Pakistan - "Ally"

Your ignorance of technology is not our problem. If you read more than Ayn Rand and JK Rowling you would know more.

 

We need them until we can get troop levels in Afghanistan down to 20,000 or so. After that it is a whole new ball game.

 

Two dreamers, why not?

 

There are several technologies used to combat stealth aircraft. Doppler radar that can find the 600 mph bumblebee is one, but it can be spoofed and it still has to be in position to track an exceedingly small object. It is very expensive to site them close enough together that a stealth aircraft could not slip between them. Russia is very, very big.

Optical and IR systems that don't rely on radar are others, but are also subject to spoofing. The French are working on a system that uses no radar at all, but uses regular radio broadcasts bouncing off stealth aircraft to track them. It's a system that is theoretically hard to spoof. But it requires a certain density of strong radio broadcasts. It also requires a huge number of special, very sensitive receivers and a very large, very fast computer network to process the signals in near-real time. Very expensive and vulnerable to hacking.

Stealth technology is known and understood and countermeasure have been developed. The thing is . . . stealth does not and never has rendered an aircraft invisible to sensors. What it does is to make it so difficult to detect that it requires a radar network so big and sophisticated that it is not affordable by anyone in a practical sense.
