Can anyone remember if the Tornado GR1 was fitted with mode 4 IFF during Granby, I believe the F3s were but I am interested in GR1. I am just asking as for my GR1 cockpit rig build I have just got a IFF controls which is from Tornado, I already had one but from what I can tell the one I have was an earlier version which does not have mode 4, the new one does and I have ben told that is thee type fitted to Granby jets, but I think the chap who told me was speaking as a F3 pilot or nav, so I am unsure if it was also fitted to GR1, it makes sense that it should be.
