Going ahead and labeling it "#1" since there's bound to be other size comparison's using the Yggdrasil to represent just how small my other ships are compared to it.

Left to Right/Diagnol: Yggdrasil Class Super Station, Rebel Missile Boat (no class name), and the Void Hammer Class Frigate.

The Void Hammer class and ships roughly its size would dock within the hangar on the lower prong of the forward section. Ships the size of the Rebel Missile Boat would dock in various one ship sized hangars along the Yggdrasil Classes side hangars. Ships of larger sizes would have to dock beneath the Yggdrasil class or run along side it and use shuttles to ferry crewmen and workers back and forth between each ships shuttle hangars.

The Top section just above and behind the top prong of the forward section houses the Yggdrasil Classes Fighter and Bomber hangars with ample room for shuttles and small cargo ships like the one I modeled for  management_9 .

I think thats all i got for now. Will need to accurately scale the Helios Class to the Yggdrasil, it'll likely be about the size of or a little bigger than the Rebel Missile Boat. I have yet to find anything to model in detail on the Yggdrasil (largest ship), will likely end up leaving it as is since I can't think of anything to detail.

Modeled in Google Sketchup 7.

Enjoy~
