Just as an FYI I took some final measurements of this thing and compared them to a Star Destroyer.
From what I found online a Star Destroyer is 1600 meters or 5200 feet long which is 80 feet short of a mile.
My Battle Carrier measures 2478 meters or 8131 feet long which is 1.54 miles.
It is 1560 feet tall by 3440 feet wide.
She is over 7 times the length of the new Gerald R Ford class aircraft carrier.

To quote Dr. Leonard McCoy in Star Trek 6 - "By God, that's a big ship."
