The Fincantieri Marinette Marine (FMM) shipyard of the Fincantieri Marine Group, the American subsidiary of the Italian group Fincantieri will build Spectre naval drones in aluminum designed by the American Saildrone. Autonomous naval vessels, weighing 250 tons, they will be 52 meters long and will have a maximum speed of 30 knots. The drone will be specialized in anti-submarine warfare operations, but will be able to also carry out other types of attacks. Spectre will have a range of 3,280 nautical miles in calm waters and 2,790 nautical miles nautical miles with very rough seas at the bow. In addition, the drone will have a concealed cargo deck that will provide space for cargo containerized, from two containers from 40 feet up to five 20-foot containers, or a combination of configurations with a maximum load capacity of over 70 tons.

The construction of the drones will begin soon and is expected that the first will undergo sea trials at the beginning of the next year. The FMM shipyard has a capacity of production of five Spectres per year.
