Fleet Readiness Center East (FRCE) at Marine Corps Air Station in Cherry Point, N.C. is the lead site for depot-level maintenance on the F-35B and has conducted modifications and repair on this F-35 variant since 2013.  

FRCE has expanded its support of next-generation naval aviation by declaring capabilities on a new round of F-35 components including parachutes and the ground maintenance motor pumps. These capabilities build upon the 17 F-35 components the depot previously declared capabilities on in 2020. 

When FRCE declares capability on a component, that means that it has all the required materiel, support equipment, and staffing in order to test and repair components so it may be sent back to the fleet to be installed on F-35s around the world. DVIDS - News - FRCE Declares Capabilities on Next Round of F-35 Components (dvidshub.net)
