kg (7,900lb). The Piranha utilizes a lightweight carbon-nanotube material called Arovex, which allows the watercraft to weigh less than other USVs.[1] [2]

The weight advantage from Arovex gives the Piranha a payload capacity of 6800kg (15,000lb) and a range of over . Additionally, the carbon nanotubes provide a strength increase of 20–50% over traditional materials.[3] The Piranha was expected to be sold as a possible tool for anti-piracy, search and rescue, submarine hunting, and harbor patrol.[4]

The first Piranha began construction in February 2010 with an anticipated completion date of summer 2010.[5] The Piranha underwent sea trials near Seattle's Puget Sound during the months of October and November 2010. [6]

The Piranha concluded approximately 6 months and 600nmi of sea trials in Washington state and Oregon state on April 4, 2011.[7]
