Without going into any operational details of course, if say there was a mass attack on the UK by hostile aircraft, is there a plan in place to generate enough aircraft quickly enough to counter a threat?
Or do we just have our QRA aircraft plus any replacement aircraft in reserve?
I'm assuming that other NATO countries would be a tad interested in seeing, say, a mass formation of bombers heading towards the UKADR (from the East I was thinking), and act accordingly?
