The IRQ-170 Sentinel is our LATEST STEALTH model, built using the B-2 Spirit design.

The RQ-170 Sentinel costs $6 million, in 2011 dollars.

The B-2A Spirit costs $1.07 billion, in 2011 dollars.

“The pilot is uncounted for.”

Thanks for the laugh!

It was just what I needed!

Cheers!

Anything that uses radio waves can be intercepted, recorded, analyzed, decoded and used. Just matter of time.,

This is not quite correct. RPVs are mostly autonomous and human intervention is quite limited. Satellite links provide data transmission back to the ground operator. You can bet that command and control signals, as well as data are all encrypted, and if the Iranians are breaking these kinds of codes and exploiting them in real time, then some folks at NSA need to be fired. Jamming does not good because the system is designed assuming that it will be jammed, which is why flight is mostly autonomous.

It was a general statement about anything that goes over the airwaves and it is true. Measures to minimize the interference and/or overtaking are used, but at some point direct communication (video/firing) are required and that's where the vulnerability exists. Encryption is helpful, but anything that is encrypted can be "unencrypted" just matter of time. With SDR technology it is much easier than back in the WWII days.
Relying on new RF technology (satellites, GPS, Cell phones) is fine in time of peace. When war, EMP or disasters strike, it is back to good old HF, VHF, tube radios and smoke signals :-)

Probably?

The point, man, is that you have stated nothing not known to the designers. Hi-value RPVs are designed assuming that they will be interferred with, malisciously.

A good encryption system cannot be decrypted in real time as would be necessary to interfere with the operation of any tactical signal.

I grew up doing morse code transmissions, but it is obsolete because modern communications technology is much more reliable. Interference, etc., degrades the bandwidth of transmissions, but error correction, etc. makes this much more reliable than old fashioned teletype or morse code. You think the telephone company does not have to deal with intereference all the time just to get your telephone call through? The good old days of vacuum tubes were not such good old days. I was there.

Finally, EMP is a whole ‘nuther ball game. A high altitude burst to take out satellites, to the extent it would actually work, would invite just one response from the US.

And what, pray tell, would Obama's response be?

All kinds of double and triple postings showing up on my computer. Anyone else? Your post came through three times.

FR had server problems last night, posters that refreshed often had repeat posts.

Here is the proof to my statements earlier (Iranians hacked and took control of the drone)

From article in christian science monitor:
http://www.csmonitor.com/World/Middle-East/2011/1215/Exclusive-Iran-hijacked-US-drone-says-Iranian-engineer

Iran guided the CIA’s “lost” stealth drone to an intact landing inside hostile territory by exploiting a navigational weakness long-known to the US military, according to an Iranian engineer now working on the captured drone’s systems inside Iran.

Iranian electronic warfare specialists were able to cut off communications links of the American bat-wing RQ-170 Sentinel, says the engineer, who works for one of many Iranian military and civilian teams currently trying to unravel the drone’s stealth and intelligence secrets, and who could not be named for his safety.

Using knowledge gleaned from previous downed American drones and a technique proudly claimed by Iranian commanders in September, the Iranian specialists then reconfigured the drone’s GPS coordinates to make it land in Iran at what the drone thought was its actual home base in Afghanistan.

“The GPS navigation is the weakest point,” the Iranian engineer told the Monitor, giving the most detailed description yet published of Iran’s “electronic ambush” of the highly classified US drone. “By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.”

The “spoofing” technique that the Iranians used – which took into account precise landing altitudes, as well as latitudinal and longitudinal data – made the drone “land on its own where we wanted it to, without having to crack the remote-control signals and communications” from the US control center, says the engineer.
