I'm really not the right person, in the context of capability and future capabilities. That would be our vice chief, chief of force development, and others.
What I will say from experience, having a couple of times been involved in looking at nuclear submarines in Canada, is that it's a very complex, massive undertaking. I was involved with this a few decades ago and went to sea in British, French, and American nuclear submarines. It's a very expensive and very massive undertaking.
As a country, of course, we have a nuclear industry that actually puts us ahead of others who may look at this, but it is a massive undertaking. At this point I'm not aware of any discussions in that vein, but to be fair, it's really a question best addressed to our vice-chief and the commander of the navy.
