The unclassified summary of Evaluation of the DoD’s Actions Regarding Unidentified Anomalous Phenomena (DODIG-2023-109) is a publicly released document produced by the U.S. Department of Defense Office of Inspector General. The underlying evaluation was conducted between May 2021 and June 2023 in accordance with quality standards published by the Council of the Inspectors General on Integrity and Efficiency (CIGIE),35 with the objective of determining the extent to which the United States Department of Defense (DoD), its military services, defence agencies, and Military Department Counterintelligence Organizations had taken intelligence, counterintelligence, and force protection actions to detect, report, collect, analyse, and identify Unidentified Anomalous Phenomena (UAP). The James M. Inhofe National Defense Authorization Act for Fiscal Year 2023 defined UAP as encompassing airborne objects, transmedium objects or devices, and submerged objects or devices that are not immediately identifiable.12

The document provides a historical overview of DoD UAP activity, noting that efforts to identify and understand the origin, capabilities, and intent of UAP have been infrequent and inconclusive over past decades,1 with military pilots accounting for many of the reported sightings.2 The United States Air Force and United States Navy have historically led the development of UAP reporting policies and procedures.3 The DoD’s first formal UAP-focused effort dates to 1947-12, when the Air Force Chief of Staff established Project Sign to investigate unidentified flying object observations;4 Air Force personnel investigated 243 reported UAP sightings under that programme between 1947 and 1949.5 In 1952, the Air Force Director of Intelligence initiated Project Blue Book,6 under which personnel investigated over 12,000 reported sightings between 1952 and 1969.7 After a long gap, select members of United States Congress initiated and funded the Advanced Aerospace Weapon Systems Applications Program (AAWSAP) around mid-2000 under the direction of the Defense Intelligence Agency (DIA);8 however, since that point the DoD attempted several programmes for coordinating DoD-wide UAP reporting, none of which were ever fully implemented.9

Congressional pressure intensified in subsequent years. The Senate Select Committee on Intelligence identified concerns in its report on the Fiscal Year 2021 Intelligence Authorization Act that the U.S. Government lacked a unified, comprehensive process for collecting and analysing UAP intelligence,15 and congressional committees included UAP-related language in the National Defense Authorization Acts for Fiscal Years 2019 through 2023.14 In response to growing concerns about flight crew safety, national security, and adversary technology, Congress directed the DoD through the Fiscal Year 2022 National Defense Authorization Act to establish a central office for UAP matters.10 A series of institutional structures were created and dissolved in rapid succession: the Unidentified Aerial Phenomena Task Force (UAPTF) was established in 2020-08 to develop standardised reporting requirements,16 and in 2021-06 the UAPTF and the Office of the Director of National Intelligence (ODNI) issued the congressionally mandated Preliminary Assessment on UAP, which found UAP reporting data to be largely inconclusive and government-wide consolidation of reports to be inconsistent.18 In 2021-11, the Deputy Secretary of Defense directed the Office of the Under Secretary of Defense for Intelligence and Security (OUSD[I&S]) to establish the Airborne Object Identification and Management Synchronization Group (AOIMSG) as the successor to the UAPTF;19 the AOIMSG never reached operational capability and was disestablished on 2022-07-15.20 The All-domain Anomaly Resolution Office (AARO) was subsequently established in July 2022 to take on the duties previously assigned to the AOIMSG.21

The OIG’s findings were critical of the DoD’s overall approach. The OIG determined that the DoD had not used a coordinated approach to detect, report, collect, analyse, and identify UAP,22 that geographic combatant commands had been largely excluded from the development of UAP policies and procedures,23 and that different DoD components had developed varying processes for handling UAP incidents.24 Crucially, the OIG found that the DoD had not issued a comprehensive UAP response plan identifying roles, responsibilities, requirements, and coordination procedures.25 At the service level, the United States Air Force designated UAP as a Special Interest Item, requiring aircrews to document and report observations within 24 hours of engine shutdown using the Marauder Mission Reporting System;26 the United States Army relied on the same Air Force system, having developed no UAP-specific processes of its own.27 The Military Department Counterintelligence Organizations – Army Counterintelligence, the Naval Criminal Investigative Service (NCIS), and the Air Force Office of Special Investigations (OSI) – had sent some UAP incident reports to AARO, but the DoD did not formally require them to do so. The OIG concluded that, as a result of the absence of overarching UAP policy, the DoD lacked assurance that national security and flight safety threats from UAP had been identified and mitigated.28

DODIG-2023-109 issued five recommendations. Recommendation 1 called on the Under Secretary of Defense for Intelligence and Security, in coordination with the AARO Director, to issue a DoD-wide policy integrating UAP roles, responsibilities, requirements, and coordination procedures into existing intelligence, counterintelligence, and force protection frameworks;29 the Under Secretary agreed, noting that the findings largely predated AARO’s establishment and that AARO had since developed an analytic framework, science plan, operational framework, and strategic communications plan.30 That recommendation was left resolved but open.31 Recommendations 2, 3, and 4 directed the Secretaries of the United States Army, United States Navy, and Air Force respectively to issue interim service-level UAP guidance pending DoD-wide policy. The Secretary of the Navy did not provide official comments as requested,32 and the Secretary of the Air Force similarly did not provide official comments.33 Recommendation 5 directed the Chairman of the Joint Chiefs of Staff to issue guidance to geographic combatant commanders on UAP detection, reporting, collection, analysis, and identification; the Joint Staff issued the requested guidance,34 and that recommendation was resolved and closed.
