A new thread: American battleships

This starts a new design thread. Again, the thread starts in 1914. This time, the ship is an American battleship design: US/BB/1914. I must confess to being throughly conventional. I had thought of only having a 9-14in gun main armament, but I went with 12-14in, instead. The result seemed pretty reasonable. This is the Springsharp report:
