Since the early 1980s, the Air Force has been working to modernize and consolidate its space command and control systems and improve its space situational awareness. Effective command and control systems are important because DOD space capabilities are globally distributed and operated from geographically diverse locations. With new threats against space assets, the ability to quickly respond or take action can mean the difference between mission success and failure. Space situational awareness is the current and predictive knowledge and characterization of space objects and the operational environment upon which space operations depend. Good space situational awareness data are the foundation of command and control systems because the data are critical for planning, operating, and protecting space assets and informing government and military operations. The Air Force’s last three space command and control programs over more than three decades have ended significantly over budget and schedule, and key capabilities have gone undelivered. Those programs were the Cheyenne Mountain Upgrade, the Combatant Commanders’ Integrated Command and Control System, and the Joint Space Operations Center Mission System. Some capabilities were deferred from one program to the next, making the true cost growth in each program significantly higher when compared to original program content. This deferral was due in part to the complicated nature of the planned work. Enabling a single system to command and control numerous assets in space and on the ground at multiple levels of information classification is a technically challenging task. In addition, as discussed below, we found that the Air Force made optimistic cost and schedule estimates for these programs, and thus did not assign adequate resources to their development. Begun in 1981, the Cheyenne Mountain Upgrade was intended to modernize systems that provide critical strategic surveillance and attack warning and assessment information. We issued 11 reports on the Cheyenne Mountain Upgrade program between 1988 and 1994. In 1991, we found that the program planned to complete only a portion of its requirements in an attempt to stay within budget and schedule constraints. We also found that the Air Force had adopted a strategy of deferring some requirements on the optimistic assumption that these requirements could be achieved during later stages of system development. We concluded that while such deferrals may have permitted the Air Force to meet revised short-term goals, they also masked the magnitude of problems the program experienced as it moved forward. We also found that DOD had not formally evaluated the performance risks related to deferring requirements and concluded that the strategy of deferral significantly raised the risk that system development would be more costly and take longer. DOD declared the program operational in 1998; however, some critical capabilities were not delivered. At that time, the program was nearly $1 billion over budget and 11 years late. That same year, DOD determined that some of the program’s components were not well integrated and would be unresponsive to future mission needs. DOD initiated the Combatant Commanders’ Integrated Command and Control System program in 2000 to modernize and integrate the Cheyenne Mountain Upgrade computer systems and to replace a space situational awareness data computer system called the Space Defense Operations Center (SPADOC). At that time, the SPADOC system was significantly overtaxed and in need of replacement by a system that could handle larger volumes of data. In 2006, we found that Combatant Commanders’ Integrated Command and Control System program costs had increased by approximately $240 million, 51 percent over initial estimates, and the program was at least 3 years behind schedule. In addition, we found that that some capabilities had been deferred indefinitely, resulting in increased risks to performing future operations. Further, we found that the Air Force did not effectively assess the appropriateness of the program’s requirements prior to initiating the program, leading to significant additions, deletions, and modifications to the program’s initial requirements. Consequently—similar to what transpired within the Cheyenne Mountain Upgrade program—significant amounts of work were deferred to address the cost increases associated with requirements changes. Ultimately, the Combatant Commanders’ Integrated Command and Control System program was not able to successfully replace SPADOC. Started in 2009, the Joint Space Operations Center Mission System (JMS) was the Air Force’s most recent effort to meet command and control capability and space situational awareness data needs and replace the SPADOC system. JMS was a software-intensive system and was supposed to be delivered in three increments. Increment 1 was to provide the foundational structure for the overall program. Increment 2 was to deliver numerous operational capabilities to users, including replacing SPADOC by the end of fiscal year 2014 with the ability to automatically determine if objects in space were likely to collide (called conjunction assessments), which was a key performance parameter for the program. Increment 3 was to provide additional command and control capabilities and the ability to incorporate data from highly classified special access programs. Of the three planned increments, Increment 1 is the only one that is fully operational today. JMS Increment 2 encountered significant challenges during development, and in 2016 the program experienced a critical change because of significant schedule delays and cost increases. Specifically, JMS Increment 2 planned to delay delivery by more than 1 year, in turn increasing total program costs by over 25 percent. According to the August 2016 JMS Critical Change Report, which the program office submitted to Congress in September 2016 as a