Nice...
Here's my advice:
1. Put ships on one page, weapons on another, missions on another... etc. This way even people with slower connections will be able to open pages fast (and it will look more organized).
2. Split the ships into classes - one page for capital ship, one for fighters, or go even further (cruisers/ destroyers/ carriers/....)
In time this database will get very big, so it's best to think on ahead.
3. You could allso put a special section for Truespace .cob or .scn files. That way people who started doing some ships (and stoped for various reasons) will be able to put them for download for someone else to finish.
