The Hatsuyuki-class is a class of twelve anti- submarine destroyers of the Japanese Marine Self- Defense Forces (JMSDF) . They were their standard escort ships and can be found in every association. They were partly replaced by the units of the Akizuki class .
history
Development and construction
The Hatsuyuki-class ships were planned to replace the obsolete Yamagumo-class anti- submarine ships in the late 1970s . The main task of the destroyers was supposed to be the submarine hunt , which is why they were equipped with extensive armament and sensors for tracking down and fighting enemy submarines.
The first units were laid down in 1979 and put into service in 1982, the last ship was completed in 1987. Of the twelve ships originally built, six are still in active service, the Setoyuki , Shirayuki and Shimayuki have been reclassified as training ships . The cost of the first unit was 30.6 billion yen and the final unit was 37.5 billion yen.
In contrast to the first ships, the superstructures of the last five units of the class were made of steel instead of light metal, which increased the displacement by 100 tons and the draft increased by 0.1 m.
In the 1980s, the Asagiri class was developed based on the Hatsuyukis , the hull of which was lengthened by 7 m compared to its predecessors.

technology
Hull and drive
The hull of a Hatsuyuki-class destroyer is 130 m long and 13.6 m wide. The draft is 4.2 m (4.3 m for DD-129 to DD-133), the displacement is 2,950 ts (3,050 ts for DD-129 to DD-133). The superstructures are characterized by the large chimney, which is required for the gas turbine drive. At the stern is the helicopter landing pad, in the superstructure in front of the hangar, in which an on- board helicopter can be carried.
The drive is provided by four gas turbines, two Kawasaki RR Olympus TM3B with 34 MW for cruising and two switchable RR Type Kawasaki RM1C with 7.4 MW for high-speed driving. The power is delivered to two shafts with one screw each. The maximum speed is 30 knots (56 km / h), the normal cruising speed 19.5 knots.
Armament and Electronics
The eight-cell ASROC starter in front of the bridge , together with the two triple torpedo tubes on the sides of the superstructure, forms the main anti -submarine armament. In front of the ASROC starter there is a 76 mm rapid fire gun from Oto Melara , from the late 1980s onwards all ships were retrofitted with two Phalanx CIWS each . To combat surface ships, there is a quadruple starter for RGM-84 Harpoon on both sides of the chimney. For air defense, the Hatsayukis have a Sea Sparrow Mk 29 starter on the stern.
As aerial reconnaissance radar use the destroyer OPS-148 - 3D radar that Seezielsucher done with the OPS-18 -Radar. The ships have two GFCS-1 radars to fire control the gun, while the anti-aircraft missiles are fire controlled by a GFCS-2 radar, the antenna of which is located under the dome-shaped cover on the hangar. For the detection of underwater targets the ships have a OQS-4 -Niederfrequenz- Bugsonar , since 1994 they are also equipped with a SQR-19 - towed array sonar equipped.
