How closely can UAD reproduce a Tillman battleship?

How closely can the largest Tillman-style battleship be reproduced in UAD?

The available hulls and lack of sextuple turrets prevent a literal reconstruction; the attempt instead starts with fifteen 18-inch guns.

The request for the largest Tillman-style battleship first runs into UAD's available hull sizes. The game also lacks the sextuple turret needed for the suggested six-gun 16-inch mounting. A substitute arrangement is explored instead of reproducing that mounting. The resulting attempt begins with fifteen 18-inch guns, so it is a game adaptation of the maximum-battleship idea.
