U.S. law (Title 10 of the U.S. Code) directs each of the military services to organize, train and equip forces for combat so they are capable of winning wars, deterring aggression, and maintaining freedom. To achieve this level of readiness, the U.S. military must have access to airspace where they can develop and maintain skills for wartime missions and conduct research, development, test and evaluation of military systems. As such, appropriate airspace must be maintained and enhanced to accommodate necessary training and testing activities in support of national security objectives.
Recent world events have placed the U.S. military on heightened alert in the defense of the U.S. and allied nations. At this time, the U.S. military is actively engaged in anti-terrorism efforts around the globe.
