My Ger/BB/1907 design really worked well
Aside from having to inflate the displacement, I received a glowing report from Springsharp about my Ger/BB/1907 design. The concept was for a well-armored ship with 8-12in guns and 24 knots speed. I had hoped for a normal displacement of 25,847 tons, but that was too low for Springsharp. The ship has a tripod foremast and two funnels. What I was able to do was:
