For aerospace aficionados, it’s like we have entered into an alternate dream reality. The idea that we are seriously talking about the possibility of bringing back the SR-71 Blackbird to flight status is hard to comprehend, but amazingly this is where we are at. The biggest question I am getting about all this is why? We touched on the likely primary answer to that in our original reporting — high-speed is back in tactical vogue, and the Blackbird can sustain it in a realm of great interest, between Mach 3 and 4, and do it over and over again. It can also carry very large things and even launch them off its back at those extreme speeds. But those are not the only potential reasons for taking on such a gargantuan, high-profile, and costly technical challenge. Learning from the journey itself could be just as valuable as the actual flight test data a revived SR-71 produces.

Let me explain.

The Blackbird was as close to alien tech as it gets over 60 years ago, and even today, we have nothing like it in known operation. Yet it has been dormant for nearly three decades. Much of the expertise that built, supported, and operated it is sadly gone. But the exercises of reverse engineering and leveraging breakthroughs in additive manufacturing and rapid prototyping, as well as injecting new material sciences, avionics, propulsion and other technologies where applicable, and above all else, building the digital toolkit to make it all happen as fast and efficiently as it can be done, are all of extreme learning value.

I would not be surprised if a ‘digital twin’ is being created right now of the SR-71 using NASA’s SR-71 tail number 844 — the jet in question that has mysteriously disappeared from its display pad. Once such a model exists, breakthroughs in digital engineering can be brought to bear to see how fast the program can be accelerated, both in terms of development and flight testing. This could include not only getting the SR-71 back in the air, but improving its performance and reliability, possibly substantially, using all the new technologies we have today. It’s even possible a clone of sorts leveraging all these advances could be built using digital engineering tools.

This is not necessarily an unprecedented concept. Just look at similar exploratory engineering programs like the X-55. But when it comes to partially reverse-engineering an airframe you have no support for, and few, if any, spare parts, America’s highly-secretive foreign materiel exploitation (FME) community could potentially lend a hand.

Operating in the shadows, they have been able to not only get totally foreign aircraft divorced from American supply chains pieced back together and flying, but they sustained them for years in total secrecy. They also did this long before the advent of rapid prototyping and digital engineering assets that we have today. Imagine what they can do now. They could be a top source for NASA to pull in to help in its far less sensitive but uniquely similar endeavor. This is just one example of many of how government and industry could come together to support and benefit from the SR-71 resurrection program.

Now, about those supply chains. During its heyday, the SR-71’s logistical tail was one of the most exotic ever created. It supported the Blackbird, as well as its progenitor, the A-12, for the better part of half a century. Reestablishing this supply chain would be a highly challenging, but rewarding exercise that could have major impacts across the aerospace industry, as well as others. So, how can we use all the capabilities we have now to jump-start the sustainment of the highest-performing air vehicle from an era of slide rules and drafting tables?

The idea of putting aircraft out of production back into production is not a foreign one to the U.S. military, either. NASA’s SR-71 program could serve as a pathfinder for better evaluating such proposals and their costs, while pushing the envelope forward on exactly how it can be done efficiently. The same can be said for simply keeping aging aircraft (or any vehicle or system for that matter) operating longer and for cheaper, by applying cutting-edge technologies and practices. NASA can create the playbook for doing so, and that playbook could end up being more valuable than the flight testing a reborn SR-71 does.

I think it’s fairly clear that we have lost something when it comes to aerospace engineering as of late. With all our advances and incredible tools even legendary Skunk Works founder Kelly Johnson could have only dreamed of, it seems like we have to relearn even simple lessons from decades ago, and oftentimes that can be a very expensive, time consuming, and even deadly process. In some ways, it seems like we have gone backward, or at least stalled out in certain engineering areas. The simple things become hard and hard things have become simpler. How did they do so much protractors and pencils way back then? Getting a Blackbird flying again can help explore and possibly answer this and other questions, and help mitigate these deficiencies going forward, as well.

Even if NASA’s dormant SR-71 never ends up getting back in the air, even attempting such a challenge could be considered a success. Doing so could identify core areas across multiple disciplines that could be improved and areas of existing technology that could be better exploited for a whole array of tasks. It can also develop and refine new technologies in the process. All this sits at the core of NASA’s mission, and there is no vehicle on Earth that could drive people and organizations to give it their all for such a comeback dream as the Blackbird. It’s even possible that we could see corporations or even individuals help foot the bill for it.

