    The general tone here seems to be against the effort, but separate the circus from the ringmaster and there is a lot to like here.<p>Having a manned, very high altitude, very fast research plane is undoubtedly useful for all sorts of development purposes.<p>But more than that, we <i>are</i> as a civilization doing a bad job of preserving cutting edge expertise from the past. We keep letting entire areas of engineering and technology die out without really trying to preserve them even though we know at some point they will come in useful. The skills, processes, even institutional confidence developed in just trying to get an SR-71 flying again will teach us a lot about resurrecting other such dead ends. Aerospace in particular is full of them. That will, for sure, get us out of trouble or speed up something we need at some unknown point in the future. I&#x27;d think of it more as developing a general capability than the world&#x27;s most expensive vintage aircraft hobby.

      Look, I&#x27;m certified as the world&#x27;s biggest SR-71 fan. As a kid, I saw it fly a number of times, got to see it up close, and had a family member who worked as an engineer on the program. I believe it may have even been <i>this</i> Blackbird, 844. It impacted me so much that I later went on to work on my own black and other military aircraft.<p>I&#x27;m assuming that, if this rumor is true, somebody in the Trump campaign forced somebody at NASA to do this out of some misguided nostalgia. My hope is that if they&#x27;re going to resurrect the Blackbird, they&#x27;ll at least retrofit modern engines into the thing.<p>But there are much more modern, cost-effective ways to build very-high-altitude, very-fast aircraft. I&#x27;m doubtful that going manned is the right approach. It takes a lot of weight and space to carry a person and the required life support systems. That capacity could be better utilized for more fuel and sensors.<p>There&#x27;s better technology that&#x27;s far cheaper to maintain and operate. And you could potentially get hypersonic, or at least near-hypersonic, performance.

        &gt; My hope is that if they&#x27;re going to resurrect the Blackbird, they&#x27;ll at least retrofit modern engines into the thing.<p>Question for people who actually make the engines: is this idea feasible? Like, at all?<p>I always imagined a plane&#x27;s engines to be very tightly coupled to its electrics. In my mind, even if the wire harnesses somehow lined up right, the signals inside would be talking totally different languages.
        • runjake16 minutes ago
          There&#x27;s standards for signaling like this. One being MIL-STD-1553. Another being ARINC. And you&#x27;re now seeing a lot more Ethernet and such.<p>Normally, the engine itself uses proprietary signaling for its systems internally, but will present a standardized interface to the avionics.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;MIL-STD-1553" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;MIL-STD-1553</a>

          The two things that make or break an airplane are the engines and airframe. Everything else can be swapped out. As long as the airframe can support the engine, structurally and aerodynamically speaking, there are no issues. Wiring and avionics can all be easily replaced. The control systems for the plane can be reworked too.<p>GP is correct, this is a plane designed almost pre CFD, a clean sheet design would go much further than this. They are missing out on half a century of material science advances.

            The Navy has been pushing for a large cruiser for literally decades now. The Trump-class is that under a different name. We&#x27;re at the end of what we can cram in a hull that&#x27;s nominally called a destroyer, especially if you want to host larger hypersonic strike weapons and ABM interceptors, plus the radars to manage the ABM battle.

          I never saw extraterrestrial technology or any indication of extraterrestrials existing, other than gag stuff in hangars.<p>All the aerospace technology I&#x27;ve ever worked with or heard of has a pretty clear (human) engineering lineage. None of the planes you&#x27;ve seen or heard of, or parts thereof, are based on extraterrestrial technology.

        Hopefully it won’t be leaking fuel anymore with modern engines
        • SoftTalker1 hour ago
          IIRC the fuel leaks on the ground were because the sheet metal was all fit rather loosely to allow for expansion in flight. At the speeds it would fly, the skin got quite hot.
        • krisoft58 minutes ago
          But it is the fuselage gaps which was leaking, not the engines. After the elastomer filler broke down due to heat cycling. They needed the elastomer because the fuselage was heating up during flight which made it expand.<p>I&#x27;m sure we could &quot;fix&quot; it. But changing the engines doesn&#x27;t seem to be the right way to achieve that.

          You&#x27;d probably be using some mix of better turbofan&#x2F;turbojet engines along with ramjets&#x2F;scramjets. So, yes.

        &gt; I&#x27;m assuming that, if this rumor is true, somebody in the Trump campaign forced somebody at NASA to do this out of some misguided nostalgia.<p>Came here to say this is exactly my guess.<p>FWIW I think it&#x27;s almost always a good idea to keep at least one example of any plane flying, just out of simple cultural principle (I feel this way about the Avro Vulcan and I think it&#x27;s really sad that none can do more than taxi anymore) so I am not sure it&#x27;s <i>stupid</i> for them to ask, but I can see why keeping an SR-71 in any kind of functional condition might be implausible.<p>I would guess this is not a serious project to get it flying, but more a recognition that it will take more than two years to do it, could be cancelled at the two year mark without really wasting vast amounts of money, and ensures some very easy, regularly replenishable goodwill from the man who thinks the USA has planes that are literally invisible.<p>There is precedent, after all: his insistence on a return to steam launchers on carriers.

