Actually it is the correct assumption, for a whole bunch of reasons, including the fact that usually guidance signals mean someone has launched or is launching on you. Often enough the RWR cannot make that distinction for you, other than to signal 'missile launch' if it receives guidance signals with a certain transmit power (ie. inside lethal range).

??? Did u even listen the interview? This has nothing to do with Serbs and what they knew or didn't knew. He said that because many people ask him how did he get shot down when F117 is stelth (completely invisiable in their heads). Then he said that not even B2's are completely invisiable. And not 'everyone' knows that espetially because in media (both western and eastern) there was created mith of invisibility rather then low obesrvability around stelth planes. Zoltan Dani contributed to this mith when he said that he used modified radar (which is not true).

IMO it is a silly and risky way of assessing enemy missile capabilities - you 'defeat' every brief out of kill-zone non-launch and then are hit by the first pair of real missiles... yet can still claim that hit rate is less than 10% or some such nonsense... even saying that 50% is 'correct' based on one hit from a pair of missiles misses the point that this is one hit from one engagement.

It is silly until you realize that you may not sight all launches, and you have to depend on your sensors.

This could be correct for command guided SAM's in theory, but as deceptive launches (just giving out signals, without actual missile launch) are pretty basic practice during the fight, counting RWR signals would overestimate launched SAM numbers, thus underestimate their effectiveness.

This is completely false in case of SAM's using semi active, or passive guidance.

I doubt this to be true, especially in an environment rife with SEAD, you want to take shots, and make those shots count - but hey, that's just speculation.

This hasn't got anything to do with 'faking out' your opponent, at least AFAIK. It's simply a limitation of what an RWR can do.

Reaction to STT is immediate evasion in the majority of cases. The fact is, in at least some situations you're not going to bother waiting for a launch signal, you will go evasive. Eg. Iraqi MiG-29 flight vs 2 F-15's. The MiG locked up one F-15 at about 4nm range, that F-15 went defensive immediately, while the other F-15 launched an AIM-7 at the same time. You could argue that this was part of a drag and bag tactic (the F-15's were closing to VID because they had some form of EID failure, IIRC), but frankly I wouldn't want to be going head to head with some SARH missile at 4nm. I'd rather drop into the notch then and there and prevent the shot.

There's also a possiblity that you can't tell radar STT from missile shot - ie. perhaps it's always generating an M-link, or perhaps you can't pick up the M-Link. The radar itself doesn't necessarily have to change waveforms to guide a SARH missile.

Again, this has a lot to do with limitations of RWRs AND training.

Loc: you would look here!
I'm sorry, but I don't think we should be underestimating the B-2 and think of it as a bigger F-117. I think that like with the F-22, we probably know only around 10% of what's on the B-2, and the rest is classified. There is a reason why the B-2 is still in service, and the F-117 is not. About that active cancellation thing, I wouldn't be surprised to hear it actually works as advertised, and who knows what else the B-2 packs that we don't know. I personally wouldl expect it to have a system that triangulates radars as well. I'm not saying that SAM Simulator should be trying to guess about these secret things, but just keep that in mind when discussing the B-2 and the F-117 together. I personally have a much higher opinion of the B-2.

THe B-2 isn't anything like a bigger F-117. It has onboard toys that the F-117 did not and could not have.

That's because you don't understand it; it sounds simple (and is simple) in principle, but in practice it's just next to impossible to properly implement outside of a laboratory where you can strictly control your emitter.

That's part of what ESM package.

Please note, that Soviet SAM systems has no STT mode.
SA-1/2/3 are TWS and stays in that mode during engagement, as it has to track 3~4 targets always (1 target + 2~3 missile).
SA-4/8 are monopulse sets
SA-5/6 are just illuminating their target, while their semi active missiles are guiding themselves

Radar triangulation capability is grossly overestimated in the case of '99 Belgrade nighttime bombing.

Approx 6~8 Metric (HARM friendly target acquisition) radars were continuously emitting all around Belgrade.
2~4 (on duty SAM) Centimeter band (fire control) radars were only emitting for a maximum of 20~30 second, during engagement (when target was closer than 15~20km), than moved to another position.
Several Centimeter band IRZ (radar decoy) were emitting and hopping positions during all night.

During B-2A attacks F-15C CAP, and F-16CJ SEAD were usually buzzing around Belgrade.
(So TOT timing was critical.)

The B-2A should overfly downtown anyway, they had to cross the SAM rings, each night.
