Akizuki-class Destroyer (2012)

From Canadian Power Wiki

Jump to: navigation, search

The Akizuki-class destroyer is a future destroyer class of the JMSDF - four ships are planned initially. The class is designed partly to "guard" Aegis destroyers in the Missile defense (MD) missions. This class was used to be called "19DD", derived from the Japanese calendar, specifically the 19th fiscal year of the Heisei period (2007).

The design of this class derives from the one of the Takanami-class destroyer, but there are many points improved. Main gas turbine engines are standardized with the power upped version of the Rolls-Royce Spey SM1C in contrast to the combination of the Rolls-Royce SM1C and the General Electric LM2500 which is used in Takanami-class.

The main features of the class are its enhanced C4ISR and AAW capability with the OYQ-11 advanced combat direction sub-system (ACDS) and the FCS-3A AAW weapon sub-system.

And also ASW and EW capabilities are enhanced with the OQQ-22 integrated sonar suite sub-system (hull-sonar and OQR-3 towed array; Japanese equivalent of the American AN/SQQ-89) and the NOLQ-3D digitalized EW suite sub-system. These sub-systems are integrated with NOYQ-1B Wide area network. The totality of these systems are comparable to the one of the Zumwalt-class destroyers.