    A couple of questions&#x2F;observations:<p>1) when people say &quot;destroyed the jigs, tools and spares in 2007&quot; What do they actually mean? Burying things isn&#x27;t destroying. Putting them in a furnace is destroying. Is it possible that both parts, and tools actually are recoverable e.g. from the seabed? The dimensional stability might be off, but to help reconstruct tools, it&#x27;s not nothing. Likewise digging up something buried in its packing crate is not rocket science.<p>2) &quot;that would be ludicrously expensive&quot; doesn&#x27;t mean much any more. It&#x27;s not unlike &quot;we can&#x27;t make a saturn 1 any more because the tools were destroyed and it would be ludicrously expensive to make an F1 engine&quot; -well yes, but thats not impossible, it&#x27;s just unlikely and expensive. So maybe this is unlikely, expensive but ... has a unicorn sugar daddy?<p>3) there are craft in all sorts of places. Not just on sticks outside NASA property. I am not a historian or a federal government employee, but I wouldn&#x27;t think it impossible for people to ask other agencies to let you inside the shell and remove the bits you want, or even ask for it back. The one on a stick in Balboa Park San Diego might have associated boxes of bits-and-bobs..<p>4) its a titanium alloy. It&#x27;s temperature and corrosion resistant, noting some things (like chlorine according to the web) are bad for it. It&#x27;s not made of pure chinesium or balsa wood. Interior surfaces would be in pretty good shape.
    • Beretta_Vexee6 hours ago
      So titanium alloys are not completely resistant to all forms of corrosion. They are particularly prone to galvanic corrosion, which means that specific tools must be used, all forms of ferritic contamination must be avoided, special tools must be used, and they must be stored separately, etc.<p>This is very labour-intensive, which is why it is generally carried out in dedicated workshops, with specialised equipment, and so on, by staff who have been specifically trained and do nothing else.<p>If you add jigs, production-specific tools, and so on, all of that has been lost and needs to be recreated: staff need to be trained, QA defined and workshops need to be reorganised. This can take decades to return to the expected standard. You can throw as much money at this sort of problem as you like without actually being able to speed things up.<p>Finding the drawings and dimensions is the easy part of reverse engineering a mechanical device. The real challenges lie in identifying the manufacturing processes and quality control procedures, and achieving the expected performance with an acceptable scrap rate.<p>If I place a monocrystalline turbine blade on your desk, you’d be able to draw up the plans for it. But that would tell you absolutely nothing about the processes required to produce a monocrystalline ingot of a nickel superalloy.<p>Source: former mechanical engineer in the nuclear industry, managing obsolescence was one of my day-to-day tasks.

        &quot;decades&quot; is a stretch.<p>The original A-12 took 4 years (or less) to design and build from scratch with slide rules and manual machine tools.<p>Surely we can match that with our 70 years of advanced knowledge and equipment?<p>Maybe our risk tolerance is low now, and we don&#x27;t have Kelly Johnson.
        • Beretta_Vexee2 hours ago
          The A-12 was not developed from scratch, whether in terms of its design, production facilities or in-house expertise.<p>Design is a very different matter when you have a workshop full of skilled workers and machinery right on your doorstep, who can critique your work and explain what they can and cannot produce. A lot of engineers discovered this the hard way when companies started outsourcing to the other side of the world and lost control of production process.<p>Designing parts that look nice but are impossible to machine or assemble is simple.<p>Designing the plane may only have taken four years, but training the staff, organising the workshops and mastering the production tools took much longer.<p>Just look at the struggles faced by all the organisations that stopped producing anything for a long time and then wanted to restart production. Whether it’s ships, aeroplanes or nuclear power stations, each time it takes something close to ten years to restart.<p>When they manage to do so.
          • dingaling2 hours ago
            &quot;Designing the plane may only have taken four years, but training the staff, organising the workshops and mastering the production tools took much longer.&quot;<p>Lockheed had no experience with titanium prior to OXCART. 95% of the first 6,000 sheets of titanium had to be scrapped.<p>It was the first production design to incorporate low-observable shaping.<p>It was 50% faster than anything Lockheed had previously tried to build, and four times faster than the U-2.<p>And they literally did all that between April 1958 and April 1962.<p>So, yes, it was designed from scratch as nothing useful from prior projects read across to it.
        • Merad1 hour ago
          The A-12 was built in an era when the aerospace industry was flush with knowledge and active R&amp;D into mach 3+ flight - everyone was convinced that it was the future. Today&#x27;s industry is heavily optimized for subsonic airliners and fighter jets that have top speeds of &quot;only&quot; mach 1.5-2. No one in the west has built a mach 3 aircraft since the 60s and not in Russia since the early 80s. The knowledge isn&#x27;t _lost_ (well, we hope) but there is a lot that will need to be relearned, and we all know how even the best documentation is usually missing a lot of details.
        • j4k0bfr2 hours ago
          Not a mechanical engineer here, but I reckon close to a decade would be pretty realistic for full operational restoration. Even a small amount of lost critical maintenance knowledge could cost the whole airframe.<p>I&#x27;d compare it to a really old codebase. Sure, our modern tech is much better. But if you need to make an old, top-secret COBOL program work as-is, you&#x27;re in a pickle. Sure, we could rewrite it in Rust and make it way better, but management sees it as more cost-effective to just &quot;turn the old one back on, it worked great!&quot;. And unlike software, it&#x27;s pretty hard to comprehensively test a plane in a non-destructive way. Bolt falls off turbine while in flight, etc etc. Losing even a single SR-71A airframe would be a massive headache, methinks.

          Risk tolerance perhaps? But also our increased capabilities make it harder to keep things simple. Should it be radar-opaque? Of course! Capable of autonomous flight? Duh! Carrier landings? Well sure, that might be needed. Refuel midair? Obviously. Sigint to the gills? Seems useful…

          Complexity and knowledge grow over time. It&#x27;s likely that the last SR-71 and the processes and materials behind it were much more complex than the first. You have to recreate not only the first unit, but decades of added knowledge, skill, and complexity.

      • Beretta_Vexee6 hours ago
        &gt; with CNC and robots we can achieve far superior results for a fraction of the cost.<p>This is only true for mass production, where the set-up costs are spread across thousands of units. For small batches, the cost of automation often exceeds the cost of the batch itself.

          Still, I don&#x27;t think anyone is ever going to hand assemble thousands of tubes for nozzle cooling &amp; prepare them for brazing.<p>Not when you can get the same for a fraction of the cost by CNC milling the channels &amp; then shrinking a jacket over it.

          • Beretta_Vexee2 hours ago
            The assembly of the tube bundle in a nuclear steam generator is still carried out mainly by hand, using hundreds of shims, anti-vibration bars and supports.<p>At the other end of the spectrum are stamped-plate heat exchangers, which are mass-produced using a press line.<p>Each has its own specific application, and they are neither comparable nor interchangeable.

        Just to clarify one thing, Edwards AFB still has a lot of those highly-skilled engineers<i>. Edwards has a huge machine shop with all the fancy tools and the engineers in there job is mostly making one-off replacement parts for planes. NASA and the Air Force are still flying all sorts of test planes out there and they often need some part they can no longer get from the manufacturer. They drop the spec for the part and it gets made, sometimes it takes a long time, but I promise there are skilled people on that base who can make it.<p>IMHO the SR-71 is going to be problematic due to sourcing the materials and fluids more than finding skilled CNC techs.<p></i> source: worked on Edwards for several years
        • jjuel1 hour ago
          No doubt there are highly skilled engineers there, but saying &quot;those&quot; might be a stretch. It is possible someone there has worked on an SR-71A, but it last flew 27 years ago. It was originally introduced 60 years ago. A lot of the knowledge about this plane has most likely unfortunately passed on. That isn&#x27;t to say people can&#x27;t learn, but it is a tougher starting point. Honestly, almost like starting over I would guess.

        &gt; with CNC and robots we can achieve far superior results for a fraction of the cost<p>As far as I know that is still not true. Manual welding provides less defects and higher quality welds. Provided one has experienced welders. The cost is much lower for robotic welding but the results are still not as good as manual welding.<p>&gt; Those skilled people retired (and by now died) without a replacement, because the job had become obsolete.<p>The skills can be acquired by new people.<p>Regardless I believe the industry has moved to 3d printed parts for engines due to lower costs, higher throughput. And in either case rigorous inspections are the way to get reliable parts.<p>I do agree that they cannot build a new F1, but they can build a new better model. But I believe that has to do with engineering and the loss of the contextual knowledge and experience building these things, the loss of why the design settled at what it did, why the processes settled to the ones documented, the undocumented knowledge the people building these had.<p>This knowledge can be rediscovered, but it would be easier&#x2F;cheaper to start with a new design and acquire that knowledge organically.
        • bluGill3 hours ago
          &gt; The skills can be acquired by new people.<p>They can be. However it will be expensive to train them. (starting with figuring out what training is needed - probably a lot of trial an error because not all of this was written down) Also you will need to pay people to get this training - they won&#x27;t pay for it themselves since it is unlikely to be a useful job anywhere else anymore so they have better investments in their time&#x2F;money.

        &gt; The bigger problem there is that we don&#x27;t have the people any more.<p>You don&#x27;t have the education system and work ethic, stable family, curiosity. Many young people feel college is a waste and YouTube or AI has all the answers. Children in schools even now in 2026 right up to high school and even college can&#x27;t read. Many who can read can&#x27;t comprehend what they are reading.<p>In addition to that I recall a UK study that said smartphones have caused a lack of hand dexterity. Not social media or content but the phone itself a two dimensional surface means hand dexterity is not developed. People do not have hobbies like wood working, sewing, anything that involves fine manipulation and strength. The biggest hit is to the medical field and lack of surgeons because people in medical school now do not have fine motor skills needed for the job.

Many young people feel college is a waste<p>I think a lot of this has been driven by businesses completely dropping their part of the deal in a pursuit of ever increasing profits. Formerly there was the long term promise that staying with one company would be rewarded and instead now for 99% of companies you&#x27;re deeply punished if you don&#x27;t hop jobs every couple years for a pay bump. Then they&#x27;ve also lobbied to completely gut funding for education to lower taxes or shift into subsidies. And a lot believe college is a waste because there&#x27;s been a huge reduction in the value of just holding a college degree while the costs have ballooned.<p>The whole system that created it has been dismantled for profit long before the culture of it started to fall apart.

      As far as number one goes, the tooling has almost certainly been recycled when they say &quot;destroyed&quot;. By recycled I mean in to new steel in an electric arc furnace. It&#x27;s pretty common even in every day mass production for tooling to either be sent for destructive testing or a destructive decomissioning&#x2F;EOL use (cutting, defacing, used for practice for facility apprenticeship, etc). I imagine something on the level of Blackbird tooling would have gone through a very strict decomissioning process before it even hit the scrap bin.<p>As far as #2 and the rest goes, I agree that with enough money you could make anything happen. However, sometimes recreating something so complex could be a &quot;not enough money in the world&quot; type situation. Sure, drawings and specs exist, but even on today&#x27;s 3-d modelled assembly you&#x27;re not typically modelling every single part to full accuracy. You have things that are off the shelf that might be a black box drop in, you have things you contract out that are built to spec. You know what you get, but not necessarily exactly how it&#x27;s done. Then in your own facility there is a certain level of institutional knowledge that is not necessarily documented in such a way you can just recreate it.<p>Finally, one of the biggest hurdles, there&#x27;s are not things that you can just throw an LLM and some engineers at. The actual trades themselves have changed so much since the time of production your only option is to call in retirees. The machinery is different now and so are the workers.<p>I feel like with a large budget they could definitely get an SR-71 in the air for testing and exhibition purposes, Id love to see it happen. I guess it really depends on how much was removed and destroyed when the machine was decomissioned and how much damage lack of maintenance, environmental factors and age have taken their toll. The good news is it hasn&#x27;t been operated in a long long time. The bad news is it hasn&#x27;t been operated in a long long time.<p>Source: I am a toolroom machinist at a material science lab in the aerospace and defense sector.

