THIS IMAGE IS A WORK IN PROGRESS!!!
As I've long ago completed the design for the Markovich class Battleships (still under construction at the time I rp, 1938), I decided to go back and design the predecessor class of vessels.
The idea behind these ships was for them to replace older ex-imperial Russian navy vessels still in service with ships that could potentially compete with any enemies that might contest Sieran's vital maritime trade routes, the most potential enemy being the Empire of Japan.
Sieran itself only has a few highly-skilled designers but foreign aid was brought in to design these vessels, the United States in particular thanks to favorable relations between the two.
The ships main operational area would be the Bering Strait and North Pacific ocean so the ships have strengthened hulls to deal with ice conditions and an experimental clipper style bow.
The only innovative feature of these ships is their turbo-electric drives which provide better throttle response and power to weight ratio whilst occupying smaller space.
Anyway, here is the stats generated in Springsharp which I think are okay.
