I like (thematically) the idea of internal starfighter hangars, but I was under the impression that wasn't the case for this vessel. As I mentioned, I also seem to recall this being a flip-flopping point of contention in the past.
Any ideas why the adventure appears to disagree with the AoR Core Rulebook (which specifically mentions the TIEs mounted externally along the spar)?
Is the justification that the Rebels and the Imperials prefer different configurations an insufficient answer?
Sure. It could be an answer, but I don't think the "evidence" agrees.
I don't actually care about this tidbit as much as this thread implies, but....
I take the "...externally along the spar" comment to be an indication of the lack of internal hangar space. Or at least an indication from the CRB writers that they aren't sure about where the TIEs are supposed to go.
I realize that my inferences drawn from such a minor sentence fragment are not entirely justifiable, but dragging externally mounted ships through hyperspace seems less "ideal" than carrying them inside a protected (environmentally controlled) hangar space.
Why? TIE repairs or refits while the Neb-B is underway, for one. Any ships larger than this don't carry their TIEs that way, so I am led to believe it is not the optimal or preferred carriage method.
Carrying ships externally could likely shave a few seconds off launch times, but such a piggy-backing arrangement seems an unnecessarily inconvenient arrangement if you had the option for internal hangars (fitted with TIE racks).
Good points about the scale of models used in filming. We likely can't "learn" all that much from a careful study, frame-by-frame, of movie props. I am convinced George Lucas doesn't care as much about this subject as we appear to (and I think that is true across the width and breadth of the Star Wars universe). He is/was looking to make a cool Space Opera story, not build a fully-formed alternate reality of hard Sci-Fi. The fact that the Star Wars canon almost works this way is incredibly remarkable.
As another side note, the CR90 that supposedly has been retrofitted to carry starfighters has additional "pods" installed that fill in the empty space between the engineering section aft and the hammerhead bow, if I recall correctly.
