ABSTRACT:
A submersible or submarine vessel having a unique pressure hull formed from a plurality of truncated spherical cells having at least one opening, wherein said cells are connected together in a generally loop array with said openings in confronting relation to define a interconnected internal space for utilization by personnel, equipment, or machinery. When said connected cells define a loop array having an open central area, dome means enclose the central area permitting utilization thereof, or, a further spherical cell or cells are disposed in the central area with access thereinto from a cell in the loop array for utilization, whereby at all times convexly curved spherical surfaces are exposed to high hydrostatic pressures, thereby to provide a maximum strength pressure hull.
