I wonder if Hangarshuffle is talking about the use of a CVS in a LPH role -such as Ark Royal during Telic in early 2003?
Off the top of my head, Hermes carried Junglies as well as Sea Harriers, ASW Sea Kings and later Harrier GR3s during the Falklands War. American carriers have been used as platforms for helicopters and Special Forces on occasion in recent years.
