A version of the Ger/CB/1937 family of designs

I decided to try a larger size version of the Ger/CB/1937 family of designs. This version had dimensions of 864ft x 120ft x 32ft. I decided to use 16.5in guns, as they were not specified in the minimal specs that I had from early 1999. I went ahead and included a LAA armament to supplement what I had been using. The resulting ship seems to work quite well, although the displacement had to be much greater that I had forseen. This is the Springsharp 3.0b1 Beta report:
