Welcome aboard savmagoett. Interesting 1st post there.

For the sake of 'bay size' comparisons etc., here's another look at Adywan's new version -

....and how ROTJ's shuttle exit from the smaller front 'bay' looks -

As far as when we come to 'ROTJ:Revisited', Adywan has indicated that Vader's shuttle may instead seem to have exited from his Executor ship rather than 'some other' Stardestroyer, so we may not see the above shots in their current form anyway....

I'm curious, are all the Stardestroyers seen in ANH, ESB, and ROTJ meant to be exactly the same size?

I'm sure the more analytical of us can do better than I, but my guess is that it depends on what class they are.

Are the SDs in the OT mostly Imperial or ImpII Class? Or are there some bigger/smaller ones excluding the SSDs?

Nvmd, sniped by Ady. :P
