I have a book called Battleships of WWII It is a translation of a Russian book that was published 2005 called Linkory vtoroj mirovoj. In it the scharnhorst Is said to have been planned by Hitler to have the 283mm guns not to provoke GB and France BUT was studied to have 9 305 or 330mm guns or 6 380 350 or 330mm guns. And she became heavyer in building than planned 25000ton displacement (fully loaded 37000ton) and becouse of this it was a wery wet ship. So as early as 1936 the 380mm gun alternative was Ordered to be built and drawings to make the ship more seaworthy started but it was canselled at the outbrake of WWII.
