Thank you very much for the questions.
On the first one, it is 18 flyable aircraft. We have said up to seven additional ones, for spares. We will likely not go that far. The Royal Australian Air Force has been very forthcoming. In fact, they've provided us with a broad number of aircraft to look at, as well as a large number of spares.
Rather than bring aircraft to Canada and then disassemble them, we have actually gotten enough major assemblies for them that it will likely only be a couple of additional aircraft. That's what we'll look at. Again, the additional ones would be as required for spare parts, without just burdening ourselves with it.
The $470 million actually includes a number of things, as you indicate. It's the aircraft themselves and their upgrades. We want to do what we would call a repair and overhaul of all the engines. We're going to go through our checkpoint tree for structure. We want to make sure we're covering all of that, to make sure that it happens. The first aircraft will come in the late winter to spring. They will have flyable hours on them already. As you've indicated, some of the immediacy is for configuration management and training, the NVIS lighting and the ejection seat.
There are other aspects of the $470 million. With some things, we're resituating ourselves for future fighters. For example, we're looking at moving the test establishment from Cold Lake to actually having a federal government centre of excellence here in Ottawa. That's included in it.
We're contemplating a number of the upgrades—and we've talked about it—around interoperability and some of the other things. We've included those costs in it, so that we can be very forthcoming and indicate the initial maintenance checks, tests, evaluation and upgrades that we will do, as well as some of the upgrades we envisage, as a result of introducing these aircraft and growing the fleet.
