Thanks for the compliment, Borys.

I am convinced, too, that SS3 produces comparably light designs. The proposal above is basically lighter than a QE but faster, better protected and better armed. There must be something wrong, no doubt.
A more reasonable estimate would be 35 Kst. min. displacement. But even this would raise interesting questions with regard to the HOOD option. I personally believe that the Admiral class was not only worth it´s money but also an excellent balanced design, in many ways the king of all trades. I just wonder, how would the battlecruiser HMS HOOD have looked if not the Mackensen (8 x 35cm) but the D48 (6 x 38xm) would have been laid down with four units early in 1914 as originally planned. In such a condition we would likely see the british "R"-class as some kind of repeative QE´s (faster but lighter armored) already. Would the then designated "Mackensen" answer either a fast battleship like QE/R or resemble a more fisherized type like Repulse /Couragious?
Since the decision to build them might interfere with the laydown of Renown & Repulse, we would surely see an interesting scenario. No conclusive reports of the vulnarability of british BC in battle of Jutland would have been aviable by this time!
