An antenna extension system for extending an antenna from an underwater vehicle. The system comprises a housing disposed wholly within the vehicle and a plurality of telescopically connected tiers extendible from a base tier disposed within the housing, an innermost of the tiers being adapted to support the antenna. A cable extends from a base portion of the housing and is fixed at a distal end to the antenna. A plurality of telescopically connected fairings are extendible from the housing and are disposed around the tiers and the cable. A cap is fixed to a distal end of a distalmost of the fairings for enclosing the antenna. Extension of the telescopically connected tiers from the base tier moves the antenna from wholly inside the housing to a position extending outwardly from the vehicle, and extends the cable and fairings with the tiers.

Antenna extension system

A system for equalizing buoyancy of a submersible vehicle. The buoyancy elization system includes a submersible vehicle having a plurality of releasable objects. Ballast release means are positioned on the submersible vehicle, and a plurality of ballast vessels are joined to said submersible vehicle by the ballast release means. One ballast vessel is released upon release of one of said releasable objects in order to equalize buoyancy.

Submersible underwater vehicle ballast equalization system

A ballast weight system for releasably attaching a ballast weight to an urwater vehicle is disclosed where the system comprises a ballast weight, a housing disposed about the ballast weight, a fairing connected to the ballast weight to facilitate a flush connection of the ballast weight to the underwater vehicle, and a bolt coupler where one end of the bolt receives a lanyard pin therethrough and the second end connects a spring loaded bolt connected to the ballast weight. A linear actuator is connected to the lanyard pin. The lanyard pin placed through the bolt maintains the spring loaded bolt in spring compression such that when the pin is removed, the spring compression propels the ballast weight away from the housing.
