The ability of the United States Air Force (USAF) to keep its aircraft operating at an acceptable operational tempo, in wartime and in peacetime, has been important to the Air Force since its inception. This is a much larger issue for the Air Force today, having effectively been at war for 20 years, with its aircraft becoming increasingly more expensive to operate and maintain and with military budgets certain to further decrease. The enormously complex Air Force weapon system sustainment enterprise is currently constrained on many sides by laws, policies, regulations and procedures, relationships, and organizational issues emanating from Congress, the Department of Defense (DoD), and the Air Force itself. Against the back-drop of these stark realities, the Air Force requested the National Research Council (NRC) of the National Academies, under the auspices of the Air Force Studies Board to conduct and in-depth assessment of current and future Air Force weapon system sustainment initiatives and recommended future courses of action for consideration by the Air Force. Examination of the U.S. Air Force's Aircraft Sustainment Needs in the Future and Its Strategy to Meet Those Needs addresses the following topics: Assess current sustainment investments, infrastructure, and processes for adequacy in sustaining aging legacy systems and their support equipment. Determine if any modifications in policy are required and, if so, identify them and make recommendations for changes in Air Force regulations, policies, and strategies to accomplish the sustainment goals of the Air Force. Determine if any modifications in technology efforts are required and, if so, identify them and make recommendations regarding the technology efforts that should be pursued because they could make positive impacts on the sustainment of the current and future systems and equipment of the Air Force. Determine if the Air Logistics Centers have the necessary resources (funding, manpower, skill sets, and technologies) and are equipped and organized to sustain legacy systems and equipment and the Air Force of tomorrow. Identify and make recommendations regarding incorporating sustainability into future aircraft designs.

Many of the aircraft that form the backbone of the U.S. Air Force operational fleet are 25 years old or older. A few of these will be replaced with new aircraft, but many are expected to remain in service an additional 25 years or more. This book provides a strategy to address the technical needs and priorities associated with the Air Force's aging airframe structures. It includes a detailed summary of the structural status of the aging force, identification of key technical issues, recommendations for near-term engineering and management actions, and prioritized near-term and long-term research recommendations.

The average age of aircraft in the U.S. Air Force is 22, making aging an increasing concern. The Air Force program responsible for maintaining the structural safety of its aircraft faces challenges, however, such as budgetary pressures, regulations, and communication issues. The authors sought insights on these issues by comparing similar programs in other services. Their observations suggest the value of clear policies, independent assessments, standard metrics, and open and clear communication.

Modern software engineering practices, pioneered by the commercial software community, have begun transforming Department of Defense (DoD) software development, integration processes, and deployment cycles. DoD must further adopt and adapt these practices across the full defense software life cycle - and this adoption has implications for software maintenance and software sustainment across the U.S. defense community. Air Force Software Sustainment and Maintenance of Weapons Systems evaluates the current state of software sustainment within the U.S. Air Force and recommends changes to the software sustainment enterprise. This report assesses how software that is embedded within weapon platforms is currently sustained within the U.S. Air Force; identifies the unique requirements of software sustainment; develops and recommends a software sustainment work breakdown structure; and identifies the necessary personnel skill sets and core competencies for software sustainment.

The mission of the United States Army is to fight and win our nation's wars by providing prompt, sustained land dominance across the full range of military operations and spectrum of conflict in support of combatant commanders. Accomplishing this mission rests on the ability of the Army to equip and move its forces to the battle and sustain them while they are engaged. Logistics provides the backbone for Army combat operations. Without fuel, ammunition, rations, and other supplies, the Army would grind to a halt. The U.S. military must be prepared to fight anywhere on the globe and, in an era of coalition warfare, to logistically support its allies. While aircraft can move large amounts of supplies, the vast majority must be carried on ocean going vessels and unloaded at ports that may be at a great distance from the battlefield. As the wars in Afghanistan and Iraq have shown, the costs of convoying vast quantities of supplies is tallied not only in economic terms but also in terms of lives lost in the movement of the materiel. As the ability of potential enemies to interdict movement to the battlefield and interdict movements in the battlespace increases, the challenge of logistics grows even larger. No matter how the nature of battle develops, logistics will remain a key factor. Force Multiplying Technologies for Logistics Support to Military Operations explores Army logistics in a global, complex environment that includes the increasing use of antiaccess and area-denial tactics and technologies by potential adversaries. This report describes new technologies and systems that would reduce the demand for logistics and meet the demand at the point of need, make maintenance more efficient, improve inter- and intratheater mobility, and improve near-real-time, in-transit visibility. Force Multiplying Technologies also explores options for the Army to operate with the other services and improve its support of Special Operations Forces. This report provides a logistics-centric research and development investment strategy and illustrative examples of how improved logistics could look in the future.

The Air Force has several options for sustaining weapon systems and components but has, in recent years, increasingly chosen contractor logistics support (CLS) over organic support. Still, questions remain about costs and efficiency, even about whether CLS is the best option. The authors explored these by reviewing the relevant government and DoD documents and data and by speaking with various knowledgeable individuals. The authors noted that CLS contracts have often gone to original equipment manufacturers because, lacking the technical data, the Air Force could not choose a third party. They also noted that contracts that guarantee large annual sums limit the Air Force's ability to adjust when its own funding changes and that the reasons underpinning these decisions are not always complete or consistent across the service. Centralizing and standardizing data and the related management skills would help make them available across the Air Force. More important, to retain all its choices for logistics services throughout a system's life cycle, the Air Force should acquire the technical data or data rights near the start of the acquisition process.