result of the critical change, several issues contributed to Increment 2’s challenges. These included an overly aggressive schedule, inadequate staffing, underestimating the amount of work required to integrate various pieces of the system that were developed by different groups, and numerous concurrent development efforts. An independent program assessment team comprised of military, intelligence, and contractor staff determined that the JMS program had underestimated the complexity of developing the system. Further, the program reported that its organizational structure proved problematic. For example, the program reported that program- related contracts were awarded and administered outside the program office, which limited program flexibility and support and hampered effective oversight. As a result of the critical change, the program re- estimated its costs, established new schedule goals, and deferred a number of capabilities and requirements to Increment 3. Even after these changes, JMS Increment 2 was not successful at delivering its planned capabilities. Air Force operational testing in 2018 revealed significant issues with JMS Increment 2 performance. The Air Force’s test team determined that Increment 2 was not suitable for operations, as it was unable to provide conjunction assessments or maintain the catalog of space objects, another key performance parameter. In the wake of these findings and the numerous issues found in testing, the Air Force stopped further development on JMS Increment 2. When development ended, JMS was almost 3 years behind schedule and $139 million (42 percent) over budget. Air Force leadership placed the JMS Increment 2 program in sustainment and transferred three of the 12 planned Increment 2 capabilities into operations; the remaining nine capabilities were to be used for planning and analytic purposes only, as they were not reliable enough for operational use. Key requirements from Increment 2, including automated conjunction assessments and the ability to maintain a high-accuracy space catalog, as well as all of the requirements from Increment 3, were deferred to a subsequent effort, called the Space C2 program. Because JMS was unable to replace SPADOC, the system is still in use today. Since 2000, the Air Force has been addressing unique space surveillance requirements for follow-on systems to SPADOC. Air Force officials we spoke with stated that the system’s ability to continue operations is a growing concern. While work is underway to move SPADOC onto a more modernized platform and infrastructure, the Air Force has not established a schedule for that effort. In the meantime, Air Force officials told us that large amounts of data are going unprocessed as the volume of available sensor data today is greater than ever before—and is expected to increase exponentially in the next year as new DOD sensors come online. The Space C2 program is the Air Force’s latest software-intensive program to develop capabilities to anticipate and respond to emerging threats in space and ensure the uninterrupted availability of capabilities to the warfighter. SPADOC is expected to be retired as Space C2 capabilities become operational. The Air Force expects to spend between $72 million and $108 million per year on the Space C2 program, which is managed by the Air Force’s Space and Missile Systems Center, through fiscal year 2024. While it is still early in the planning and development stages, the Air Force’s Space C2 program office expects to deliver a consolidated space command and control system over the next few years using a new system design. The program also plans to use a modernized, iterative software development process called Agile development to more quickly and responsively provide capability to users. According to Air Force officials, this development approach is relatively new to DOD programs. Therefore, the Space C2 program and DOD officials are working to determine the appropriate level of detail needed for the program’s planning documents as well as the best way to provide oversight of a non-traditional development approach. The Space C2 program is intended to consolidate operational level command and control capabilities for DOD space assets into an integrated system, allowing operators and decision makers to have a single point of access to command and control space assets around the globe in a timely manner. A consolidated space command and control capability will: allow operators to comprehensively identify and monitor threats to identify possible courses of action to mitigate or eliminate threats, communicate courses of action to decision makers, and direct action to respond to threats. A consolidated space command and control capability is necessary, according to Air Force and DOD officials we met with, because the space domain has transitioned from a benign environment to one that—like ground, sea, and air domains—is contested by foreign adversaries. According to these officials, DOD needs the ability to respond to the increased threats to U.S. space assets in near real-time. Consequently, the Air Force is planning for Space C2 program capabilities to be significantly more automated than in the past, requiring high-quality software development and architecture planning. As shown in figure 1, the Space C2 program itself will consist of multiple layers. Program officials explained that the foundational layer is the computing infrastructure, which must be secure from vulnerabilities and have adequate processing power to accommodate the complexity of the system. On this infrastructure will run the software platform, which forms the backbone of the operating system. The Space C2 program plans to procure the platform commercially. The software platform will contain standards that developers will need to comply with to create applications that will work on the platform. Some applications may be targeted to a broad number of