Highlights

What GAO Found

The Army and the Air Force face challenges ensuring that the pilots who remotely operate their unmanned aerial systems (UAS) complete their required training. Specifically, a March 2015 Army review showed that most pilots in certain Army units did not complete fundamental training tasks in fiscal year 2014—a finding that GAO corroborated through discussions with pilots in focus groups and unit responses to questionnaires. In addition, Army unit status reports do not require UAS pilot training information, and as a result, the Army does not know the full extent to which pilots have been trained and are therefore ready to be deployed. In addition, Air Force training records from a nongeneralizeable sample of seven UAS units showed that, on average, 35 percent of the pilots in these units completed the training for all of their required missions. Pilots in all of the seven focus groups GAO conducted with Air Force UAS pilots stated that they could not conduct training in units because their units had shortages of UAS pilots.GAO found similar shortages of UAS pilots in April 2014 and in particular, GAO found that the Air Force operated below its crew ratio, which is a metric used to determine the number of pilots needed in units. At that time, GAO made four recommendations including that the Air Force update its update crew ratio. The Air Force concurred with these recommendations and has taken actions, or has actions underway. For example, an Air Force Headquarters official stated that, in February 2015, the Air Force completed the first phase of a three-phase personnel requirements study on the crew ratio and expects to update the crew ratio in 2015. However, at this time, the Air Force has not fully implemented any of the recommendations.

The Army and the Air Force are taking actions to increase the number of UAS instructors, but the Army has not fully addressed the risks associated with using less experienced instructors and the Air Force faces instructor shortages. In order to increase the number of its instructors in response to an increase in the number of UAS units, the Army waived course prerequisites for about 40 percent of the UAS pilots attending the course to become instructor pilots from the beginning of fiscal year 2013 through February 2015.The Army originally established these prerequisites—such as a minimum number of flight hours—for UAS pilots volunteering to become instructors to help ensure that instructors were fully trained and ready to instruct UAS pilots. The Army has taken some steps to mitigate the potential risks of using less proficient UAS instructors. For example, beginning in fiscal year 2015, the Army no longer grants waivers for course prerequisites related to proficiency. However, the Army can continue to grant waivers for additional course prerequisites related to experience. As a result, the Army risks that its UAS pilots may not be receiving the highest caliber of training needed to prepare them to successfully perform UAS missions. Furthermore, as of March 2015, the Air Force had staffed its UAS training squadrons at Holloman Air Force Base at 63 percent of its planned staffing levels. This shortage is a key reason that the Air Force has shortages of UAS pilots across the Air Force, according to an Air Force headquarters official. The Air Force is studying the personnel requirements for its school and expects to report the results of this study by spring 2016.

Why GAO Did This Study

The Department of Defense's (DOD) UAS portfolio has grown over the years to rival traditional manned systems, and, as of July 2013, DOD had acquired over 10,000 UAS, according to a 2013 DOD report. Training DOD UAS pilots, most of whom are in the Army or the Air Force, is an integral part of DOD's strategy to accomplish its mission. Senate Report 113-176 included a provision that GAO review DOD's efforts to train UAS pilots.

This report examines, among other things, the extent to which the Army and the Air Force (1) face challenges ensuring that their UAS pilots complete required training and (2) have taken steps to ensure they have sufficient numbers of UAS instructors. GAO analyzed DOD guidance on training UAS pilots, distributed a questionnaire to Army and Air Force headquarters and units, examined nongeneralizeable training records of seven Air Force UAS units selected because they have the same mission requirements, and interviewed DOD officials. GAO also conducted 18 focus groups with active duty UAS pilots who were selected based on rank and other factors. The results of the questionnaire and focus groups are not generalizable.

Recommendations

GAO recommends, among other things, that the Army require unit status reports to include information on the readiness levels of UAS pilots; and the Army take additional steps to mitigate potential risks posed by its waiver of course prerequisites related to experience for pilots attending the course to become instructors. DOD concurred with each of GAO's recommendations.

