The Maya class of guided missile destroyers in the Japan Maritime Self-Defense Force is a modified version of the Atago class, with an updated Aegis Combat System and electric propulsion system. Maya was commissioned on March 19, 2020 and the Haguro was commissioned on March 19, 2021. 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. Maya-class destroyers are engineered with a COGLAG (Combined Gas turbine-eLectric And Gas turbine) propulsion system, a modification of the combined gas and gas propulsion system employing turbine-electric transmission for low-speed cruising. The JMSDF had been testing a COGLAG propulsion system on JS Asuka. Then, the adoption of the system for surface combatants began with the Asahi class. While the Asahi-class system had a low voltage distribution of 450 volts, the Maya-class system is equipped with a more advanced system that can handle a high voltage distribution of 6,600 volts.
