In Star Wars Episode II, the roundels on the ships of the Galactic Republic have eight spikes. In Star Wars Episode 3, they have only six spikes. Why did the logo change? We can guess that cannot be due to the forming of the Empire because we can see six-spiked symbols early in the movie, while the Empire is only founded at the end.
Why did the insignia of the Republic change from eight to six spikes from Episode 2 to Episode 3?
