It always seemed a poor idea.
Perfect for a Mallet Blow and the Hawks could CAP Croquet Lighthouse and have 90% of the muds coming past in sight.
Hard to Imagine the Soviets getting that close to the UK though?
If the Hawk was to be a light fighter surely would have been better going to Germany and running CAPs on the North Germany plain. Much more likely to bump into Soviet Tactical Aviation. (although perhaps not after what we see in Ukraine)
But I think the Hawk would have been much better in wartime being used for Emergency CAS – as Harrier Replacements/ Additions in Germany. Much the same as the Germans used the Alpha Jet. Although perhaps not a popular plan with any crews!