users, and some may be more niche capabilities for a particular group of users. Space C2 program officials told us they believe this structure will allow them to be flexible in meeting multiple user needs more responsively than has been possible in past DOD programs. Users include, for example, space system operators responsible for predicting and avoiding space object collisions, and other operators responsible for responding to conflicts in space. The program also expects applications from a variety of developers, both commercial and government, to run on the platform, thus presenting opportunities for companies that do not regularly do business with DOD to participate in the program. The work being done for the Space C2 program is spread out among multiple Air Force groups. For example, the Air Force Research Laboratory has been developing applications for the Space C2 program both internally and with commercial partners since 2016. The Laboratory is also working on some battlespace awareness capabilities that may eventually run on the Space C2 program’s platform. Additionally, officials from the Air Force Rapid Capabilities Office stated that they have been working on common interface standards for applications, and this work will feed into the Space C2 program. As the Enterprise Manager, the Space C2 program manager is responsible for integrating all of the development work selected for use in the Space C2 program, irrespective of its origin. A principal component of the Space C2 program is a data repository that will be populated with data from a wide variety of commercial, civil, military, and intelligence space sensors. Eventually the program plans for operators using the Space C2 program’s platform and applications to be able to retrieve data from the data repository. The data will be electronically tagged with its appropriate classification level and will be accessible to users according to their individual security clearances. The overall design of the Space C2 program is for data to be gathered from sensors, placed into the data repository, and then be available for various applications to process and provide timely information to space operators and commanders on threats to space assets and anomalies in the space environment. Operators and commanders will then be able to promptly direct actions, such as tasking sensors to collect additional data or respond to threats. Figure 2 shows the proposed construct of the Space C2 program, including the various actions that can be taken in response to the data collected by the sensors. The Space C2 program is planning to use an approach new to DOD in terms of software development, known as Agile. Agile development is a flexible, iterative way of developing software that delivers working capabilities to users earlier than the traditional, incremental DOD software development processes, known as the waterfall approach. Agile practices integrate planning, design, development, and testing into an iterative life cycle to deliver software early and often, such as every 60-90 days. The frequent iterations of Agile development are intended to effectively measure progress, reduce technical and programmatic risk, and be responsive to feedback from stakeholders and users. This is different from the way DOD has developed software in the past, in which requirements were solidified in advance of development and the software was delivered as a single completed program at the end of the development cycle—with no continual involvement or feedback from users or ability to modify requirements. Traditional software development mirrored the development of a hardware system. We have previously reported on past DOD software programs that experienced challenges due, in part, to that traditional development approach. The differences between the two approaches are illustrated in figure 3. The Space C2 program is one of the first DOD software-intensive programs to move away from the traditional approach and into the more modernized Agile development methodology. Program officials told us that many of the problems with JMS’s development stemmed from its more traditional approach, and that with the Space C2 program they wanted to avoid circumstances that did not lead to program success. Considering that past software development problems were caused, at least in part, by the traditional method of software development, utilizing a different approach could be a positive step. However, the current DOD acquisition instruction does not include guidance for Agile software programs. According to DOD officials, new software guidance is in development, and this guidance is expected to offer pathways for developing Agile programs. DOD has also developed a draft template to assist Agile programs with developing their acquisition strategies, though the template and associated software guidance are in the early stages of development. In the meantime, however, Space C2 program officials confirmed that they are currently operating without specific software acquisition guidance. Space C2 officials also clarified that while official Agile software acquisition guidance has not yet been formally published, the program office has been actively engaged with the Office of the Under Secretary of Defense for Acquisition and Sustainment on refining draft policy and guidance. The program office noted that its program activities over the past year have been informed by and are consistent with this draft guidance. The Space C2 program has submitted preliminary planning documents to the Under Secretary of Defense for Acquisition and Sustainment for approval. While officials in the Under Secretary’s office expect these documents to be modified and expanded upon in late 2019, the Under Secretary gave the program approval to begin its development under an Agile process, signifying her support for using alternative approaches. In addition, Air Force officials told us that