The "Improved" Ger/CB/1906 design

In 1973, I had made a more radical version of the Ger/CB/1906 design that depended on light-weight machinery and had a higher speed. In one place, I called for a speed of 34.2 knots, so I used that for this version. This is a photograph of one of the ships:

The ships are armed with 8-12in/45 BLR and 8-6in/50 QF guns. The belt is 4in, inclined at 17 degrees and the deck is 3in. The barbettes and turret faces are 8in. This is the Springsharp report:
