The Air Force is not preparing to put its B-52 nuclear bombers on 24-hour alert, the service said Monday, adding that a misunderstanding might have led to a report claiming those preparations are underway.

Updates to facilities, exercises, and training related to the B-52 Stratofortress aircraft at Barksdale Air Force Base in Louisiana are done routinely to ensure the service is prepared, said Ann Stefanek, the chief of Air Force media operations at the Pentagon.
