It would have been retired anyways. The Cold War was long over and Satellites could do most of what the 71 could do. Drones were coming online and could provide real time Intel for extended periods. The BlackBird cost a fortune to operate and maintain, money best spent elswhere.

It, and especially the U2, probably prevented a nuclear war by keeping us informed about what the Reds were up to. I know because of the U2 Kennedy knew just how big our ICBM advantage was during the Cuba crisis and was thus able to call the Soviet bluff. Strange I was in the Mid East for 18 mos and the SR71 was very active in the region, not just the Mideast but also the Soviet missiles locations across the black sea, but I never saw a BB. U2's yes but not SR71s. We knew the tankers were going to fuel them because they used a special fuel only for SR71s.

The funny thing is U2's are still in service. In fact one (reported as a trainer version) just went down a couple of weeks ago killing one of the pilots.
I was fortunate enough to see a Blackbird in flight at an airshow back in the eighties. I live about 100 miles from Beale AFB. Beautiful aircraft, smaller than I had expected, but impressive non the less even at subsonic speeds.

I still can't believe I've seen one in person at the Air & Space Smithsonian when I was younger. Such a cool aircraft.

There are still U2s around too. One is based at Elington Field. I believe NASA uses it now. You see it taking off or landing sometimes.

I was working the flightline one day in the late 80's at Nellis AFB.  We got call on the mx net saying an IFE was inbound...no big deal happens almost every day.  The type acft was an SR-71...not an every day occurrence.  As the time for the ife acft to land pretty all maintenance on the flightline ground to a halt.  Folks lined up on the red line by the taxiway to watch this guy land.  Prior to landing we had to tow every jet out of the phase inspection hangar to make room for it.  The landing was uneventful, as the jet taxied up to the hangar the pilot chopped the throttles as it entered the hangar, doors quickly closed and SP's quickly surround the hangar.  A few hours later the aircrew were there allowing us to walk around the airplane(behind a red rope of course).  They answered what questions they could and the most common were how high and how fast.  The how high was "above 70,000 feet and how fast was "we cruise effortlessly mach 3".  Turns out the had a hyd failure shortly after T/O and air refueling over California/AZ border. Declared emergency over NM, descend and slow and turn over TX and land at Nellis AFB in NV.  Several days later the jet was fixed and even though it was a weekend, everyone went to the flightline to watch the launch.  They started up and taxied to the end of the runway to do the engine runups one at a time.  The takeoff was awesome, loud smokey, just awesome.  The acft did a closed pattern around the base so we could see it in flight.  The next pass was quite possibly one of the most amazing things Ive see a jet do.  They lit the burners prior to passing over the runway, at about mid field they pulled into a climb that could only be rivaled by a rocket.  This thing went almost straight up, accelerating until it was a tiny black speck in the sky. We would talk about it in the expediter truck for the following week, was just crazy.

A good read is Ben Rich's book called Skunk Works: A Personal Memoir of My Years at Lockheed.
Lots of interesting info in that book.

Anyone want to take a guess why the F-117 was a faceted low radar cross section design and the the B-2 was a smooth radar cross section design?

Computers.

3D CADCAM design wasn't around the the F-117 was designed on computers limited to 2 dimensional (with layers)
