>>6323200>Star Wars has established military contractors who build these ships.So?
Look at how much things changed from Clone Wars era to ANH.
There was a complete shift in designs and even signs of them not knowing what they were doing (the wannabe star destroyers in AotC without weapons).
It's part of George Lucas' vision of a living breathing universe, where you can see them from movie to movie constantly changing.
Whereas Jar Jar Abrams just completely aped the designs from ANH (not even fucking RotJ) and basically did 1:1.3 equivalents.
Even our real life military equipment shows us learning from past designs to produce modern equipment, that looks completely different from one another.
The shift from F117 to B2 to F22 is less than 20 years for that to happen, and they all look different from one another. The shift from Blackbird to F117 is roughly 20 years. Again, a pretty big change.
It's something we saw in Luca's movies.
So no matter who made the designs, Jar Jar Abrams, like Lucas before him, was the one approving all the designs. So they may have shown him completely different designs and a real evolution of designs like the XWing, but he decided "boxy XWing good enough." Everything Jar Jar did was like he took the criticism from the prequels and did just the opposite, wholesale blanket. People said they hated the prequels, but loved characters/designs/etc, he said fuck off to Lucas' outlines that he did write and just copied the original trilogy crossing over the line of plagiarism because people loved the original trilogy.
