There are a number of issues associated with that. There would be a cost increase at the end of the day if you only had one fifth-generation fighter to procure and you had to do it under foreign military sales. There's an actual cost increase in the acquisition program, as I talked about in my opening remarks.
In terms of the actual process, a program of this magnitude and complexity would take several years, probably no fewer than four years. It would take tens of millions of dollars of support from Public Works, my own teams, etc. It's unlikely that it would be less than $20 million or $30 million.
I think the biggest costs would be that the global supply chain is being finalized now for joint strike fighters. They need to nail down who is providing what piece now and drive that into a very efficient production line to get the costs to be as low as possible as quickly as possible. They have clearly made the point that they wanted to nail down their supply chain by the end of 2010.
Waiting till 2013–14 to make a commitment would have potentially a serious effect on Canadian industry and its ability to participate, because unless you make a commitment to buy, you don't get to play in the industrial participation.
