The Department of Defense is creating a new investigative body to track and analyze “unidentified aerial phenomena,” as concerns grow about national security risks posed by UFOs.

Deputy Defense Secretary Kathleen Hicks, in a memo released Tuesday, announced the creation of the Airborne Object Identification and Management Synchronization Group, “to assess, and as appropriate, mitigate any associated threats to safety of flight and national security.”

The move comes after the U.S. Director of National Intelligence in June 2021 gave to Congress a report about unidentified aerial phenomena,” or UAPs. The report identified just one of the 144 reported UAP cases as a large, deflating balloon; observers in 18 incidents described “unusual UAP movement patterns or flight characteristics,” which suggested advanced technology.
