Takanami-class

The Takanami-class is a series of five general-purpose destroyers in service with the Japan Maritime Self-Defense Force (JMSDF). Development began in FY1998 as a modified version of the preceding Murasame class. The vessels were constructed between 2000 and 2004, succeeding the Murasame class and preceding the Akizuki class.

The hull design is based on the Murasame class, though internal structures were altered to accommodate different weapon systems. While initial plans included the transition to two smaller masts to reduce the radar cross-section, the class instead retained the large lattice mast of the previous design. The propulsion system remains the same as that used in the preceding class.

Combat system hardware was updated during the production cycle. The first three ships utilize the same combat direction system as the Murasame class, while the fourth ship uses AN/UYQ-70 workstations and the fifth ship incorporates Link 16 communication capabilities. The sensor suite includes surface-search, navigational, and fire-control radars, along with a revised sonar system and towed sonar.

Armament configuration was modified from earlier designs. The class replaced the 3-inch gun used on previous destroyers with a larger-caliber main gun. The vertical launching systems, which were located in two separate areas on the Murasame class, are consolidated into a single Mk 41 VLS on the bow deck. This system houses both surface-to-air and anti-submarine missiles. The vessels also carry anti-ship missile canisters, triple torpedo tubes, and two close-in weapon systems. A hangar and helipad support the operation of one anti-submarine helicopter.

Five vessels were completed by Mitsubishi Heavy Industries and IHI Marine United. The ships were commissioned between 2003 and 2006. All vessels—Takanami, Ōnami, Makinami, Sazanami, and Suzunami—remain active. They are assigned to the homeports of Yokosuka, Ōminato, and Kure.
