Two of the ones ID’d in the AvPlan will be Reserve, so at least them. As for the active squadrons, that’s still an open question but I believe the intended paradigm for now is one TAI per coast (314 and 251). Maybe one more out of Miramar between 323/232. CVWs IRT F-35C isn’t the equivalent as it was back in the day so it follows that there will be less boat squadrons.
Leave it to the USMC to fly an airplane designed to fly on and off of a boat, with all of the performance comprises associated, but never actually fly it off the boat.
