I think you may find that MRA4 never happens
long-range submarine hunting isnt deemed enough to keep the aircraft going
And your evidence for this is what exactly?
it is still deemed cheaper to get rid of it and shut Kinloss and the entire programme down
Cheaper than what exactly? Obviously if you scrap a system and close a base that will always make things "cheaper". You might just as well have said "its still deemed cheaper to scrap [insert programme here] and shut [insert stn/base here] and the entire programme down".
