This is always the problem with giving bad guys big, expensive, powerful gadgets. The bad guys are there to lose to the PCs, so inevitably there ends up being piles of big, expensive, powerful gadgets left lying around. With no owners.

Obi-Wan: The crew are abandoning ship.

Obi-Wan: Don't be ridiculous. It's too dangerous!
R2-D2: Oops. Looks like all the remaining escape pods just jettisoned mysteriously.
