This contact point can allow the electromagnetic field to enter the cage, which ultimately renders the enclosure useless. There are ways to protect against these Faraday cage flaws, but the fact remains that this is a dangerous weakpoint.
Some Western experts believe that Russia spent months preparing for the invasion, and provoked the confrontation that led to Georgia's attack on the South Ossetian capital, Tskhinvali. They pointed to military exercises the Russian military conducted just across the border in July, the lingering presence of extra Russian troops in the region in August and the speed and efficiency of Moscow's response.
The few times MIG-31's came close to the SR-71, skirting Russian Airspace, it was flying at lower speeds and lower altitudes than it is capable of cruising. Odds are that they were just trying to see what the MIG capabiliies were

Neither of us knows whether or not SR-71's flew missions into Russian air space, and if we did, we certainly wouldn't say, neither would the US or Russia openly admit such missions did take place. Most likely they did.
The SR-71 was retired in what, 1992, and still was in use until 1998. Doesn't look like it was as vulnerable as you claim. Chances are that its mach 6 predessesor flys missions where ever it chooses to this day.

By the way, even the web site, about Cuban technology, is DEVELOPING these weapons, they don't claim to actually have them yet.
The Sinus-6 can fire a several-gigawatt pulsed beam 200 times a second in 10-nanosecond bursts. "It has to be pulsed power because what you're after is high peak power," says Schamiloglu. "The power in the microwaves is going to depend on the electric field squared, so if you generate very large power, then the electric field is going to be big."
How big? To drive the Sinus-6's beam continuously for an entire second, you'd need to supply about 25 gigajoules"the entire output of a typical coal-fired electrical plant for 10 full seconds," Schamiloglu says. Another reason for pulsed rather than continuous power is to avoid a problem at the output end: the air around the antenna would heat to a plasma that in turn would interfere with a continuous beam at these power levels.
The key to reaching gigawatts of power is dumping all the energy in one gigantic, nearly instantaneous pulse. A pressurized gas switch prevents the Tesla transformer from prematurely dumping as it builds up for the next pulse. The switch is filled with highly compressed and nonconducting nitrogen gas. When the transformer coils reach 700 kV, the nitrogen gas breaks down, and the pulse leaps through to the electron-beam diode.
"Once you've fired the switch, it conducts, it generates a pulse," says Schamiloglu. "It conducts because you've made a plasma channel out of the gas. Then you have to wait for that plasma to recombine and form a neutral gas again. A typical time scale for this thing to recombine and fizzle out and be a neutral gas again is probably on the order of milliseconds."
Among the best candidates for supplying microwaves is the backward wave oscillator; it has the advantage of being tunable (plus or minus 20 percent) and producing output in the 4-10-GHz range. To turn the kinetic energy from the Sinus-6's electron beam into high-power microwaves, the oscillator uses a rippled-wall waveguide, also called a slow-wave structure [see photo
The structure sets up standing electromagnetic waves in such a way that energy is rapidly transferred to them from the incoming beam of relativistic electrons from the Sinus-6. This growing energy initially propagates in the opposite direction of the beam's movementhence the device's nameand is then reflected forward and radiated in the form of high-power microwaves. Backward wave oscillators, by the way, are also being tested as a way to push giant sails into outer space, to detect space debris, and to clear minefields.
Being able to tune an HPM weapon comes in handy when a particular target proves invulnerable to a particular frequency. "Experience has shown that if the frequency is slightly altered, measurable effects are discerned," Schamiloglu notes. People used to believe that varying the frequency of HPMs wasn't practical, but Schamiloglu and his students proved them wrong.
Coincidence and curiosity led to their discovery. Schamiloglu first acquired the Sinus-6 from Russian researchers in the early 1990s. (The Soviet Union once boasted a sophisticated program to develop microwave weapons; after its collapse, parts of that legacy were put up for sale, to the delight of researchers like Schamiloglu.) But once the apparatus was assembled in his New Mexico lab, he couldn't get it to operate as promised, so Russian colleagues flew over to help.
"One of them took the RF structure [the rippled-wall waveguide] and started hammering on the thing," Schamiloglu recalls. When they tried it again, everything worked. "I was baffled why manhandling this RF structureramming it incould affect the power so much," says Schamiloglu. So he started a series of experiments in which he slightly displaced the backward wave oscillator by increments. With a little experimentation assisted by computer simulations, his team found that the frequency could be adjusted by changing the distance between the diode and the microwave source. The result is that the backward wave oscillator is now one of the few pulsed-power HPM sources that can be tuned.
Smaller is better
One disadvantage of this oscillator, however, is that it needs an external magnetic field to create the microwave beam, a major hurdle to making the whole system smaller. The size of the Sinus-6 and attendant equipment in Schamiloglu's basement suggests that the U.S. military is nowhere near fielding a narrowband HPM weapon. "When I first started working on high-power narrowband sources, we joked that you can do more damage dropping this equipment on someone than you can by using it," he recalls. "People know how to make microwave sources in the laboratory. The challenge is to take this and package it into an autonomous platform and have it function at the same parameter levels."

The contact point CAN allow, but not necessarily. All critical military electronics, and most commercial for that matter, protect against these cage flaws. When the equipment is built from the beginning to protect against EMF attacks, it doesn't add that much more weight, or cost, especially now days, because digital information is so compressed, it has to be highly protected to prevent noise interference.

