A more satisfactory high-speed scout

Springsharp let me achieve a better high-speed scout by going to a smaller displacement. That way, I was able to get a 38 knot maximum speed with a 15 knot cruising speed. The armament is 6-13cm DP guns, 8-57mm AA, and 12-40mm AA guns with 8-21in TT. There is no protection. This allows a better ship to be designed on a normal displacement of 3,450 tons. This is more of a super destroyer, which was what was intended, anyway. This is the Springsharp report:
