The All-domain Anomaly Resolution Office (AARO) is the U.S. Department of Defense office responsible for investigating unidentified anomalous phenomena (UAP) in the air, in space and underwater. It was established on 20 July 2022 under the Office of the Secretary of Defense, with its director reporting to the Deputy Secretary of Defense, and its role is set out in law at 50 U.S.C. § 3373.[1][2]

AARO is the latest in a line of modern U.S. efforts. The Defense Intelligence Agency's AAWSAP/AATIP program ran from 2007 until funding ended in 2012. On 4 August 2020, Deputy Defense Secretary David Norquist approved the Unidentified Aerial Phenomena Task Force (UAPTF) within the Office of Naval Intelligence, which issued a preliminary assessment in June 2021 that could explain only one of 144 military reports. On 23 November 2021 the task force was replaced by the Airborne Object Identification and Management Synchronization Group, which in turn became AARO.[1][3][4]

Physicist Sean Kirkpatrick was AARO's first director, serving until 1 December 2023. His deputy, Timothy Phillips, on assignment from the Office of the Director of National Intelligence, served as acting director. Jon Kosloski was named director on 26 August 2024.[1][5]

Reporting and reports

AARO launched a public website in late August 2023, after delays; at first it lacked a way for the public to submit reports, which earlier laws had required. It also provides a secure channel for current and former government employees to report information about alleged programs.[1]

The January 2023 annual report, produced with the ODNI, covered 366 new reports. About half had ordinary explanations such as small drones, balloons and radar clutter, while 171 remained uncharacterised; some of these were said to show unusual flight characteristics. Officials said there was no evidence of extraterrestrial origin.[1][6] In December 2022 Under Secretary of Defense Ronald Moultrie said the department had seen nothing indicating alien origin.[1] In November 2024, presenting the fiscal year 2024 report, Kosloski said AARO was still analysing a small number of "true anomalies" that it could not explain.[1][7]

Historical Record Report

In March 2024 AARO published the first volume of its Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena, covering U.S. investigations from 1945 onward, including Projects Sign, Grudge, Twinkle and Blue Book, AAWSAP, AATIP and the UAPTF. It found no empirical evidence of extraterrestrial technology and no evidence of unacknowledged programs hidden from Congress. It attributed many claims to misidentified real secret programs and to "circular reporting" among a small group of people.[1][8][9]

The report also disclosed "Kona Blue", a proposal by advocates within the government for a Department of Homeland Security special access program to reverse-engineer any extraterrestrial craft in U.S. possession. DHS leaders rejected it as lacking merit.[1][9]

Criticism

Supporters of disclosure, including whistleblower David Grusch and several members of Congress, have accused AARO of lacking access to all relevant programs and of producing an incomplete historical review. Kirkpatrick said Grusch refused to meet his office, and after leaving he wrote that the claims of hidden programs had not been substantiated.[1][10]
