First of all, they're going to replace the C-140s, which have been doing extraordinary work for the Canadian Armed Forces and for our allies for the last 45 years, but it really is time to replace those aircraft.
We listened very carefully to the air force. They said what they needed in these aircraft, and it's why we made the decision to go with the P-8A. As you've indicated, the P-8A Poseidon is primarily a submarine hunter, but it's multi-mission in its capabilities. It's operated by all five of our Five Eyes partners and by Norway and Germany. There are real advantages, as the air force can share with you, to interoperability and even exchangeability in these things.
We have an opportunity, because our allies use these aircraft, to train alongside them right now and to accelerate our ability to receive these aircraft and to manage a very orderly but rapid transition from the C-140s to the P-8As, so we need to start investing in that now.
It's investing in the training, but it's also investing in some of the infrastructure that's going to be required in order to support these aircraft when they are delivered. There are some adjustments that need to be made from our existing maintenance facilities, so that work has to proceed. We want to be ready when we want to move quickly.
There's an urgency to this because of the actions of our adversaries. We're seeing a lot more naval, maritime and submarine activity in the North Atlantic, in the Pacific and in the Arctic, and we want to make sure that we have the equipment necessary to deal with it.
