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. The Piranha was 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.
