[2] The Hayabusa was the first CODAG propulsion boat of the Maritime Self-Defense Force to experimentally equip a gas turbine for boosters in addition to diesel as the main machine.

[3] The gas turbine mounted on the Hayabusa was a MUK501 developed by the Technical Research and Development Institute of the Defense Agency (at that time) and manufactured by Mitsubishi Shipbuilding Nagasaki Shipyard & Machinery Works, and is the same as the one mounted on the training ship Hokuto Maru of the Ministry of Transport.

[3] Since the Hayabusa was a high-speed boat that used a gas turbine as its engine, various considerations were made, and the bridge and other parts had a similar appearance to the Kari and Kamome-class, but the hull shape was large.

Unlike, it has a large knuckle on the side from the bow to the bridge, improving the seakeeping ability during high-speed navigation.

The deck room at the rear of the bridge was equipped with a large chimney for gas turbines and intake ports for gas turbines on both sides, and a small funnel for diesel main engines was installed on the rear deck room.
