JMSDF to Take Delivery of First Maya-Class Destroyer JS Maya on March 19

The Japan Maritime Self-Defense Force (JMSDF) will take delivery of its first Maya-class guided-missile destroyer, JS Maya (DDG-179), on March 19, the service announced.

The delivery ceremony is scheduled at the Japan Marine United Corporation (JMU)’s Yokohama Shipyard Isogo Works facility.

JS Maya was laid down by JMU in Yokohama, Kanagawa on April 14, 2017, and was launched on July 30, 2018. She is named for Mount Maya and shares her name with World War II-era Japanese Takao-class heavy cruiser Maya.

Maya-class DDGs

Maya-class ships are Japan’s latest Aegis-equipped guided-missile destroyers developed from the currently operational Atago-class destroyers.

The vessels have a length of 170 meters, a width of 21 meters, a standard displacement of 8,200 tons and a full load displacement of 10,250 tons. The ships will have a crew complement of around 300.

The Maya-class features the newer Aegis Baseline 9 system (referred to as J7 in Japan) while the Atago-class uses the older Aegis Baseline 7 system. The Maya-class is also the first JMSDF AEGIS vessel to be ready for ballistic missile defense (BMD) from the time of its commissioning. The Atago-class and the older Kongō-class destroyers underwent modifications to be able to conduct BMD.

The new destroyers are equipped with the Cooperative Engagement Capability (CEC) system which will allow them to share surveillance or targeting information with other CEC-equipped Japanese and allied assets such as ships and aircraft.

The ships are armed with one 5-inch (127mm/L62) Mk-45 Mod 4 naval gun in a stealth-shaped mount, two 20 mm Phalanx Close-In Weapon Systems (CIWS), SM-3 Block IIA and SM-6 air/missile defense missiles and Type 17 ship-to-ship missiles.

The first ship of the class, JS Maya, was launched on July 30, 2018, and the second ship of the class, the future JS Haguro (DDG-180), was launched on July 17, 2019. The second ship is expected to enter service next year.
