Most of the capabilities we're talking about, whether of fighters or ships, are almost half-century decisions. The future fighters that we acquire over the next 10 years will probably fly for 30 years beyond that, if not more. I think it's therefore really important to make sure that we have all the information, that we understand it, that we understand the through life costs, that we understand a number of factors that are extremely complex to get at.
To your earlier question about budgets, it is a question of trying to make sure that we pull all of this information together. I think our minister has explained to us that he's trying to make sure that he moves out, but that he does so in a prudent manner and that he's well informed.
