Summary

I was a little annoyed with the Springfield class since it was quite complicated.
With @CaptainMojo his sets, I could easily fix that and therefore I give you the Illinois Class Starship (Springfield is the capitol of Illinois)

It has 14 decks, a HUGE shuttlebay

And measures 64 meters tall to the top of the nacelles, (49 to the dome on deck one)
271.27 meters long and has a width of 228.99 meters
making it more compact than a Galaxy by far.

(I prefer to measure the deck height at 3.5 meters including jeffreystubes)

Enjoy!
