The Hatsuyuki-class destroyer (はつゆき型護衛艦 Hatsuyuki-gata-goei-kan) is a class of destroyer, serving with the Japan Maritime Self-Defense Force (JMSDF). It was the first class of general-purpose destroyers of the first generation of the JMSDF.

Destroyers of the JMSDF had been divided into two series, anti-aircraft gun fire oriented destroyers (DDA) and ASW-oriented destroyers (DDK). However, in the 1970s, a drastic review of the fleet became necessary due to the enhancement of the Soviet submarine fleet and the reinforcement of the anti-ship missiles. After consideration by Operations research, eight ships / eight helicopters concept was adopted as a new fleet organization. In this concept, each flotillas would be composed of one helicopter destroyer (DDH), five general-purpose destroyers (DD), and two guided missile destroyers (DDG).
General-purpose destroyers (汎用護衛艦 Hanyou-goei-kan) is a new type of destroyers for this concept, combines anti-aircraft capability like DDA and anti-submarine capability like DDK, and also capable of the operation of missiles and helicopters. And this was first class to be built as the first ships based on this concept.
The hull structure was based on the shelter deck style adopted in the Isuzu class, and a long forecast style was adopted which truncated the rear end. The shape under the water line resembles JDS Amatsukaze. In order to reduce the noise, Prairie-Masker was installed after the 3rd ship and was also equipped with the 1st and 2nd ship at a later date.
From DD-129 onward, steel replaced aluminium for key elements of the superstructure including the bridge from the viewpoint of resistance and durability. However, due to this design change, the ballast had to be installed, the displacement increased and the movement performance was deteriorated.
It was the first class to use combined gas or gas (COGOG) propulsion system in the JMSDF. 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.
This combination and mounting method of these engines are similar to the Type 21 frigates of the British Royal Navy, so it was not possible to adopt an alternating engine room arrangement like a conventional JMSDF destroyer, the lack of redundancy was pointed out.
The core of the combat system is the OYQ-5 Tactical Data Processing System (TDPS), 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. The IBPDMS of this class uses FCS-2 fire-control systems of Japanese make and one octuple launcher at the afterdeck. And in the JMSDF, OTO Melara 76 mm compact gun and Boeing Harpoon surface-to-surface missile are adopted from the ship of FY1977 including this class. Also, ships built in FY1979 and beyond carried Phalanx CIWS and were retrofitted to previous ships.
This class introduced the capability of shipboard helicopter operations. While the JMSDF already had the Haruna-class "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 Mitsubishi HSS-2B anti-submarine helicopter safely in a wider range of weather conditions. Later, HSS-2B was replaced by Mitsubishi SH-60J, but there was no room to install a large data link device for SH-60J, so a simplified type was installed.
Initially planned to carry out passive operation with sonobuoys laid by helicopters and towed array sonar (TASS) as sensors, but because development of TASS was delayed, it was retrofitted later on only four ships. OQS-4 hull sonar was Japanese equivalent of American AN/SQS-56, and OQR-1 TASS was of AN/SQR-19.

The Takatsuki class destroyer was a vessel of the Japan Maritime Self-Defense Force. It was the predecessor of the Hatsuyuki-class destroyer, and was mainly used for anti-submarine warfare duties.
In 1985-1988, Takatsuki and Kikuzuki were upgraded with Sea Sparrow SAM launchers, Harpoon missile anti-ship missile launchers, Phalanx CIWS systems (Kikuzuki only), new FCS (FCS-2-12) fire control radar and TASS. Mochizuki and Nagatsuki were in the upgrade program, but were eventually not upgraded.
