An assembly for launching bodies from an underwater platform having a
pressure hull, and an outer hull subject to free flooding. The assembly
includes a module having a proximal end outboard of the pressure hull
portion of the platform, a distal end disposed proximate and in alignment
with a launch opening in the outer hull portion, and a chamber in the
module extending from the distal end of the module to proximate the
proximal end of the module, the module chamber being adapted to receive
and retain one of the bodies. Support structure on the platform retains
the module. A pump on the platform is in communication with water outside
the pressure hull, and an impulse tank on the platform is in communication
with the pump. A manifold is in communication with the impulse tank for
directing outflow of water from the impulse tank to the chamber to eject
the body from the chamber.
