The Hatakaze class of guided missile destroyer is a third generation vessel in service with the Japan Maritime Self-Defense Force (JMSDF). They were the first of the JMSDF's ships to have gas-turbine propulsion.
The core weapon suite is similar to that of the Tachikaze-class destroyer, but various improvements were made in many areas. Most notable are those that allow the Hatakaze class to function as a group flagship. Normally this duty resides with the DDH class, but in case of a DDH being absent due to repairs, accident, or battle damage, the Hatakaze design allows for it to function as a command ship.
Hatakaze destroyers operate the OYQ-4-1 type tactical control system. Its weapon systems include the Standard missile surface-to-air missile, anti-submarine rockets, the RGM-84 Harpoon anti-ship missile, two Mark 15 20 mm CIWS gun mounts, two torpedo mounts in a triple tube configuration and two 5 inch/54 caliber Mark 42 rapid-fire guns.
