On the first question, as I indicated, the $470 million we've approved for the additional Australian aircraft includes the upgrades, certain interoperability and other aspects that would be included. In the overall $3 billion, and that's where we go from the $1.2 million to the $3 million, it includes bringing in 94 aircraft on an incremental cost perspective all the way to 2032. It's not all of them in 2032, but we have a glide path from 2026 on. That focuses on the interoperability upgrades, the additional maintenance, the spares—all of those aspects.
We've learned over time, as we did “Strong, Secure, Engaged” and as we've seen repeatedly in the budgeting for major capital projects and things of that nature, that early costs lack fidelity. We're not sure what they're doing. They could be made public. People ask about them, and then we find ourselves entrenched in this position where we've come up with a number with really incomplete information.
As with all departments, we now have a chief financial officer model. He is accountable for those numbers. He attests to those numbers. There are certain things we're doing in the incremental upgrades that we cost as they get ready to be approved and go forward, but in the broadest sense, without fully understanding what will be the path forward, whether it will include radars, what it will be, those things have not been costed.
