That's what I was trying to get across barnstormer.
The Tornado, Jaguar, Harrier etc etc etc spent most of their life training for war, and only in the last decades that they were called on to do it in anger, the Vulcan only managed it at the end of it's life, would you have not spent the money to develop that, as it only went to war once and for a limited time, and the Valiant and Phantom I think never did.