And yes, all these benefits need to be weighed against cost. Surely there is a limit to how much the government can invest in such a program. Now corporations and individuals, that’s a different story.

So, yes, the main goal of this effort will likely be high-speed flight testing, but so much can be learned in the journey to get there that it must be quantified in the ‘business case’ for reviving the Blackbird.

The post Lessons Learned From Getting An SR-71 In The Air Again May Be As Valuable As Its Flight Test Data appeared first on TWZ.

NASA Administrator Jared Isaacman has left something of a mystery hanging in the air after showing the silhouette of an aircraft that immediately drew comparisons to the famed SR-71 Blackbird during a recent speech. Isaacman pushed back on a direct link to the SR-71, but said his agency is working hard to get “back in the business of flying high and fast again.”

The silhouette, accompanied by the tagline “Rebuilding our X-plane portfolio,” was among the backdrops for Isaacman’s remarks at the annual All-In Summit in Los Angeles, California, last week.

The SR-71’s iconic shape is defined by its long, sword-like profile, pronounced chines, and deeply swept wings, and huge spiked engine nacelles with canted fins on top. Its distinctive geometry is reflected in the silhouette, which shows a broad, highly blended aircraft from an unusual head-on angle.

“In the service of the first A [aeronautics] in NASA, we are rebuilding our X-plane fleet. The X-59 is researching quiet supersonic flight, but it’s just the beginning,” the head of NASA told attendees. “As NASA recommits to flight test and works alongside industry to push the boundaries of airframe and propulsion design, it will not be long before NASA once again is flying as high and as fast as we had in decades past, and then even more.”

Isaacman’s full speech at the All-In Summit, as well as his remarks during a live interview that followed immediately afterward, are contained in the video below. The high-speed aircraft silhouette is first seen at around the 12:40-mark in the runtime, and is then further discussed at around the 28:39-mark.

Chamath Palihapitiya, co-host of the All-In Podcast and one of the hosts of the summit, asked Isaacman directly about the silhouette during the fireside chat after his speech.

“You showed a picture of the [SR-71] Blackbird up there,” Palihapitiya said at one point, before Isaacman interjected.

“You sure that’s a Blackbird?” Isaacman said.

“Well, ok. What was that picture you showed up there?” Palihapitiya asked.

“Like I said, NASA is getting back in the business of flying high and fast again,” Isaacman said in response, and declined to further elaborate.

Whether or not the silhouette reflects a real design that is in development now is unclear. TWZ has reached out to NASA for more information.

Though the Mach-3+-capable SR-71 is primarily remembered as a Cold War-era intelligence-gathering aircraft, NASA operated several Blackbirds in support of aeronautical research efforts for years. The agency was actually the last operator of the type, flying SR-71s until 1999.

Lockheed Martin openly pitched a successor to the SR-71, dubbed the SR-72, in the late 2010s. There was even talk of building a flying fighter jet-sized demonstrator to prove out key technologies.

Discussion about the SR-72, or a further evolution of that concept, resurfaced in the early 2020s after Lockheed Martin helped craft a fictional hypersonic aircraft called Darkstar for the blockbuster movie Top Gun: Maverick.

Exactly where Lockheed’s SR-72 ambitions sit today is unclear. After talking constantly about the potential program for a number of years, it went silent, which could indicate the program had moved forward deep in classification.

NASA has worked with other supersonic and hypersonic X-planes in the past, as well. This includes reusable space planes, as well as aircraft designed to fly within the Earth’s atmosphere.

“I mean, that doesn’t seem like a space vehicle. It seems like an Earth-air vehicle,” All-In’s Palihapitiya noted during his chat with Isaacman about the silhouette he showed.

“Yeah. The first ‘A’ in NASA is our aeronautics portfolio,” Isaacman said in response, before highlighting a host of contributions his agency has made to advanced military and commercial developments over the years. “You know what I want to do? I want to get back to the radical airframe and engine designs like we were always supposed to do.”

