Long been exile from Earth for their actions againest mankind the NS-5 Robots had been living on the run from countless alien races who wanted their technology. The NS-5 robots had been safe so far within the boarders of a race called the united federation. Their leader, Sunny, had developed a new robot to upgrade and replenish their numbers that was in his image. his programing and mechanics was the key to their survival. Robot were far superior to humans begin that they could multi task better. they where physically stronger, faster and could identify targets, objects and surroundings within miliseconds. A race who particularly wanted their technology was the Geckodons, fortunately the Geckodons didn't want to put themselves in harms way to get it and put their faith in diplomacy.
The NS-5's were thankful, sure their technology was far superior in design and tactics, not to meantion their energy outputs could allow them to fire larger weapons more frequently. but their numbers where only 100,000. If the geckodons wanted this tech they could get it by force. the geckodons had a very large force, outnumbering them 1/10,000. this put the NS-5's at a disadvatage. so they continued to fly into space. no aim, not goal, nothing in their programing that could guide them exept their leader who clung to the hope of them finding their destiny.
Their ships had no fighter or anti fighter weapons... instead they developed a new weapon, somthing far deadlier than an entire fleet of fighters. they discovered the desgins from a planet still stuck in civil war. 2 factions, ZAFT and the earth forces. ZAFT's citizens where genetically enhanced superior to the naturals in everyway. but ZAFT's numbers where small. the naturals had large numbers.
They scanned and modified these new weapons. they are called...
these weapons originally ran on battery power but the NS-5's installed generators so they could last longer in combat.
No fighter, no matter how fast or agile it may be could ever match the irract combat patterns of a mobile suit. The lastest model was far superior to the original. It was code named, Gundam.
the gundam was conceived from the mobile suit Strike. the mobile suit was a trditional Space model, though further research reveiled that the Strike was possible made different than the other suit due to the fact it was made not just for space combat. but aerodynamic wings, implod and explode seals, balance centres. this thing could fight on planets aswell as space. the new Gundams where made similar except an upgrade in the power reserves. The strikes weakness was it's power issues. all the other mobiles suits could last an hour of combat, the strike could last on 30mins if it conserves energy. all the extra weapons armour and features drained massive power.
the other mobile suit types where specificaly made for certian area's of combat. the Gundams are primaraly for space. the Bakuu's where made for pure desert and ground assault.
Dog shaped made it easy for them to adapt to the slippery sand.
The Sub mobile suits are purely battle, collision checks and mass bombardment.
Ever the gundam where are match for a battlecruiser. a normal fighter wouldn't dream of going 1 on 1 with a giant ship but the gundams didn't just dream it, they did it, they could do it. which is why it makes them especially feared on the combat feild. which is also way everyone wanted to get their hands on the technology. little did they no it was impossible for them to use it anyways.
Mobile suits require milisecond like reactions, a pure knowleadge of how to use them (No second guessing the controls) and an understanding of the surrounding terran and enemies. those are the basic movemnet controls, combat is much harder. wepaons, energy, comencating for terran change or new events, split second programing skills, manual targeting systems, limb movement, repathing damaged systems and way more. which is why NS-5 could opperate it easily.
because the NS-5 had this weapons they had on need for 1 ship. A Mother ship. something to hold their mobile suits and citizens.
