Crap. First shot enables you to drive the fight. If you are on a winning timeline, and the adversary appreciates the capabilities of your missile, they have to react. They'll try to slow down the intercept to get their own missile within range, but if you take the shot in the right zone, and with effective mutual support (and the new tactical opportunities that AIM-120D offer), the SU-35 won't win against an F-22. Things become more interesting in 4 to 4.5 gen fight though.

How long does it take to enter HOJ? How does the the Su-35 magically "slip" outside the engagement envelope? If the shot was valid kinematically, the only thing the target can do is so totally confuse the seeker head that it misses. It won't "slip" outside the "interception arc" (whatever that is!).

Actually, it's called proportional navigation guidance logic, and it's a trajectory. Your throwing rock analogy is more akin to lead angle guidance (or even half-rectified lead angle that some older systems use so that they don't lose target lock). And missiles don't take off behind you. Even high off-boresight missiles like AIM-9X go forward first before manouevering.
There isn't a single semi-active air to air missile integrated onto the F-22 (or the F-35 for that matter). Even us poor Aussies fly almost exclusively with an active/IR mix on our Hornets. And if you think that the AA-12 is in any way comparable to the AIM-120 in anything other than the fact that they are both active air to air missiles, then you really don't know anything about air combat.
Guess you've never heard of kill rules, and how they are used in exercises. They certainly aren't "you shoot - they die". And if it's ok by you, I'll trust the modelling and sim results and user briefs over your AMRAAM assessment. After the rest of your post, I'm not sure if you are talking about the right missile...

You have to remember that, essentially, the F-22 is 20 years old. Radars from 20 years ago are functionally similar, but the filtering capabilities are all together different.
At this point, geometry of the aircraft begins to play a more significant role in the return signature than the material it is made of or the surface area exposed. Remember that a property of all moving magnetic fields (radios, radar, magnets, etc) is that they induce an electric current in all conducting materials that is 180 degrees out-of-phase with the source. That means... guess what... your plane becomes a giant antenna - so do all structures inside of it (assuming they are not shielded against EMF). That means stealth technology goes well beyond the skin of the aircraft, and goes to the internal structure, the way the internal components are shielded, etc. You could build an aircraft out of composite materials and have a larger RCS than a similar aircraft that had an aluminum or titanium-based airframe.
The U.S. made their investment in stealth technology based on two main ideas - first, that radars would always have to filter out small radar returns, and second that control of digital processing components would be assured to contain the spread of the necessary capability for radars that could endanger stealth aircraft.
However, it means the face of "Stealth" must change. Radar, while being an important concern, is no longer the primary concern. Modern jamming, countermeasures, and passive reduction ("Stealth") technologies essentially ensure that any two aircraft will have to close to a "merger" before being able to score a kill.
Optical and Infra-Red reduction methods are where the future of "Stealth" is.
Yeah - against drones.
That is semi-active, genius.
It can take a few seconds for the missile to figure out it's being jammed. A few seconds is all it takes.
The AMRAAM has a "beam-riding" Semi-Active mode similar to the AIM-7. And they are quite effective as jamming is harder than hell - since it's essentially a modified form of anti-radiation mode (and the host aircraft is supplying the radiation against the will of the target aircraft).
Assuming a reasonable scenario - AWACS will ensure the F-22 doesn't get into any nice little zones without the 35s knowing. Even still, that isn't necessary, once those 22s turn their microwaves on, the 35s have a few seconds to adjust and pop a shot or two off.
I often try and assume that there are people reading this who have no clue what the hell a missile datalink is - let alone the dynamics of missile flight.
LMAO
Stand by - links to follow.
Houses six radar-guided AIM-120C advanced medium-range air-to-air missiles (or two 1,000-lb class GBU-32 Joint Direct Attack Munitions in place of four of the AIM-120Cs) in the main weapons bay
Carries two heat-seeking AIM-9 Sidewinder short-range air-to-air missiles in side weapons bays (one in each bay)
A single M61A2 20-mm multibarrel cannon
Four external stations can carry additional stores (weapons or fuel tanks)
Gun system (Linear Linkless Ammunition Handling System) capable of feeding ammunition at rate of 100 rounds per second
It's exaggerated on the side of "caution." You want your aircraft and pilots to come home at the end of the day regardless if their target got away because they didn't capitalize on that extra second and a half to ensure a kill when their own aircraft was in danger.
Pilots will push it to the limit anyway - so you simulate on the cautious side.

