In your overall readiness, how flexible is the fleet overall? We talked about submarines briefly and the capability of diesel submarines versus nuclear submarines. We've had previous testimony that diesel submarines, in particular in training with our allies that have nukes, are hugely important in that exercise because it allows the merging of both capabilities. Of course, the quietness of our submarines and the stealth capabilities, quite frankly, underwater are important, but so are some of the elements that you deal with in terms of the whole-of-government approach when you're working with DOM ops and when you're working with, of course, other elements in land and air capabilities.
I only have probably a minute to go. Can you just briefly describe the overall flexibility of the fleet and being able to deal with all of those elements at once?
