So still two locations and two sets of manning (RNAS Yeovilton still had manpower that was not part of the carrier). Granted there were other assets at Yeovilton
Appropo of nothing really but just for the record. At around the time of the quoted period above about 135 aircraft were operating from Yeovilton. The manpower retained purely to support the Harrier comprised a few in the Sim (needed for 899) and the LOX bay (needed for 899). Pretty well all other manpower was for common services. I am not sure the same could be said for COTT etc where the station existed purely for a single aircraft type.
Kevlar on!
