Joint Base Andrews, one of the nation�s most sensitive military bases and home to Air Force One, has been locked down after reports of a man carrying an �assault-style� rifle on Thursday, authorities said.

The Maryland base was locked down after the person was reportedly seen near the base�s housing area, according to the base�s Facebook page.

Staff Sgt. Jared Duhon, a spokesperson for the base, said no shots have been fired. There was no immediate report of any injuries and additional details were not immediately available.

Joint Base Andrews, a few miles outside Washington, is home to the fleet of blue and white presidential aircraft, including Air Force One and the �doomsday� 747 aircraft that can serve as the nation�s airborne nuclear command and control centers if needed.

Last month, an intruder breached the base and gained access to part of the base�s housing complex. A resident opened fire on the trespasser. And in February 2021, a man got through the military checkpoint onto the installation, then through additional fenced secure areas to gain access to the flight line and climb into a C-40, which is the military�s 737-equivalent aircraft used to fly government officials.

�Security Forces foot and mobile patrols are out looking for the suspect,� the Facebook post read.
