The group will be directed by the under secretary of defense for intelligence and security.

AOIMSG will be the successor to a Navy department called the Unidentified Aerial Phenomena Task Force.

In June the Office of the Director of National Intelligence released a report on more than 140 sightings by Navy pilots and others of unidentified aerial phenomena. “Incursions by any airborne object … pose safety of flight and operations security concerns, and may pose national security challenges,” the Defense Department said in a statement.

The announcement added that AOIMSG is being established “to address the challenges associated with assessing UAP occurring on or near DOD training ranges and installations.”
