1. Type A ships will all be Federation ships, along with Type B ships.
2. Type C ships will probably be civilian ships using the Nisos color scheme. They will be designed to challenging, as they are freighters, transports, mining, or science ships.
3. The Federation fleet ship background will be used more often, since the only place I have seen it used in the vanilla game is at the entry to The Last Stand and at rare events in the Last stand. The Federation-Rebel fleet fighting background will be used more as well because why not.
4. Friendly ASBs will be used much more often, along with hostile ASBs
But now I've rambled, to the point of the actual mod. The goal is to make the game more about the Federation and the Rebels by increasing the amount of flavor for both. Also, it will have potentially lore-altering effects; it will also add new lore to both sides.

This is a Federation Dropship. They are used to drop soldier off at land battles, and are in times of peace used as freighters. - Credit to Justin17 for Textures

This is a Light Federation Fighter, the same design as the Rebel Fighters. They were mothballed after the Federation-Mantis war along with the riggers. - Credit to R4V3-0N for texture in the Shipyard

These are the same ships as the Rebel Riggers, but these have not been painted over and altered. They had mostly been mothballed after the Federation-Mantis war along with the light fighters.- Credit to R4V3-0N for texture in the Shipyard

This is a Federation Fighter. They are much more suited for fighting alone than Light fighters, and are much stronger. Unlike Light Fighters, they can have more systems and have not been adapted by the rebel fleet. - Recolor to Federation by StromblaaD, initial design as a rebel ship by Kieve.

This is a Federation Assault. They are heavy ships used for destroying small fleets and space stations. They were removed from service many years ago due to design flaws, but have since been reinstated into service due to the lack of ships. - Credit to JeffTheBoardingDrone

This is a civilian freighter. It is used by civilians to transport goods from place to place. They are mainly used by brave merchants or couriers nowadays, but some have joined up with the Federation or formed local militias to defend against the Rebels. - Image credit to R4V3-0N.
Sadly, because I am just figuring out how to mod this game, I can really only do ships, so it will probably take a while to get into beta or alpha version; contributions are welcome, and people who help will be credited.
