Thank you for that question.
To go back to what I said on Tuesday, when we look at the needs of the future we have to look at both domestic and international environments where technology will cause us some significant challenges.
It's important to remember that one of the things we're doing is buying a single fleet of fighters. To have, let's say, a home fleet and an away fleet is very expensive. We went away from that in the 1980s, with the F-18, and to go back that way would be even more expensive. So no matter what we consider as the future option, we have to look at a single fleet, multi-roled aircraft to meet all of Canada's needs.
