I would not say there's a specific study, but perhaps I could give a bit of context.
The use of industry to provide support, and how we have traditionally done this, is levels of maintenance. The sailors on board ship do first-level maintenance. I think you had previously asked questions about our fleet maintenance facilities at the second level. Industry has for decades, in the 40 years I've been involved with this, and well before that, always been involved with doing the maintenance.
What is key here is there is often a perception that we're changing the approach by using industry. It is industry that is actually designing, building, and providing this equipment. It is industry that has the detailed knowledge and intellectual property.
We are continuing to use industry as we always have. What's changing a little is around these levels of maintenance. It's not unlike cars, where it used to be that we did some work at home, went to the local garage, and then went to the dealership. Very often people go straight to the dealership. In military equipment there's a bit of a similar trend.
We are trying to use industry, which has to get this heavy maintenance work, bringing them in to try to do some knowledge transfer and work with our fleet maintenance facilities—and it's the same in the air force and the army—to continue to meet that strategic capability.
We haven't looked at it from a security perspective or otherwise because it's always been there. They will always be involved. In fact, they have more knowledge than we do. We're trying to bring them in to make sure that our fleet maintenance facilities continue to be an important strategic asset.
