I just want to ask you about the whole issue of how you define costs. In 2006 we had the JSS project announced for $2.9 billion. I think it was $800 million for maintenance and $2.1 billion for purchase. Now we're hearing that those figures are low-balled, perhaps by tens of billions of dollars, and that we're simply not going to be able to get the ships for that price.
How does that happen? Your department would have a clear sense of what those ships would cost. How is it that we can make an announcement, put a price on it, and then a year and a half later we're being told that we're going to run aground?
