Note the H44 type was designed on the initiative of the navy in 1944 after Hitler had already become totally disillusioned with German surface fleet and had ordered all major surface units scrapped in 1943.H44 type for plan Z to rearm the German naval fleet and destroy the Royal Navy. I am convinced it was a real plan but Hitler was like a child. He had a short attention span and wanted quick results. Look at the battle of Britain the blitz worked the Luftwaffe had bleed the Royal Air Force white if it had kept up the English would have failed, but the Germans stopped they let off the pressure and turned back to Europe. After the Bismarck was sunk Hitler basicly locked up his own navy. Other then the u boats and commerce raiders the German navy was basicly a coast guard.
Hitler never rescinded the order to scrap the surface navy. He only agreed to a deferral in the execution of the order when Donitz argued that the scrap value of the fleet to the war economy wasn't worth the effort to scrap them.
