This view is looking aft in the After Torpedo Room on Torsk. Torpedo tubes 7 through 10 are located here, two to port and two to starboard. All are 21 inches in diameter. When leaving on patrol, four torpedoes would be carried loaded in the tubes, with six additional on racks.
Torpedoes were loaded into the torpedo room through an angled hatch in the overhead. There are controls on each tube that allow local firing of the torpedoes, in the event that the command could not be sent electrically from the Conning Tower.
