Let me give you an example of the Cyclone, which is the Sea King replacement. The reason we have reprofiled money there is because the contractor hasn't delivered. I wanted it quicker, but they didn't deliver, so we reprofiled.
The challenge with reprofiling is defence inflation is such that a dollar today is worth much less than an annual inflation rate moving forward. Ideally, we'd love to be spending it now, but sometimes we can't, and that's not something we control either.
