Right. What you are attempting is the S class destroyer, two of which were sold to Norway postwar. And I believe that Novice is already doing these, as part of his 'emergency war destroyers, and will soon do the S and T classes. Your difficulty is that you are designing a lot of your own stuff, whereas what you need are already existing stuff on the RN parts sheets plus existing drawings already done by Novice. Your guns are just not correct, and unless you get a high res drawing I can't see how this will stand up against what Novice will do anyway. I don't want to discourage you, but you'd best be aware that the S class will be done anyway.
