 The torpedoes initially had a similar system where various rangefinders , especially the fifteen @-@ foot rangefinder above the aft torpedo control tower , and deflection sights provided data to a Dreyer table in the torpedo TS adjacent to the 5 @.@ 5 @-@ inch TS on the lower deck . However the Dreyer table was removed during Hood 's 1929 – 1931 refit and the calculations were made in the torpedo control position in the bridge .