        Large production runs (think cars) the tooling is sold to a third party to make spare parts. However that third party will watch what sells and scrape the tooling when sales are not large enough to justify keeping it around. Things that never break have the tooling scrapped early. Things that collectors break the tooling stays around - if it wears out they make replacement tooling.<p>The SR-71 was not made in large enough numbers to get the above treatment. If the government wants spare parts they need to pay to keep that tooling around.

    This fills me with monumental amounts of joy and excitement. Especially being young enough to only know about the Sr-71 through stories and pictures, it would be incredible to see it in the air again.<p>Reading through that article makes it sound like NASA has very high ambitions without a very concrete plan which worries me, I hope that management takes the approach of actually listening to their engineers instead of just assuming they can do anything. I mean they are NASA engineers they can probably do anything but ykwim

    The Blackbird is a deeply awesome machine, and hn understandably loves it. But this initiative is almost certainly about agency funding and access to budget, not engineering.<p>The Orange Entity sets the direction and his congress provides the money. My guess would be that NASA has been told that the direction that leads to there being money is to forget the space telescopes and other science, and instead to focus on national prestige projects (Moon, Mars) and things that will feed through to military applications (hypersonic flight).
    • j4k0bfr2 hours ago
      Agreed, I can&#x27;t imagine much scientific&#x2F;engineering value that NASA would get from restarting the SR-71A by itself. There&#x27;s an easier way to simulate the Blackbird&#x27;s flight characteristics without having to magic the damn thing back into the sky.<p>I reckon it&#x27;s much more likely to be used as part of a training program (maybe related to the shiny new F-47?) or for destructive&#x2F;non-flight testing and research.

    &gt; The Air Force and NASA destroyed a $600 million supply of spare parts for the Blackbird fleet in 2007. The move came long after it seemed unlikely, if not impossible, that an SR-71A would return to operational service.<p>There&#x27;s also the issue of converting a tanker back so it can carry the SR-71&#x27;s unique fuel again. And for that matter, making a supply of JP-7 again. No other planes today use JP-7.<p>&quot;It&#x27;s not my money!&quot;

      That seems reminiscent of the Fogbank material in the US nuclear weapons. The process of making it was lost, and when it was finally recreated modern processes where to good and it still didn&#x27;t work.

      it looks like it would be much easier to get a powerful regular fighter jet engine (even old Mig-25 engines were fine for 2.8M), stick it to pilotless frame and just launch. Work a bit on intake shape, modern materials, CFD, and probably you can push it well into 3+.
      • justin662 hours ago
        Building a machine that can travel at speeds exceeding Mach 3 for a brief period of time is probably well within aeronautical engineering&#x27;s current capabilities, with today&#x27;s engines, yes. The innovation with the SR-71 was that it could fly at those speeds for an hour and a half, thanks in part to that JP-7 fuel with its high flash point.<p>Either way it&#x27;s unclear why NASA, with its decreasing budget, might feel like they need to be taking this on as a research project.

        The SR-71 wasn&#x27;t randomly retired, though. The tactical need to go really fast at a high altitude disappeared because you can now get the same intel from satellites and stealth aircraft. The real question is why do you suddenly need that capability again?

      I would not be so sure, the environment that led to the development of the SR71 is not there any more.<p>For one thing space based observation is very good and has a much faster turn around now days.<p>Back then photography was film based, satellites would fly take pictures and release the film in a pod to reenter and be recovered mid flight[1].<p>And on the other hand altitude and speed does not buy as much survivability as it did back then.<p>Fighters flew at a maximum of 1.5 mach and missiles at 2-2.5 mach.<p>S-400s for example can launch interceptor variants that can intercept targets at almost a hundred thousand feet moving at 14 mach. I know that is for ballistic targets, but I doubt an aircraft flying at a similar altitude even at hypersonic speeds would have much luck.

        The SR-71 is mostly analogue. It has remarkable battlefield resilience including ability to operate when EMP and nuclear radiation are issues that would affect a lot of digital systems.<p>Worried about how to navigate if the GPS systems gets knocked out by an adversary? SR-71 has an analogue system, use that. Worried about how an adversary could use cyberwarfar against your avionics? SR-71 has you covered, use all of that.<p>And sure, you could take all the designs and hand them over to the SR-72 team at LM and say &quot;yeah, all of that please&quot;, and they could figure it out, but you know what might be handy? A working SR-71 they could play with. And who knows, maybe the answer is to take an SR-71 in its entirety, and just upgrade a few parts to get the SR-72 performance (Mach 6) that you&#x27;re after.

          Side note: IIRC a lot of the star tracking tech still exists and is used by Trident D-5, B-52, B-1, and B-2 etc. IIRC.

      I suspect everything comparable of late has been orbital, which begs the question what is it they’re worried about with orbital? Satellite warfare is already accelerating if the rumors are true, is it that this is untouchable still? Is there some new camera sensor where eliminating that extra atmospheric diffraction or slowing down (lol) is needed?
      • walrus0115 hours ago
        I am sure that the orbital capabilities are also vastly improved from what the public has ever seen. But I think there&#x27;s likely a high degree of tactical value in having something that can keep station over a certain active conflict area (as an RQ180 can, maybe flying in a racetrack pattern at altitude, with sensors aimed down).<p>If you&#x27;ve ever seen the publicly released videos and audio of an RQ9 operator in communication with ground units watching the activity of a group of men&#x2F;vehicles on the ground, in live real time, something like that.<p>As compared to periodic revisits by LEO orbit satellites that don&#x27;t maintain persistent live coverage, or the extreme distance and data acquisition problem that aiming sensors in geostationary orbit at a 10x10km target area might pose.

