A land battleship that the ReZeon utilizes as its main force. A battleship that has been upgraded and developed based on the Alexandria-class space cruiser. Within the ReZeon, there are numerous cases of modifying the equipment of captured Titans as ReZeon versions. In addition to modifying, the Mars Arcadia plant has changed designs and utilize many newly produced ones. This Gran-Xandria:Re-class land battleship is one such weapon.

The Alexandria-class that became the base for this ship is a warship that was built using Federation Forces technology with reference to the Musai light cruiser of the former Principality of Zeon. If tracing back, the mobile suits utilized by the ReZeon are similar, drawing from the Principality of Zeon engineering as a source. For example, the the RMS-106 Hi-Zack has redesigned elements from the Zaku and the Titans-made mobile suits have mono eyes such as the RMS-154 Barzam. In other words, the Titans equipment wasn’t captured from the Federation Forces for ReZeon but rather the technology originated from the Principality of Zeon returned to its original owner–sometimes referred to as “returning home”.

For this reason, the ReZeon actively brought in equipment captured from the Titans and proceeded with mass production and deployment (this is because the Zeon remnant hunting unit once targeted with psychological effects of “harassment” toward the enemy, so there was also a meaning of revenge for the hunted Zeon by using mobile suits with Zeon-like appearances).

Alice, the Supreme Commander, has advocated that the ReZeon is not an organization of Zeon remnants but rather a newly reborn organization on Mars. For that reason she thought that weapons that were once apart of the Principality of Zeon were unsuitable and instead armed their organization with weapons captured from the Titans. In contrast to this, however, ReZeon emphasized the ideology and traditions of the Principality of Zeon and even cultivated it in the exterior of their weaponry. Because of this ideology ran counter, two organizations that consider Zeon their ancestry continued their internal dispute over Martian hegemony.

A modified Alexandria-class battleship that takes over the trend of the Musai-class and has pronounced characteristics of Zeon vessels both with its internal mechanisms and exterior appearance. For its modifications, the main hanger in the center of the hull has been expanded forward and backwards, increasing the number of mobile suits that can be loaded on several times over.

Adopting a structure that is similar to the Chivvay-class, it is equipped with a takeoff and landing hatch on the bow. The arrangement of the main nozzles on both sides follows the traditions of the Musai-class. The layout which has semi-built-in round tanks is a structure that can be seen linking it to the Muska-class.

Equipped with Minovsky Craft as a propulsion unit, it is operated as a land battleship by using it together with its hover mechanism. With the no-fly zone on Mars, restrictions of not being flight capable were imposed not only on this ship, but on all kinds of weapons. Nonetheless, in the event of an emergency such as an attack from a foreign enemy from outer space, it is possible to escape from the atmosphere by detaching the hover units installed on the bottom of the hull.

This ship is operated as the capital ship of the ReZeon and it is deployed together with captured and modified ships. The shape of the bridge section is different for each ship and it can be said that there are various variations. For example, the forth ship Clark is deployed around all five important places on Mars (the spaceport, plant, urban area, crater and secret glacier base), and Alice’s special forces was on board during “Operation Radiant Star” and was deployed for the defense of Arcadia Plant.
