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.
