Geshrinari Shipyards developed the Modular Aether Plasma Drive based on the Ketsurui Fleet Yards Turbo Aether Plasma Drive. It was developed for the Urufu-Class Light Cruiser. They designed the drive to be completely modular, including the entire drive. At a properly equipped facility a complete swap of a MAPD can be accomplished in three hours.
Functionality wise this drive operates the same as the KFY Turbo Aether Plasma Drive. As such this engine is restricted technology and only available for Star Army of Yamatai vessels.