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Defense To provide greater visibility over the extent to which Army UAS units have completed required training to leaders responsible for deployment decisions, the Secretary of Defense should direct the Secretary of the Army to require unit status reports to include information on the readiness levels of UAS pilots in UAS units.
Closed – Implemented
DOD concurred with this recommendation. Since May 2016, the Commanding General of Forces Command (FORSCOM) has chaired a Monthly Aviation Readiness Review (MARR) in which review members assess aviation readiness across all aviation organizations including UAS. In August 2018, Army Headquarters officials stated that the Army plans to update Army Regulation 220-1, Army Unit Status Reporting and Force Registration to "bring UAS Operator reporting in line with other Army weapon systems, as UAS readiness was not previously captured." However, as of November 2019, the revision to the Army Regulation had not been published. We requested an update from the Army in September 2020 and again in April 2021 and further updates on Army actions in response to this recommendation are pending the Army's response. In February 2022, the Army provided an update stating that the revision to Army Regulation 220-1 has been approved and is pending publication by the Army Publication Directorate, but that the directorate has a backlog of publications for release. As of August 2022, the Army Publishing Directorate's public website states that the current version of Army Regulation 220-1, which was published in 2010, will remain in effect until September 22, 2022 and that the 2010 version will be superseded by an updated version at that time. In November 2023, an official from the Office of the Assistant Secretary of Defense for Readiness provided documentation from the Army that showed that as of May 2016 Army organizations were directed to participate in a monthly secure video teleconference with the Deputy Commanding General of US Army Force Command to update senior leadership on the readiness of aviation units including UAS units. During the meetings, Forces Command personnel were required to discuss UAS unit flight hour programs. Establishing this requirement meets the intent of GAO's recommendation.
Department of Defense To help ensure that Army UAS pilots receive the highest caliber of training to prepare them to successfully accomplish UAS missions, the Secretary of Defense should direct the Secretary of the Army to take additional steps to mitigate potential risks posed by its waiver of course prerequisites for less experienced UAS pilots attending the course to become instructors, such as by providing additional preparation for current and future instructors who do not meet one or more course prerequisites to enhance their ability to successfully provide training.
Closed – Implemented
DOD concurred with this recommendation. In October 2016, Army Headquarters officials stated that the Army had taken additional steps to mitigate potential risks posed by waiving course prerequisites for less experienced UAS pilots attending the course to become instructors. Specifically, by the end of fiscal year 2016, the Army had put 50 of 106 planned Universal Mission Simulators in place for active duty units and reduced the number of waivers granted for three of four course prerequisites. Army officials also provided documentation to show that it had granted significantly fewer waivers since 2015. For example, in fiscal year 2015, the Army granted 31 percent of the students entering the UAS instructor pilot course a waiver. In fiscal year 2021, the Army granted waivers to about 3 percent of the students, and in fiscal year 2022 to about 4 percent. By reducing the number of waivers the Army grants, it has reduced the risk to the quality of the training for UAS pilots in the Army, thereby meeting the intent of this recommendation. As of July 2022, this recommendation has been closed as implemented.
Department of Defense To increase opportunities to improve the effectiveness and efficiency of UAS pilot training across DOD, the Secretary of Defense should direct the Under Secretary of Defense for Personnel and Readiness to address how the services should coordinate with one another in the strategy on UAS pilot training that the Office of the Under Secretary of Defense for Personnel and Readiness is current drafting.
Open
DOD concurred with this recommendation and stated the Office of the Under Secretary of Defense for Personnel and Readiness was in the process of revising its draft "Department of Defense Training Strategy for Unmanned Aircraft Systems(UAS)" to address inter-service coordination to enable the department to train more efficiently and effectively as a whole. In October 2016, the Director stated that RAND had completed the draft strategy and that the Office of the Assistant Secretary of Defense (Readiness) had begun revising the strategy. An Office of the Assistant Secretary of Defense (Readiness) official working on the revisions stated that the strategy would address our recommendation and coordination among the services. However, as of October 2016, the Office of the Assistant Secretary of Defense (Readiness) had not yet issued the department-wide UAS training strategy. In May 2018, the Director Military Training and Ranges in the Office of the Assistant Secretary of Defense (Readiness)/Force Training engaged a team to review the 2016 draft strategy to recommend a way forward. According to that official, the review was nearing completion and he anticipated presenting their recommendation to the current Deputy Assistant Secretary of Defense for Force Education & Training in late July 2018. In September 2018 this official said that developing a new UAS strategy is not planned and he reiterated again in August 2019 that a UAS training strategy has not been issued. In July 2022, officials from the Office of Personnel and Readiness and the services told us that the department had taken no new actions to implement this recommendation. We continue to believe this recommendation should be implemented. In November 2023, DOD officials told us that they would provide documentation later in the month indicating that DOD had taken action consistent with our recommendation.
