Better off looking at companies like Marconi whose Avionics Radar and Countermeasure Systems is based in Edinburgh and, amongst other things, is responsible for the Typhoon ECR90 radar.....
Their portfolio is impressive when other projects are included - notably F35. I guess the infrastructure of what is basically an avionics company is reasonably mobile, even the production facilities - its the people that might not want to move, but then again perhaps the dedication and interest in the technology might be enough.
I wonder what points the SNP are looking to score. You can be sure they aren't likely to be wanting to praise recent defence policies or acquisition decisions!
