A comprehensive data base in blue-green propagation and devices developed at NOSC and elsewhere was used to evaluate the feasibility of a space- based laser strategic satellite-to-submarine communication system designed to broadcast to operationally significant ocean areas of the world. Although a major capability in submarine communication can be obtained by sequentially transmitting data at a moderate rate to small spots that span the total operational area, this capability can be realized only by the correction of major deficiencies in the current blue-green technology base. Dramatically better optical filters and much more efficient and powerful lasers must be developed before the technical risk of the concept is reduced to a satisfactory level. Also required are the resolution of major uncertainties in the transmission of optical energy through clouds and a reduction in the uncertainties associated with present oceanic and cloud climatology data bases. The overall objective of the program is to determine the practicality and suitability of an optical solution for transmitting strategic information to submerged submarines. This document describes the current program plan. It outlines the various system approaches being pursued, the technical uncertainty areas in both channel characterization and subsystem technology, and the investment strategy to be followed to meet the objective.
