Yep. She was notionally a replacement for the German predreadnoughts allowed Germany after WWI. The design was quite a remarkable one, because the Germans had to stay under 10,000 tons standard displacement, but still got a lot of speed, range, firepower, and armor into her using welding and diesel engines.
Not a very successful class, though. Too many mechanical problems and the light construction led to problems with the structure cracking in heavy seas.
Their best contribution to Germany's war effort was probably in forcing the allies to build ships designed specifically to match the Panzerschiffs, rather than building what the Allies really needed.
The best battleship design was unquestionably the Queen Elizabeth class of WWI, all of which survived into WWII, and one of which, Warspite, was the most successful, famous, and luckiest battleship in history. I also seem to recall Warspite steamed more wartime miles and saw more actions than any other battleship. She certainly has the record for most shells fired in naval combat.