the Commander of Air Force Space Command has requested frequent briefings on the program’s development process, and while he does not have approval authority over the program, he is monitoring the program closely. Plans show that the program is conducting 90-day development iterations with the goal of providing working software at the end of each cycle. As of August 2019, the program had completed three program development iterations, and reported delivering capabilities which included: expanding the commercial data available in the data repository; tasking various sensors; and providing a tool for visualization and analytics. The Air Force noted that these capabilities were deployed in a relatively short time; however, most capabilities delivered so far are considered to be available for use “at your own risk,” since they have not yet been fully approved for use in operations. Though the Air Force has not yet published a time frame for certifying these capabilities for operational use, the new development approach is underway and delivering some early capabilities. DOD officials noted that the foundational elements of the Space C2 system, including the infrastructure and software platform, should be completed prior to significant application development; however, at this early stage of the program, the schedule indicating the time frame in which these elements will be completed appears to be still in development. For government programs, some level of insight and oversight is essential when using public funds to develop a system. According to DOD officials, DOD is embracing Agile development because software can be delivered quickly and can be more responsive to user needs. However, according to GAO’s upcoming guide for assessing Agile development programs, known as the Agile Assessment Guide, sound engineering principles are still beneficial when employing this approach. For example, continuous attention to technical excellence and good design requires the developers to consider security requirements throughout development. This is particularly true with complex programs that process sensitive data with complex security requirements. In past work, we have found that teams overlooking security requirements may end up developing systems that do not comply with current federal requirements (for example cybersecurity requirements for information technology programs), resulting in the software not becoming operational until these components are addressed. In addition, the Agile Assessment Guide notes that transitioning to Agile software development can be challenging because Agile methods require organizations to do more than implement new tools, practices, or processes. Agile requires a re-evaluation of existing organizational structures, planning practices, business and program governance, and business measures, in addition to technical practices and tools. However, Agile does not mean eliminating the need for documentation, planning, oversight, architecture, risk analysis, or baseline schedule, for example. Leading practices for Agile software development—as described in GAO’s upcoming Agile Assessment Guide—state that, among other things, programs should have the following characteristics: a product owner who manages the requirements prioritization, communicates operational concepts, and provides continual feedback to the development team; staff who are appropriately trained in Agile methods; management that has established an Agile supportive environment; a program strategy that reflects the mission, architectural, safety- critical components, and dependencies; organization’s acquisition policy and guidance that require the contract type and the acquisition strategy to be aligned to support Agile implementation; an architecture that is planned upfront to enable flexibility and to provide support to Agile methods; and mission goals that drive the prioritization of the most advantageous requirements (e.g., security and privacy) that are well understood and reviewed throughout development. Recognizing the need to change traditional processes to accommodate more iterative software development, both the Air Force and Under Secretary of Defense for Acquisition and Sustainment have created software advisor positions. The Air Force Chief Software Officer and the Special Assistant for Software Acquisition are working to improve and modernize the way DOD acquires software. In addition, DOD is looking into how to use industry practices to modernize the way it develops software. For example, the Office of the Secretary of Defense has a Development Security Operations (DevSecOps) pathfinder program for software, which helps programs define and develop a technical digital roadmap and leverages industry and Office of the Secretary of Defense expertise in developing appropriate infrastructure for software programs. The DevSecOps concept emphasizes rapid prototyping, security, and continuous integration and delivery of software products. In a May 2019 Acquisition Decision Memorandum, the Under Secretary of Defense for Acquisition and Sustainment directed the Space C2 program to become a pathfinder program. This is a positive step, because it should increase input into the program’s acquisition planning by the Office of the Secretary of Defense software development experts. The Office of the Secretary of Defense has other groups that draw on private-sector software development expertise to help DOD programs, including the Defense Digital Service and the Defense Innovation Board. These groups’ missions include improving DOD’s technology and innovation, and the groups can be valuable DOD resources for helping the Space C2 program develop its plans and Agile processes. The Defense Innovation Board conducted a review of some of the Space C2 program’s software acquisition plans in December 2018. According to the Office of the Secretary of Defense officials we spoke with, this informal