The Asagiri-class destroyer was built in the mid-1980s and late 1980s and is in service with the Japanese Maritime Self Defense Force.
This class of general purpose destroyer is almost extended version of its predecessor Hatsuyuki-class destroyers, and similarly, it mainly tasked with ASW and ASUW. There are many points enhanced as followes:
- The 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.
- Advanced radar systems
- This class is equipped with the new surface search radar, OPS-28. The OPS-28 is analogous to the American Target Acquisition System Mk.23 with the Track while scan capability. And the latter batch 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.
- The full-configuration destroyer CDS
- This class is equipped with the OYQ-6/7 combat direction system (CDS). The OYQ-6 has two AN/USQ-20 computers, and they were replaced by one AN/UYK-7 computer in the OYQ-7 on the latter batch. The OYQ-6/7 can exchange tactical data via Link-11 whereas the OYQ-5 tactical data processing system on the Hatsuyuki-class does not support. And later, all ships of this class back-fitted with the terminal for the MOF system, the key operational C4I system of the JMSDF which uses the Superbird SHF-SATCOM.
- Enlarged aircraft facility
- The hangar is enlarged in order to accommodate two helicopters, but in the operational configuration, there is only one.
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.