          The problem is that &quot;can loiter over an area&quot; and &quot;SR71-like&quot; are fundamental contradictions.<p>The whole point of the SR71 is to be <i>stupidly</i> fast, to the point of being impossible to catch. It could outfly missiles, and the mission was done and over by the point anyone could scramble a proper defense. Have it fly circles over a target and you&#x27;re negating its one main unique selling point.<p>Want to loiter over a target? Use an RQ9. Want an impossible-to-stop snapshot camera? Use a satellite. So what&#x27;s left for the SR71? I guess there are some missions where 1) you don&#x27;t have air superiority, and 2) the target can hide in time from well-known satellite orbits, but 3) the target <i>can&#x27;t</i> hide with 15-minute warning from a plane - but are those <i>really</i> common enough to justify the massive investment it&#x27;ll take?

Please read the comment I replied to and what I wrote again.<p>The RQ9 is fine to loiter over and watch an area that has little to no air defenses, more stealthy things are needed if there&#x27;s some form of credible air defense.

          There are satellites in geostationary orbit that have realtime live feed and agile pointing capability. However, besides the SAR, RGB style observations are limited by clouds, and also you can’t switch out the sensors on a whim.

Ever seen a diagram of a Boeing (Hughes) 702 series satellite bus and antenna system built for L&#x2F;S-bands like frequency ranges similar to those used by Thuraya, Inmarsat and Iridium handhelds?<p>It&#x27;s widely accepted in the commercial two way satellite telecom industry that the NSA has comparable things with big unfolding umbrella-like antennas in geostationary which serve a similar purpose for signals collection.

                &gt; It&#x27;s widely accepted in the commercial two way satellite telecom industry that the NSA has comparable things with big unfolding umbrella-like antennas in geostationary which serve a similar purpose for signals collection.<p>How does that even work, do people just accept that their satellites hang around suspiciously close to other geostationary satellites and hoover up the very edge of the beam somehow?<p>Because if you&#x27;re transmitting stuff *to* geosynchronous birds you have to aim pretty accurately.
                • walrus018 hours ago
                  Handheld S&#x2F;L-band things like Thuraya, Iridium, Globalstar, Inmarsat phones don&#x27;t transmit in a very directional way at all. Or things like a Garmin inreach that have an Iridium modem in them. They&#x27;re omnidirectional enough that the broad requirement for a user is to be outdoors with a good view of the sky.<p>If you have a NSA-type geostationary satellite somewhere in approximately a 1&#x2F;5th arc of azimuth along the equator of the earth that can &#x27;see&#x27; an area on the ground, with antenna systems aimed at the area of interest (let&#x27;s say, Afghanistan), it&#x27;s not necessary for your NSA satellite to be anywhere close to the actual service provider&#x27;s satellite.<p>Note that Thuraya BGAN-like devices and handheld phones talk to geostationary, Iridium is LEO (but likely some combination of LEO, molniya orbit and geostationary can &quot;sniff&quot; it), Globalstar is similarly LEO in its service provider architecture, and Inmarsat is geostationary.<p>Also lots of conjecture out there that sigint platforms exist which are good enough to capture ordinary handheld device cellular traffic or VHF&#x2F;UHF radio traffic that&#x27;s not intended by its users or terrestrial operators to go into space at all. This is probably done from a combination of low earth orbit platforms and more complicated orbits or what we would call MEO (maybe about the same height as an o3b satellite?) to achieve longer dwell times over an area of interest.
                  • ErroneousBosh7 hours ago
                    But then with the difference in distance from LEO stuff like Iridium (RIP - I actually saw the ground flash of an Iridium flare once!) you&#x27;d need a truly *massive* antenna to hear that out at geosync.

                      An Iridium 9555 handheld phone talking to Iridium satellites in LEO with its antenna extended transmits in approximately the same frequency range and about the same tx power as an inmarsat isatphone 2. The former is LEO, the latter talks to geostationary.<p>Same concept for an Iridium 9555 or its successor in a dock plugged into the small coaxial cable that goes to the external hockey puck sized antenna.

        Satellites are defenseless and easily shot down, either one by one using ballistic missiles or by creating a sweeping ring of debris, in a full scale WW3 where things like treaties and sanctions don&#x27;t matter
        • wafflemaker8 hours ago
          Pluss any fuel costs 100x the fuel mass on launch.<p>So you&#x27;re sitting in your orbit and any changes (especially so close to the massive body) are super expensive. Which means sending anything after you must be pretty trivial (once the missile is already in orbit).<p>Spaceship just launched 30+ starlink v3 sats on its first orbital flight two days ago. It might as well have been flat disks of missile sats, even multi missile per each disk. Sitting there waiting, getting energy from solar, only having to expand fuel when a strong solar storm temporarily increases atmospheric drag on LEO + some minimal station keeping. A missile type sat with completely different budget for fuel and mass has a big advantage.<p>Maneuvering for a rendezvous (intercept), given 5-40 hours time, is very cheap in terms of ∆V (fuel used).
          • numpad01 hour ago
            More like, you can just launch couple rings of sand into the polar orbit of Starlink altitude ranges. It&#x27;ll wipe them all off like a window wiper over few days or so. Or the killer sat could have thrusters to rendezvous with each one, but it&#x27;ll be more complicated with the size of Starlink constellation.

