The smaller GB/CB/1905 with 8-12in and 6in side armour

Applying David K. Brown's concept for what the smaller GB/CB/1905 should have been means that the speed drops to 33 knots. I had to lighten the machinery to use 1923 technology, to keep the Standard displacement at 25,000 tons of the original concept. This version has the 8-12in guns and 6in side armour that Mr. Brown told me would be best. Doing what D. K. Brown suggested actually makes the GB/CB/1905 a much more potent ship than what my friend Cliff was going to build. This is the Springsharp report:
