JFH proved the ability of RAF Harrier squadrons to maintain deck capabilities through short deployments, while using their land-based time to concentrate on other skill sets. JFH also proved the ability of RAF squadrons to maintain a credible air power capability from the deck of RN carriers
I'm sorry but this is simply not correct. There is a big difference between getting a jet on and off a carrier without crashing set against maintaining a credible air power capability. How many Harrier Sqns had a night CVS capability for example? None.
Unfortunately far too often it would seem the RAF mistake popping on and off a carrier every so often to actually having a credible maritime capability, which takes time and practice. And before the inter-service arguing starts the Naval GR9 Squadron was no different, but at least we recognised it.
