Although not as modern as the Akizuki-class destroyer, the Takanami-class warships are still considered the “trump card” of the Japanese Navy.

Takanami-class is a lightly modified second-generation multirole destroyer of the Japan Maritime Self-Defense Force. The Takanami class was built between 2000–2004 and consisted of five ships. The lead ship of the class, the Takanami DD-110, entered service in March 2003.

These ships have a full load displacement of 6,300 tons, a length of 151 m, a beam of 17.4 m, a height of 10.9 m, and a draft of 5.3 m. The hull design is generally based on the one of the Murasame-class. However, as a part of weapons was changed, the internal structure has also been changed. And it was said that the large lattice mast was degrading its stealthiness in the Murasame-class, so in this class, it was considered to change to two small masts, but it was not implemented.

Power is from a combined gas turbine arrangement involving 2 x Ishikawajima Harima LM2500 gas turbines and 2 x Kawasaki SM1C gas turbines. These generate upwards of 60,000 horsepower to drive 2 x Shafts astern, propelling the vessel to speeds of 30 knots in ideal conditions.

In terms of weaponry, The Takanami Class destroyers are fit with an Mk48 VLS (vertical launching system) for Evolved Sea Sparrow surface-to-air missiles. The Mk41 VLS installed on the ship can fire RUM-139 anti-submarine rockets. The Type 90 anti-ship missile has a maximum range of 200km. The ship has two triple-mount Type 68 anti-submarine torpedo tubes, firing six Mk46 ASW torpedoes. The main gun fitted forward is an Oto Melara 127mm gun. The close in air defence is provided by two Phalanx 20mm close-in weapons systems.

In addition, the vessel also supports a single Sikorsky SH-60J/K medium helicopter from the stern-based helipad with complete hangar facilities. The helicopter is outfitted with equipment for the Anti-Submarine Warfare role giving the Takanami more firepower against enemy submarines.

The sensor suite consists of OPS-28D surface search radar, OPS-24 3-D air-search radar and OPS-20 navigation radar. The OPS-28 is the Japanese equivalent of the American TAS Mk 23. The ship is also fitted with OQS-5 bow mounted medium frequency sonar and OQR-2 towed array sonar system.
