The figure we gave of $4,000 to $4,500 Canadian per hour covers the direct operating costs, which are basically the fuel, oil, all consumables, all spares, all first- and second-line servicing, everything you would need to operate the aircraft on and off base. The only thing we don't include there is the labour charge for off-base operation. There are too many variables there.
This figure is one you can use as a comparison. It's going to be the same metric applied to any aircraft. If you simply take an apples to apples, that gives you the comparison you need. How much does it cost to run this aircraft over 40 years? We say it's $4,000 to $4,500 per hour.
Sustainment engineering is a parallel activity, which would be done in this country, so we don't look at that. That's not a cost to you; that's part of your program, which comes with the Gripen aircraft. You will sustain and engineer your own aircraft. That's part of our commitment to you to enable you to do that.
