The Takatsuki-class destroyer was a series of four destroyers constructed for and operated by the Japan Maritime Self-Defense Force. Built between 1964 and 1970, the destroyers were mainly used for anti-submarine warfare (ASW) duties and were designed to operate the DASH unmanned ASW drone system. The system did not work and was removed from all four ships in 1977. In the mid-1980s, the first two ships of the class were modernized, receiving surface-to-air and anti-ship missiles. The final two ships were scheduled to be modernized, but the program was cancelled.

Modernization

From 1985 to 1988, Takatsuki and Kikuzuki were upgraded with Sea Sparrow surface-to-air missile 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.^[1]
