 When the ships were reconstructed in 1934 – 36 , the remaining torpedo tubes and the two forward 14 @-@ centimeter guns were removed from the hull . All of the remaining 14 @-@ centimeter guns had their elevation increased to + 35 degrees which increased their range to 20 @,@ 000 meters ( 22 @,@ 000 yd ) . An unknown number of license @-@ built 13 @.@ 2 @-@ millimeter Hotchkiss machine guns in twin mounts were also added . The maximum range of these guns was 6 @,@ 500 meters ( 7 @,@ 100 yd ) , but the effective range against aircraft was 700 – 1 @,@ 500 meters ( 770 – 1 @,@ 640 yd ) . The cyclic rate was adjustable between 425 and 475 rounds per minute , but the need to change 30 @-@ round magazines reduced the effective rate to 250 rounds per minute .
