I was determined to drive the faster Fleet Cruiser at 37 knots
I realized that the term that I used for these two German light cruisers was "Fleet Cruisers", in that they were intended to scout for the battlefleet and work with destroyers. The faster of the two was longer and had only 6-6in guns and 8-23.6in TT. Like the other ship, there was only light armor patches. I was able to get 37 knots by inflating displacement horribly, and increasing the hull depth to get adequate strength. It is not economical, but I was not trying to be.
