The Murasame-class destroyer (むらさめ型護衛艦, Murasame-gata-goei-kan) is a class of destroyers, serving with the Japan Maritime Self-Defense Force (JMSDF). This is the first class of the second-generation general-purpose destroyers of the JMSDF.[1]

Background

Since FY1977, the JMSDF started construction of general-purpose destroyers (汎用護衛艦, Hanyou-goei-kan) under the eight ships / eight helicopters concept.[2] In this concept, each flotillas would be composed of one helicopter destroyer (DDH), five general-purpose destroyers (DD), and two guided-missile destroyers (DDG).[3] By FY1986, construction of twenty first-generation DDs (twelve Hatsuyuki class and eight Asagiri class) required for all four flotillas had been completed.[2]

In the original plan, it was supposed to shift to destroyer escorts for local District Forces afterwards. However, if the use of these first-generation DDs was continued to the full extent of ships' life, the relative performance obsolescence was concerned. Thus the JMSDF decided to advance the construction of the new generation DDs. And this was the first class of the second-generation DDs.[1]

Except for Kirisame, all ships of the class are named after Imperial Japanese Navy destroyers sunk in World War II.

Design

The hull design was completely renovated from first-generation DDs. In addition to increasing the size in order to reduce the underwater radiation noise, both superstructure and hull were inclined to reduce the

mooring devices.[4][Note 1]

The engine arrangement is COGAG as same as Asagiri class, but a pair of engines are updated to Spey SM1C. And the remaining one pair are replaced by LM2500, same as Kongō class.[4]

Equipment

The basic configuration of the equipment is the same as first-generation DDs, but they are updated and enhanced throughout. Concepts of its combat system were partly based on those of Kongō class. Two large-screen displays and OJ-663 consoles are introduced in its OYQ-9 combat direction system as Aegis Weapon System (AWS). And OYQ-103 ASW combat systems, based on OYQ-102 of Kongō class and indirectly AN/SQQ-89, present an integrated picture of the tactical situation by receiving, combining, and processing active and passive sensor data from the hull-mounted array, towed array and sonobuoys.[6]

The advanced

electronic warfare suite and OQS-5 bow-mounted sonar.[4]

To enhance the low-observability and combat readiness capability,

Sea Sparrow (RIM-7M) to the Evolved Sea Sparrow by FY2012.[7]

The aircraft facility is expanded to accommodate two shipboard helicopters. One Mitsubishi SH-60J/K is a basic load, and another can be accommodated in case of overseas operation.[2]
