Development and designEdit

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).[1] Each vessel has a crew of 40, including five American civilian technicians, and a flight deck for helicopters to operate off of.[2][3] They are able to deploy on station for 90 days.[3]

The vessels have an AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS), which is installed in the United States.[4][3] Data from the sensors is relayed through the Defense Satellite Communications System, and processed and shared with the United States.[3] The data is fed into the Integrated Undersea Surveillance System.[5]

Propulsion is provided by four Mitsubishi S6U-MPTK diesel electric engines.[6]

Construction and careerEdit

Hibiki was laid down on 28 November 1989 at Mitsui Engineering & Shipbuilding, Tamano and launched on 27 July 1990. She's commissioned on 30 January 1991. Currently, her homeport is in Kure.[citation needed]

After deployment, from 9 March 1991, the same year, it was circulated to Oakland, California, USA for proficiency training after service, and after learning the SURTASS system, it was equipped with a sonar array in Pearl Harbor, Hawaii, and after the equipment certification test was completed, she returned to Japan on 17 October, the same year.[citation needed]

Full-scale operation started in April 1992, and the actual operation was where the anti-submarine information analysis center on land began.[citation needed]

On 1 December 2015, the Oceanographic Command Group was reorganized into the Oceanographic Command and Anti-submarine Support Group, and was incorporated into the 1st Acoustic Measurement Corps, which was newly formed under the same group.[citation needed]

On 1 November 2017, the crew system was introduced to the 1st Acoustic Measurement Corps for the first time as a JMSDF ship, and from now on, the crew will not be fixed, and 3 crews will operate two ships alternately.[7]
