the point here is that the blackbird was too old,carried no weapons,wasn't built to be a fighter or interceptor and moreover when the MiG-25s were
around it had no problem in dodging them but with the arrival of the MiG-31 the game went upto a new level and the blackbird (i am sorry) just
couldn't compete at this level hence it became essential to take this expensive(its fuel was costlier than the costliest you can imagine) bird off
the skies and satellites could to the same job without any loss of human life

The arrival of the MiG-31 had nothing to do with the retirement of the SR-71. Setting the combat capabilities of the MiG-31 aside for just one
second, the simple fact is that for
decades the SR-71 has not intruded on Russian airspace, therefore the MiG-31 is not a threat. And since
the radically-downgraded export version of the MiG-31 is not selling, its not likely that any US recce aircraft would need to worry about bumping into
a Foxhound in the third world.
While the Blackbird possessed both speed and (limited) stealth, it also possess a tremendous (and highly classified) electronic warfare suite, which
severely degraded the electronics of Russian AAW and SAM systems. Do not blindly believe that all those SAMs fired at Blackbirds missed simply
because they flew too high and too fast - it was the comprehensive ECM suites, both barrage and self-screening, that allowed the SR-71 to have such a
damage-free career. Read up on the contributions that Adolf Tolkachev provided to the US regarding Soviet AAW and SAM radars, and you will understand
why the Blackbird was never shot down. As with most great jet aircraft, it's not the airframe or engines that make the bird - it's whats under the
skin that makes it great.
However, that all being said, I'm sure that any SR-71 pilot, given the opportunity, would wisely give any modern MiG-31 a respectfully wide berth,
given an encounter. You may be good at getting the Bear, but someday the Bear will, indeed, get you.....
I don't beieve that satellites provide everthing the Blackbird used to provide. And I also do not believe that UAVs are filling that gap either.
I'd say there is at least a 75% probability that there is a manned, XVLO platform that is quietly filling the gap that was created whent the SR-71
was retired. The Blacbird is simply too big (RCS-wise) and too expensive to keep in the air.
