I never knew those readiness states, all the years I was in. Wasn't worthy of being told. We were simply always either R1 or R2 and it was obvious we were.
6 ships out of the 19 in total must be at R1 or R2 then... Plus the 3 in post refit work up would eventually come into play. That's it and sounds about right on what I can see.
Proone no I'm just saying I wouldn't join now, and I would advise young people starting out in life to avoid a career serving in the UK armed forces. Because its:
1. Poor pay relative to what you have to do.
2. Limited career prospects in that it is continually shrinking in size and workforce.
3. Operates under dubious and challenging motives for its expeditionary war-fighting.
4. Aftercare if you cop it are a bit limited.
5. You are always available for political/ legal barter up to about 60 or 70 years after you leave (see 3).
and more..
Time and distance from when I served opened my eyes and increased the viewpoint. Now that I see the whole picture my advice remains do not serve.
