A submarine (1) has an assembly (3) for deploying a life raft (5) , the assembly (3) being located in a well (7) formed outside the submarine's pressure hull (11) . The assembly includes a pressure vessel (4) for storing the life raft (5) in a pressurized state. To deploy underwater, a lid (71) covering an opening to the well (7) is released to permit the assembly (3), which is buoyant, to ascend towards the water surface. A sensor (43) determines proximity to the water surface, whereby a pneumatic ram (42) in the pressure vessel is activated to eject the life raft (5) from the pressure vessel (4) .

Sous-marin (1) doté d~un ensemble (3) de déploiement d~un radeau de sauvetage (5), l~ensemble (3) étant placé dans une cavité (7) formée à l~extérieur de la coque de pression (11) du sous-marin. L~ensemble comporte un réservoir de pression (4) dans lequel est entreposé sous pression le radeau de sauvetage (5). Pour déployer le radeau de sauvetage (5) sous l~eau, un couvercle (71) recouvrant une ouverture de la cavité (7) est libéré pour permettre l~ascension de l~ensemble (3), flottant, vers la surface de l~eau. Un détecteur (43) détermine la proximité de la surface de l~eau de manière à activer un vérin pneumatique (42), monté dans le réservoir de pression (4), qui éjecte le radeau de sauvetage (5) du réservoir de pression (4).
