Was just about to revise my previous, pointing out that everyone agreed that SDR 97/98 was actually a pretty good document - just never funded and made some poor assumptions about concurrency and duration of scale of effort.
The whole idea of that SDR was the "Expeditionary" capability which everyone agreed was post Cold-war and in general a good idea. All the expensive platforms now being tagged as "cold-war", with the possible exception of Typhoon, MRA4 and Astute were spec'd and ordered to fit that capability mindset.
Interesting to see "new-speak" (or collective amnesia) in action. The treasury have their tag-line sorted and no-one appears to be pointing out the obvious......
