When are the Chinese and the Yanks going to realise that stealth technology is old hat and it is no longer "stealth" technology. Modern Radar can pick up stealth aircraft, or at least BAE systems Radar can anyway.

They tried to get the AL-41 engines from Russia, but Russia wouldn't sell them, so it's speculated that they went with the Russian RD-33, which was first produced in 1981. It's been upgraded repeatedly, and it's not a bad engine, but some of the things I've heard from Russian pilots about their engines is a little on the scary side, to put it mildly. One told me that when they are flying the AN-124, they sit at the end of the runway, with brakes locked, at full power for two minutes. If they don't lose an engine, they take off.

And the new generation stealth isn't just radar. When are people going to realize that stealth is evolving as fast as the radar is? They're into visual stealth, and multifrequency stealth now. Any low frequency radar will detect early stealth, but it won't do much good if you can't shoot them, which you can't from that type of radar.

That is not quite correct, from what I understand the BAE Radar operates using complex algorithms that look to detect the absence of a radar return rather than a radar return. They can use this in exactly the same way as traditional Radar, and as the Rapier II ground to air has proven in the past, they can lock surface to air missiles on the "stealth" aircraft.

The big problem with the "big story" about the Rapier locking on is that the stealth it was locked on to wasn't using the systems that they would be using in real combat. There is a lot that isn't allowed to be turned on unless it's actual war, even against other US pilots in training in the US with no one else around. There is a lot that was on the F-117, and the B-2 that will aid in defeating radar systems, no matter how good they are. The countermeasures advance as fast as the radar.

About 7 or 8 years ago, I was reading an article, that has since disappeared, in which someone working on a DOD project talked about how much farther advanced stealth really is, and what they were working on then, and it's much better than people realize.

One thing you are unlikely to be able to ever fully cover is the infra red trace your aircraft makes. Regardless of the Radar counter measures, your aircraft will always kick out some heat, clever exhaust system or not,

Thats true, but if you fly a B-2 or an F-22 within detection range of an IR sensor in a wartime scenario you deserve to get shot down.

You don't have to be undetected all the way in. Just undetected to the point you can release your weapons and break away.

They don't have to completely cover it. Just hide enough of it so that by the time they are detected (in the F-22 or F-35 case) they have already gotten a shot off, or in the B-2 case, have dropped their weapons. Although from what I hear IR stealth is pretty damn far along as well. It's an interesting game to follow this one.

That IS NOT A CHARGER!The best were made in 68-70 nothing worth a damn since.

This is true, but IR attenuates a lot faster through the atmosphere than radio frequencies.
