The All-domain Anomaly Resolution Office (AARO) is an office within the United States Office of the Secretary of Defense that investigates unidentified flying objects (UFOs) and other phenomena in the air, sea, and/or space and/or on land: sometimes referred to as "unidentified aerial phenomena" or "unidentified anomalous phenomena" (UAP). Its director is physicist Sean Kirkpatrick who reports to Deputy Defense Secretary Kathleen Hicks.
AARO was preceded by The Unidentified Aerial Phenomena Task Force (UAPTF), a 2020 to 2021 program within the Office of Naval Intelligence used to "standardize collection and reporting" of sightings of UFOs. UAPTF was detailed in a June 2020 hearing of the United States Senate Select Committee on Intelligence. The UAPTF issued a preliminary report in June 2021. In July 2022, it was announced that the UAPTF would be succeeded as an organization by AARO. NASA's UAP independent study team held a public meeting in June 2023 showing further UAP footage released by AARO.
