Imperial Starfighters

The Imperial Empire's Starfighter Guidelines
The Empire's view on starfighters was centered on one main Idea. Believe it or not, that Idea was price.
 * Now Most people would think that the most powerful kingdom in the galaxy would have an unlimited budget. Fact is they do,but they were so focused on controlling the universe, they didn't think of the smaller problems, such as starfighter designs.

The age of TIE's
When the Empire was looking for a starfighter worthy of its cause they wandered onto a sienar fleet system design,and being as short minded as they were, only focussed on these things:size,manuverability,speed, maintenance, and most of all, cost. When they saw it cost less than 1,000 credits apiece,they put in an order for a few hundred thousand. It was just before that when they came up with a plan to use the starfighter to overwhelm the enemy with numbers, not firepower. And that is how the TIE/In Space Superiority starfighter was born.

The Evolution of the TIE
The TIE starfighters were first designed as a swarm fighter, and due to the overconfident Imperials, were completely sheild-less.This, of course, was hated by the outdated Tech. of rebelion starfighters, until deflector sheild system designs were perfected. Then the Rebellion saw the TIE's as one thing: an annoying parasite that was easy to vaporize.
 * Due to the rebellions wide use of the new X-wing starfighter, the Empire realised that due to the TIE's easily maintainable engine design, that new designs were needed for more specific roles, like bombers.
