Torpedo launching tube and naval platform comprising at least one such tube

An ordinance-launching tube (1), of the type comprising a rear door (2) and an expulsion circuit (4) between a source of pressurized fluid (5) and the tube (1), and provided with means for closing this circuit that comprise actuating means (20, 21) that can be maneuvered by an operator in order to permit the expulsion, these actuating means being associated with means for detecting (23) the presence of the rear door (2) in the tube-closing position and with means for locking (26) this rear door (2) in the tube-closing position, which can be actuated via a bolt (24) that the operator can move between a first position preventing expulsion and a second position permitting expulsion when the door (2) is in the closing position and locked, wherein the bolt (24) comprises abutment means (27, 28, 29, 30, 31) that can be moved between a position blocking the actuating means (21) in position in order to prevent expulsion, and a position releasing these actuating means (21) so that they may be actuated by the operator, and thus permit expulsion.
