Thank you for the question, sir.
Again, it depends on which vessel we are talking about and the level of complexity involved. If you look at the Arctic offshore patrol ships for the navy, the joint support ship for the navy, the auxiliary vessels, in those cases the hull form, the propulsion, and the power generation become the key components in where the complexity brings efficiency and speed.
In the case of those projects, although it will all be managed by us in Public Works, the relationships are a little more straightforward around the shipyards largely performing the role of the prime contractor. Some of the details of how all of the other players are involved have yet to be established in the detailed acquisition contracts. In most cases, given the relative cost, they will go through a form of acquisition themselves, clearly with oversight by Public Works and others.
When we get into the next generation of surface combatants for the navy, which are much more complex, in that case what we would call the combat systems, the sensors, and the weapons are the majority of the costs and the majority of the complexity. We usually describe it as a combat system that's wrapped in a hull.
We've just started the consultation on that project. Again, Public Works is leading that. We kicked off the industry day in the middle of November, and have gone out to industry. There are many models used internationally. We've gone out, we have some views on it or some options, but again, in learning from the shipbuilding strategy of the importance of early consultation, we've gone out to industry and asked how we should form the relationships between the shipbuilder and combat systems integrator and what we can do. In that case we're very early in the process, and I've just opened that up.
