Here is a suggestion for new ship part that would realy create new battle tactics.

this game lack carrier ship.

What I have in mind is a new thech branch.

Starfighter bay --> Repair bay --> construction bay --> Greater Starfighter bay

Starfighter Bay : Add a new ship modules : Launch bay.

Effect : All tiny ship in fleet add the speed of the carrier.

        : all tiny ship gain the range of the carrier

Repair bay : Add a repair module improving the repair rate of tiny ship

construction bay : Allow to build tiny ship inside a fleet as if you ad a single factory

Greater starfighter bay : Expand the bonus to small ship.

This would really give tiny ship a big role in the game.

new modules could only be implanted in a cargo, large and huge ship.
