Unmanned Aerial Systems: Air Force and Army Should Improve Strategic Human Capital Planning for Pilot Workforces
Highlights
What GAO Found
The Air Force and the Army have not fully applied four of the five key principles for effective strategic human capital planning for managing pilots of unmanned aerial systems (UAS) that are important for resolving the Air Force's pilot shortages and the Army's training shortfalls (see table below). Consistent with the first principle, the Air Force involved top senior leaders, UAS pilots, and stakeholders to develop a plan to resolve its UAS pilot shortages—including reassigning UAS workload to Air National Guard units and supporting training and operations with contractors. The Air Force partially applied the second principle to tailor its strategy to address gaps, or shortages, in UAS pilots, such as by using temporary personnel. As of March 2016, 37 percent of the personnel filling UAS pilot positions are temporarily assigned manned-aircraft pilots. Air Force headquarters personnel stated that no other career field in the Air Force relies on temporarily assigned personnel to this extent. Without tailoring its strategy to provide more permanently assigned pilots, the Air Force risks losing the experience that temporarily assigned manned-aircraft pilots have acquired. The Army partially applied the second principle because its strategy is not fully tailored to address its shortages in unit training. The Army experienced training shortfalls—61 of 73 UAS units flew fewer than half of the 340-flight-hour per unit annual minimum training goal in fiscal year 2015. A Senior Army official acknowledged the continued training shortfalls was a concern for the Army. Without revising its strategy to address the remaining training shortfalls, the Army risks that its UAS units may continue to train at levels below Army goals.

The Air Force and the Army have not evaluated their workforce mix—that is the mix of military, federal civilian, and private sector contractor personnel—to determine the extent to which these personnel sources could be used to fly UAS. Furthermore, although neither the Air Force nor the Army have evaluated how and to what extent federal civilians could be used as UAS pilots, both services are using private sector contractors to fly some UAS. Without evaluating their workforce mix, the Air Force and the Army do not have information on alternatives for meeting UAS pilot personnel requirements to meet mission needs. In addition, although the Air Force and the Army decided to use private sector contractors to meet mission needs, they did not conduct cost analyses to inform this decision. Without such an analysis, the Air Force and the Army may not be using the most cost-effective workforces to achieve UAS missions.
Why GAO Did This Study
The demand for UAS combat operation support has grown dramatically in the last decade. Since 2008, the Air Force has more than quadrupled its requirements for UAS pilots but faced challenges meeting the requirements due to UAS pilot shortages. Meanwhile, a 2015 Army review found that Army UAS units' mishap rate was higher than for other aircraft and Army officials stated that training shortfalls had contributed to the mishaps.
Senate Report 114-49 included a provision that GAO review Air Force and Army UAS personnel strategies. GAO assesses the extent to which the Air Force and the Army have (1) applied key principles of effective strategic human capital planning for managing UAS pilots and (2) evaluated the workforce mix to meet UAS pilot requirements. GAO compared its previously developed key principles of effective strategic human capital planning with Air Force and Army actions. GAO analyzed data on required and actual Air Force UAS pilots and data on Army UAS training.
Recommendations
GAO's 11 recommendations include that the Air Force tailor its strategy to address UAS pilot shortages; the Army revise its strategy to address UAS training shortfalls; and that both services evaluate their workforce mix for UAS pilot positions and conduct analysis to ensure cost effectiveness of workforce decisions. DOD concurred with 2 recommendations and partially concurred with 9, noting actions that it believed addressed the intent of GAO's recommendations. GAO continues to believe that DOD needs to take actions to fully address the recommendations.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Department of Defense | To help the Air Force in its effort to address UAS pilot shortfalls, and to help ensure that the Air Force strategies to address UAS pilot shortages are tailored to address remaining issues, such as the significant amount of pilots who are temporarily assigned to the UAS pilot career, the limited amount of cadet interest in the UAS pilot career, and the workload of UAS pilots, the Secretary of Defense should direct the Secretary of the Air Force to revise the Get Well Plan to address these issues. | The Air Force did not revise its Get Well plan but has addressed the issues we reported or those issues no longer pose problems for the Air Force UAS career field. In particular, the Air Force no longer staffs manned pilots temporarily to serve as UAS pilots, according to 2024 documentation the Air Force provided. In addition, an Air Force written status update states that it is difficult to measure cadet interest in the UAS career field, but the career has been staffed at over 100 percent since 2022. The Air Force provided documentation to support these staffing levels. Finally, while the Air Force does not provide any evidence regarding UAS pilot workload or discuss that issue in its... response, it provided evidence that UAS pilots accept Air Force retention bonuses at a higher rate than manned pilots, which the Air Force uses as an indicator of quality of life. In short, these actions meet the intent of our recommendation and enable us to close it as implemented.

