text_A: Construction of the was started in 1936 and construction of an unnamed sister ship was started two years later in 1938, but neither ship was completed. In 1942 conversion of three German unfinished passenger ships ("Europa", "Potsdam", "Gneisenau") and two cruisers, the captured French light cruiser and the German heavy cruiser, to auxiliary carriers was begun. In November 1942 the conversion of the passenger ships was stopped because these ships were now seen as too slow for operations with the fleet. But conversion of one of these ships, the "Potsdam", to a training carrier was begun instead. In February 1943 all the work on carriers was halted because of the German failure during the Battle of the Barents Sea which convinced Hitler that big warships were useless.
