Yes I've been to the Bay of Bengal. And yes it is as humid as a Turkish bath (as are many other places on earth) so what price your precious Fleet air defence in such circumstances - let alone projecting power ashore (the RN's re-invented raison d'etre - and a role I completely subscribe to).
I'm sure you didn't mean to compare the SHAR with the Mig 15 or the F86 - or then again ........