review was beneficial and resulted in real-time feedback on the approach the program was taking, as well as suggestions for areas to focus on. In the May 2019 memorandum, the Under Secretary of Defense for Acquisition and Sustainment noted that in October 2019 she will determine if an independent technical assessment of the Space C2 program is necessary. Considering the stated benefits of the prior Defense Innovation Board review of the Space C2 program, as well as the fact that using Agile processes for a DOD program is relatively new and includes many unknowns, independent reviews could help ensure the program is on a successful path. As the Office of the Secretary of Defense and the Air Force have made an effort to increase in-house Agile software development expertise, programs like the Space C2 program—especially in light of its early stage of development—could benefit from periodic attention from the experts at its disposal, including input from independent, external reviews to help ensure the necessary software development steps are taken to set programs up for success. DOD programs following traditional acquisition processes conduct internal reviews at major milestones, and GAO best practices for knowledge-based acquisitions also include conducting independent program reviews at these milestones. The draft GAO Agile Assessment Guide notes that while traditional DOD program milestone reviews are not used for Agile programs, Agile programs rely on other review methods such as stakeholder demonstrations and retrospective program reviews during each iteration of work. In addition, the GAO Schedule Assessment Guide, which identifies best practices for managing a program’s schedule, states that programs should conduct periodic reevaluations of risks, and that an independent view in this is valuable. Such reviews offer greater objectivity, as the reviewers are not responsible for the activities being evaluated, and programs benefit from the wide variety of expertise and experience represented by the external review team. In addition, in many cases, having these external reviews periodically can prove useful. The Space C2 program faces a number of management, technical, and workforce challenges. Some of these challenges may ultimately be overcome by time and experience, and the Air Force has efforts underway to mitigate others in the near-term. But it is too early to determine whether these efforts will be sufficient to achieve program success. The Space C2 program faces several management challenges. The Air Force has been working on developing various parts of the Space C2 program since 2016, but as previously noted, the program is working from a draft acquisition strategy and does not yet have an overall program architecture. These plans are important for providing direction for a program and facilitating effective oversight by establishing a business case for the effort. A business case establishes that the program is necessary and that it can be developed with the resources available, and typically includes: a requirements document, an acquisition strategy, sound cost estimates based on independent assessments, and a realistic assessment of risks, including those relating to technology and schedule. In addition, according to Air Force officials, the Space C2 Enterprise Manager has management responsibility—but not authority—over multiple development efforts included in the Space C2 enterprise. For example, technology maturation and risk reduction activities are divided across three program offices, managed by two program executive officers, and reliant upon multiple sources of information. This division of work is being done in part because the various organizations have areas of expertise that the program was hoping to leverage. However, such distribution of activities among many organizations can result in synchronization and coordination challenges. JMS’s development was hampered by similarly-split responsibilities for development contracts for various efforts. Because space is becoming an increasingly contested domain, DOD has noted that its ability to effectively respond to space threats has increased the importance of focused leadership in national security space, to include Space C2. See table 1 for additional details of management challenges facing the Space C2 program. According to officials from the Space C2 program and the Office of the Secretary of Defense, the Space C2 program was allowed to begin development work without an acquisition strategy, due to the program’s urgency. In May 2019, the Under Secretary of Defense for Acquisition and Sustainment tasked the Space C2 program office with revising its preliminary acquisition strategy to be consistent with DOD’s draft template for software acquisition. DOD’s draft template contains specific elements for ongoing planning and evaluation that are to be included in DOD software acquisition strategies moving forward, including acquisition and contracting approach; program management structure, including authorities and oversight plans for platform and infrastructure development; requirements management and development approach, and plans for prioritization; risk management plans, including how the program will identify and mitigate risks; metrics for measuring quality of software, and how those results will be shared with external stakeholders; manpower assessment identifying program workforce needs and state of expertise in Agile methods; requirements for reporting program progress to decision makers; and yearly funding levels. We have also noted these factors in our previous reports that identify the need to develop a sound, executable business case at the outset of a program, and the importance of using knowledge-based decision making in DOD acquisition programs. In addition, our work on best practices for knowledge-based acquisitions has emphasized that the success of any effort to develop a new