HH - I'm not sure what the contractural arrangements were but hosting Spanish, Italian and USMC Sqaudrons on the CVS was always an option, particularly when Herrick diverted the Harrier Forces attention (rightly) on supporting the effort. It allowed the ship's company to retain it's experience with fast jet flight ops and gave allies an alternative option when their own decks were unavailable.
If the Indian SHARs were ever an option I'm sure many people would be delighted to see it happen, however I understand that they're being replaced with Mig-29s for the Indian Navy, so not really an option (stopping being the issue rather than taking off).
