Background
editSince FY1977, the JMSDF started construction of general-purpose destroyers(Phiếm dùng tàu bảo vệ,Hanyou-goei-kan)under the eight ships / eight helicopters concept.[2]In this concept, each flotillas would be composed of onehelicopter destroyer (DDH),five general-purpose destroyers (DD), and twoguided-missile destroyers(DDG).[3]By FY1986, construction of twenty first-generation DDs (twelveHatsuyukiclassand eightAsagiriclass) required for all four flotillas had been completed.[2]
In the original plan, it was supposed to shift todestroyer escortsfor localDistrict Forcesafterwards. 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 forKirisame,all ships of the class are named after Imperial Japanese Navy destroyers in World War II.
Design
editThe 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 theradar cross-section.There is however no angled tripod mainmast like the one of the AmericanArleigh Burke-class destroyerbecause of the heavy weather of theSea of Japanin winter. The aft was designed like a "mini-Oranda-zaka"as with theKongōclassto avoid interference between helicopters andmooringdevices.[4][Note 1]
The engine arrangement isCOGAGas same asAsagiriclass, but a pair of engines are updated toSpey SM1C.And the remaining one pair are replaced byLM2500,same asKongōclass.[4]
Equipment
editThe 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 ofKongōclass. Two large-screen displays and OJ-663 consoles are introduced in its OYQ-9 combat direction system asAegis Weapon System (AWS).And OYQ-103 ASW combat systems, based on OYQ-102 ofKongōclass and indirectlyAN/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 andsonobuoys.[6]
The advancedOPS-24active electronically scanned arrayradar and OPS-28 surface search and target acquisition radar introduced into the fleet with the latter batch of theAsagiriclassremain on board, and there are some new systems like the NOLQ-3electronic warfaresuite and OQS-5 bow-mounted sonar.[4]
To enhance the low-observability and combat readiness capability,vertical launching systemswere adopted on its missile systems: Mk 41 forVL-ASROCand Mk 48 forSea Sparrowreplace the traditional swivel octuple launchers. And thesurface-to-surface missilesystem is alternated by theSSM-1Bof Japanese make.[4]Currently, ships of this class have been switching the point defense missile system from the traditionalSea Sparrow(RIM-7M) to theEvolved Sea Sparrowby FY2012.[7]
The aircraft facility is expanded to accommodate twoshipboard helicopters.OneMitsubishi SH-60J/Kis a basic load, and another can be accommodated in case of overseas operation.[2]
