The Akizuki class was built between 2009 and 2012, consisting of four ships: Akizuki, Teruzuki, Suzutsuki, and Fuyuzuki.

With state-of-the-art equipment, the Akizuki-class is said to be the most modern destroyer class of the Japan Maritime Self-Defense Force today. The Akizuki class was built between 2009 and 2012, consisting of four ships: Akizuki, Teruzuki, Suzutsuki, and Fuyuzuki. The class was designed to escort the Hyūga-class and Izumo-class helicopter destroyers, and to protect other Aegis-capable warships such as the Kongō-class and Atago-class.

The Akizuki class has a full load displacement of about 6,800 tons, a length of 150.5 m, a beam of 18.3 m, and a draft of 5.3 m. The vessels provide defense against surface, airborne and undersea threats.


The hull structure is based on the Takanami-class destroyer, with many small improvements, such as cleaner lines to reduce the radar signature and decoys for torpedoes; but the principal changes can be summed up as more powerful engines, sensors, sonar and the indigenous ATECS battle management system that has been called the Japanese AEGIS. The design incorporates a low radar cross section mast to enhance stealth capability.

The propulsion system is a Combined gas and gas configuration, consisting of four Rolls Royce Spey SM1C turbines, driving two shafts. The engines incorporate latest digital control technology. The propulsion system provides a maximum speed of 30kt. The vessel can accommodate 200 crew members.

The Akizuki Class is equipped with an indigenously developed advanced technology command system, also known as the Japanese variant of Aegis, includes a phased array radar, high-speed data processing systems and a shipboard combat system. The system integrates UYQ-70 display and control units and subsystems. It receives and processes the information from the various weapon systems including 3-FCS-3 fire control systems, an integrated anti-submarine system and an electronic warfare control system.

The ship’s most powerful weapon is eight Type 90 anti-ship missiles, which is a ship-launch version of the Type 88 surface-to-ship missile. It has the range of 150km to 200km by using an inertial and active radar guidance system. In addition, a Mk41 vertical launch system is fitted for launching RIM-162 Evolved Sea Sparrow Missiles, RUM-139 VL-ASROC and Type 07 VL-ASROC.

Other weapon includes a Mk45 5in lightweight main gun fitted forward in the vessel. The destroyer also features two 20mm Phalanx Block1B CIWS to provide point defence against incoming short range missiles, rockets and low-flying fixed-wing aircraft. The Akizuki Class is fitted with two 324mm HOS-303 triple torpedo tubes firing six torpedoes. The stern area has a helipad and a hangar that can accommodate two SH-60K anti-submarine helicopters.

It can be seen that, despite its compact size, the power of the Akizuki-class can make any enemy warship terrified.