            &gt; Maneuvering for a rendezvous (intercept), given 5-40 hours time, is very cheap in terms of ∆V (fuel used).<p>Only if you&#x27;re in approximately the same orbital inclination. Plane change maneuvers once in LEO are very expensive in delta V.
            • dotancohen7 hours ago
              The attacking bird needs to raise apogee to GEO anyway - after that the plane change is relatively cheap. They might not even raise perigee.
              • walrus015 hours ago
                I was replying to a comment where the person was talking specifically about LEO. Interfering with things in geostationary orbit is a whole other question.
                • dotancohen4 hours ago
                  Even for LEO. Plane changes are expensive - and you&#x27;ve got to then wait potentially many orbits to get a collision. To shorten that timeframe you&#x27;d change your apogee or perigee anyway.<p>Raising the apogee, then changing the inclination there is relatively cheap - and you can adjust the plane change and apogee to time a collision. Remember - there is no need to recircularize. Just collide. If the goal was to recircularize then I don&#x27;t know if raising the apogee would be worth it, maybe for extreme cases. But not for a collision.

        The SR-71 is because they need to test for speed.<p>That serves a huge number of things both offense and defense: engagement, radar, missiles, trying to boost the speed capabilities of new planes &amp; weapons.

        If those tic-tac videos were actually a classified aircraft, those airmen would have signed an NDA before they left the carrier.

      I&#x27;ve suggested this elsewhere in this thread, but the analogue nature of it might be useful to current design teams to get familiar with operationally.<p>Getting contemporary knowledge of the navigation, hydraulic, avionics and other systems is going to be pretty powerful if you need to build something that is as battlefield-ready in the modern era. Nobody is hacking into an SR-71, and it&#x27;s going to be delivering its missions just fine if GPS is knocked out. Taking the operational (and not just academic) experience of doing that and putting it into the current generation of Skunk Works engineers is going to be useful.<p>I&#x27;m not sure their plan is to put it into active service, but they could - the SR-72 could just be an SR-71 with upgraded engines and other systems.<p>However, the process of getting it ready for active service even if just as a flying museum piece could sure help a lot of engineers learn a ton of lost knowledge.

      I&#x27;d wager a plane in a museum is stripped down internally and nothing more than a shell, while a plane on an actively protected military installation is more likely to be complete (or more complete), thus easier restorable.
      • pwg1 hour ago
        The SR-71 on display at the Udvar-Hazy branch of the Air and Space Museum located near Dulles Airport in Virginia does not have its engines in the nacelles. The rest of the exterior looks complete, but other internals could very well also be missing and the exterior would still look identical.

        The opposite usually. Museums are sticklers for originality. They&#x27;ll bribe some congressman&#x27;s mistress to get a meeting so they can get assurances the ATF will behave &quot;favorably&quot; so they can import part of a half parted out anti-aircraft system from Chad ur Uruguay or some shit because that&#x27;s the only place the obscure gun variant they need for the coaxial machine gun in their tank is still available. Or they&#x27;ll buy the fuselage of some obscure plane that was only sold to the Indian Coast Guard because it shares all the cockpit instrumentation with some 100 series fighter they&#x27;re trying to undo the &#x27;nam era mods to and restore to it&#x27;s 1950s SAC trim.

      The Russians apparently fessed up after the cold war that they knew of the SR-71 project from early on, but the only thing they knew about it in the early stages was that beautiful and distinctive outline.<p>The Skunk Works team knew when Russian satellites were coming up over the horizon, and so would hide the early development models they had on poles and so on. They obviously didn&#x27;t want them to be pictured. However the satellites had heat-sensing cameras and so could see the heat differential the model had left as a shadow on the ground just minutes before. The Russians therefore knew there was a new plane in development, and they knew what the outline of it looked like, but nothing else for quite some time.<p>I bet when they first saw it, they agreed - a heck of a beautiful machine, one of my favourite aircraft of all time.

  • 0xbadcafebee15 hours ago
    To give you an idea how ridiculous this is: to start each engine, they made a cart out of two Buick V8 engines tied together - so four V8 engines to start the plane. Those V8 engines were long since out of production, so at one point they went around the country, to every junkyard, buying up every one of those V8s they could find, so they would have spares to start planes up in different places. If an SR71 had an issue and landed at an unusual airport, they had to fly the start cart and other equipment to that airport to start the plane again. Everything about this plane is expensive and one-of-a-kind. It&#x27;s a hot rod that goes to space.
    • AnimalMuppet15 hours ago
      Rather than re-engineer the cart to use a different block? I mean, I guess when a part reaches end-of-life, your first move is to buy as many as you can, before you try to re-engineer things so it isn&#x27;t needed, but... horsepower is horsepower. Torque is torque. It shouldn&#x27;t be that hard to replace...
      • jauntywundrkind13 hours ago
        They did eventually replace the Buicks.<p>&gt; <i>The original design was conceived by two Lockheed Skunk Works engineers who had prior race car engine knowledge. In the mid-1970&#x27;s, the engines of the start carts was changed to Chevrolet LS-7 454&#x27;s. The Chevrolet big block engines developed 465 horsepower each. Even so, for many years they were still referred to as the Buick&#x27;s.</i><p><a href="https:&#x2F;&#x2F;www.thesr71blackbird.com&#x2F;Aircraft&#x2F;Engines&#x2F;starting-the-sr-71-blackbirds-j58-engines-ag330-start-cart" rel="nofollow">https:&#x2F;&#x2F;www.thesr71blackbird.com&#x2F;Aircraft&#x2F;Engines&#x2F;starting-t...</a><p>And eventually the start carts themselves got replaced.<p>&gt; <i>In the &#x27;80&#x27;s the AG-330 Start Carts were mothballed and in there place came a Pneumatic Air starting system for the SR-71&#x27;s. It is true that the start carts were hard to maneuver around. Logistically, a recovery of a Blackbird at another base could be done easier with Pneumatic Air.</i>

          Yeah, big car engines is actually not that impressive, rather surprisingly primitive.

