Science and technology is traditionally divided into three broad categories: basic research, applied research, and advanced technology development. Basic research attempts to produce new knowledge in a scientific or technological area. This research is not associated with a specific weapon system. Applied research supports the development and maturation of new technologies for a defined military application. Advanced development entails large-scale hardware development and technology integration in more operationally realistic settings. Research and development beyond these categories is done in support of a specific weapon system. In the Air Force, the focal point for science and technology investments is the Air Force Research Laboratory. It was created in 1997 to centrally manage all Air Force science and technology efforts. Previously, the Air Force operated 13 different laboratories across the country. The present Air Force Research Laboratory, headquartered at Wright Patterson Air Force Base, comprises 10 technology directorates. Nine directorates handle applied and advanced development projects. The 10th directorate, the Office of Scientific Research, manages the Air Force's basic research projects. The Air Force Research Laboratory biennially generates a comprehensive strategic plan that supports the national military strategy and the Air Force Strategic Plan. In the past, the Air Force was a leader in high-technology exploration. According to a January 2000 Air Force Association study, the Air Force was the unquestioned leader in science and technology investments at the end of the Cold War. In the 1990s, however, it dropped to third place, behind the Army and Navy. The Congress has been concerned about the Air Force's level of investment in science and technology. For fiscal year 2000, the House and Senate Armed Services Committees noted that the Air Force in particular, had failed to comply with the science and technology funding objective specified in the prior year's authorization act, thus jeopardizing the stability of the technology base and increasing the risk of failure to maintain technological superiority in future weapons systems. In 2001, the Scientific Advisory Board found that the Air Force's science and technology program needed to improve its planning process and generate stronger user support and sponsorship. It also found weaknesses in the connection between operational requirements and science and technology programs, which inhibited the prioritization of investments. The Air Force complied with the overall requirements of the National Defense Authorization Act regarding long-term challenges. (See table 1 for the checklist of provisions.) The act defined a long-term challenge as a high-risk, high-payoff effort that will provide a focus for research in the next 20 to 50 years. To identify potential long-term challenges, an Air Force review team obtained over 140 ideas from a variety of sources in the scientific community. Ideas ranged from cloaking technologies (the deceptive masking of assets) and holodeck command capabilities (virtual reality battlespace control) to micro weapons like ubiquitous "battle bees" (miniaturized unmanned air vehicles) and cyber warfare technologies. The team evaluated these ideas to ensure that they complied with the three primary criteria specified in the act. The potential long-term challenges had to involve (1) compelling Air Force requirements; (2) high-risk, high- payoff areas of exploration; and (3) very difficult but achievable results. Yet another provision in the act required that the team should avoid selecting projects that are linear extensions of ongoing science and technology projects. This provision was more difficult to assess, but after additional deliberations, the team determined that the following six challenges satisfied the criteria in the act: Finding and Tracking. To provide the decision maker with target quality information from anywhere in near real-time. Command and Control. To assess, plan, and direct aerospace operations from anywhere or from multiple locations in near real-time. Controlled Effects. To create precise effects rapidly, with the ability to retarget quickly against complex target sets anywhere, anytime, for as long as required. Sanctuary. To protect our total force from natural and man-made hazards or threats, allowing us to operate anywhere with the lowest risk possible. Rapid Aerospace Response. To respond as quickly as necessary to support peacetime operations or crises and move this response to another location very rapidly if needed. Effective Aerospace Persistence. To sustain the flow of equipment and supplies as well as the application of force for as long as required. Once the long-term challenges were identified, the Air Force followed the planning process specified in the act. For example, it established six work groups tasked with identifying possible approaches to address these challenges. The groups had about 9 weeks to complete their work. As required, a technical coordinator, assisted by a management coordinator, headed each group. Each group also complied with the requirement to hold a workshop within the science and technology community to obtain suggestions on possible approaches and promising areas of research. The workshop participants satisfied the requirement to identify current work that addresses the challenge, deficiencies in current work, and promising areas of research. Finally, the groups were also expected to select projects that were not linear extensions of current science and technology work. This particular provision was not easy for some groups to define. Some pondered the relative nature of the term. For example, a user would perceive "nonlinearity" differently than a scientist. Another group characterized it as a quantum leap in capability. Another definition associated nonlinear projects with multiple-capability dimensions. For example, if doubling the payload capacity of a weapon is a linear extension, then doubling the payload, speed, and range of the weapon would also be a nonlinear extension. Regardless of the definition selected, each group addressed the issue in its planning process. Each group summarized the results of its workshop in a briefing that contained enabling capabilities, research areas, technology roadmaps, and associated funding requirements. In many cases, the level of funding projections was double or triple the level of the planned budget. For example, the level of funding projections for basic research in physics, materials, mathematics, and computer science was more than triple the planned investment levels. The Air Force complied with the overall provisions of the National Defense Authorization Act regarding short-term objectives. (See table 2 for the checklist of provisions.) As required, the Air Force established a task force consisting of representatives from the Air Force Chief of Staff and combatant commands to identify short-term objectives. The task force obtained about 58 ideas from the requirements, user, and acquisition communities as specified in the act. Because of the mandated short-term focus, most of the input involved enhancing or accelerating ongoing research efforts--not initiating entirely new areas of research. These ideas included maintaining aging aircraft, combat identification, and time-critical targeting. While these are not new concepts, they still present significant technological challenges. We have recently reported on weaknesses in each of these areas. The task force reviewed each idea to ensure that it complied with the criteria in the act: (1) to involve compelling Air Force requirements, (2) to have support within the user community, and (3) to likely attain the desired benefits within 5 years. To ensure that each idea represented a compelling Air Force requirement, the task force evaluated each idea against the Air Force's core competencies and critical future capabilities. To meet the user support requirement, the task force linked each potential short-term objective to specific mission needs and requirements documents. The objectives were reviewed and