product hinges on having the right knowledge at the right time, and that a better opportunity exists to meet program goals when the knowledge is available early. However, given that DOD’s draft template is still subject to change, including these elements in the finalized acquisition strategy would help position the program for success. The Space C2 program also faces significant technical challenges, as described in table 2. For example, the program is planning to meet previously deferred requirements that proved too complex for prior programs to achieve. It also plans to address new and emerging threats to space assets, for which requirements are not yet defined. In addition, the program plans to use an Agile software development approach, the processes of which DOD has yet to show proficiency in applying, as discussed above. Integration of the multiple types of software planned for Space C2 is also likely to present considerable technical challenges. Further, cybersecurity is a growing concern for DOD space programs, including Space C2. In addition to the management and technical risks we identified, limited availability of staff with expertise in Agile software development poses a challenge to the Space C2 program and to DOD in general. The Space C2 program manager stated that the program is undertaking an effort that is fast-paced in nature and needs to be rapidly fielded, and she expressed confidence in her staff’s abilities to meet the development demands. However, various DOD officials told us that a lack of qualified software developers within DOD, and within the Space C2 program, is an issue. Agile software development methods are different from the traditional approaches used by DOD, and according to DOD officials, proficiency in Agile methods requires specific training. Software developers with this training are in high demand in the private sector, and according to DOD officials, sufficient numbers may not be immediately available for the Space C2 program. One industry best practice for software development states that to be successful, programs should ensure that each development team has immediate access to people with specialized skills including contracting, architecture, database administration, development, quality assurance, operations (if applicable), information security, risk analysis, and business systems analysis. As early as March 2009, DOD acknowledged it had a top priority to establish a cadre of trained information technology professionals, and that the lack thereof was a significant impediment to successful implementation of any future software development process. Furthermore, a 2018 Defense Science Board report highlights the lack of Agile software expertise in DOD, citing no modern software expertise in program offices or the broader acquisition workforce. Moreover, the report states that DOD defense prime contractors need to build their own internal competencies in modern software methodologies. Similarly, we found in March 2019 that DOD faces several challenges related to hiring, assigning, and retaining qualified personnel to work on space acquisition programs, similar to the challenges it faces more generally with the acquisition workforce. We also noted that DOD is taking steps to address these challenges where possible. In May 2019, the DOD’s Defense Innovation Board issued a congressionally mandated study on software acquisition and practices. The report stated that numerous past studies have recognized the deficiencies in software acquisition and practices within DOD. The report also noted the importance of digital talent and stated that DOD’s current personnel processes and culture will not allow its military and civilian software capabilities to grow fast or deep enough to meet its mission needs. In addition, the report stated that new mechanisms are needed for attracting, educating, retaining, and promoting digital talent and for supporting the workforce to follow modern practices, including developing software in close coordination with users. Finally, the report emphasized that the military services and Office of the Secretary of Defense will need to create new paths for digital talent (especially internal DOD talent) by establishing software development as a high-visibility, high-priority career track and increasing the level of understanding of modern software within the acquisition workforce. This is the case for all DOD space programs, including Space C2. DOD’s ability to command and control U.S. space assets, as well as anticipate and respond to the threats these assets face, is critical. However, over more than three decades, DOD’s efforts to improve its space command and control capabilities—commensurate with the space threats that have continued to grow in frequency and type—have been fraught with development problems. The Air Force has again undertaken a program to meet the nation’s ongoing and future consolidated command and control needs, while trying to overcome past problems with a modern software development process. The Space C2 program is making a concerted effort to learn from past software development mistakes while forging a new path for Agile development. Though DOD is taking steps to ensure that the Space C2 program has a comprehensive approach in place for managing, identifying, and mitigating challenges associated with this approach, key program plans and agency-wide guidance are still in draft form, leaving uncertainty as to how program development and oversight will ultimately proceed. Finalizing a robust acquisition strategy containing the key elements for ongoing planning and evaluation would position the program for success. Striking the right balance between trying new development methods and working within DOD’s knowledge-based framework will be essential for meeting cost, schedule, and performance goals. Periodic assessments of the program’s approach to developing software, done by