Mr. Speaker, as I said, this is an important capability. The submarine program has been plagued with difficulties. These are very sophisticated vessels. One person compared their sophistication to the space shuttle in terms of the amount of equipment on board that submarine.
With respect to their availability, we have had use of those submarines at various times since taking possession of them. They are involved in an upgrade right now that will see their availability in the future, and we continue to work toward that process.
