A mass production mobile armor created by the Earth Alliance, it is the Alliance's main space-use weapon during the early days of the war with ZAFT. Since beam weapons weren't invented when the Moebius series began production, its armament consists mainly of projectile weapons and missiles. The Moebius has a pair of vulcan guns built-in, and is often equipped with a linear gun as its main weapon. This gun is often flanked by four missiles, two on each side.
One feature of the Moebius is its ability to replace its standard armament, except for the vulcan guns, with other weapons if the mission required it. Such weapons include a gatling gun and an experimental beam cannon later on when beam weaponry was invented. The most powerful weapon a Moebius can mount is a nuclear missile. In terms of performance, the Moebius is surpassed by ZAFT's ZGMF-1017 GINN in almost every aspect except raw speed. It is stated that the average kill ratio of the Moebius against GINN is three to one (the Special Editions puts it as five to one), although it usually fares worse in real combat. Even when the Moebius is considered obsolete, they can be useful as support squads by utilizing their speed in "hit-and-run" attacks, as demonstrated in the manga Gundam SEED X Astray by the Ortygia squad.
Created before the Bloody Valentine War, the Moebius mobile armor was designed after the prototype TS-MA2mod.00 Moebius Zero and later became the main mobile weapon of the Earth Alliance for space combat. While in the beginning they were a swift and powerful weapon, they became obsolete when the ZGMF-1017 GINN is introduced by ZAFT. Until the introduction of Natural-pilotable mobile suits, the Moebius is the backbone of the Earth Alliance forces, despite its general inadequacy in combat against enemy mobile suits. Nevertheless it was a single Moebius unit which fired the nuclear missile that destroyed the PLANT colony Junius Seven, which triggered full scale war between the two forces.
The Moebius is phased out of frontline use by late June, CE 71, replaced by the GAT-01 Strike Dagger. Nevertheless, in November, at the Second Battle of Jachin Due, several squadrons are launched from the Earth Alliance's Agamemnon-class carriers for use as nuclear weapons delivery platforms. Most of these Moebius units are destroyed during the battle, along with the majority of the Alliance's Strike Dagger forces. Eventually Moebius units are replaced entirely by the Earth Alliance's mobile suit like the GAT-04 Windam, which could also be equipped with a nuclear missile launcher which carries twice as many missiles as the Moebius and still be effective in combat. However, the legacy of mass-produced mobile armors in the Earth Alliance is long from over with the introduction of the TS-MB1B Euclid during the later half of the Second Bloody Valentine War.
