Abstract
A payload delivery unit for protecting and delivering a payload submerged in a submersion medium includes an unmanned buoy, a drop weight member, and a retention system. The buoy includes a container. The container includes a pressure-resistant shell defining a sealed containment chamber. The drop weight member is mounted on the shell and has a negative buoyancy with respect to the submersion medium. The retention system is operative to retain the drop weight member on the buoy and selectively release the drop weight member from the buoy.
