 Hindenburg 's primary armament was eight 30 @.@ 5 cm ( 12 in ) guns in four twin turrets , the same as in her two sisters . However , the gun turrets were Drh LC / 1913 mounts , which were an improved version the Drh LC / 1912 type mounts on Derfflinger and Lützow — the gun houses on Hindenburg allowed gun elevation to 16 ° , as opposed to 13 @.@ 5 ° in the earlier model . This gave the guns mounted in the Drh LC / 1913 turrets an advantage of some 2 @,@ 000 m ( 2 @,@ 200 yd ) over those in the older turret . Like her sister ship , the Lützow , she was armed with fourteen 15 cm ( 5 @.@ 9 in ) SK L / 45 guns and four 60 cm ( 23 @.@ 6 in ) torpedo tubes instead of the standard twelve 15 cm guns and four 50 cm ( 19 @.@ 7 in ) tubes mounted on Derfflinger . While 2 @.@ 5 m ( 8 @.@ 2 ft ) longer and 300 metric tons ( 300 long tons ; 330 short tons ) heavier than her sisters , Hindenburg was also faster , capable of steaming at 26 @.@ 6 knots ( 49 @.@ 3 km / h ; 30 @.@ 6 mph ) during trials , compared with 25 @.@ 5 knots ( 47 @.@ 2 km / h ; 29 @.@ 3 mph ) for Derfflinger .
