This United States Air Force USAF manual, Air Force Doctrine Publication AFDP 3-52 Airspace Control December 2021, provides capabilities and procedures to increase operational effectiveness by promoting the safe, efficient, and flexible use of airspace. What worked in the past, will work in the future; but not in the same way! Airmen must be trained to perform deliberate planning of all-domain effects in a distributed or decentralized manner, and execute the mission when isolated from decision makers in distributed environments. Airmen at all levels must be comfortable making decisions and operating based on the commander's intent and the principles of mission command. This doctrine represents what we believe to be true based on the evidence to date. As we continue to press toward a more capable future force, it is critical that we continue to evolve our doctrine, ensuring a grounded foundation perpetually set to meet our nation's security challenges. Throughout our history, innovative Airmen have adapted technologies and developed methods of employment to meet the challenges our nation has faced. We will continue to do so.