independent software development experts, could not only help ensure the reviews are balanced, but would also help ensure the Space C2 program effectively addresses the challenges it faces and is situated for success. Such reviews would also help the Space C2 program to identify potential roadblocks, and ultimately, potential solutions. Effectively addressing the challenges facing the Space C2 program will help ensure that needed space command and control capabilities are no longer deferred, but actually delivered. We are making two recommendations to the Department of Defense. The Under Secretary of Defense for Acquisition and Sustainment should ensure that the Air Force’s finalized Space C2 program’s acquisition strategy includes, at a minimum, the following elements: acquisition and contracting approach; program management structure, including authorities and oversight plans for platform and infrastructure development; requirements management and development approach, and plans for prioritization; risk management plans, including how the program will identify and mitigate risks; metrics for measuring quality of software, and how those results will be shared with external stakeholders; manpower assessment identifying program workforce needs and state of expertise in Agile methods; requirements for reporting program progress to decision makers; and yearly funding levels. (Recommendation 1) The Under Secretary of Defense for Acquisition and Sustainment should ensure that the Air Force’s Space C2 program conducts periodic independent reviews to assess the program’s approach to developing software and provide, as needed, advice to the program and recommendations for improving the program’s development and progress. Participants could include, but are not limited to, officials from the Defense Innovation Board, the Defense Digital Service, the office of the Air Force Chief Software Advisor, and the Under Secretary of Defense for Acquisition and Sustainment’s Special Assistant for Software Acquisition. (Recommendation 2) We provided a draft of this product to the Department of Defense for comment. In its comments, reproduced in appendix II, DOD concurred with our recommendations. DOD also provided technical comments, which we incorporated as appropriate. We are sending copies of this report to the appropriate congressional committees, the Secretary of Defense, the Secretary of the Air Force, and the Under Secretary of Defense for Acquisition and Sustainment. In addition, the report will be available at no charge on GAO’s website at http://www.gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-4841 or ChaplainC@gao.gov. Contact points for our Offices of Congressional Relations and Public Affairs may be found on the last page of this report. GAO staff who made major contributions to this report are listed in appendix III. The House Armed Services Committee report accompanying a bill for the National Defense Authorization Act for Fiscal Year 2018 contained a provision for us to review the Department of Defense’s (DOD) efforts to develop space command and control capabilities. This report (1) assesses the status of and plans for ongoing Air Force efforts to develop advanced command and control capabilities for space, and (2) identifies challenges the Air Force faces in developing these capabilities. To assess the status of and plans for ongoing Air Force efforts to develop advanced command and control capabilities for space, we analyzed Air Force Space Command and Control (C2) Program Increment Demonstration and Planning Retrospective reports for the first three increments and examined acquisition strategies for relevant programs, including acquisition strategies and addenda for Joint Space Operations center (JSPOC) Mission System (JMS) Increments 1 and 2. We also examined the Air Force’s draft acquisition strategy for Space C2 and DOD’s draft acquisition strategy for Major Agile Software Programs; reviewed Space C2 document mapping planned capabilities to the specific requirements that will be met by program deliveries; and analyzed status updates from the Space C2 program and the Combined Space Operations Center and program update briefings prepared for congressional staff by the JMS and Space C2 programs and the National Space Defense Center. In addition, we analyzed Space C2 program plans in conjunction with interim DOD guidance for Agile Software Acquisition, the Joint Chiefs of Staff Cyber Survivability Endorsement Implementation Guide, the Office of the Secretary of Defense guidance on cybersecurity operational test and evaluation procedures in acquisition programs and DOD Enterprise Development, Security and Operations (DevSecOps) processes; and examined the Principal DOD Space Advisor’s Capabilities Based Assessment which included issues relating to Space C2. We also reviewed Air Force Broad Agency Announcements and Requests for Information for Space Battle Management Command and Control and Space Situational Awareness capability development. In addition, we obtained information from 12 of the 16 companies with whom the Air Force is working to obtain their perspectives of the Air Force’s approach to developing Space C2 capabilities. To identify challenges the Air Force faces as it develops advanced command and control capabilities for space, we analyzed the JMS Critical Change Certification; examined Joint Requirements Oversight Council memoranda pertaining to the JMS critical change management and certification; reviewed the Air Force’s Space and Missile Systems Center evaluation of commercial capability gaps and capabilities; reviewed the JMS Program Manager briefing on lessons learned; and examined the DOD test and evaluation report on JMS Increment 2 (Service Pack 9). We also reviewed a selected chapter of GAO’s draft Agile Assessment Guide (Version 13), which is intended to establish a consistent framework based on best practices that can be used across the