Abstract

A submarine detecting buoy has a container protecting the submersible portion having a hydrodynamic profile which assists the sinking of the weighted part of the assembly. The buoy is dropped by parachute (1) and the float (2) is detached at the surface of the water, while the sinker (3) protected by the sleeve (3') goes to the bottom. The float is inflatable upon contact with the water, the sinker descends until the support cable is fully unwound, and the casing leaves the buoy and sinks. The buoy then begins to transmit any acoustic signals to the radio transmitter in the float. The sleeve is made up of sections which are released by the action of springs.
