The Asagiri-class destroyer was built during the 1980s for service with the Japanese Maritime Self Defense Force. This class of general purpose destroyer is an extended version of its predecessor Hatsuyuki-class destroyers, and is mainly tasked with ASW and ASUW. The Asagiri-class vessels feature several enhancements and/or improvements over the Hatusyuki class, such as:
- COGAG Propulsion System.
- Compared with the COGOG propulsion system of the Hatsuyuki-class, this class has the COGAG propulsion system with enhanced capacity. The COGAG propulsion system is composed of four Kawasaki-Rolls-Royce Spey SM1A gas turbines.[1]
- Advanced radar systems.
- This class is equipped with the OPS-28 surface search radar. The OPS-28 is analogous to the American Target Acquisition System Mk.23 with the Track while scan capability. Later ships of this class introduced the OPS-24 air search 3D radar. The OPS-24 is the first shipboard active electronically scanned array radar in the world.[2]
- Full-configuration destroyer CDS.
- The earlier batch was equipped the OYQ-6 combat direction system (CDS). This system employed one AN/UYK-20 computer as the same as OYQ-5 tactical data processing system of the Hatsuyuki-class, but it can exchange tactical data via Link-11, which the OYQ-5 does not support. Later, all OYQ-6 systems were upgraded to the OYQ-7, integrated with OYQ-101 ASW Direction System.[3]
- All ships of this class were later retrofitted with the terminal for the MOF system, the key operational C4I system of the JMSDF which uses the Superbird SHF-SATCOM.[3]
- Enlarged aircraft facility.
- The hangar is enlarged in order to accommodate two helicopters, but generally only one helicopter is used operationally.[4]
Asagiri, Yugiri, and Amagiri were named after World War II destroyers. Amagiri's World War II namesake rammed and sank PT-109.
The Yamagiri and Asagiri have been converted into training vessels.
