Orca - sorry still don't get it. As I understand it, if the money was spent on the C decision (which is confusing in itself because through life most claim the C is cheaper) then that will be with the expectation that the C is the GR4 replacement, surely?
Although I was told that JSF was part of the GR4 replacement well before the last SDSR as part of the 2 FJ fleet plan so it didn't matter if it was the B or the C, except the C is greatly superior of course.
