I'll start, and then I'll ask Commander Greenwood to add slightly more.
Absolutely, we need a domestic shipbuilding industry for construction and ongoing maintenance of our vessels, and I think the same applies to the other government fleets. So the degree to which we can provide predictability certainly helps the shipbuilding industry.
If I use the example of a joint support ship, the openness and transparency that has characterized the project has allowed the industry to stay ahead of our requirement and to make sure they have the capacity ready when the time comes to take on the job.
Certainly one of the things that is offered by a steady shipbuilding program is that predictability that allows industry to make efficient investments and allows us to maintain a steady output of government fleets as well, rather than having the dips in output that are typical when one is engaged in batch—that is, very short-term—upgrading or construction.