| Department of Defense | To help the Air Force in its effort to address UAS pilot shortfalls, and to help the Air Force ensure that its strategies are having the intended effects, the Secretary of Defense should direct the Secretary of the Air Force to monitor the extent to which that achieving the human capital goals in its strategy helps the Air Force achieve its programmatic goals. | DOD partially concurred with this recommendation. According to headquarters Air Force officials, the Air Force has three program goals that are related to addressing UAS pilot shortfalls: to (1) meet combat demand, (2) staff enough personnel to UAS units to allow UAS pilots time to train and take part in development activities, and (3) provide surge UAS combat capabilities when needed. As of September 2019, the Air Force does not have enough personnel in UAS units to allow UAS pilots time to train and take part in developmental activities-known as being in "dwell." As of November 2019, Air Force officials stated that they are able to "meet combat demand" but are not able to provide...

| Department of Defense | To help the Air Force in its effort to address UAS pilot shortfalls, and to help the Air Force ensure that it is poised to meet future needs for UAS pilots, the Secretary of Defense should direct the Secretary of the Air Force to explore the potential use of additional flexibilities that would enable it to increase the number of UAS pilots in its workforce. | DOD partially concurred with this recommendation. In a March 2018 report to Congress, the Air Force stated it had developed a deliberate plan to integrate enlisted pilots in the RQ-4 Global Hawk UAS as it provided the ideal environment to expand mission flexibility. Further, as another way to build capability in support of human capital strategies by using flexibilities, an Air Force selection board met in July 2017 to consider total force officer as well as civilian candidates for various test pilot positions to include test UAS pilots. The Air Force also sought legislative changes to allow the Air Reserve Component to perform full time, 24/7, 365 operational missions such as the UAS...

| Department of Defense | To help the Army in its effort to address UAS unit training shortfalls, and to help the Army identify challenges that UAS pilots face in completing their training, the Secretary of Defense should direct the Secretary of the Army to collect feedback from UAS pilots in UAS units, such as by surveying, or conducting focus groups with them. | DOD partially concurred with this recommendation. In its initial comments, DOD stated that incorporating feedback from the field is already an element of the Army's strategy for improving the sustainability, maturity, and health of its UAS workforce. DOD stated that our findings will reinforce the importance of using feedback to improve and refine the Army's overall strategy. In September 2019, Army Headquarters officials reiterated previous statements that they made that the Army has multiple agencies and systems that gather feedback to refine and improve UAS programs. However, the Army has not collected feedback from UAS pilots in UAS units via surveys, focus groups, to help the Army...

| Department of Defense | To help the Army in its effort to address UAS unit training shortfalls, and to help ensure that Army Shadow units meet minimum training requirements, the Secretary of Defense should direct the Secretary of the Army to revise its strategy to address UAS training shortfalls to ensure that it is fully tailored to address training issues and address factors such as lack of adequate facilities, lack of access to airspace, and the inability to fly more than one UAS at a time. | DOD partially concurred with our recommendation that the Army revise its strategy to address UAS training shortfalls to ensure that it is fully tailored to address training issues and address factors such as lack of adequate facilities, lack of access to airspace, and the inability to fly more than one UAS at a time. DOD stated that the Army has already taken steps to continuously improve its training strategy and that our findings will underline the importance of those initiatives, but that additional direction related to our recommendation is not necessary. In their July 2018 written update, Army officials responded to this recommendation by discussing a regulation regarding readiness...

| Department of Defense | To help the Army in its effort to address UAS unit training shortfalls, and to help the Army ensure that it is basing its decisions to select individuals for UAS pilot training on sound evidence and to help it take advantage of the key benefits associated with effective personnel selection that could include reducing training costs, improving job performance, improving retention of qualified personnel, enabling leadership development, and enhancing organizational effectiveness, the Secretary of Defense should direct the Secretary of the Army to validate that the Armed Services Vocational Aptitude Battery is an effective predictor of UAS pilot candidate performance in UAS pilot training and job performance. | DOD partially concurred with our recommendation that the Army validate that the Armed Services Vocational Aptitude Battery is an effective predictor of UAS pilot candidate performance in UAS pilot training and job performance. DOD stated that it believes that the current graduation rate of soldiers from its UAS pilot school of 98 percent is an indication that the existing personnel resource predictors and practices are sufficient. It also stated that periodic re-validation is prudent, but specific direction to do so is not necessary. In its July 2018 written update about this recommendation, Army officials stated that the successful graduation rate from UAS Advanced Individual Training...

| Department of Defense | To help address personnel shortages and meet mission needs cost effectively, the Office of the Secretary of Defense, through the Under Secretary of Defense (Personnel & Readiness) should direct the Air Force and the Army to evaluate the workforce mix and the use of federal civilians for UAS pilot positions. | DOD concurred with this recommendation. In December 2017, the Assistant Secretary of Defense (Manpower and Reserve Affairs) issued a memo to the Air Force and the Army requesting implementation of actions to meet the recommendations from this GAO report on UAS Human Capital Planning. As part of that memo, the Air Force and the Army were requested to provide an assessment of current UAS workforce mix and plans and of potential modifications to that mix to be included in their program plans for fiscal year 2020. More specifically, they were instructed to include an assessment of the current military manpower allocations for UAS operations, evaluating military essentiality and identifying...
