Thank you.
Mr. Chair, through you, I just want to finish the question that my colleague Mr. Simms had asked about the Tu-95 incursions into the Canadian air defence identification zone and the sovereignty threat. I think what he's getting at is why, if we can do that with the CF-18, we would need an F-35. Well, the CF-18 is 28 years old today. It's going to be 38 years old by the time we're finished flying it.
The people with other interests in our airspace are not going away, so the simple fact is we still need the capability to meet those aircraft and to exercise sovereignty. Sovereignty is being there to exercise that, regardless of whether it's a Tu-95 that was first built in 1956 but is a completely different airplane today from what it was then.
Can you comment on the continuing need for the type of things that the CF-18 has done but will in a few years be incapable of doing because of age?
