Its not true - that US stealth is compromised.

What is true, the new J20 from China and the new Pak FA fighter from Russia both invest heavily into steath because they also know its critical and mandatory in the new era. can you imagine how much a non steath aircraft sticks out on one of these new super sharp radars?

Also, steath isn't jsut 'seeing' the enimy. Rafale, Eurofighter, and US F16's and F18's all tell stories that they can get an F22 in their sights but the radar wont lock on. At that point you need visual camera or IR.. or a combination like the Russians use, OR the full EO DAS system used by the F35. Once again, the US is better at detecting steath than anyone else. Not to mention that LM and company have stated for a long time that its much easier to build a steath detecting radar then a steath plane.

The IR crosssection from the F-22 isn't enough for a ground based IR missile attack. The only way to land an IR missile into an F-22 is to have it on supercruise and have someone come up right behind it and plant an IR Heatseeking missile right into it.

Then again it was never known if it exists. But if it did use pulse/ram jets, those wouldn't be able to operate in space. Supposedly it could hit Mach 4-6 at least based on reports by an expert.
Officially, I don’t think the top speed of the SR-71 was ever said to be faster than mach 3.2. However, it is rumored that it achieved mach 6.

From all of the information I've read and documentaries I've seen, it's not just the shape of the stealth fighters and bombers that keep it off of radar, it's also the paint. They use some kind of specially formulated paint with micro-beads of some sort that help absorb radar.

The UK announced earlier in the year that they are prototyping an unmanned stealth fighter. The issue here is that there will definitely be sorties where they are beneficial, but having an actual pilot with instincts that kick in during the heat of battle will never be beaten my a computer...

It is always cat and mouse. Generally speaking the bigger economy will have the better gear. Keep that economic advantage and all other things being equal you'll have a hardware advantage.

England as a much better war fighting military than China.. and they have am uch smaller economy. There is something to be said for a legacy in defence, same with German and France. They have been fighting more modern era wars than China and India. I do see your point and agree for the most part, but its like nature vs. nurture - both are important.

It's called radar cross section (RCS). It's the effective area the radar recieves after the microwaves bounce back from the target. Most US stealth is based on the radar absorption paint, but some aircraft such as the F-117 rely both on the paint and shape to reflect the EM waves away from the recieving radar. Minimizing the RCS can allow the aircraft to blend into the noise or look effectively like a bird.

The problem with radar absorption paint is that it only works on certain frequency ranges. A lot of R&D is put in to increasing these ranges. Luckily there are certain frequency ranges that are absorbed by atmospheric conditions making them non-ideal for scanning radars.

Stealth technology on fighters is just to increase survivability of the aircraft. With the increasing trend of using UAVs the need for stealth is not as important because there is no loss of human life. The losses will still contain the cost of the aircraft and the technology it contains so R&D will likely not stop entirely.

Not to mention warfare is being fought on other new fronts as well. Cyberwarfare is something that is just as important if not more important than physical warfare in the technological world we live in today. If anything there isn't enough funding to devote the same kind of attention in certain areas of technology.
