Abstract
A sonobuoy deployment system wherein a plurality of sonobuoy components are housed within a casing adapted to be dropped into the water, either from air or marine craft. The casing has a negative buoyancy, and houses a float deployment mechanism activated upon the casing entering the water. Actuation of the float deployment mechanism deforms a metal release plate previously holding a float within the casing, the float inflates, and as the casing sinks in the water the sonobuoy components are deployed from the casing upper end by cable connections attached to the float. Parachute structure may be mounted upon the release plate for automatic separation from the casing upon actuation of the float deployment mechanism. The utilization of a negatively buoyant casing, and deployment of the components from the casing upper end, permits the casing to quickly sink to significant depths, permitting the sonobuoy transducer components to be quickly located at the desired operating depth.