It's fully capable of SARH. It's extremely difficult to jam - and that is why it's been held on to.
LinkThe F-22 showcased its advantages of stealth, supercruise, maneuverability, and sensor fusion during the exercise. This Red Flag was a first exposure for many participants to the Raptor’s capabilities. For those flying against the new fighter, the experience was often frustrating. "I can’t see the [expletive deleted] thing," said RAAF Squadron Leader Stephen Chappell, an exchange F-15 pilot in the 65th Aggressor Squadron at Nellis. "It won’t let me put a weapon on it, even when I can see it visually through the canopy. [Flying against the F-22] annoys the hell out of me."

In Gulf 1 the kill ratio was crap.

I think his point was it relies on the firing aircraft's radar to guide it initially. It is essentially semi-active, only the receiver is on the firing a/c, not the missile.
Do the SM2 series not have IR seekers?
They may not be the primary guidance mode, I'm not sure.
Which is different from AMRAAM how?
Kinematically, the AA-12 bleeds less energy than the AMRAAM in manouvering.
Lattice are better than fins in that respect.
Actually, the big part of stealth that I like to get at is its effectiveness at decreasing the range at which a usable return can be found.
I'm sorry I didn't make that clear enough in the post. I just kind of wanted to break up the discussion about the overall effectiveness of stealth by either logic or by producing another target
-Are radio waves moving magnetic fields (The whole EM radiation thing is not quite settled in my brain yet, so I'm not sure if it could be called a field or not as it's been explained to me as a radiation wave)?
-If it can be counted as a magnetic field, I understand that it can induce an electric current a la antennae, but wouldn't the receiving structure need to be the proper length so as to match up the resonating frequency with that of the incoming wave? What is the likelihood of that?
While at medium ranges, you're absolutely right, the radars would be able to detect the F-22, isn't the long-range fight the more (and I loath this word, believe me) important to consider?
Hmm... I had thought we just finished discussing how radar recognition and processing power had progressed to the point where it became possible to pick out the details showing that an aircraft is present in the swath of garbage present in the atmosphere with or without jamming involved? Sorry if I'm misunderstanding, here, it wouldn't be surprising of me to misinterpret what you were arguing for/against.
How does one expect to disguise the massive jet plume and heat signatures caused by engines that run simply by adding warmth to air for propulsion?
No, I said in exercises, not missile tests. If you don't even understand basic terminology like this, you really don't have a clue what you are talking about.
Wrong again. I'll even give you a little help this time. Have a read of this link's description of semi-active Link, then come back and tell where in the AMRAAM engagement profile the missile receives the radar return from the target based on the emissions of the launch aircraft.
It is called mid-course updates, and is not defined as semi-active.
Only if the missile was fired at Rmax beak to beak, in which case jamming is irrelevant anyway because manoeuvre alone could defeat the missile kinematically anyway. Your scenario makes no sense at all.
Absolute, total and complete rubbish. Show me one credible link that describes the AMRAAM as having a "beam-riding Semi-Active mode". Look, read this AMRAAMarticle (though Wikipedia, it actually isn't too bad), because you seriously seem to not understand the basics of the missile and how it works.
Again, you really don't understand how an AESA works, do you? And what shots are the 35s "popping" off? Passive? If so, then again show me an effective passive air to air missile (especially against AESA). Active? Using what cueing? IR? What missile and range (and cueing)? Give us some details of your scenario, rather than assumptions.
Your source is wrong, which is probably why you are wrong if this is the most exposure you've had to the missile. Here's another link, this time from the manufacturer of the missile, who you would think would know their missile and use the right terminology. Raytheon. Read the article and tell me if you find the term semi-active anywhere (or just do a word search on semi-active). Find anything? No? Wonder why?
Well you're doing them a disservice because your understanding of the subject matter is terrible.
AIM-120 = Active
AIM-9=IR
Wow, no semi-active missile listed. Looks like you were wrong - again...
No, you simulate on the side of reality. Kill rules are constantly finessed based on trials and modelling and simulation outcomes so that aircrew get the best understanding of their weapon system, and employ it effectively during operations.

This doesn't offer much as it doesn't give a number of shots per kill assessment. Best I can offer is that I am personally comfortable with the missile and its capabilities.
Just to re-iterate, I said "effective passive radar homing air to air missile (or even surface to air missile)". An IR seeker is not passive radar homing. I'm talking about a HARM-like missile optomised for anti-air.

HOJ is a different kettle of fish to what I was suggesting. I was talking about guiding on the normal radar emissions of the fire control radar, not jamming. I know the answer, and it is that it was (is) hard enough to do against a traditional pulse doppler radar with a single transmit/receive capability, let alone an AESA with multiple T/R elements.

I understand air combat quite well. I know what is going on under the hood of those aircraft, and I also know that our equipment is designed to counter Soviet designs from the 80s.
I review and reenact air combat strategies and take different factors (such as different EW capabilities) into account.
And as for passive guidance - it would only be accurate used as a mid-course update.
