AARO

AARO (All-domain Anomaly Resolution Office) is an office of the U.S. Department of Defense established in 2022 that investigates and analyzes reports of UAP phenomena (unidentified aerial, maritime and space objects).

AARO (All-domain Anomaly Resolution Office) is an organizational unit of the United States Department of Defense, established in 2022 as the successor to the earlier UAP working groups (UAPTF, then AOIMSG). Its task is to collect and investigate reports of unidentified aerial, maritime, space and transmedium phenomena (UAP) and to report the results to Congress.

What AARO claims

In its report on the historical investigation of UAP phenomena, released in 2024, AARO concluded that it found no evidence of extraterrestrial technology or of a secret crashed-spacecraft retrieval program. According to the office, most reports can be explained by conventional means (drones, balloons, atmospheric phenomena, optical illusions), but some of them remained unresolved due to a lack of data.

Criticism and dissenting views

Some retired government employees and officials, including David Grusch, have disputed AARO's findings, claiming that the office does not have access to all relevant, deeply classified programs and that the government actually possesses materials related to objects of unknown origin. AARO's leadership has so far not substantiated these claims with concrete evidence.

AARO was originally headed by Sean Kirkpatrick, who was then succeeded in the office's leadership post by Jon Kosloski.
