Those aircraft were developed in the EU, the Tornado project being launched while the UK was applying for accession.
When - and if - Britain leaves the EU, not sure the US will be pleased to see cooperation with some EU country continue.
What a load of guff. Are you suggesting the likes of BAE won't be able to work with European companies?? That'll screw the Gripen programme, not to mention Typhoon etc etc. Also, what of the F35? Plenty of European workshare in that.
