I'm still a total newbie at this game.
I think I'm just starting to get the hang of the ship designer.
These three ships are from my current game, my third game as the Yor and my 10th game of GalCiv2.
2 Corvettes and 1 fighter, I'm trying to keep all the ships looking somewhat similar so they look like they belong in the same fleet that said the 2nd Corvette is just a modified version of the first. Any helpful advice or criticism is very much appreciated!

Basic Fighter
Having no defenses this basic fighter was designed as fast-moving interceptor unit. It also sees use in a variety of misc. roles.

Defensive Corvette
This heavily armored corvette sacrifices speed for armor and firepower. It was designed to guard planets and star bases.

General/Offensive Corvette
This corvette is a modified version of the model A corvette. It sacrifices armor and firepower for speed. Still more heavily armored then the basic fighter and just as fast, this corvette is very flexible.

Next I've gotta design a medium sized ship to crush the upstart Altarians. I'm not really sure exactly how to go about doing this while still having it resemble the smaller fighter craft. Any ideas?
