With respect to the supply ships, as I think I indicated earlier, in the normal process of decommissioning one ship to commission a new ship, we would naturally tend to decommission something like a year or a year and a half prior and then conduct the training to be able to take on the new ship upon commissioning. That's a ship-per-ship issue. What we would certainly try to do is, having come up with a plan to transition into the lead ship of the JSS, keep one of the older supply ships running so that we would always have an operational capability, if we could.
Actually, until we move to the next stage of the joint support ship process and actually award a contract and have some confidence in the delivery time, we won't finalize our plans for that transition work between the old and the new.
With respect to the Iroquois-class replacement, the navy at this point is working to define the requirements for a new class of ship. So that's internal work that's going to go on for some time, yet before we're prepared to go to industry.
With respect to the issue of submarines, I've certainly heard nothing at all that would indicate that. We're pressing full ahead to deliver operational capability with the boats.