As mentioned, Isaacman also highlighted the X-59 Quiet Supersonic Technology experimental test aircraft, or QueSST, at the summit, but made clear the goal is to go well beyond that design. The QueSST jet is the centerpiece of a program now to investigate technologies that could eventually enable commercial supersonic flight over land with a substantially reduced sonic boom.

The X-59 conducted its first supersonic test flight, reaching Mach 1.1, in June. NASA’s test program aims to eventually push the aircraft up to a speed of Mach 1.4. This is significantly below the record-breaking mark of approximately Mach 3.3 that the SR-71 clocked back in the mid-1970s, but it was never designed for extreme speed as testing its sonic signature was its primary goal.

As for bringing a Blackbird back into operation for high-speed testing, which is now at the forefront of military aeronautics (and civilian to a lesser degree) after decades of being sidelined, that would be a very challenging operation. The SR-71s are long retired and have been placed in museums and other display areas. While the Pentagon could technically claw some of them back from their ‘on loan’ status, reconstituting even one of them would be a major undertaking as the entire support ecosystem that once sustained them has been gone for decades. Still, having a Mach 3+ capable jet for testing would be a highly relevant tool in a new age of high-speed flight exploration.

On the other hand, building a new test aircraft that aims higher and faster than the SR-71, but may be based on its ‘DNA,’ is certainly possible. Such an aircraft could leverage material science, avionics, flight controls, and engines that are seven decades more modern than its progenitor. Technology demonstrators in this class could also already exist in the classified domain. NASA could possibly assume ownership of one after the Pentagon declassifies it, as well.

Regardless of how such an exotic aircraft is obtained, one of the biggest differentiating factors could be that a NASA aircraft is piloted by a human onboard, instead of it being a drone, but an uncrewed aircraft is possible too.

Isaacman has been very open about its interest in and support for new X-plane developments. On only his second day on the job, in December of last year, he called for revamping the agency’s aeronautics program and stated that “I’d love to see an expanded X-plane portfolio” during a town hall with NASA staff.

“If NASA has a healthy X-plane portfolio, we should be flying experimental aircraft so routinely that the second flight of a single X-plane is not newsworthy,” he wrote in a post on X in March of this year. “For example, the two NASA X-29 aircraft flew 422 flights between 1984 and 1991. That period also overlapped with the development of two X-31 aircraft, which together flew about 580 times.”

NASA’s proposed FY2027 budget also spelled out rapid, cost-effective flight experimentation as an explicit priority. Budget documents specifically highlight work toward new advances in supersonic and hypersonic flight technologies “that will revolutionize air transportation, strengthen national security capabilities, and position America to lead the future of high-speed flight,” as well.

Furthermore, in April, NASA outlined a new Aeronautics Flight Accelerator (AFA) initiative. At that time, the agency put out a call for “input on technologies, concepts, and flight test campaigns suitable for cost shared maturation leading to flight within the next three years.” Stated areas of interest included “subsonic (including vertical lift), supersonic, and hypersonic flight technologies.”

It is important to reiterate that we still do not know whether the silhouette Isaacman showed at the All-In Summit represents an active development effort and, if so, how mature it might be. Government agencies and contractors routinely use concept art to illustrate an area of research or communicate a future vision. Such artwork does not necessarily correspond to a funded aircraft, an active prototype, or even a specific configuration.

At the same time, under Isaacman, NASA is clearly pushing toward new X-planes. NASA’s X-plane programs have historically served as a way to investigate technologies that conventional aircraft programs were not prepared to risk. The resulting aircraft have explored everything from supersonic and hypersonic flight to unconventional configurations and new propulsion concepts.

At the very least, evoking the visual legacy of the SR-71 Blackbird, coupled with Isaacman’s comments, provides a clear indication that NASA is interested in returning to the high-speed flight regime as part of its future plans.

Update: 2:04 PM ET –

NASA has now provided TWZ with the following statement in response to our queries for more information:

“NASA has a long history of building and flying experimental aircraft that push the boundaries of what is possible. As Administrator Isaacman has said, we want to see more X-planes flying in the years ahead, developing the technologies that will allow us to fly higher, farther, and faster than we have in decades. We look forward to sharing more as those efforts progress.“
