    Ok, what does this mean, then??

    It means that you post responses to what you think I said, and then I end up having to try and defend against an assertion that I never made.

    How does prop. guided missile need not to match target’s maneuvering, then???

    (For a target flying around collateral vector, it’s a beam riding that actually works better.
    It’s only for a target at high aspect, that prop. guidance pays out.
    However, since this is the most common posture a defending plane takes when shot upon, the guidance type has been chosen in an attempt to counter just that.
    )

    I don’t know how we’re still on this. Once again, my whole supposition has never been that a missile doesn’t have to change course enroute to a target. It’s been that using Pro-nav, the way it follows a target uses optimized profiles, using the best geometries to maintain a high energy state.

    I see. So much about putting words in ppl. mouths.
    The example of 30km is just that, an example and I don’t think any MAWS today can detect an AIM, at 30km, but can be wrong…dunno and that doesn’t matter, after all.

    I understand this. My response was for Obligatory, not you, since he was the one that posted the link about the MAW 300, and gave a percentage. I was pointing out that his link gave no ranges, so that to assume your range was accurate was highly speculative.

    If the missile didn’t fizzle, then the engine did ignite, and was consequently detected.
    DAS has nothing over other any other passive MAWS in the context of detecting missile ignition.
    “DAS is basically missile launch detectors,” Beesely said.

    MAWS is different than MLD, and DAS is a lot more than either of those. Secondly, the engine of an AAM is considerably smaller, and with a short duration burn vs. a ballistic missile. It’s like the difference between watching a fireworks show vs. a space shuttle launch.

    There’s everything contradictory in that post.
    Ww, the missile can’t “conserve” the energy as you apparently think. This isn’t semantics, but misconception and there’s no room for nuance.
    This is why I told you to quantize your claim and fathom how wrong you are.

    I’ll give you this- you’re consistent. You like to put words in my mouth, that I never said, and then attack my position, while patting yourself on the back for being clever. I never said anything about conserving energy, nor do I know what quantizing is. What I did say is that there’s a big difference in the amount of maneuvering required at BVR ranges vs. WVR due to the geometries involved. In other words, the missile will have to pull far fewer Gs when it’s 30-50km away from a target to stay on course for impact, than at 2km.

    How have Obligatory added anything?? You assume way too much.

    I assume nothing. He added a percentage without qualifying it, shortly after you gave a range.

    Besides, how do you know certain MAWS can’t detect missile type target at 30km with 99% certainty?
    I haven’t found a single piece of evidence that would deny or corroborate that myself, but you’re welcome to prove otherwise.

    I’m not in the business of disproving negatives. The burden of proof isn’t on me to prove that something’s not possible.

    How is this possible ?

    You accept a missile can be spotted 800 miles away by MAWS,
    but don’t believe a missile can be spotted 20 miles away by MAWS

    That’s just over 2% the range from an equally hot engine.

    No, I don’t accept that a missile was spotted 800 miles away by a MAWS. You might want to read up on the difference between a MAWS, a MLD, DAS, etc… before mixing them up(as well as the difference between a large ballistic missile and an AAM). What did happen was the the DAS system was able to see the large IR signature of a ballistic missile, whose engines were still on, at 800 miles. That’s considerably different than spotting an AAM, whose engine isn’t on.

    By that we are back to an ordinary bullet, what is aimed to a point where the opponent will appear at the hitting moment. The opponent will not changing course, height, speed a.s.o. Is it about the capability of an AAM only to overcome “aiming errors” by midcource updates?!

    Not at all. My whole point is that at BVR distances, the AAM isn’t going to need to pull 50gs to match a fighter. It won’t be making violent turns until it’s much closer to the target. That’s all I’m saying, nothing more, nothing less.

    Really and who said otherwise? In fact, I think I’ve said that a few posts ago…
    This never was an issue in the first place.
    I think I need to remind you of your original posting:

    This simply isn’t true in semantic or any other way.
    Do you realize why, or we need to expand on that?

