I think that's well said. The PBO has basically used a forecast based on the weight of the ship, and given the fact that we don't really know much about the ship, it's as good of an estimate as you're going to get.
As I mentioned in my opening statement, the former director general for naval construction in National Defence said that you'd need to build three or four ships before you could get an accurate idea of what they're going to cost. It really is a black box.
More transparency is needed, but we also need to be informed on a more continuous basis, and that really is what's missing.