federal government for developing, implementing, managing, and evaluating agencies’ information technology investments that rely on Agile methods. To develop this guide, GAO worked closely with Agile experts in the public and private sector; some chapters of the guide are considered more mature because they have been reviewed by the expert panel. We reviewed this chapter to ensure that our expectations for how the Air Force should apply best practices for development of software capabilities for space command and control are appropriate for an Agile program and are consistent with the draft guidance that is under development, and we compared Space C2 program plans to the practices outlined in the guide. Additionally, since Agile development programs may use different terminology to describe their software development processes, the Agile terms used in this report are specific to the Space C2 program. We also compared Air Force development plans with interim and established DOD guidelines for software development, and GAO best practices for knowledge-based decision-making in weapons system development. We also reviewed prior GAO reports on the Cheyenne Mountain Upgrade, the Combatant Commanders’ Integrated Command and Control System, software acquisition, and cybersecurity. Additionally, we interviewed DOD officials from the Office of the Under Secretary of Defense for Acquisition and Sustainment; Joint Chiefs of Staff, Force Structure, Resources, and Assessment Directorate; U.S. Strategic Command; Air Force Combined Space Operations Center; Defense Advanced Research Projects Agency; Missile Defense Agency; Office of the former Principal DOD Space Advisor; Air Force Space Command; Air Force Research Laboratory; Defense Digital Service; Office of Cost Assessment and Program Evaluation; Air Force Rapid Capabilities Office; National Space Defense Center; and Air Force Space and Missile Systems Center. Finally, we interviewed officials from commercial companies that are known in the space community to have potential input into the development of space command and control capabilities to understand how the Space C2 program plans to integrate commercial capabilities into the program. We conducted this performance audit from January 2018 to October 2019 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives.

Summary: Since the early 1980s, the Air Force has been working to modernize and consolidate its space command and control systems into a single comprehensive platform. The past three programs to attempt this have ended up significantly behind schedule and over budget. They also left key capabilities undelivered, meeting the easier requirements first and deferring more difficult work to subsequent programs. At the same time, the need for a consolidated space command and control capability has been growing. The House Armed Services Committee report accompanying a bill for the National Defense Authorization Act for Fiscal Year 2018 contained a provision for GAO to review DOD's newest efforts to develop space command and control capabilities. This report describes the status of these efforts and identifies challenges the Air Force faces in bringing them to fruition. To conduct this work, GAO analyzed acquisition and strategy documentation, management directives, and lessons learned; and compared Air Force development plans with leading industry practices for software development, DOD guidelines, and best practices included in a draft GAO guide for assessing Agile software development programs. Given emerging and evolving threats in the space domain, as well as significant development problems in similar prior efforts, the Air Force is prioritizing the Space Command and Control (C2) program. Early prototype work on the program's software began in 2016. As of mid-2019, the program had delivered some initial capabilities; however, the capabilities delivered so far are not approved for use in operations. Because the program is still early in development, it has not yet established a time frame for certifying these capabilities for operational use. Further, the foundational elements of the program, including the infrastructure and software platform, are still being conceptualized. All Space C2 program capabilities will be significantly more automated than past development efforts and are being designed to allow operators to identify and monitor threats to U.S. space assets, identify courses of action to mitigate or eliminate those threats, communicate these actions to decision makers, and direct actions in response. To develop Space C2's technologically complex software, the Air Force is following a modernized, iterative process called Agile development—a relatively new approach for Department of Defense (DOD) programs (see figure). The Space C2 program is facing a number of challenges and unknowns, from management issues to technical complexity. Additionally, DOD officials have not yet determined what level of detail is appropriate for acquisition planning documentation for Agile software programs. They are also not certain about the best way to provide oversight of these programs but are considering using assessments by external experts. These knowledge gaps run counter to DOD and industry best practices for acquisition and put the program at risk of not meeting mission objectives. Additionally, software integration and cybersecurity challenges exist, further complicating program development. The Air Force has efforts underway to mitigate some of these challenges in the near term, but until the program develops a comprehensive acquisition strategy to more formally plan the program, it is too early to determine whether these efforts will help to ensure long-term program success. GAO is making two recommendations, including that DOD should ensure the Air Force develops a comprehensive acquisition strategy for the Space C2 program. DOD concurred with the recommendations.
