The Navy’s decision may be part of a larger trend. In May 2017, the foreign-policy magazine National Interest obtained emails from top Navy officials discouraging the disclosure of readiness numbers—figures that report how many aircraft are ready to fight in the event of a major conflict. At the time, nearly two-thirds of the Navy and Marine F-18s were unfit to fly. In 2015, the Marines’ CH-53E fleet was in even worse shape, with just 23 percent of aircraft able to fly a mission. A March 2017 email from the Pentagon spokesman Captain Jeff Davis instructed the heads of public affairs across the military to “be cautious about publicly telegraphing readiness shortfalls.” The guidance reportedly came from Secretary Mattis himself, according to National Interest.
