the only stealth aircraft I know of that have been used in combat are the F-117 and B-2.
one F-117 was shot down during the Serbian war. But it was determined that the reason was mission planners had them performing the same mission every night for several nights at the same time. This was a violation of protocols that allowed the aircraft to be shot down.
Called 'spray and pray' and given the truth presented, it was a statistical inevitability that at least one F-117 will be a casualty of this 'spray and pray' tactic. There is nothing for US to regret about developing 'stealth' technology. The concept worked in combat and beyond anyone's expectations.
And how is it they tested the radars effectiveness at tracking stealth aircraft when they do not even have a stealth aircraft on the level of say the B-2 bomber or F-22. Computer simulations? Sorry but computer simulations are not always right.
This kind of logical thought process and critical thinking skills are sorely lacking in these forums.
================================
so then given me proof that any stealth aircraft of the usa has EVER been up against a S-300 or more interestingly a S-400
Here is what you and so many others who sucked up to Russian and Chinese junks failed to understand about radar and 'stealth'...
That is called a 'radar range'.
That is a
FULL SCALE model of an A-12/SR-71.
For the A-12/SR-71 model above, why are the vertical stabs not installed and the model is upside down at that? A valid speculation could be that they wanted to see the differences between a clean fuselage versus one with the stabs installed. The data collected could determine the optimum angle for the stabs for the final version. But the point is that in radar range testing, a radar pulse is just as good as a bullet or a missile and the only difference is that after a radar pulse 'hit' we can select the 'reset' button on the aircraft's design, go back to the drawing board and re-do the design.
The behaviors of radar waves on a single surface is not unknown. But on different dimensions of surfaces and finally on a body, which is a collection of surfaces with varying dimensions, we mastered the radar range testing process. The Russians have not. So yes...Based upon the B-2's and the F-117's combat record, we have a better than good estimation of how the F-22 and F-35 will fare against the S-300 and S-400. Neither the Russians nor the Chinese have even a functional
FLYING model of the F-117's equivalent. A fully functional flying model is crucial in that the aircraft will present different aspects of itself to the transmitter(s) at different speeds and altitudes. Radar range testing will include multiple transmitters at different locations to establish baseline RCS figures. Then the flight figures will be compared against the baseline figures to see if any modifications are necessary.
Go back to the radar range facility image and take note of the concrete pattern. Those are deliberate designs to minimize ground reflections that could influence the result of the model mounted on the pylon. That level of detail is equally crucial as a flying model of a design. Without radar range testing, and such testing is
NOT confined to aircrafts, any claim about any radar system or aircraft should be under suspicion. A missile battery's radar could be removed from the truck, transported to a radar range facility, baseline figures are established for the system's performance against various models of varying sizes, the radar system then is reinstalled to the truck and the whole thing sent out to an actual flying base to test against flying aircrafts.
For the B-2, F-117, F-22 and F-35, their performance against the best of US radars, from Air Force to Army to Navy, are classified. But now you know, just a fraction, what is truly involved in radar testing these 'stealth' aircrafts may be you should not be so gullible about Russian or Chinese claim on their junks.
