The Hayabusa-class is a guided missile patrol boat class of the Japan Maritime Self-Defense Force (JMSDF).

The Japan Maritime Self-Defense Force initially built three hydrofoil missile boats of the PG 1-go class between 1993-95.

[citation needed] The boat's displacement was enlarged to four times that of the PG 1-go class to improve seaworthiness.

Three LM500-G07 gas turbine engines, built under license from General Electric by Ishikawajima-Harima, provide the main propulsion.

The main armament is a pair of SSM-1B ship-to-ship missile twin launchers installed in the stern and an Otobreda 76 mm gun on the front deck.