"One of the things that happened during the last 10 yearsas the Pentagon fell in love with network-centered warfareis that we purchased a lot of very fragile digital systems off the shelf from commercial sources," Thompson notes. Such moves were taken in the name of cost and efficiency, but the resulting equipment is almost certainly more vulnerable to electromagnetic attack than the vacuum tubes and heavy metal-encased electronics of yesteryear.
"Computers become more vulnerable as the voltage at which they operate becomes smaller," says Victor Granatstein, professor of electrical engineering at the University of Maryland in College Park, who is studying the effects of microwave pulses on integrated electronics. "When our opponent was the Soviet Union, the electronics were much more robust because they weren't miniaturized. Now they have very thin oxide layers that can easily break down." Wireless networking makes matters worse. Computers and other communications devices now have antennas attached, giving an electromagnetic pulse a direct pathway to its guts.
Meanwhile, the U.S. Navy no longer requires that all its hardware be hardened against nuclear electromagnetic pulses. It deemed that maintaining those standards was too costly and slowed down the integration of new technology. The presumption was that after the Cold War, nobody would be using nuclear bombs, says the Lexington Institute's Thompson. "Whenever I ask the admirals, 'Well, what if someone did use a nuclear bomb?,' I just get this kind of blank I-don't-have-an-answer-for-that sort of look."

STOCKHOLM (AFP) - The Swedish military has bought and tested a Russian electronic bomb using high-power microwave signals to knock out the computers of jet fighters and nuclear power plants, the Swedish daily Svenska Dagbladet reported Wednesday.
"Russia is among the best in the world when it comes to manufacturing this type of electronic weapon," said Anders Kallenaas of the Swedish National Defence's Research Institute (FOA).
The high-power microwave (HPM) bomb is stored in a briefcase and emits short, high-energy pulses reaching 10 gigawatts -- equal to 10 nuclear reactors.
--
The bomb presents a threat to the Swedish military, in particular to the JAS 39 Gripen jet fighter that it is trying to export. It can also knock out the electronic systems of nuclear or electric power plants, banks, trains, or even a simple telephone switchboard.
The bomb has also been developed into a pistol which can be used to knock out a single computer or vehicle.

They pointed to military exercises the Russian military conducted just across the border in July, the lingering presence of extra Russian troops in the region in August and the speed and efficiency of Moscow's response.
Russian military officials insist, however, that they were surprised by the attack and organized their response in a matter of hours.
U.S. officials were in for a surprise. After a thorough check of the MIG-25, the Americans experts came away less than impressed. The plane was quite fast, but also unwieldy and almost completely incapable of close-quarters combat. In addition, the electronic technology of the plane was deemed to be far behind comparable U.S. aircraft. As one U.S. expert joked, "I guess it could be worse; it might have been made out of wood." The MIG-25 incident suggested that U.S. officials may have overestimated the Soviet threat in order to push for even higher American defense spending.
Arguing about whether or not EMF can be stopped is a waste of time. Every article you have posted admits EMF pulses can be stopped by proper shielding, and that is the bottom line.
As I have already stated more than once, To prevent pin hole leaks for EMF penatration, all is needed is testing, and that is how pinhole leaks are stopped
As far as claims that the tubes were used on purpose for EMF hardening, I'll take the word of the scientist who looked at the MIG-25's electronics.
The only people who know how many SR-71 missions were flown over Russia or and during what era, aren't going to make the information public, and all claims otherwise are not to be believed. Considering the Russians eventually sent 5 MIG-31's after the SR-71 at once, looks like the Russians were still looking for a way to stop the famous spy plane. This is a plane designed in the fifties.
Russian computer hardware is far, far behind U.S. computer systems, and that makes all the difference in the world.
The fact pretty much destroys Russian claims of superior military hardware.

No, the article you claim that states that electronics can not be shielded from EMP, deos not state this, they only claim that the U.S. has slacked off on shielding and hardening their electronics.
All this talk about EMP doesn't detract from the fact that when U.S. engineers and scientists got a look at Russian electronics on their MIG-25 back in the mid seventies, it was a joke how far behind U.S. technology the Russians were. In the mid seventies the USSR was literally twenty years behind U.S. technology. Spin all you want, but this is the reality.
As far as MIG-31 superior microwave systems and radar, it was proven long ago that passive enemy detection is a far superior method. We don't need super advanced fighters to take long range shots at enemey aircraft. With U.S.'s far superior detection systems, we can use far less expensive aircraft to take long range shots at approaching enemy aircraft, and our accuracy and guidance are FAR, FAR superior to anything the Russians have. What few advanced Russian fighters and Attack aircraft make it through our long range attack will then have to deal with our far more advanced fighter aircraft.
Claims that Russian logic and software on their far inferior computers systems are so superior to the west to make up the difference is more than wishful thinking, it is pure fantasy. You really make yourself look bad with these claims.
Computers allow not only better control, but better instrumentation, therefore better sensors, better development of metalic/ceramic structures, and fusion of systems. Advanced computers allow integration of systems to a far greater degree. Not only do computers give us an advantage in operating our advance miltary technology, they allow us to build far superior equipment, by given us far, far superior analysis of testing results, greatly enhanced control over production and manufacturing processes, and advance analysis for design possibilities in the first place.
Advances in U.S. computing science put the U.S. so far ahead of the Russians, it will take the Russians several decades to begin to catch up, if that will ever be possible. Because of our open society and economic success, the U.S. attracts the best talent from around the world.
Claims that the Russians have made large leaps in technology, enabling them to compete with the U.S. in military capabilities once again are a complete joke.
