the entire V bomber force did indeed have fatigue limits on the airframes, they were originally developed for a high level bombing role, however they switched to low level flight part way though their service which causes more stress on the structure of the plane.
the Valiant was the first of the three to break up in flight, breaking the main spar of the wing, due to fatigue, at which point they put a fatigue limit on them.
Told this in a previous topic so forgive me those that remember...my dad was instrumental in finding the fatigue damage in the Valliants....
No-one was aware there was a problem, he was doing some routine maintenance which involved getting access through a hatches and inspection covers etc. He got out and reported a problem he'd seen to his immediate superior. Within minutes it was going up and up the chain of mcommand. Bigwigs, suited inspectors, people from the Ministry, all progressively looking more and more worried. Within hours or days it was grounded, within weeks, the decision was taken to scrap the lot....indeed, the fatigue may have occurred anyway, but the change to low level flying accelerated its demise.
Co-incidentally, my dads twin brother was a crew chief in Vulcans (sounds awesome, can you imagine !!!!!!), and he was telling Dad on return from a training mission in the States, they'd done sone REAL low level bombing runs, comparing how the British compared with the Americans....apparently the plane bucked and jarred and shook like nothing on earth while it was at low level at high speed....the buffeting from the shock waves hitting the ground under the aircraft was frightening.
A sobering thought, as crew chief, escape from a stricken Vulcan for the crew chief was extremely hazardous, apparently the only 'safe' escape was when the plane was upside down.
Saw theRed Arrows yesterday in Peterborough. They were due 40 miles away in Duxford 5 minutes later....5 minutes, what a way to get around.
