The Maya-class are currently the newest destroyers of the Japan Maritime Self-Defense Force.
The lead ship of the class, JS Maya DDG-179 was commissioned on March 19, 2020, the other, JS Haguro DDG-180 commissioned on March 19, 2021. This is a modified version of the Atago class, with an updated Aegis Combat System and electric propulsion system.
The Maya class was built to replace the obsolete Hatakaze class, which comes with ballistic missile defense capabilities. Each unit costs around $1.5B. The destroyer class has a full load displacement of about 10,250 tons, a length of 169.9 m, a beam of 22.2 m, and a draft of 6.4 m.
While it shares the same design characteristics as the Atago class, the Maya class possesses a larger hull to install a hybrid-electric propulsion system. This includes two LM2500-30 gas turbines, two propulsion motors and two two-axis variable pitch propellers, with a capacity of 68,000 hp. The ship can reach a top speed of 30 knots. The LM2500 gas turbines feature dual-fuel capability and offer greater efficiency while reducing operating costs.
The Maya class features the newer Aegis Weapon System Baseline 9C, compared with the Atago class using the Baseline 7 system. With this system, these destroyers are equipped with the Cooperative Engagement Capability system (CEC). This will allow the ship to share surveillance or targeting information between other assets.
In addion to the Aegis Weapon System, they are also equipped with an Aegis BMD 5.1 system; they are the first JMSDF Aegis vessels to be capable of ballistic missile defense from the time of its commissioning.
The structure of the Maya utilizes all known and proven signature-reducing features including slab sides and enclosed mastworks and smoke funnels. A low-profile design also aids in keeping the Maya a small target on the horizon. Couple these qualities with its onboard systems and the vessel sports many survivability features needed of modern warship types.
