The 2001 version of the GB/CS/1914 design
I recast the GB/CS/1914 design as a 6in-gunned super destroyer. When I drew the ship in August 2001, I gave it a raised forecastle, three funnels, and lightly protected conning tower. The armament is 4-6in QF guns. The dimensions are 405ft x 41ft x 13ft. The speed is my standard 32 knots. I used direct drive turbines, as 1914 is early for geared turbines, although they are possible that early. This is the Springsharp report:
