original plan was smaller, but military had a mission in mind that required it be bigger, so they went bigger to get military buy in. And of course the imagined mission never happened. I wonder how much money would have been saved!

There were 11 classified (ten successful) DoD space shuttle missions:

https://www.space.com/34522-secret-shuttle-missions.html

That's roughly 8% of shuttle missions.

The mission I believe the parent comment was referring to was a foreign (Soviet) satellite recovery. It required a larger payload bay and as I recall a very aggressive launch profile that I believe also imposed some undesirable design constraints, but my memory is fuzzy.
Re:James Webb telescope reaches its final destination in spa... by bewaretheirs on Tuesday January 25, 2022 @03:05PM (#30077272)
My understanding was that the specific requirement was for a launch into polar orbit (southbound from Vandenberg AFB, just north of Los Angeles) and then a landing ~90 minutes later at Vandenberg, clearly to snatch something out of orbit.

Since the earth is rotating under the orbital plane of the shuttle, this requires a large amount of cross-range maneuverability on reentry so it could land back in California rather than ~22.5 degrees west of Vandenberg in the pacific ocean, and this required large wings.

I don't believe it's known for certain outside of classified circles what was to be brought back. One theory was that it was to snatch a Soviet spy satellite out of orbit, but it's entirely possible given the timelines that the classified requirement was to pull a film cartridge from a US spy satellite in polar orbit and return it quickly to earth for processing.

Unfortunately there would be no way for the USSR to know that they weren't going there to nuke Moscow from the south where there weren't any radars looking. I'm not sure if that was ever seriously considered on the US side but my sense is that the eventual realization that there was no way for the USSR to know and trust that is part of what stopped the shuttle from ever launching from there.

Given that many details of the keyhole program were recently declassified [1], is there any chance we'll get to know the true nature of the shuttle program? (And if so, when might it happen?)

The shuttle had plenty of military missions, and most are still classified.

No, we never got the Vandenberg polar launches we were promised.

And I don't think anyone anticipated just how quickly miniaturization and automation were going to advance when it was designed in the 70's or even as missions began in the 80's.

Even autopilot was a controversial cutting edge technology that was excluded because of the focus on human centered missions.

But back to military- it's not a coincidence that Hubble fit so perfectly in the shuttle cargo bay.

(Hubble being a spare keyhole spy satellite body, with borrowed mirror fab tech.)

But it would be interesting to know just what else the military had in mind, besides their not-so-secret ambitions for militarized manned space stations.

I assume Hubble was built that size because it would fit? No coincidence indeed. And what does that have to do with the military?

Not exactly, I think they just use a specific mirror design (2.4m dia.) because they are already manufacturing them to be used in spy satellites.

This is the case with almost all large scale human endeavors. To get things done with lots of people takes compromises. Apollo program was the same way. I assume the pyramids and roman roads and so on as well. Though to be fair at some point once the shuttle program got going someone could have aborted on it and said that really this doesn't make sense.

That's what army mapping service essentially did with early radar distance measuring projects. Huge expensive fleet of 18-wheeler trucks failure. And classical surveying methods beat it in every way at the time.

But it was the direct predecessor to microwave communications. It was just portable military distance measuring equipment (like the model-99 dme w/ ~1cm @50km) that used a signal they found easy to piggyback voice and data on. And included that in the field units.

AND 2nd, after a dozen or so more hugely expensive projects (ranging from failure to moderate success to "achieves objectives"), it led to the Airforce NAVSTAR program, which you know as... GPS.

So the question becomes: What was the actual "objective" value provided by those expensive initial radar experiments, despite failing to achieve their direct objective?

Re:James Webb telescope reaches its final destination in spa... by whatshisface on Tuesday January 25, 2022 @11:46PM (#30081834)
It's difficult to say without access to the counterfactual world where GPS was invented based on civilian microwave communication which itself would have evolved from civilian radio communication. We live in a world where the DoD redistributes money away from private industry and towards another sector of private industry, and it is hard to say what would happen if R&D tax laws were changed to move that money back from private military industry R&D to industry-industry R&D.
Re:James Webb telescope reaches its final destination in spa... by beerandt on Friday January 28, 2022 @11:33AM (#30116892)
Maybe microwave transmission, but the economics of GPS or GNSS in general would preclude civilian investment in such an expensive constellation without obvious revenue channels.

And it's moot for both these cases because the technology was needed for direct military applications anyway.

What's the practical or ideological benefit of industry-industry R&D when the military is going to be the only customer, or at least the only paying customer for the first years/decades of use?

I agree with you in general, with it being better for governments not picking the winners of markets or deciding who gets research money.

But military is such a unique (yet universally needed) type of market, that practicality here means treating them as a large customer with unique product needs ( products unlikely to be revenue generating on the public market), even if you don't treat it as direct government allocation or a fixed/manipulated market.

The only way I can think of to avoid that entirely would be some libertarian version of an all private, defense-by-contract type military.

And then you'd have concerns about whether that could hold up to peer adversaries, and dozens of other wildcard concerns.

That's the stereotype of government promoted by private business like SpaceX, so they can get the funding shifted from NASA to them.

OTOH, they also influenced it in many good ways that you don't hear about.

E.g., my astronomy professor mentioned to me in a conversation that the original design for the Hubble was smaller due to expected budget, but that it got up-sized because it turned out that they could piggy-back off of other relevant military development, and iirc, that went beyond just the larger available size of the shuttle bay.

