Abstract: A device for launching and recovering an underwater vehicle comprises a submersible assembly comprising a lower chassis and an upper chassis, which are connected by a flexible connection so that the distance between them is adjustable. The flexible connection and the lower and upper chassis form a receiving cage provided with an opening, whose vertical dimension can be adjusted. Moving the lower and upper chassis apart makes it possible to enlarge the vertical dimension of the opening. Moving the lower and upper chassis closer together makes it possible to support the underwater vehicle on the lower chassis and hold it in place using the upper chassis.

Abstract: A device for launching and recovering an underwater vehicle 20 comprises a submersible assembly comprising a lower chassis 24 and an upper chassis 25, the lower 24 and upper 25 chassis being connected by a flexible connection so that the distance between the said upper 25 and lower 24 chassis is adjustable. The flexible connection and the lower 24 and upper 25 chassis form a receiving cage 23 provided with an opening 28, the vertical dimension of which can be adjusted. Moving the lower 24 and upper 25 chassis apart makes it possible to enlarge the vertical dimension of the said opening 28 so that the underwater vehicle 20 can enter or leave the cage 23 without the movements of the cage 23 due to the heave impeding the entry or departure of the underwater vehicle 20.
