It was stated that the carriers and the Typhoon were both in the frame. You could certainly argue that land-based aviation is what will be required for the next few years thus carrier aviation could be slowed down. Equally it could be argued, and of course will be, that Typhoon is the future as both Harrier and Tornado will soon be passed their sell-by dates.
NB, I am talking realistic time scales not a couple or years.
