As we mentioned in our opening remarks, when you had an idea 10, 15, or 20 years ago, by nature you'd go and do a rough order-of-magnitude cost estimate and get an idea of the volume and how many ships you needed, but the truth of the matter is that these things evolve over the course of time.
In terms of the shipbuilding strategy, I think the industry sees that we are spending a lot of time arguing about the number of ships, the cost of the ships, and what number we said 10 years ago. To be quite honest with everyone in this room, that's noise. We need to get on with the business of building the ships that we need for the navy, however many it is based on their operational requirements, and balance it out and move forward on these programs. The technologies are there. The industry is ready and willing to do it. The navy is waiting on their ships.
