The Pentagon's official office for investigating unidentified anomalous phenomena across all domains
The All-Domain Anomaly Resolution Office (AARO) was established by the U.S. Department of Defense in July 2022 to replace the UAP Task Force (UAPTF). It represents the most comprehensive U.S. government effort to date to investigate unidentified anomalous phenomena (UAPs) across all domains - air, sea, space, and transmedium.
AARO operates under the Office of the Under Secretary of Defense for Intelligence and Security and is tasked with synchronizing efforts across the Department of Defense and other federal agencies to detect, identify, and attribute objects of interest in all domains.
AARO's mission is to minimize technical and intelligence surprise by characterizing, understanding, and resolving unidentified anomalous phenomena. This includes assessing potential threats to national security and flight safety.
AARO evolved from previous UAP investigation programs including the UAP Task Force (2020-2022) and the Advanced Aerospace Threat Identification Program (2007-2012). It represents a significant expansion in scope and authority.
