The August 2001 version of the GB/BB/1909 design

The GB/BB/1909 design has 9-12in/50 BLR and 8-6in QF guns. I assumed that the armor basis was 14in, and started with a 23-knot speed, although I increased the speed to 24 knots, since there was room to grow. The dimensions are 650ft x 100ft x 28ft, with a normal displacement of 29,000 tons. Since Springsharp allowed for growth in the design, I increased the range to 6,000 nm, as well as increasing the speed to 24 knots. I left the armored citadel lenght the same as the drawing, even though Springsharp complains that it is too short. This is the Srpingsharp report:
