NASA mysteriously trying to pull world’s fastest plane, SR-71 Blackbird, out of retirement — and won’t say why

Seeing Blackbird fly again after all these years would be incredible. I’d love to know what NASA has planned for it.

I like its lines, but realistically, I don’t know what you’d use it for unless you need extremely high-resolution images.

We know, from Trump’s probably-ill-advised tweet back in 2019, that we can do 10-centimeter resolution from reconaissance satellites like USA-224, near the physical limitations of light resolution.

en.wikipedia.org/wiki/USA-224

Perigee altitude: 270 kilometers (170 mi)[1]
Apogee altitude: 986 kilometers (613 mi)[1]

During missions, the SR-71 operated at high speeds and altitudes (Mach 3.2 at 85,000 ft or 26,000 m)

The SR-71 operates at a tenth to a thirtieth USA-224’s altitude, so assuming comparable imaging systems (which I could believe) and that there aren’t stability or thermal issues (which I’d be less-certain of) it can get ten to thirty times the resolution of a KH11 satellite from the lower altitude. I’m not sure how much utility there is in reconnaissance to getting 1 cm or ⅓ cm resolution images instead of 10 cm.

I can think of a couple of reasons to use the SR-71 again.

• Concern that a crash in space could lead to a cascade of crashes, disabling all sattellites.
• (On demand) capacity. I could imagine that the SR-71 can cover an unplanned spot faster than sattellites. Also, with the wars in Ukraine and Iran they’re maybe finding out that they don’t have enough imaging capacity.
• The imaging angle, a plane can image almost horizontally, they can look under bridges, through windows etc.
• A ten times increased resolution could be useful for recognizing details, maybe it’s even good enough to recognize people though it might be pushing the limits of facial recognition. It’s also the kind of resolution where they can read some text, e.g. identifyers on shipping containers or military vehicles.

the sr-71 is definitely not a scramble-able plane:

• it leaks fuel when on the ground (it shrinks when cold) so it’s stored empty,
• it’s as aerodynamic as a brick when subsonic so it needs an insanely long runway, and
• it has an always-on afterburner so it burns an alarming amount of fuel.

when they were doing surveys of iraq during desert storm they had to field a fleet of eight tanker planes over the indian ocean just so the damn thing would make it from japan to the gulf.

Edit: oh and those are specially designed tanker planes because of course it uses JP-7 so they needed separate tanks for that and their own fuel. they also needed to be able to refuel at like 850km/h or the blackbird would just drop out of the sky.

love that plane.

Iirc it starts nearly empty and is only fueled up in the air, so basically no way around tanker planes.
