Certainly there have been differing changes in its requirements. It started, basically, at the cusp of Afghanistan. There was a requirement then. Then we needed an urgent operational request, so we brought in two temporary systems to operate there. Since then, there have been differing scopes of what we want to use the project for. I mean, there are multiple different factors.
In some ways, it's a good case study to show a lot of the issues that we see in delays in defence procurement, to show that we see differing changes in requirements, differing interests in actually spending for it and in what we want to use it for. It is actually, in some ways, a microcosm with a lot of these issues brought together in one program.
