The Hatakaze class of guided missile destroyer is a 3rd generation vessel in service with the Japan Maritime Self-Defense Force (JMSDF). It marked the first of the JMSDF's ships that had 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 or an accident, 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 2 5 inch (Mk 42) 54cal caliber, rapid-fire guns.
