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 6,800 kg (15,000 lb) and a range of over 4,000 kilometres (2,500 mi).
[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.
