Development and design

Hibiki-class vessels have a beam of 30 metres (98 ft 5 in), a top speed of 11 knots (20 km/h; 13 mph), and a standard range of 3,800 nautical miles (7,000 km; 4,400 mi). [5] Each vessel has a crew of 40, including five American civilian technicians, and a flight deck for helicopters to operate off of. [6] [7] They are able to deploy on station for 90 days. [7]

The vessels have an AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS), which was installed in the United States. [8] [7] Data from the sensors is relayed through the Defense Satellite Communications System and processed and shared with the United States. [7] The data is fed into the Integrated Undersea Surveillance System. [9]

Propulsion is provided by four Mitsubishi S6U-MPTK diesel electric engines. [10] [1]

Construction and career

Aki was laid down in October 2018 at Mitsui Engineering & Shipbuilding, Tamano and launched on 15 January 2020. [2] She was commissioned on 4 March 2021. [1] [3]

<span class="mw-page-title-main">Small-waterplane-area twin hull</span> Ship configuration with submerged twin-hulls

A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds. The bulk of the displacement necessary to keep the ship afloat is located beneath the waves, where it is less affected by wave action. Wave excitation drops exponentially as depth increases, so wave action normally does not affect a submerged submarine at all. Placing the majority of a ship's displacement under the waves is similar in concept to creating a ship that rides atop twin submarines.
