The size of the USS Clarke - Malachowski Class

The USS Clarke NCC-1661 was a Malachowski class Federation starship operated by Starfleet during the mid-23rd century. It was destroyed in a battle against a Klingon fleet at the Battle of the Binary Stars in 2256.

The ship was named after the US Air Force pilot Nicole Malachowski, the first female member of the famed Thunderbirds acrobatic flying team.

• The premise for all my deck calculations: a deck is 2.5m + 0.5m for EPS cables, power cables, ... = 3m height for a deck. 
• My calculations follow a purely mathematical approach. I do not compare bridge modules or disk heights with each other. I always pull in decks based on the rows of windows and then calculate a physically plausible room height.

The ship has 11 decks.
After calculating the decks, this results in a length of 277.0m. The official size of the ship is correct.
