The UAP Task Force (UAPTF) was a Department of Defense initiative established in August 2020 to detect, identify, and attribute unidentified aerial phenomena encountered by U.S. military personnel. The first formal, officially acknowledged government body dedicated exclusively to UAP investigation, the Task Force operated under the Office of the Under Secretary of Defense for Intelligence and Security and was led by the U.S. Navy. Its most significant public output — a nine-page unclassified report released in June 2021 — acknowledged 144 UAP cases gathered over eighteen months and candidly admitted that the government lacked explanations for the vast majority of them. The UAPTF was superseded by the All-domain Anomaly Resolution Office (AARO) in July 2022.
Establishment & Congressional Mandate
The UAPTF was formally established on August 4, 2020, by Deputy Secretary of Defense David Norquist. Its creation was driven in large part by congressional pressure that had been building since the December 2017 New York Times disclosure of the AATIP program, combined with intensifying reporting of UAP incidents by Navy aviators. In December 2020, the Consolidated Appropriations Act directed the Department of Defense and the Office of the Director of National Intelligence (ODNI) to jointly produce an unclassified report on UAP within 180 days — a mandate that ultimately produced the landmark June 2021 Preliminary Assessment.
The Task Force’s mandate was threefold: to detect, identify, and attribute UAP observed by U.S. military forces; to assess any threat they posed to national security; and to share relevant findings with military services and combatant commands. Its Navy-led structure reflected the fact that the preponderance of documented UAP encounters had come from naval aviation — particularly the USS Nimitz incidents of 2004 and the USS Theodore Roosevelt encounters of 2014–2015.
First Director: Jay Stratton
The UAPTF’s first director was Jay Stratton, a senior defense intelligence executive with over three decades of combined military and civilian government service. Stratton had previously played key roles in both the Advanced Aerospace Weapon System Application Program (AAWSAP) and the Advanced Aerospace Threat Identification Program (AATIP) — making him arguably the most experienced UAP program manager in U.S. government history. Under his direction, the UAPTF compiled and analyzed the case data that formed the basis for the June 2021 report, and developed the analytical framework that classified UAP into five potential explanatory categories. Stratton left government service in 2022 and has since made public statements about having directly observed what he described as non-human craft and non-human beings.
The June 2021 Preliminary Assessment
On June 25, 2021, the Office of the Director of National Intelligence released the “Preliminary Assessment: Unidentified Aerial Phenomena” — the UAPTF’s primary public output and the first official, unclassified U.S. government report on UAP in the modern era. The nine-page document examined 144 UAP reports from U.S. government sources, covering incidents between November 2004 and March 2021. Of these, analysts could explain only one (identified as a large, deflating balloon). The remaining 143 cases were unresolved.
The report grouped potential UAP explanations into five categories: airborne clutter (birds, balloons, drones); natural atmospheric phenomena; U.S. government or industry developmental programs; foreign adversary systems; and a catch-all “other” category for objects that exhibited unusual flight characteristics or performance signatures beyond known technology. The report explicitly noted that UAP “probably lack a single explanation” and flagged eleven incidents involving “unusual UAP movement patterns or flight characteristics” that required further analysis. It also raised concerns about flight safety and national security and called for improved data collection, standardized reporting, and reduced stigma around UAP reporting within military channels.
The Assessment was deliberately constrained in scope and cautious in language — it made no claims about extraterrestrial origin and declined to speculate about the nature of the unexplained phenomena. Critics, including some of the military whistleblowers who later testified before Congress, argued that the unclassified report represented only a fraction of what government analysts actually knew, and that the most significant UAP data remained withheld in classified annexes.
Transition to AARO
The UAPTF was succeeded by the All-domain Anomaly Resolution Office (AARO), established within the Office of the Secretary of Defense in July 2022 under the FY2022 National Defense Authorization Act. AARO represented a significant expansion in both mandate and institutional scope: unlike the Navy-led UAPTF, AARO was designed to coordinate across all military services, the Intelligence Community, and other relevant agencies, and to investigate UAP in all domains — air, sea, space, and subsurface. The transition reflected congressional dissatisfaction with the pace and transparency of UAP investigation under the UAPTF structure.

The UAPTF’s work intersected with the government careers and public testimonies of several figures now central to the UAP disclosure landscape. Jay Stratton served as its founding director. David Grusch, who later became the most prominent UAP whistleblower of the 2020s, worked as the National Reconnaissance Office’s representative to the UAPTF and later served as its co-lead for UAP analysis. The Task Force’s data collection drew on incidents reported by pilots including Ryan Graves and, through the historical record, Commander David Fravor.
