Yes. I would say that we're still working on the numbers, for sure, of what the cost will be on all of these projects.
It's important to note, and I know the committee is aware of this, that we're building an industry in this country—a shipbuilding industry. The numbers we used to estimate in the past were based on the sort of run rate of established shipyards.
Obviously your cost structure is going to be different when you're regularly building a class of ship. You're going to have an efficiency rate, which we are now seeing, for example, at Irving on the AOPS. Each ship is costing less than the one before, because they are achieving that efficiency.