    There’s nothing contradictory between either post. That’s where the semantics issue is coming into play. When I say making minor course corrections vs. matching every move a fighter makes, there’s a distinct difference in my meaning. Apparently the nuance there was lost on you.

    And then, you combined that into one single statement and felt a necessity to respond to such a Frankenstein??

    The combination was due to Obligatory’s adding of a percentage to the range you’d given. I was merely pointing out that a MAWS may be able under certain circumstances, detect a missile at 30km, but certainly not with a greater that 99% probability from any azimuth/elevation.

    Once again, to stay on topic, we’re discussing kinematic performance, not electronic/sensor performance, of a missile vs. a maneuvering target. In other words how much course correction a missile needs to make at long distances, to stay oriented at the target vs. at close range.

    Unless one’s foes have HOBS weapons, then the -9M is perfectly fine. It’s still a very capable weapon in the forward sector.

    This would be used to shutdown C4I, IADS, etc…., and used in conjunction with other assets, to provide synergistic effects.

    At long range, it’s not the seeker head of the AAM that’s telling the missile where to go though. Until the missile goes active, it’s getting its guidance via datalink. We’re not discussing countermeasures, field of view, etc… but strictly geometry and kinematics. It’s not until the AAM gets closer to its target, where the angles become more and more challenging.

    Quantize!
    Don’t run into generics, the moment your “knowledge” is put on a test.

    If you can’t understand the spatial relationships between 2 distant objects vs 2 near objects(with one moving 2-3x as fast or more), I’m not really sure what I can tell you that will aid in your understanding. Think of it like this- you have 2 players on either end of a football field, heading towards one another. While there is still a large separation between them, the one on defense can run in circles, or head left/right. The one approaching him needs only to make small changes in direction to keep pointed at that person. Once they’re close, then it becomes necessary to make more significant course changes to stay pointed at the other guy. Now, let’s assume the one on offense can run 3x faster than the other guy that’s running in circles, etc…
    In other words, from a geometric perspective, the angles are much smaller at long range, than in the terminal phase.

    First, who said anything about 99%, at 30km??

    You said 30km, Obligatory said 99%. I was pointing out that those 2 figures may be accurate by themselves, but not necessarily when combined.

    There’s a big difference in 99% detection of missiles at 5-10km vs. 30km though. That’s why I’m asking about the range. Additionally, the fact that the coverage is for azimuth, and not elevation, a lofted profile missile will get much closer before detection, than will one that’s flying directly towards you.

    Astra goes active at 16 miles/25 km, which is roughly equal to it’s max range at tail chase.

    What’s the relevance of the tail chase range? In BVR combat, it’s highly unlikely that one is going to circle behind one’s opponent, and then fire at their tail. Tail chase range is only relevant after the merge. It’s the head on aspect that is more important in BVR. As for going active at 16 miles, that gives an opponent a lot more warning, than an AMRAAM, which doesn’t go active until <10km.

    As a matter of fact it states: Probability of Warning: > 99%

    The MAW-300 (http://products.saabgroup.com/PDBWebNew/Generic.aspx?Entrance=Product&ProductId=1304)

    At what range? It also says that with 4 sensors it has 360deg azimuth coverage. What’s its elevation coverage(i.e. it doesn’t have 360×360 spherical coverage)?

    Apparently, you think so…however, the matter is way beyond semantics.

    I know so. You spend an inordinate amount of time, picking away at my posts, worrying about whether I should’ve said happy or glad, while missing the point altogether.

    Why don’t you try to actually verify this before making such assertion?

    At BVR ranges, the missile is only going to be making minor course corrections, as it will only take small adjustments to keep pointed at a wildly moving target. Once it gets closer, then it will have to turn harder to keep oriented correctly. I’m not sure what’s necessary to verify, as that’s a pretty common sense notion.

    That depends on the missile type and setup, but modern MAWS should reduce missile’s (non-airbreather) Pk way more than enough…

    I don’t doubt modern MAWS is effective. Where we disagree is just how much warning time the pilot is going to have. I have my doubts that an incoming missile, that wasn’t detected by an MLD, will be discovered 30km away(>99% of the time).
