Technology & Combat Characteristics
The GNX-603T GN-X is an GN Drive Tau-equipped mass production mobile suit secretly developed in AD 2308 by Alejandro Corner, a United Nations ambassador and traitor of Celestial Being, whose true goal is to rule the world. It was developed based on the prototype GNX-509T Throne Varanus, which was in turn based on the Team Trinity's GNW-001~003 Gundam Thrones. Thus, the GN-X is also said to be based on the Gundam Thrones. Alejandro took great care to conceal the production of the GN-X – he contacted civilian factories across the world to make the mobile suit's parts and lied that they were for workloaders, these parts were then assembled into complete machines in secret factories within the Orbital Elevators. Thirty GN-Xs were produced in this manner and evenly distributed with their GN Drive Taus to the three major power blocs: AEU, HRL and Union.
Made to destroy Celestial Being, the GN-X was designed for battling the Gundams. Therefore, the GN-X's performance is slightly inferior to the Gundams' in certain situations, but with its excellent mobility, the ability to use beam weaponry, and independent flight capability all due to the GN Drive Tau, it is still much superior to the mobile suits used by the power blocs up till then. Additionally, since the GN-X's basic combat tactic is to rely on superior numbers to overwhelm the Gundams, it is not necessary to have performance that surpass those of the latter. Furthermore, the gap in performance can also be compensated through the use of formations during battles. There was a plan to equip the GN-X with the original GN Drive initially, and although this was later dropped, the specifications for installing the original GN Drive remained in the mobile suit's design. Owning to the cockpit's unique location, it is possible for the GN-X's pilot to survive even if the mobile suit's upper body is destroyed.
The GN-X's versatility and considerations for its pilots are also reflected in its weaponry: the close-range GN Beam Rifle can be converted into the GN Long Barrel Beam Rifle for long-range attacks, while its GN Shield incorporated the Defense Rod as the AEU and Union pilots are accustomed to such a defensive armament. During the battles against the Gundams, usable parts from destroyed GN-Xs were salvaged and assembled to create functional units.
Following the UN Forces' victory, the world moved towards unification and the dismantling of each nation's military began, but there were forces that resisted and the UN Forces deployed newly produced GN-Xs to take them down. The UN Forces also developed an ace pilot-use variant, the GNX-604T Advanced GN-X, and a successor unit, the GNX-607T GN-XII. However, mass production of the GN-X only started in AD 2311, when the UN transformed into the Earth Sphere Federation. It was suggested that the 3-year gap was because the UN needed time to analyze the technology of the GN-X and prepare the production lines.
History
The GN-X was developed in AD 2308 by the traitorous Celestial Being observer, Alejandro Corner, as part of his plan for world domination. 30 GN-Xs were secretly built under Alejandro's orders and his accomplice, Laguna Harvey, distributed these units and their GN Drive Taus to the three major power blocs. Units 1-10 were given to the AEU, units 11-20 were given to the HRL, and units 21-30 were given to the Union.===
After the UN Forces' victory, the world moved towards unification and the dismantling of each nation's military began. However, there were those that disagreed with this dismantling, including some of the mercenaries in Moralia. In response, the UN Forces deployed its GN-Xs to quell the mercenaries' rebellion. The mercenaries' mobile suits and the GN-Xs fought in the hilly regions, and the battles ended in the UN Forces' victory. The GN-Xs were also used to protect the Orbital Elevators from terrorist attacks, but the first line of defence seem to be the older, non-GN Drive Tau-type mobile suits, such as the MSJ-06II-AC Tieren Antiaircraft Cannon Type.
In Africa, despite the various measures UN took to support the region, some residents still harbored strong anti-UN sentiments and even took up arms against it. To battle the mobile suits deployed by the armed anti-UN group, the UN Forces launched its GN-Xs. In one such battle, one of the UN Forces' GN-X detected the cloaked GNY-002F Gundam Sadalsuud Type F that was observing the situation. The GN-X was about to attack Sadalsuud Type F, but was sliced in half by the GNY-001F2 Gundam Astraea Type F2 that suddenly appeared. Meanwhile, the battle between the anti-UN group and the UN Forces seem to have ended in the latter's victory, but some members of the anti-UN Group managed to escape.
Soon after the formation of the Earth Sphere Federation government in AD 2311, it was announced that the GN-X was to be mass-produced and formally adopted as the primary mobile suit of the Earth Sphere Federation Forces that would be officially established in a year's time. The first unit of this GN-X ESF Type was then unveiled to the public. However, the GN-X ESF Type was a short-lived machine as production soon shifted to newer GN-X series units.
