 During the modernization , four of her 15 cm guns were removed and two 8 @.@ 8 cm guns were added . All twelve 1 @-@ pounder guns were removed , as was the ship 's stern @-@ mounted torpedo tube . Kaiser Barbarossa 's superstructure was also cut down to reduce the ship 's tendency to roll excessively and her military masts were replaced with lighter pole masts . The ship 's funnels were also lengthened . Kaiser Barbarossa 's modernization was completed by 1 October 1907 , when she was recommissioned for service . By that time , the newest Deutschland @-@ class battleships were coming into service ; along with the Braunschweig @-@ class battleships , these provided enough modern battleships to create two full battle squadrons . Consequently , the Heimatflotte was renamed the Hochseeflotte ( High Seas Fleet ) . Kaiser Barbarossa returned to her place in the I Squadron and she participated in the normal routine of divisional , squadron , and fleet maneuvers and cruises without incident over the next year . The summer fleet cruise in May that year went to the Azores and returned to Kiel on 13 August . The autumn maneuvers lasted from 27 August to 7 September . Divisional exercises in the Baltic immediately followed from 7 to 13 September .
