Shipbuilding company Japan Marine United (JMU) Corporation launched the second of two Maya (Improved Atago)-class destroyers on order for the Japan Maritime Self-Defense Force (JMSDF) on 17 July.

Named Haguro (pennant number 180), the 170 m-long vessel entered the water in a ceremony held at JMU's facility in Yokohama City, and is expected to be commissioned in March 2021.

The destroyer, which will be the eighth JMSDF ship to be equipped with the Aegis Combat System, is 5 m longer than the Atago-class destroyers operated by the JMSDF.

Haguro will use the Aegis Baseline J7 supported by the Lockheed Martin/Raytheon AN/SPY-1D(V) phased array radar and the Northrop Grumman AN/SPQ-9B X-band (NATO I-band) (8-12.5 GHz) high-resolution fire-control radar.

The ship, which cost about JPY173.4 billion (USD1.6 billion) to build, will be equipped with the US-developed Cooperative Engagement Capability (CEC) system, which will enable the destroyer to act as part of a wider 'grid' of sensors and weapon platforms that allow other CEC-equipped ships to share surveillance and targeting information.

The JMSDF also plans to provide first-of-class Maya , which was launched on 30 July 2018 and is expected to enter service in March 2020, with this capability to better counter threats such as those posed by North Korean ballistic missiles.

The Maya class has a standard displacement of 8,200 tonnes, which is 450 tonnes more than the Atago-class ships. Powered by two General Electric LM2500 gas turbines in a combined gas turbine-electric and gas turbine (COGLAG) configuration, each of these platforms can reach a top speed of 30 kt, according to JMU.

The destroyers, each of which has a crew of about 300, are also equipped with multifunction towed array (MFTA) sonar systems and electronic warfare (EW) capabilities.
