Abstract
A submersible vehicle'"'"'s hull has an outer wall that is at least partially constructed of a multi-wall fabric having a sealed space between at least two walls thereof. The sealed space is controllably filled with one of air, water, and a combination of air and water in order to control the buoyancy of the hull formed from the multi-wall fabric. Means are provided for propelling and steering the hull in the water. The interior volume of the hull can remain dry or can be filled with water for a wet mode of operation.
