Ok, here goes…
The first Death Star had a propulsion system that toted it around the galaxy to act as a means of coercion and destruction. Presumably, it had both shield generator AND armor and a fatal flaw that was incorporated into its design was exploited.
Death Star II was fully operational at the time of it’s assault by the Rebel Alliance. Presumably, armor in place with its shield generator, which was located on Endor. However, by that rationale, the second Death Star was entirely reliant on Endor for its shield capabilities. If not for its orbit around the moon, it was subject to destruction.
So…
Did the Empire have designs on building shield generators on every system under its control? Was there a similar propulsion system or was there one at all? If there was a propulsion system and only the one shield generator, were they going to tow Endor out of orbit of its home planet and drag it across the galaxy? Were they going to build multiple Death Stars, one for each system, and build shield generators for support in their respective systems? Or could the Rebellion truly have just avoided Endor altogether if they had wanted to?
As George Carlin would say, “These are the thoughts that kept me out of the really good schools.” Thanks in advance for any assistance on this mental anguish I have suffered these 3+ decades.
