We do buy off the shelf. There are recent examples of the capabilities that we were seeking existing in military form that we could buy directly; C-17s and the C-130Js are two examples of equipment that was bought off the line, basically as is.
In other cases, because of our particular environment, the equipment that comes off the line does not meet all our requirements. It requires modification to meet Canadian demands. We own probably the toughest geography in the world, as far as climatic conditions and distance go. We are the second-largest country and we have the most coast. Nobody else has that challenge, and certainly we don't have the resources that other nations do to cover their geography. When we look at what we need, we also have to consider what we expect it to do, both at home as part of that core mission and as it goes abroad. Because we don't have the layers and the density of resources that other big nations do, we have to take that into account, and therefore sometimes we have to modify the equipment so that it can cover more ground in terms of both capabilities and geography.
A good example is the Chinook Foxtrot. It is a fine airplane, but the baseline model has a very short range, and when you apply that in Canada, it would be an extreme limitation for us to be able to operate at home. The Chinook Foxtrot that we are procuring will have double the range, about 1,200 kilometres, which is significant when you're trying to do domestic response in the given times that we're normally expected to respond in. It's a tremendous advantage for us to have that capability at home, and certainly abroad, when we operate internationally in some very demanding environments where sometimes logistical support is not there. We will need that range to be able to do our mission.
