The underwater dive vehicle disclosed has a selectively energizable propulsion unit for forcible driving the vehicle through the water and at least one resilient gas filled buoyancy element which is in open contact with the surrounding water when the vehicle is in the water. The volume of the gas in the buoyancy element provides sufficient displacement of the water to keep the vehicle afloat at the surface when unattended or to support a diver. When the vehicle is submerged water pressure will act directly upon and tend to compress the resilient buoyancy...
[ What is claimed is:] [1.] An underwater dive vehicle comprising a selectively energizable propulsion unit for forcibly driving said vehicle through the water, buoyancy means including at least one flexible and resilient gas filled buoyancy element in open contact with the surrounding water when said vehicle is in the water, the buoyancy element being unvalved and completely and permanently sealed against the passage of gas therefrom or water there into, the volume of gas in said buoyancy element providing sufficient displacement of the water to provide...