approved by the Air Force's corporate structure. To ensure that the projects selected would achieve results in 5 years, the task force decided to use the technology maturity levels highlighted in a recent GAO report. The following is a list of the eight short-term objectives. Target Location, Identification, and Track. To detect, locate, track, and identify air/ground targets anytime in countermeasure environments in near real time. Command, Control, Communication, Computers, and Intelligence. To dynamically assess, plan, and execute global missions. Precision Attack. To engage air and ground targets from manned and unmanned vehicles with the precision and speed necessary to bring about decisive results. Space Control. To increase the survivability of critical space assets. Access to Space. To improve access to space through responsive, cost- effective launch systems. Aircraft Survivability and Countermeasures. To improve the ability to survive and operate against airborne and ground threats in all environments. Sustaining Aging Systems. To extend the service life of aging aircraft and space launch systems with reduced manpower, reduced total ownership costs, and enhanced reliability. Air Expeditionary Forces Support. To provide air expeditionary forces with the ability to operate with highly responsive and agile combat support forces. After the objectives were identified, the Air Force complied with the planning process specified in the act. As required, it established an integrated product team to address each short-term objective. Each team was composed of a cross-cutting mix of officials from the requirements, user, and science and technology communities, as the act specified. According to many of the short-term objective team leaders, the cross- cutting nature of the teams was very productive. Not only did they believe that their planning was enhanced by the direct input from users and requirements officials, they also believed that the expertise and assistance from scientists in other laboratory directorates improved the process. Each team satisfied the requirement to identify, define, and prioritize the enabling capabilities necessary to meet the objectives. As required, each team identified the deficiencies in the enabling capabilities and projects necessary to eliminate the deficiencies. The teams summarized their work in briefings that contained prioritized lists of enabling capabilities, a definition of the objectives, technology roadmaps, and budget spreadsheets. The spreadsheets detailed the current and additional funding required to achieve the objectives. Obtaining the additional funding was a concern to many teams. Many teams identified funding requirements that greatly exceeded current funding levels; it was not uncommon for proposed annual funding levels to double or triple the level currently projected. For example, the Command, Control, Communication, Computer, and Intelligence team proposed programs that would require from 2.6 to over 4 times the planned annual investment. Another concern was the 15-year gap between the short-term objective and long-term challenge planning. According to the act's provisions, the short- term teams were required to focus on technologies that would be mature in 5 years; the long-term teams focused on technologies needed 20 to 50 years in the future. According to laboratory officials, this mid-term gap constitutes much of the normal science and technology planning effort and represents a critical point in science and technology project development. This time frame is where science and technology can have a significant impact. The Air Force currently addresses this time frame in its normal planning process. In addition, this period is covered in the long-term challenge technology roadmaps, at least for the research efforts associated with those six challenges. The Air Force satisfied the top-level review requirements in the act. (See table 3 for the checklist of provisions.) The act required the secretary of the Air Force to conduct a timely review of the science and technology programs and to assess the budgetary resources needed to address the long- and short-term needs. The secretary delegated this responsibility to the deputy assistant secretary for Science, Technology and Engineering. The deputy complied with the requirement to conduct a review of the long- and short-term science and technology programs within the 1 year time limit specified in the act. On October 25, 2001, the deputy briefed the secretary on the final results and received his approval. The act also required the secretary to assess the fiscal year 2001 budget resources used and needed to adequately address science and technology needs. After consultation with representatives from the House and Senate Armed Services Committees, however, the deputy changed the budget baseline to fiscal year 2002. This was done to reflect the science and technology budget realignment occurring in fiscal year 2002. The deputy assessed the 2002 budget resources planned for science and technology programs and determined that they were adequately funded. The deputy noted, however, that the current level of funding would enable the programs to pursue the minimum level of scientific research. Additional funding would be required to pursue other projects. The deputy also complied with the provision to evaluate whether the ongoing and projected science and technology programs addressed the long- and short-term science and technology needs. He determined that the programs did address these needs, thus obviating the requirement to develop a course of action for science and technology programs that do not address the long- term challenges or short-term objectives. Finally, the act required the secretary to review the long-term challenges and short-term objectives and to identify additional work that should be undertaken to meet the challenges and objectives. The deputy complied with both provisions. Not only did he review the results of the long- and short-term planning efforts and identify additional work, but he also directed that the additional work be incorporated into the laboratory's future planning, programming, and budget decisions. The deputy was in a unique position to address these requirements. He served not only as the overall review director for the science and technology planning process, but also as the chairman of the short-term objective task force. As a result, the deputy had many opportunities to review the work of both the long- term challenge and particularly the short-term objective planning teams. Because the Air Force complied with the provisions of the act, we are not making any recommendations in this report. The Department of Defense has reviewed this report and concurs with its contents. We conducted our work from May 2001 to January 2002 in compliance with generally accepted auditing standards. Additional information on our scope and methodology is located in appendix I.

Summary:
Congress and the scientific community are concerned that the Air Force's investment in science and technology may be too low to meet the challenges presented by new and emerging threats. The National Defense Authorization Act for Fiscal Year 2001 requires the Air Force to review its science and technology programs to assess the budgetary resources currently used and those needed to adequately address the challenges and objectives. GAO found that the Air Force complied with the requirements of section 252 of the act. The Air Force established an integrated product team to identify long-term science and technology challenges and a task force to identify short-term objectives. For each challenge or objective that was identified, the Air Force established teams to identify technological capabilities needed to achieve these goals. Each team chose research projects that addressed the criteria specified in the act. The Air Force also complied with the act's process provisions. The Deputy Assistant Director for Science, Technology and Engineering is required to review the teams' results and to identify any science and technology research not currently funded.
