Japan’s second Asahi-class destroyer, the JS Shiranui, entered Japan Maritime Self Defense Force (JMSDF) service in a ceremony at Mitsubishi Heavy Industries’ Nagasaki Shipyard on February 27.

The lead ship in the class was commissioned a year before, on March 8, 2018.

The 5,100-ton general-purpose escort destroyers were previously designated as 25DD and are designed on the basis of Akizuki-class destroyers but with a focus on anti-submarine instead of anti-air warfare.

JS Shiranui (DD-120) was launched in October 2017 and was commissioned without delays.

Asahi-class destroyers are lauded as fuel-efficient ships featuring COGLAG, a combined gas turbine engine and electric propulsion system. They measure 151 meters in length and reach speeds of 30 knots, according to the Japan defense ministry. Armament includes Mark 41 vertical launch systems for self protection, 62-caliber naval guns, close-in weapon systems and two Mark 32 surface vessel torpedo tubes.

The destroyers will have a complement of around 230 and embark one Mitsubishi-built SH-60J/K are anti-submarine patrol helicopter.

Asahi-class destroyers are the first JMSDF ships to deploy with periscope detection radars in addition to being equipped with new towed array sonars.
