In the memo, written on Jul. 22, Gilmore said Marines were struggling “to keep more than two or three of the six embarked jets in a flyable status on any given day.”
Maintainers were able to get spare parts quickly from shore and Lockheed Martin was quick to provide assistance. However, the service will be challenged when the jet deploys on an operational mission under more trying conditions, he wrote.
