The Japan Maritime Self-Defense Force (JMSDF) commissioned its first Asahi (25DD)-class guided-missile destroyer in a ceremony held on 7 March in Nagasaki Prefecture.

Named JS Asahi (with pennant number 119), the 151 m-long vessel was inducted into the service’s Escort Flotilla 2, based in Sasebo, shortly after being handed over by shipbuilder Mitsubishi Heavy Industries (MHI), according to a JMSDF statement. Asahi was launched in October 2016 and began sea trials in mid-2017.

The JMSDF is expected to operate a total of four destroyers of the class. The second ship, Shiranui , was launched by MHI on 12 October 2017.

According to Jane’s Fighting Ships , the Asahi class has a standard displacement of 5,100 tonnes (5,628 tons) and is powered by two General Electric LM2500 gas turbine engines in a combined gas turbine-electric and gas-turbine (COGLAG) configuration.

The class has a top speed of 30 kt, a crew complement for 230 personnel, and is able to accommodate one Mitsubishi (Sikorsky) SH-60 helicopter on the flight deck.

As Jane’s previously reported, the Asahi class is armed with a MK 45-series 127 mm naval gun and two MK 15-series Phalanx 20 mm close-in weapon systems (CIWS). Asahi is equipped with launchers capable of deploying the Type 90 anti-ship missile and the RIM-162B Evolved Sea Sparrow Missile (ESSM) Block I surface-to-air missile.

The warship’s anti-submarine warfare (ASW) capabilities are provided by six (two triple) 324 mm torpedo tubes for MK 46-series lightweight torpedoes, an OQQ-24 hull-mounted sonar, and an OQR-4 tactical towed array system (TACTAS).
