Dodai YS

Dodai YS

The Dodai YS was a mobile suit sub-flight system mass produced by the Principality of Zeon. It could also function as a bomber.


The Principality of Zeon designed the Dodai YS as a mobile suit sub-flight system to give its mobile suits atmospheric flight capability.

During the course of the war, the Zeon also created the Dodai GA , a unit focused on anti-ground attacks, along with the upgraded Dodai II . In UC 0080, salvaged Dodai YS units were utilized by the breakaway South Seas Alliance as part of its defense forces. These remodeled units featured two fewer missile launchers than the original Zeon version. The Dodai YS was succeeded by the all-environment use Dodai Custom deployed by the AEUG during the Gryps Conflict in UC 0087. However, the original Dodai YS remained in service with Earth-based Zeon remnants as late as UC 0096.

Zeon also created the Dodai GA that specialised in anti-ground attacks, and the improved Dodai Kai . The South Seas Alliance deployed salvaged Dodai YS units during its war for independence.

The Dodai Custom was the successor to the Dodai YS that could be used both in the atmosphere and space. Despite this, the Dodai YS remained in service and several units were deployed by Zeon remnant forces in UC 0096.

Mobile suits were developed by Principality of Zeon initially for space battles. When the Zeon forces were deployed on Earth, they realised that the mobile suits lacked flight capability.

To overcome this weakness without having to resort to expensive modifications that might reduce the battle capabilities of the suits, the Zeon engineers designed the Dodai YS. Originally developed as a bomber, Zeon converted it into a sub-flight system to carry mobile suits.

The Dodai was an independent aircraft that acted as a platform to carry the mobile suit. This allowed it to ferry different mobile suits since it was not fixed to one particular unit.

Due to its limited air-to-air combat capabilities, it often had an escort of Dopp fighters.


The Dodai was equipped with eight missile launchers. These could be used for air-to-surface or air-to-air attacks. The remodelled versions used by the South Seas Alliance had two fewer missile launchers.
