Thank you.
My second question has to do with cost also.
Icebreaking capability is pretty important. Professor Pharand, the emeritus professor of law at the University of Ottawa, was with us. He has recently written a paper that also talks about the need for an icebreaking capability of the Terry Fox class. He points out that the Russians currently have 12 icebreakers operating, whereas we only have a couple, and that they intend to add more. Your notion of a three-for-one idea sounds very attractive if you think we could have Terry Fox class icebreakers for the cost of the Diefenbaker. Is this something that you know other people have talked about? Has that costing actually been done, to your knowledge?
