Extending our control over a battlefield requires additional height to encompass more of the elements that create control, i.e. increasing the field of regard, reducing the effect of topographical cover, and extending line of sight communications distances. The effectiveness of our forces involved in theater size conflicts can be utilized by the unmatched range, endurance, and altitude capability of High Altitude Long Endurance Unmanned Autonomous Vehicles (HALE UAV's). This recently demonstrated technology proved that a HALE UAV is essentially a geo-stationary, multi-use high altitude platform that has the advantages of both satellites and aircraft but not their inherent weaknesses.
