Conclusions
•Persistent systems are required to sustain ASW denial.
•Constant presence of detection systems was required to effectively sustain anti-submarine warfare for 30 days. Ability to achieve undersea control was dependent on employing systems that were persistent in both time and space.  Traditional methods used relatively small numbers of sensing platforms over large areas.  These assets were persistent in time, but due to their limited number were not persistent in space.  Non-traditional methods (such as rapidly deployed sensor grids and UUVs) proved to be persistent in space but without improvements in system recharging, tending and/or replacement they lacked the staying power of more traditional manned assets.
