The Sparviero-class are small hydrofoil missile boats capable of traveling at speeds of 46 knots. They were designed for and formerly used by the Italian Navy. The Japanese 1-go class missile boat is an updated version formerly used by the Japan Maritime Self-Defense Force (JMSDF).
The Sparviero class fast attack hydrofoil was designed in Italy by the Alinavi society, a consortium of the American company Boeing, the Italian government's naval research branch, and Carlo Rodriguez, a Messina-based builder of commercial hydrofoils, based on Boeing's Tucumcari for the US Navy. A prototype, named Sparviero was ordered in 1970 for the Italian Navy,Sparviero was laid down by Alinavi in La Spezia in April 1971, was launched on 9 May 1973 and finally commissioned into Italian navy service on 15 July 1974.
The design used the Boeing Jetfoil system, with one hydrofoil forward and two aft, which folded out of the water when cruising. The ship was propelled at high speeds by a Rolls-Royce Proteus gas turbine driving a water jet, while a diesel engine driving a retractable propeller powered the ship at low speeds. The hull and superstructure were constructed entirely of aluminium. As the design was intended for short-range, high speed operations, no sleeping accommodation was fitted. Armament consisted of two Otomat anti-ship missiles aft and a single Oto Melara 76 mm rapid-fire gun forward.
It was planned in 1974–1975 to order four more Sparviero class hydrofoils, to be supplemented by at least two larger Pegasus class hydrofoils, but plans for a NATO-wide standardisation on the Pegasus class were abandoned. When orders were finally placed in 1977, they were for six more Sparvieros (giving seven in total) and no Pegasus class boats. The new ships, built by Fincantieri at Muggiano, entered service from 1982 to 1984, and differed from the prototype in having a more advanced installation for the Otomat missiles (using the Teseo control system) and having water injection fitted to the gas turbines.
