Thank you. I'm going to come back to you if I have time.
My next question is for Professor Huebert.
You talked about a different way of looking at our procurement, where it's, forgive the pun, a pipeline of procurement. You're creating this constant conveyor belt of ships, any kind of asset in terms of our military defence. It's different, as you said, from what we've done in the past, where we make the big order, the big announcement, the big splash; we hope for the assets to be delivered, and then don't touch them for the next couple of years.
Since as part of the defence policy review we're looking at such questions, what would you recommend to us? Would you recommend that we move to a long-term strategy that has short-term objectives to fill the current gaps we have in capability in naval—of course, right now we're looking at naval—but aerial and land as well? Then, for a long-term strategy, it will require a different way of thinking in government, because every time a new government comes in there is review of projects and so on. How would that long-term planning and long-term strategy look for our military procurement?
