This interior view of the forward torpedo compartment of the German U-Boat U-889 shows four torpedo tubes (centre) that were part of the submarine's primary armament.

Torpedoes posed the major threat to Allied vessels, although earlier in the war U-Boats also used deck guns against unescorted merchant ships. Two long rails (upper left and right) helped reload the torpedo tubes with the extra torpedoes stored in this compartment. Up to 25 crew members worked, slept and ate around the torpedoes and other equipment in this compartment.
