As others have noted before, this ship bears very little resemblance to the Ark we know from the cartoons and comics. The complete ship bears some resemblance to an Autobot shuttle in an overall manner, but still pretty far off, while the detatchable front end by itsef does seem to resemble the Ark we know fairly well. My thought is, what if the Ark we know, is not necessarily the complete package, but only the primary command sections of the ship? Or perhaps it is something akin to a scoutship or battle portion that could be detatched for recon or combat, leaving the main portion of the ship behind, safely out of harm's way, to allow for better maneuverability or range? This was the idea with the ST:TNG Enterprise being able to seperate the saucer from the rest of the ship. Perhaps it was even meant to be a landing craft, letting the primary ship sections stay in orbit to provide oversight, support, or just because landing the full bulk of the ship may not be necessary or feasible. The main section could even have been meant as an auxilliary part, for use mainly during extremely long noyages. Why then, did we only see this "combat saucer", you ask? Perhaps the ship was incomplete when it had to be launched. Or, perhaps the main section was in orbit, and they didn't have time to link up with it due to the attack. Maybe it just wasn't needed for the trip the Autobots thought they were going on. Also, if the bulk of the ship was not an integral part of the ark, that might explain why the stated crew compliment of 300 was never evidenced on Earth with that origin. 300 could be the compliment of the *complete* assembly, with the compliment of the Ark we know being much lower (as seems likely, from what we had seen of the Ark). Thoughts?
