The 1-go class (1号型ミサイル艇（いちごうがたミサイルてい)

... (Italian Sparviero / Nibbo class), were small fast attack hydrofoil missile boats capable of traveling at speeds of 46 knots (85 km/h; 53 mph). They were designed for and formerly used by the Italian Navy (7 units).
The Japanese 1-go-class missile boat (PG) is an updated version formerly used by the Japan Maritime Self-Defense Force (JMSDF).

The Japan Maritime Self-Defense Force (JMSDF) selected a modified version of the Sparviero class as a replacement for its PT 11-class torpedo boats. A license agreement was signed in 1991 to build up to 12 Sparvieros, with the first two approved in FY90 and both were laid down by Sumitomo in Uraga on 25 March 1991. An order for a third boat was delayed to help pay for Japan's contribution to the Gulf War, with it not being laid down until 1993. A request for a fourth boat under the FY 95 budget was rejected, and plans for further hydrofoils abandoned.

The Japanese chose different armament than used in the Italian boats, with up to four Type 90 SSM-1B Anti-Ship Missiles replacing the Italian Otomats and a non-stabilised 20 mm (0.79 in) M61 Vulcan rotary gun replacing the larger Oto Melara 76/62 gun. The main powerplant is a 3,900 kW (5,200 shp) General Electric LM500 gas turbine, built in license by IHI.
