 In 1903 , the fleet , which was composed of only one squadron of modern battleships , was reorganized as the " Active Battle Fleet . " Kaiser Barbarossa remained in the I Squadron along with her sister ships and the newest Wittelsbach @-@ class battleships , while the older Brandenburg @-@ class ships were placed in reserve in order to be rebuilt . The first quarter of 1903 followed the usual pattern of training exercises . The squadron went on a training cruise in the Baltic , followed by a voyage to Spain that lasted from 7 May to 10 June . The ship suffered some damage to her rudder , which necessitated temporary repairs at the Kaiserliche Werft ( Imperial Shipyard ) in Kiel from the end of July to 21 August . She thereafter took part in the autumn maneuvers and the winter cruise in the eastern Baltic and the Skagerrak . The autumn maneuvers consisted of a blockade exercise in the North Sea , a cruise of the entire fleet first to Norwegian waters and then to Kiel in early September , and finally a mock attack on Kiel . The exercises concluded on 12 September . The winter training cruise began on 23 November in the eastern Baltic and continued into the Skagerrak in early December . On 15 December , Kaiser Barbarossa was decommissioned for permanent repairs to her rudder , which lasted until January 1905 . She did not return to service , however , and instead began a major reconstruction .
