The Forward Torpedo Room served as both a torpedo handling area and berthing area for 15 crewmen. The forward and after torpedo rooms were the preferred sleeping quarters because the rooms were quieter and cooler than the main crew berthing compartment amidships. The bunks were mounted in the spaces between the torpedoes.
The Mark 18 electric torpedo. 18 feet long, 21 inches in diameter, weighs approximately 3,000 pounds, and has a speed of 30 mph. The Mark 18 torpedo has a 600 pound warhead in the nose and can travel for a distance of approximately 2.5 miles.
The Forward Torpedo Room has six torpedo tubes. When leaving on war patrol the tubes are each loaded with a torpedo and the rest were stored on racks in the torpedo rooms allowing a total of 24 torpedoes.