        Can the plane just carry....the starter ?, it&#x27;s another 200-300kg of payload, may affect the max range, etc, but much more convenient.
        • ssl-36 hours ago
          It could have, sure. That would have been easy. But it would have added weight and complexity. That would have reduced speeds and&#x2F;or altitude and&#x2F;or range between in-flight refuelings.<p>We fixed it the other easy way: In the event that an SR-71 makes an unscheduled stop somewhere that wasn&#x27;t prepared for it, then we send out a bunch of dudes with a cargo plane and some starter carts. That just takes <i>money</i>, which even easier.<p>It also takes time, but time was not a big deal: The plane was going to be there for awhile anyway. It could go over 15,000 miles between takeoff and landing; it wouldn&#x27;t have landed where it did if it weren&#x27;t broken somehow to begin with.<p>It&#x27;d need repaired by the crews who actually knew how to work on it -- who would also need flown in.<p>It would also need fuel before it could leave. That&#x27;s problematic since the JP-7 it required was shared by ~nothing else in the sky, so: More deliveries.<p>Waiting for some Buick V8 starter carts to be delivered from the other side of the world wasn&#x27;t really a roadblock at all.
        • scrumper1 hour ago
          There&#x27;s a bit in the Skunkworks book that talks about added weight costing significant altitude. I don&#x27;t have my copy in front of me but it&#x27;s quite a severe tradeoff: some fairly small amount (100kg perhaps, might even have been less) reduces ceiling by 1,000&#x27;.
        • pwg1 hour ago
          For military planes, every bit of weight you can shed up front increases some operational capability of the plane. In this case, not carrying an extra 200-300kg of weight for starters meant 200-300kg more spy equipment &#x2F;could&#x2F; be carried along on the mission.
        • joha42708 hours ago
          Most jet planes do carry a starter with them (in the tail usually) so the fact the SR-71 doesn&#x27;t suggests the tradeoffs wasn&#x27;t worth it

      Granted there are likely many obstacles to getting this airframe flying again, but the V8s probably isn&#x27;t one of them. All those V8s did (and I&#x27;ve seen them in action) was turn a shaft. There&#x27;s an infinite number of alternate options available to turn the same shaft.

        &gt; but the V8s probably isn&#x27;t one of them<p>You can credit card as many ready-to-run 9L+ V8 engines as you want[1], built to modern tolerances using high quality tooling, tested on a dyno and equipped with a warranty. Maybe different mounts and&#x2F;or couplers are needed, but that&#x27;s a very finite problem.<p>I suspect one actually difficult problem would be finding a refiner that can make the special fuel used in the unique engines of the SR-71. Then again, the US has a great many agile refiners at its disposal.<p>The SR-71 is a rather awkward thing to operate. Fuel leaks out of the tanks until atmospheric friction heats the aircraft enough to make them seal. It&#x27;s a big mess, and the cohort of people that were actually capable of making these things work is aged out of the workforce.

      What&#x27;s so surprising is that this is supposedly using an SR-71 that was on outdoor display. The Museum of Flight in Seattle has one in much better condition.[1] It&#x27;s on loan from the USAF, so the USAF could take it back if they needed it. There&#x27;s another one at the US Air Force Museum in Dayton, and a third at the Smithsonian&#x27;s annex in Chantilly, VA. All three of those have been stored indoors in good conditions, and were flown to their current location under their own power. Not abandoned outdoors on a pylon.<p>This sounds too much like a politically motivated decision.<p>If the US needed a hard to shoot down recon aircraft, converting a cruise missile to carry a recon package would probably be quicker. There&#x27;s also the X-37B, the unmanned mini space shuttle the USAF has. The USAF launches one once in a while. It stays up for a year or so, and then comes back down and lands. There have been about eight flights. Seems to work fine. Once it was put into an orbit that grazed the atmosphere and went back out, to test if could do high-altitude recon if desired. It looks a lot like the original Space Shuttle, but it&#x27;s much smaller, about the size of a small aircraft.<p>[1] <a href="https:&#x2F;&#x2F;www.museumofflight.org&#x2F;Exhibits-and-Events&#x2F;Exhibits&#x2F;blackbird" rel="nofollow">https:&#x2F;&#x2F;www.museumofflight.org&#x2F;Exhibits-and-Events&#x2F;Exhibits&#x2F;...</a>

    • somenameforme14 hours ago
      There was something special about the 60s in the US. Your comment implies you might not appreciate how absurd the SR-71 was. The F-35 is our latest fighter jet. It has a top speed of 1200 mph, the SR-71 had a top speed of 2200 mph. The F-35 is capable of operating at around 50,000 ft, the SR-71 was capable of operating at 85,000 ft. The F-35 has a self fueled range of about 1350 miles, the SR-71 had a self fueled range of 2,900 miles.<p>Look up aviation records and you&#x27;ll find the SR-71. It even still holds the #1 spot for the fastest airflight (by a plane) ever. Basically, the SR-71 is old, but old doesn&#x27;t mean antiquated. The 60s was the era that we went from knowing basically nothing about space, to putting a man on the Moon in 7 years (Kennedy gave his &#x27;to the Moon&#x27; speech in 1962, first landing 1969), while we currently flail about trying to recreate it with a program lasting into the decades already. The SR-71 was another product of this era.

