The original "Super Swift" design

I had to do bad things with the date that the machinery was built (to get a high enough power out per ton of weight), but I was able to pull off the Super Swift design mentioned in Volume I of Churchill's book The World Crisis. He described to Admiral Fisher two designs which caught Fisher's imagination: the Super Lion andthe Super Swift. I decided to try the Super Swift, as originally specified (6-4in guns and 37 knots, with no armor). Fisher wrote about the Super Lion, the Super Swift, the submarine, and aviation as being the future. The Super Swift was needed to be the eyes for the submarine. Anything else was a waste, in his view. I suspect that even with the late machinery date, Springsharp expects too much machinery volume for the SHP/ton achieved (48.58 SHP/ton).
