Well Syzmo and I worked a bit more on the Panzerschiffe proposal and here she is as she would have looked when in service in 1939 as the KMS Rheinland (drawing is still currently a WIP, will be updated);
Her construction had been altered after only the hull and basic superstructure had been completed. The hull remained in the slipyard for four months before it was decided to complete it to a 'Germanised' design for the Kreigsmarine. As the original plan had called for Sieran fitting the weapons after delivery, it was easy enough to install the more usual German secondary and Tertiary battery. The conning tower had only been partially completed but it was abandoned and replaced by a bridge design similar to the Deutschland class. Unlike those vessels, she was not modified with the newer 'atlantic bow' for fear her hull couldn't take the strain of the increased fore weight.
As stated in an earlier post, she was to see service during the Second World War in the Indian and Pacific oceans. After Germanys declaration of war upon the US, the ship sailed to Japan where she was transferred into IJN service but retaining her German crew. It was at about this time that she was taken into the shipyards at Kure for a refit, during which time she was fitted with a modified bow and superstructure, new radars and fire control systems, additional light AA weapons and numerous other alterations.
It was in this capacity that she saw some action against her intended users during 1942-1943. She was modified further during the course of the war by the Japanese but was sunk in harbour at Manila during a heavy US carrier raid. The ship was refloated but deemed unsuitable for the journey back to the Home Islands. At this time Japans war effort was flagging so the vessel was stripped of her guns and as much useful equipment before being scuttled as a breakwater just outside the harbour.
Her wreckage was scrapped in 1948.
