Lyonesse Class Anti-Aircraft Cruiser.
These cruisers were designed and built to escort the large carriers Graf Zeppelin and Peter Strasser. Originally to have been a class of eight ships, cancellations and air-raid delays left only 2 ships that were completed in 1944. One uncompleted unit became a French war prize, the other undamaged hull was seized by the Russians.
By 1944 the German Radar systems had caught up to if not surpassed the Allied systems. The Lyonesse was completed with a full suite of radar for air and sea duties. The main armament was the same 5" twin that had been in service since 1935. The radar outfit slaved to these weapons made their accuracy phenomenal. For the first time a full set of 55mm Geraat Auto AA weapons were fitted to a German ship after trials on the Goeben. This was one of the main reasons the Lyonesse type were much bigger than the UK Dido and US Atlanta equivalents. The 55mm guns went through their ammunition at such a prodigious rate that huge magazine stowage of the endless belts was required.
This is the ship class the Germans needed at North Cape to blast through the British destroyer screen. These ships were destroyer killers.
(I have used an Austrian word for the class and it is also from a series of books by Jack Vance that I like, so while not strictly German it is of Germanic origin, much like Prinz Eugen.)
