Many thanks as always 'Engines' for your input.
For '500N' the Spanish LHD was designed for operating F-35Bs. Oz LHDs are the same on the exterior as that original design; and mostly I'm told in interior with some minor mods to best suit our purposes. THERMION or whatever the Brits will use on CVFs (if it is not the same) will suffice for surface of the deck treatments. I was learning YankSpeak for our future USMC F-35Bs on Oz LHDs but now I guess the Queens Anglaisich will be necessary also.
sigh.