Re:James Webb telescope reaches its final destination in spa... by simonh on Tuesday January 25, 2022 @10:23AM (#30072775)
The mission being referred to was capturing a Russian satellite in a polar orbit in the cargo bay and returning it to earth. The shuttle also needed big wings to provide the cross-range capability it would need to complete one polar orbit and land at the original launch point (Vandenberg) despite the earth having rotated, moving the airbase by many hundreds of miles since takeoff.

The original NASA spec had a smaller cargo bay and wings because it would have mainly been a crew ferry. As a result it would also have been launchable on top of a rocket instead of strapped to the side, giving better safety. Significant cargoes would have been launched independently.

Re:James Webb telescope reaches its final destination in spa... by barkingcat on Tuesday January 25, 2022 @02:05PM (#30076429)
re military mission never using the size, there could always have been classified payload launches that ended up using it.
Re:James Webb telescope reaches its final destination in spa... by beerandt on Tuesday January 25, 2022 @07:55PM (#30080295)
There were plenty, the military missions existence and classified nature weren't classified themselves. (Or at least plenty enough weren't. We wouldn't necessarily know of ones that were.)

So the "classified DOD project xyz" tasks are listed right there on the published official mission lists and schedules, and quite easy to look up on both Wikipedia and straight from NASA.

But the thing not achieved was Vandenberg launches, which would allow more N-S polar orbits that are often more useful to the military.

The less official but still obvious thing not achieved was the Airforce building a manned military space station (as far as we know...).

I've heard the (probably unfounded) story that the Soviets saw the Space Shuttle, couldn't figure out why the Americans would build it but figured there surely must be a good reason; so they copied it to also have whatever capability the Americans were after.
Re:James Webb telescope reaches its final destination in spa... by cronix on Tuesday January 25, 2022 @12:34PM (#30074864)
It's not unfounded, and they knew about it before it ever flew once. A family member was in the CIA at the time (later at NSA and RAND) and played a role after they were sent to the USSR after graduating college to study Russian (paid for by CIA, they know 8 languages). They translated the technical Russian Buran plans/documents and decoded them for our scientists to compare to their own, as well as help slip design flaws into plans they knew would get stolen (because they knew who was stealing them from Nasa). They met with the president over the issue multiple times. True story. They were also involved in every stealth program until they retired in the early 2k's. They were in the pentagon when the plane struck on 9/11. I really wish I could get them to talk more or write a book lol. [Using "they" to avoid gendering family member]

The Soviets (at the time) didn't "copy" it. They stole the plans and made it from them, adding in a few alterations, although the plans they stole were purposefully flawed.

If you're up for it, you can visit the Buran's in their final resting place in Baikonur. They're just sitting there rotting away. Here's a video of some kids who broke in and had some fun exploring: https://www.youtube.com/watch?v=-q7ZVXOU3kM

Buran was also superior in capabilities; greater lift capacity, ability to transport more people, and attain higher orbits. It could also perform a mission entirely autonomously.

The US Space Shuttle was the (heavy) inspiration, but the Soviets put their own spin on it.

Five Shuttles flew to space - Columbia, Challenger, Discovery, Atlantis, Endeavour. And Buran - the one which flew (other Soviet spaceplanes would have different names, so Buran is like Columbia, not like Space Shuttle) - didn't have e.g. the life support system; it was rather a development flight, than a demonstration of a complete system. Still Buran (as a combined name, like Energiya-Buran program) had some better capabilities e.g. no toxic propellants onboard (Shuttle has to be chemically "pacified" after each landing) and longer orbital life (with cryogenics onboard).

Re:James Webb telescope reaches its final destination in spa... by enave3 on Tuesday January 25, 2022 @10:51AM (#30073157)
> What was the intended mission?

There were several. A couple of examples: the shuttle could delay release of a payload, maneuver while in orbit, release the payload, then maneuver again. So conceptually, you just put a satellite into an orbit and your enemy doesn't know exactly what orbit its in. I'm sure eventually they would find it, but the military still wants stuff like that.

Another example is the ability to grab a satellite and bring it back to Earth. To my knowledge, this was only ever used with the "long-duration exposure facility" because it'd probably be considered an act of war to steal another country's satellites but here again, it's the kind of thing the military would ask for.

Re:James Webb telescope reaches its final destination in spa... by kzrdude on Tuesday January 25, 2022 @02:38PM (#30076895)
Isn't the shuttle so big that it would be easy to track and see it?
Re:James Webb telescope reaches its final destination in spa... by enave3 on Wednesday January 26, 2022 @02:09PM (#30090231)
yes, but no country can track a given object in LEO for its entire orbit (unless it's transmitting its position to another satellite).

So the idea is that the shuttle launches with a secret payload, and every 90 minutes you see it pass overhead. This goes on for days or weeks. Eventually it lands.

What happened? Well what you don't know is that on day 2, while it was over the Pacific and you weren't tracking it, it fired the OMS, deployed a payload, then fired the OMS again to return to it's previous orbit.

There's a whole other satellite out there and you don't know about it until you find it by some other means. And eventually you will find it. But the military is happy to pay for that short window of subterfuge.

Re:James Webb telescope reaches its final destination in spa... by messe on Tuesday January 25, 2022 @11:50AM (#30074141)
The one that had the biggest influence on the design of the shuttle was probably the plan to launch into a polar orbit, rendezvous with a satellite, capture it, and land as it swung around for the next orbit. This require massive cross-range capability, in order to be able to glide back to a suitable landing site in the US, putting lower limits on the size of the wings.
