The invention as disclosed is a recoverable tethered optical fiber buoy
and winch assembly that is mounted to the back of the sail or the back of
an aft non-moving surface of an underwater vehicle and housed in a
configuration to provide very little additional drag to the underwater
vehicle when the assembly is not deployed. The invention provides a
capability to connect ocean surface visual or radio frequency sensors to
an underwater mobile platform with a very high data rate link that is
retrievable.
