MATSUYUKI DD 130

FONTE: WIKIPEDIA
This class is made a number of firsts among general purpose destroyers of the JMSDF.

It was the first class to use Combined gas or gas (COGOG) propulsion system. The all-gas-turbine propulsion system is composed of two Kawasaki-Rolls-Royce Tyne RM1C gas turbines for cruising and two Kawasaki-Rolls-Royce Olympus TM3B gas turbines for high speed operation. It introduced the concept of total ship systems engineering with an integrated combat system. The core of the combat system is the OYQ-5 Tactical Data Processing System (TDPS). The OYQ-5 TDPS is composed of one AN/UYK-20 computer and five OJ-194B workstations, and capable of receiving data automatically from other ships via Link-14 (STANAG 5514).

This is the first destroyer class in the JMSDF equipped with the Sea Sparrow Improved basic point defense missile system and Boeing Harpoon surface-to-surface missile system for AAW and ASuW respectively. The IBPDMS of this class uses FCS-2 fire-control systems of Japanese make and one Mk.29 octuple launcher at the afterdeck.

The class introduced the capability to operate an ASW Helicopter. While the JMSDF already had the Haruna class of "helicopter destroyer", the Hatsuyuki class were the first air-capable general purpose destroyer class. Although it has a small aviation deck, through a beartrap system, the class can operate the Sikorsky HSS-2B Sea King anti-submarine helicopter safely in a wider range of weather conditions.
The Matsuyuki (DD-130) was fitted with a towed sonar array in 1990, followed by the Hatsuyuki (DD-122) in 1994, work ongoing to apply the fit to the rest of the class.
