Dutch Cruiser "B" take II

Well after some tinkering I have come up with a new line of cruisers which I believe satisfy the revised DRfG. So anyhow I’m posting for comments/criticism. I have not settled on what mix to build- straight 8,000 tonners, 8’s and 6’s or all of them.

The first is the DDL, the armor is merely meant to turn destroyer common rounds. For comparison, the same vessel sans belt and deck armor could make 36.25kts.

Second is the best 6,000 ton cruiser I could manage. It comes close to my 80-120mm belt/34 knot desire. It seems to be adequate in comparison to the India/Filipino forces, retaining the edge in speed.

Lastly are two 8,000 ton cruisers.
