I will start by saying that it's important to keep in mind that the American program is still just at the theoretical or intent stage, and it hasn't actually delivered anything yet.
With respect to the American Navy, its track record on delivering large surface ships on time and on budget isn't great, unless they've already made three or four or five dozen of them first, which is the case with the Arleigh Burke class destroyers.
That's also an important consideration, if you think about that Constellation class as a potential alternative for Canada and that Canada does not have a plan to keep buying Flight III Arleigh Burkes like the United States does. We don't have aircraft carriers. In making analogies to other programs elsewhere, it's important to try to understand the differences between what we're looking to do with our one program of acquisition versus what other countries are doing in acquiring multiples of them.
There are actually a fair number of similarities, though, in terms of the basic approach that the Americans have taken and what we're doing. Some of those Congressional Research Service reports, as an example, point to them being inspired by the DNA of that ship, but they are extensively modifying it. As Mr. Williams pointed out, they are changing it along three dimensions, and they're also basically changing out all of the combat systems that go into it, which is where the real key risk and the real integration challenges come on a project like this. Canada is doing a version of the same thing.
