Here are the most of the meshes, that I have created for my Fan-Fiction SPACE 2064. (The German title for S:AAB was SPACE 2063 - but my FF starts in Dec. 2064.)
The last pic is a size comparison between three of the four capital Terran Spacevessels - the Frigate, that has a length of 204 Meters isn't on it.
The SA-43-X is a Version of the HAMMERHEAD, that I have created for my FF. In my Fanon the Engineers of AEROTECH has assimilated the weapons-tech of the Chigs (that they found in some Chig-Fighter-Wrecks) and build a Hammerhead-Fighter with 4 Plasma-Cannons.
The Laser-Turret on the back had to give way for it. In my Fanon the Firepower of this new Fighters is at 70 - 75 Percent of the Chig-Stealth-Fighter Firepower (without Rockets).
