I appreciate your continuing to have this line of questioning. As Admiral Newton highlighted earlier, I think there's room for both. We have the knowledge transfer between original equipment manufacturers and our fleet maintenance facilities to allow us to have an in-house strategic and operational capability to do second-line and third-line maintenance of our platforms, and to reliably trust in that.
But I think there's an advantage to trying to find the right balance between industrial provision of service support and in-house support, if for no other reason than managing, as force generators, a force that has to respond to threat to the environment, to changes in circumstances, means that we often have spurious levels that appear in sort of a sine wave, and the flexibility of having multiple service deliveries for our maintenance routine gives us the greatest efficiency going forward.
