A torpedo-tube for use on model destroyers and battleships is shown in Fig. 104.
The submarine boat carries a number of torpedoes, and has one torpedo-tube near the forward end from which to fire the torpedoes.
The method of attaching the torpedo-tube to the deck is clearly illustrated in Fig. 104 and no further directions need be given.
The air-motor is started automatically by release of a trigger as the torpedo is blown out of the torpedo-tube.
The Dow torpedo-tube of the Maine has been located in the wreck.
