There are two phases to the modernization. Block 3 is just finishing and then there's block 4, which is going to put on some defensive countermeasures, and link 16. I know that I'm getting a bit technical.
On husband, the life of most aircraft is predicated on wing life. For instance, we just flew aircraft 307, a C-130, into the museum here in Ottawa, because it had reached the end of its wing life. We know how many hours we have left on those aircraft. We have sufficient to do the tasks that we have in maritime warfare, also in our deployed operations, but we couldn't fly them unendingly on a mission. So it's just more being careful to make sure we manage the capability correctly.
