I don't believe so, Mr. Chair.
In fact, we rely on three systems. For our F‑18s, we use a strategic tanker system, a command and control system, and the fighter aircraft themselves. It is essential that we plan for this capability in the Far North.
Regardless of aircraft, to be able to interdict any incursions in Canadian or North American aerospace requires the close co-operation of strategic tankers, fighter aircraft and command and control systems. It's not just looking at the capacity of any given fighter that has been selected; it's how those three systems interplay.
Today, as an example, when an F-18 is dispatched, they launch, refuel, and they move to the area where they're going to intercept. They intercept, refuel, and they come back. This is a tried and tested system that is utilized by NORAD.
