AARO (All-domain Anomaly Resolution Office)

2022-present

The All-domain Anomaly Resolution Office (AARO) is the U.S. Department of Defense office responsible for the synchronized detection, identification, and resolution of unidentified anomalous phenomena.

What does AARO do?

Established in July 2022, AARO consolidated and expanded earlier UAP efforts. It reports within the Office of the Under Secretary of Defense for Intelligence & Security and coordinates with the intelligence community to investigate UAP across all domains, air, space, sea, and transmedium, and to address potential threats to U.S. operations and national security.

How is AARO different from the UAP Task Force?

AARO is the successor to the UAP Task Force (UAPTF), with a broader, all-domain mandate and a permanent statutory footing established through defense authorization legislation.

What has AARO concluded so far?

AARO has reviewed hundreds of cases and, in its Historical Record Report, stated it found no verifiable evidence of extraterrestrial technology or of concealed reverse-engineering programs, conclusions contested by some whistleblowers.
