Maya-Class AEGIS Guided-Missile Destroyer (DDG)

The ***Maya* class** of guided missile destroyers (まや型護衛艦, *Maya-gata Goeikan*) 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, 1644 CC (March 19, 2020, AD).

## Overview

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.

The JMSDF already uses an integrated electric propulsion system for auxiliary vessels, and is expected to expand to surface combatant ships in the future in light of its future weapon accommodation.

The Aegis system equipped on the Maya is different from the earlier AEGIS-equipped JMSDF ships. Unlike the Atago-Class, BMD ability is installed from the beginning. Also, unlike the Kongo-Class, it is possible to perform BMD and normal anti-aircraft combat at the same time. Construction was in jeopardy because the transfer made it impossible to import the AEGIS system, but since the first ship Maya was commissioned, Japan has succeeded either in developing a copy of the AEGIS or the ATECS was installed instead of the AEGIS and managed to make it on par with the US-made AEGIS. In the case of copying the AEGIS, the baseline may be different from the real-life Maya-class.

## Service History in the New World

### New World War Arc

As part of the JMSDF's First Escort Squadron, the ship, along with 9 other JMSDF warships, were tasked to take part of the naval blockade on Leifor along with the Holy Milishial Empire's newly-formed Death Bar Fleet.
