Beijing secretly fires lasers to disable US satellites
By Francis Harris in Washington
(Filed: 26/09/2006)

China has secretly fired powerful laser weapons designed to disable American spy satellites by "blinding" their sensitive surveillance devices, it was reported yesterday.

How it works

The hitherto unreported attacks have been kept secret by the Bush administration for fear that it would damage attempts to co-opt China in diplomatic offensives against North Korea and Iran.

Sources told the military affairs publication Defense News that there had been a fierce internal battle within Washington over whether to make the attacks public. In the end, the Pentagon's annual assessment of the growing Chinese military build-up barely mentioned the threat.

"After a contentious debate, the White House directed the Pentagon to limit its concern to one line," Defense News said.

The document said that China could blind American satellites with a ground-based laser firing a beam of light to prevent spy photography as they pass over China.

According to senior American officials: "China not only has the capability, but has exercised it." American satellites like the giant Keyhole craft have come under attack "several times" in recent years.

Although the Chinese tests do not aim to destroy American satellites, the laser attacks could make them useless over Chinese territory.

The American military has been so alarmed by the Chinese activity that it has begun test attacks against its own satellites to determine the severity of the threat.

Satellites are especially vulnerable to attack because they have predetermined orbits, allowing an enemy to know where they will appear.

"The Chinese are very strategically minded and are extremely active in this arena. They really believe all the stuff written in the 1980s about the high frontier," said one senior former Pentagon official.

There has been increasing alarm in parts of the American military establishment over China's growing military ambitions.

Military experts have already noted that Chinese military expenditure is increasingly designed to challenge American military pre-eminence by investing in weaponry that can attack key systems such as aircraft carriers and satellites.

At the same time, China is engaged in a large-scale espionage effort against American high-tech firms working on projects such as the multibillion-pound DD(X) destroyer programme.

Several spy rings have been cracked and the FBI is increasing the number of counter-intelligence staff tracking the Chinese effort.

Sweet. I love releasing reports like this so that not only China, but the whole world knows that China is successfully blinding our satellites.

Thanks unnamed American officials!

Sorry, I'll take disclosure any day over the cloak and dagger Cold War games.

Modern staelittes wouldn't have this issue, only the older ones. They have to know it's coming. We could have one that swings in orbit that they are aware of (old school), and several others slowly shifting positions as needed that they have no clue exist.

Heck, weather and climatology surveying satellites can do that these days remotely controlled from the ground.

I don't mind disclosure on matters of public interest, but whether or not another country can blind satellites doesn't qualify.

The Russians were doing this in the 1980s iirc.

****. I gotta hide this idea of putting jam on bread. Someone else might start doing it too.

Barf:But won't their radar see us coming.
Lone Starr: not if we Jam it!
Dark Helmet: Raspberry. There's only one man who would dare give me the raspberry: Lone Star!

The Israeli's have been wondering about similar methods for a while, since Iran is/has launched sateliites that could be used for spying.

And we want our own anti satellite lasers as well

Heres a old 2000 article on the subject

http://www.fas.org/spp/starwars/program/news00/000105-asat.htm

Notice the Air Force General mentioned? Thats right, future Chairman of Joint Chiefs of Staff Myer.

A most likely biased article on ASAT system developement history

I dont want to sound like a conspiracy theororist but if i were the government and some reporter wanted to write this little story, I would probably let him do it because I already know that we already designed ways to circumvent this 'blinding' so why not make them feel like they have an upperhand, otherwise the story may never have come out :D

Completely agree, they wouldn't have let this out if it actually was hurting our spying. I'm guessing the Chinese know that as well.

You also can't blame them for trying to blind the satellites, we would do the same thing.

Yeah but we have the Space Shuttle. We could go up, moon the camera, then stick a piece of chewing gum on the lens. :b

Pfft, I've been blinding the spy satellites that fly over my house by putting tin foil on my roof for the past few years!

Hey, MacArthur wanted to do it back in the 1950's. Stopped short by damn-fool bureaucracies! Would have wiped those commies off the map decades ago.

China's doing a nice job of it all by themselves. Economic revolution has eked its way in. Damn Westerners and their blasted capitalism!

Yeah, companies like Google and MS. Oh, wait. Those are companies helping the chinese government bootheel on the throuat of any dissenters. I guess they don't mind THOSE western capitalists.

I think we're all missing the big picture here:

Were they shark-mounted lasers?

Just put moveable mirrors on the satellite..then have the mirrors reflect the laser back to China...then make it spell out.
