 As was customary on capital ships of the period , the Bayern @-@ class ships were armed with five 60 cm ( 24 in ) submerged torpedo tubes . One tube was mounted in the bow and two on each broadside . A total of 20 torpedoes were carried per ship . However , both Bayern and Baden struck mines in 1917 ; the damage incurred revealed structural weaknesses caused by the torpedo tubes ; both ships had their lateral tubes removed . The torpedoes were the H8 type , which were 8 meters ( 26 ft 3 in ) long and carried a 210 kg ( 463 lb ) Hexanite warhead . The torpedoes had a range of 6 @,@ 000 m ( 6 @,@ 550 yd ) when set at a speed of 36 knots ; at a reduced speed of 30 knots , the range increased significantly to 14 @,@ 000 m ( 15 @,@ 310 yd ) .