        • somenameforme10 hours ago
          Why not? Losing that level of capability, and the ability to iterate upon it, seems like terribly poor strategic planning in the past - much in the same way that ending human space after landing on the Moon was also quite poor strategic planning. Reviving the SR-71, in much the same way that human spaceflight is also being revived, seems quite logical - especially because in the case of the SR-71, in contrast to rocketry, there is nothing remotely comparable in the commercial domain.<p>Near the top of this thread, there&#x27;s a lot of debate and discussion about what we must have &#x27;secretly&#x27; concocted. Some think that the various sighted UFO&#x2F;UAVs might be secret US tech. But I see no reason to think this is the case, in no small part because things like the decision to retire the SR-71. You don&#x27;t get from A to E without going from B C and D.<p>There&#x27;s also other practical reasons. If we did have anything meaningfully advanced then it&#x27;d be being used, however grossly inappropriate it might be, in places like Iran. No chance the current administration holds anything back for the sake of some strategic edge in a possible future conflict. I also think secrecy in modern times is not especially realistic. Everybody has eyes in the sky, to say nothing of probable increases in human level spying and the like. And so forth. Basically the idea of rebooting the SR-71 would be precisely with the aim of <i>eventually</i> fulfilling these sort of &#x27;fantasies.&#x27;

          There were armed variants like the YF-12. So far as I understand, the main reason the game changed is because missiles improved.

In that context you simply have to pray your counter-measures work, and if that fails, then hope your ejection seat works.

    About two thirds through the article, I&#x27;m getting an utter sense of dread:<p>I seriously hope they didn&#x27;t dump all available information into an LLM and are now hoping&#x2F;assuming they can use that to reengineer &amp; rebuild the necessary physical tools to get it flying again.

    SR-71 stories will always get my upvote! I don&#x27;t care if my comment gets downvoted but this is my favourite plane and especially the stories that go with it.

    The Speed Check story (for today&#x27;s lucky ten thousand [0] who don&#x27;t know):<p>Video<p><pre><code> https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=wigZsFypdyI&amp;t=3355s (around 6min, starting from around 56min) </code></pre> or Text [1]<p><pre><code> There were a lot of things we couldn&#x27;t do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment. It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet. I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn&#x27;t match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury. Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace. We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: &quot;November Charlie 175, I&#x27;m showing you at ninety knots on the ground.&quot; Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the &quot; Houston Center voice.&quot; I have always felt that after years of seeing documentaries on this country&#x27;s space program and listening to the calm and distinct voice of the Houston controllers, that all other controllers since then wanted to sound like that, and that they basically did. And it didn&#x27;t matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios. Just moments after the Cessna&#x27;s inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed. &quot;I have you at one hundred and twenty-five knots of ground speed.&quot; Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. &quot;Center, Dusty 52 ground speed check&quot;. Before Center could reply, I&#x27;m thinking to myself, hey, Dusty 52 has a ground speed indicator in that million-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol&#x27; Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He&#x27;s the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet. And the reply, always with that same, calm, voice, with more distinct alliteration than emotion: &quot;Dusty 52, Center, we have you at 620 on the ground.&quot; And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done - in mere seconds we&#x27;ll be out of the sector and the opportunity will be lost. That Hornet must die, and die now. I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn. Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet. Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke: &quot;Los Angeles Center, Aspen 20, can you give us a ground speed check?&quot; There was no hesitation, and the replay came as if was an everyday request. &quot;Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground.&quot; I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice: &quot;Ah, Center, much thanks, we&#x27;re showing closer to nineteen hundred on the money.&quot; For a moment Walter was a god. And we finally heard a little crack in the armor of the Houston Center voice, when L.A.came back with, &quot;Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one.&quot; It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day&#x27;s work. We never heard another transmission on that frequency all the way to the coast. For just one day, it truly was fun being the fastest guys out there.

    This super secret plan was &quot;leaked&quot; at the All-In summit run by a group of billionaires who grifted Trump&#x27;s victory by lying to their audience and appearing on Russia&#x2F;MAGA channels like The Duran.<p>Announced by another billionaire Isaacman.<p>All this means is that the SR71 looks cool and is thus suitable as a carrot before the midterm elections. A false carrot just like the lies about isolationism the &quot;the besties&quot; peddled up to 2025.<p>The all-in podcast should be a study object for the most effective propaganda in history.

      I wouldn’t mind, as long as the plane flies again.<p>It’s a true marvel of engineering.
      • tclancy15 hours ago
        Not a trick to make an old plane fly again. The trick is holding it together and landing it.<p>I would imagine the problem they have with the 70 year olds they’re trying to recruit is that there are old pilots and bold pilots but well, you know the rest.
        • rbanffy8 hours ago
          OTOH, a pilot in their 70’s can be bold and still die of old age.

    The new planes (F-35) were supposed to supersede interceptors like the SR-71 (that&#x27;s their multirole goal). If it can&#x27;t, this is an embarrassment.
    • flkiwi15 hours ago
      What? The SR-71 was a strategic reconnaissance aircraft. It was not, and never was, an interceptor. And the F-35 was never tasked with replacing an interceptor, but is a slow-ish multirole aircraft with a heavy emphasis on strike capability. And the USAF hasn&#x27;t had an &quot;interceptor&quot; in decades (single mission, short range, high speed, point defense aircraft).
      • AnimalMuppet15 hours ago
        There was a YF-12 interceptor prototype that was a variant of the SR-71 prototype (A-12).
      • gaigalas14 hours ago
        Makes sense, the SR-71 has never intersected with any interceptor program. And the F-35 is perfect for its role (whatever it is) which is very much relevant for the current theaters. There is no embarrassment whatsoever.
