NaB,
Problem is, we're not procuring a carrier-borne aircraft any more but a carrier capable one. F35C will spend most of its service life ashore because the carrier will be late and we're only buying one Cat/Trap one. It won't be because we don't want to embark, but that we can't because she's in for servicing. The emphasis has switched and F35C will be looked at to replace lost GR4 strike capability for the RAF.
