If I understand you correctly, you're asking about communication north of the Arctic Circle with the F-35. First of all, we're operating our F-16s north of the Arctic Circle today with the same communication system that you will have in the F-35. That is unproblematic; it works.
What we do is send the communication, if you're operating in the far north, from one F-16 to another. We use this kind of system. As you know, the F-35 program, as one of its ambitions, is to have a system that can operate permanently and independently north of the Arctic Circle.
It will come at some time, but for the moment we will be using the same system as for the F-16. It works in the areas where we fly, and it's the far north.
I know that the F-18 of Canada has another system, which is a Canadian solution, but we have a system that works. It is kind of an artificial debate, I would say. We sail in the Arctic and we fly in the Arctic, and we have no communication problems that we cannot solve.
There are no fantastic solutions anywhere. You have to make compromises, but it works.
