Val Kraut - 29 Sep 2007 02:05 GMT Before you criticize try to understand the world situation today. There are many things we did years ago that are still beyond the state of the art in some unfriendly nations out there, and we shouldn't be giving them a free hand up. When Chinese launchers were used to place Iridium satellites in orbit they needed help in orbital transfer techniques for launching multiple satellites on one booster. The Clinton administration handed this away - something we developed during Geminin days to support the Apollo missions. Then a little bit later they use these techniques in destroying an obsolete communications satellite - a capability that would allow them to destroy our satellite systems during a wartime situation. The Iranians are still trying to get hardware and information to get their F-14s operational. Just cause ours have been scrapped doesn't make theirs any less lethal. Technology transfer over seas is a major and complicated issue, and the constraints are not always obvious. Stealing American technology is a major goal of foreign nations - one for military purposes and two to hand off to their companies that are in competition with ours. Some of the later involves countries we usually consider to be friends.

If the US government feels that certain information should not be released because it could be used by a foreign power in a way that was militarily significant, then it should enact a ground for the purpose, if the legislature will let it, not bend another ground beyond breaking point.

Val Kraut - 29 Sep 2007 02:41 GMT Almost anything that has to do with space vehicles has some military potential, we are also in the beginnings of a new space race where our tax payer dollars shouldn't go to helping the other guy. It seems to me we tend to split hairs on legal nuances instead of just taking the practical view - our tax payers paid the bill, our technologists developed it and it's urs - period.
The Freedom of Information Act was created to keep our government from hiding things from the American public that they really had a right to know, not for aiding foreign countries in their technological goals.

Certainly preventing the government from keeping secret things that were merely embarrassing to the government was a goal, but once you talk about things that the public have a "right" to know, it simply begs the question of how far that right extends.
Freedom of Information Acts around the world have been created in a environment where the default behaviour of executive government was to keep things secret. In that context, they should be seen as creating a right to know everything except those things for which there was a compelling need for secrecy. To the extent that the legislature considers the right not to be that wide, it can say so. Until it does, the executive should implement the law as it's written, not as they'd like it to be written.

Like doing a "Grand Tour" mission to the outer planets for example. Unfortunately the planets aren't going to line up that way for a century or two to allow someone to try that again via gravity assist, and by then even Tahiti is going have the ability to do it. I assume the big problem is the RTGs on Voyager. Unfortunately, the Soviets used those on their remote weather sensing stations along their polar shores, but between the time USSR fell and modern Russia emerged a few years later... and they got around to checking up on them again...most of those RTGs had mysteriously vanished somehow.

One thing you will find out by studying the history of espionage over the past 200 years is that everyone was infiltrated by everyone else to a degree that they never even suspected in their most horrible nightmares - to the point where the US could decode Japanese diplomatic intercepts pre-WW II faster than their own diplomats could, and the Soviets were hard pressed to get the stuff they received from their 1940's-1950's spies in the US atomic weapons program translated into Russian at the rate they were receiving it on a day-to-day basis. There were two brilliant ideas for countering this; the first was used by Kelly Johnson of the Lockheed "Skunk Works" when the they were designing the F-117: A.) There are around fifty people involved in this whole program who actually know why the F-117 looks like that...by the time it got to the production floor, the people who actually built it knew exactly how to make those particular angles on it to those particular tolerances, but had no idea why that was important, because we burned all the papers concerning that before we put into production. Or: B.) The B-2 generated around 10,000 pages of paperwork per day from the start of the program, and topped out at around 100,000 pages per day when it hit full speed...which means if none of that paperwork was classified "Top Secret", anyone trying to figure on what we were up to would have been like someone looking for a diamond in a coal deposit, because around 99.99% of it was completely worthless from espionage purposes, and they'd never know what was important or not. Luckily, we were smart enough to mark select parts of it "Top Secret" so that Soviet spies would know where to find the good stuff. This was highly successful in keeping the aircraft's design concepts secret, as they had a pretty much identical design ready to go by the time ours entered service, except that their intake and exhaust design looked smoother than ours. :-D

It was all secret, at least to the extent that we weren't meant to talk about it.
Yet many of us felt that the best thing we could do to advance the security of the UK would be just to hand over the entire source code to the Ruskis. The reasoning was that it was such a dog's breakfast that they'd waste a huge amount of skilled technical resource trying to understand how it worked (which it largely didn't).

You've got to understand the Russian mindset... AW&ST: "Rumors hint at new US superweapon." Time: "Rumors of new US superweapon exaggerated." AW&ST: "New superweapon uses antimatter as key component." Newsweek: "Time magazine in error; new superweapon is impossible." Classified report to Soviet Politburo: "America develops new superweapon. Uses antimatter as key component; official denial in state-controlled American media proves its existence." :-D

(Of course, proving they're such an open society that they share their secret military research with us... and encouraging superstitious belief in the West... also has a plus side.)

But it seems to me the term "state of the art" refers more to technology infrastructure than simple vehicle drawings.
Many times the services, especially the Army, owns the drawings to weapons systems it buys. Then, it can give them to another company when the system comes up for replacement orders, and someone can underbid the original developer. But that frequently brings up problems. Even with US companies, there are lots of processes that are not included in "drawings", and the new company finds it very hard to really produce weapons at cheaper prices, because they have to develop the processes within their own company now. And, frequently the first lots from the new manufacturer have a LOT of qc bugs.
I think the same thing is true between companies. The real secrets are not in the outlines of parts on the drawings. Most countries have machine shops and machinists who can make parts to prints. Yeah, they could make a Cessna 172 with factory drawings. But items that require fancy metallurgy, composite parts, chem milling, fancy electronics, etc. are likely not to be easily produced.
Selling plans to a weapons system is not the problem- selling the process technology is what is the problem.

I saw a video recently of someone claiming that they could run their welder on water. You see, they use electrolysis to convert their H2O water into HHO water, which, when burned in the torch, produced simple water as exhaust.
Nowhere did they actually explain the difference between "H2O" and "HHO" water. They also didn't actually say they produced more energy than they used, but between the reporter's excitement and the careful statements of the promoter, you would certainly get that impression. 'Free energy from ordinary water!'

I like this Bussard widget, which is supposed to be a super-effecnt Tokamak fusion reactor design: http://www.centauri-dreams.org/wp-content/uploads/2007/01/bussard_fusion.jpg They had something just like that in John W. Campbell's "Islands Of Space" from 1931, with solid electricity stored inside of it. I assume it's made out of Relux, given its shiny silver exterior. Me, I want my polywater, and I want it now! Think of all the expense and time saved over making Jell-O by boiling water, adding Jell-O powder, and then chilling it...if you could just stir it up by adding the Jell-O powder to cold polywater. Okay, it would look like snot, but it would taste the same (as Jell-O, not snot). :-)

It is more closely related to the electrostatic confinement fusion devices originally patented by Philo Farnsworth (whose enduring invention is the electronic television tube) in the 1960s.
Dr. Bussard passed away earlier this month, but I believe that the project has recieved funding to continue research and development from the US Navy.

[Last use was USN VO-67 in the late '60s and early '70s.]
:Despite it's alleged accuracy ("Bombs in a pickle barrel from 30,000 :feet!") cross winds as the bomb fell meant they were lucky to land :within a thousand feet of the aim point. You exaggerate in the other direction. The Norden was generally spec'ed to put bombs from 20,000 feet into a 100 foot circle. Operationally it was somewhat worse than that, but "lucky to land within a thousand feet of the aimpoint" is simply wrong. It did much worse in the Pacific Theater than in Europe due to bombing from 30,000 feet (vice the 20,000 feet it was designed and tested at) and because of jet stream effects.
Hint: The Norden had inputs for crosswind effects.

There was an international conference on nuclear power- I think it may have been specifically on fusion. It was hosted somewhere in this country-forget where. A Russian physicist was invited to give a paper on his work on laser containment fusion. The DoD objected- that topic was classified- and went around collecting pre-prints the guy had sent out.
Now, being both ex-military and a retired aerospace R&D engineer, I certainly understand the need for secrecy in some cases. The problem is that the service security agencies have no real idea of the reason for such security and end up classifying the WRONG THINGS! They are trained in document security, spying, and such, but NOT on WHAT needs to be classified and why.
Supposedly in the R&D arena it was up to the scientists and engineers to define what would be classified, but there were customer (military services) guidelines, and they frequently made no sense. They had no idea what parts of a new technology should be classified and what shouldn't.
The biggest reason for military security is to not allow your opponents to draw up a clear line of battle classification and know the effectiveness and numbers of your weapons systems. How to build them is NOT the big thing. Most halfway developed countries can develop them themselves. It is knowing what we are ready to deply, its effectiveness, and our numbers of them, that is the real thing we need to conceal.
We need to keep secret the speeds, max altitude, range, payload, of our latest fighters, not how to build them.
Fred J. McCall - 29 Sep 2007 16:55 GMT :Supposedly in the R&D arena it was up to the scientists and engineers :to define what would be classified, What country was that in?

:... but there were customer (military :services) guidelines, and they frequently made no sense. They had no :idea what parts of a new technology should be classified and what :shouldn't. Again, not how it works. Folks with original classification authority produce a Classification Guide, but it's not 'guidelines'. It mandates what is and is not classified. Every case where it is "up to the scientists and engineers to define what would be classified" is a case of what is called 'derivative classification' and traces back to that program classification guide.
See Executive Order 12958 (April 17, 1995) for latest guidance on this subject.

And they sell to people who are not nice, so if they really do refrain from exporting some nasty stuff at all (and aren't just making it up) that would be good too.
Also, the U.S. is believed to have the top technology in the world; only people living in poor countries are deprived if they can't even get ahold of Chinese technology; all the rich countries ought to be able to do at least as well as China.

I speculated it may have been because of its large, deployable antenna. But after talking to a friend who used to work at Harris (they made the thing), it still seems silly. The easy part about making such an antenna is deciding what shape it needs when deployed. The hard part is getting a structure designed so that it will deploy and (eventually) settle down to its final shape, which has to be very accurate and precise.
The guys I know who used to work at Harris are still upset at what JPL did to their antenna.

Okay, so maybe it got a little bent or something when they were looking at it....but they won't ever do that again, they promise. :-P

They obliged with no objections. I have it to this day and treasure it. Full size mechanical layout, orthographic, without insulation blankets.
