John covered it already, but I would add that as recently as what we've done with Vancouver in New Zealand, you see the importance of your question with respect to naval readiness. Helicopters and ships at sea are vital elements of our delivering it.
I would link that back to Mr. Spengemann's question earlier. At the beginning, he was talking about the outfitting of the navy, naval readiness, and its capacity. Here again, we have a demonstration of the need for multi-purpose capability. Canada operates large helicopters, from the Sea King to the Cyclone, and that allows us to have full combat capability with respect to anti-submarine warfare, as well as in humanitarian operations, where volume and lift are significant components in themselves.
