The Azashar-class Cityship, often referred to as the Robotech Masters' Mothership, or simply Mothership, was the main command battlefortress and colony ship of the Robotech Masters, and was seen in Robotech: The Masters.
The Azashar-class was a gargantuan mass of metals, ceramics and organics, massing as much as 350 Macross-class battlefortresses. The main hull was shaped in an irregular hexagonal platform, with the longitudinal side far larger than the other four sides. On top of the hull were two rather distinct features: a round pyramid on the forward portion of the ship, and a large elevated rectangle capped by two sloping planes. The latter feature gave the impression of a roof built on top of the vessel. The rest of the surface was not flat, but resembled very much the streets and stone canyons of a city. However, there were no windows or portholes present. Under the hull were three features of the ships, two hyperspace sensor horns and a large cone of metal which was actually the hangar and docking area for the larger sub-vessels. Mothership - Engineering Center
The drives of the Mothership were unusual, as indicated above. The Robotech Masters' scientists had perfected an efficient reactionless drive and installed this in each Mothership. However, as was proven over Earth, the shielding of this drive was not ideal, and the downing of the Robotech Master's flagship on Earth caused emergency modifications to the other ships of the fleet. In addition, the energy demands of this drive system far outstripped the generating capability of the class, even if all the internal space was to be converted into Reflex furnace chambers. Consequently, the ships stored a large amount of energy, built up over a long period of time, and discharged these into the drive units. The technological basis of this capacitator system is classified, but basic physics, and what information concerning this system is declassified, would suggest that the energy was stored in the form of anti-matter.
Technology and Combat CharacteristicsEdit
The armaments were impressive as well, with almost 200 Roil assault corvettes, tens of thousands of Bioroids, and a ship-to-ship armament second to none. The latter included a Reflex Cannon of the larger variety, numerous anti-ship cannons, and over a thousand anti-mecha cannons which proved to be frightfully effective against the Southern Cross's naval forces. Added to all this were the formidable passive defenses of the hull itself and the force-fields that came with it.
Internally, no two ships were completely identical, and only some broad layout details can be pointed out. The residential sections of the ship occupied the upper decks of the main hull, with the command and control sections underneath them. The lower parts of the hull were relegated to engines, storage sites and industrial purposes. The two horns on the underside formed the fold sensors, and the mentioned upper deck features were part research laboratory spaces and secondary command centers. As much of the internal hull could be restructured (originally for damage control purposes), any detailed description of the internal lay-out of any vessel must by necessity be placed within a certain timeframe. Outside said frame, the description would have become invalid due to the constants reshuffling and refitting done by the ships' commanding Triumviroid.
The Cityships started their lives as trans-light colony ships during the first colonization wave. In those times, fold technology was still primitive, and the fold drives of that time were all extremely large and inefficient. In addition, the total mass that could be folded was bound by an upper limit, and the colony ships were built right up to this limit. As much of the internal space and total mass of these vessels was reserved for the fold drives, their cargo capacity was far less than their size would lead one to expect. Later on, when more advanced fold engine designs became available, and protoculture power sources also became common, the colony ships were all mothballed, as they were utterly obsolete. However, they all had very substantial internal spaces, and because of Tirolian design practices, had very thick and sound hulls. Thus, when the Elders decided to emigrate from the Tirolian surface, they chose to strip the colony vessels of their gigantic fold drives, and use the freed-up space to install the latest in starship technologies. These new drives and other machinery were relatively so small, that the vessels all had large areas of free space left over, an extremely rare occurance onboard starships.
At this time, the Motherships were also equipped with the extremely heavy weapons suites discussed above. This later caused heavy casualties among the Army of the Southern Cross, when the Tirolians were forced to travel to Earth and do battle themselves over the last viable Protoculture Matrix. One Mothership was destroyed when a Tokugawa-class Battleship rammed and self-destructed inside her, while two other Robotech Masters cityships were destroyed when a Zor Prime, a clone of Zor, took out the main engineering computer. The force from the destruction of the main mothership over the Ruins of the SDF-1 helped spread the spores of the Flower of Life across the Earth. The rest of the ships either crash-landed to Earth after their protoculture reserves depleted or were brought down by earth forces.
