FV,
The FAA don't necessarily need the STOVL, and there are many debates about that. That's driven the Carrier design and it's a hot topic. The RAF, however, need the Eurofighter to keep all those pilots in that they have been promising the job to, for the last 5 years! Whether they need the A2G role is again a difficult point, and it all revolves around the cost doesn't it? Like everything.
