At Nav School, on the shop floor it was business as normal, up the food chain there was a bit more consternation especially when they were talking of cutting the RAF to 57,000. We had some 90 instructors pushing through around 140 students per year. While you can halve the throughput you could not halve the instructor numbers.
Later, I was on a NATO committee and we set up NATO-wide simulation exercises. It was not until about 1993 that the need for these was questions.
Later still, at Coningsby we still practiced cold war fortress Britain scenarios with CAP manning, mass raids etc. There was a marked reluctance to look forward even after GW1. We (or rather the secret squirrels) hung on to the old war plans and TTW procedures years after the world changed and former WPC started to join NATO.
I suppose in some ways they were vindicated with the renewed Russian incursions into UK and NATO air space and the resumption of maritime ASW and ASuW for the Nimrod force.
But just how long do you hang on to obsolete documentation in case you can use it as a framework for the future? Units close, sqns disband, aircraft withdrawn, aircraft carriers scrapped and hardened buildings are chopped up.
Well it would have had we had a Nimrod force.
