Subject: Countdown to Crying

How broken up will some StrategyPage posters be when the F-35 program office finally reveals the F-35 elecronic warfare suite will include not only state-of-the-art ESM but also state-of-the-art ECM, ECM that will include not only the very powerful X-band jamming capabilities that will be found in the APG-81 AESA radar, but also include both on-board jamming and towed decoys? If that day arrives, then so much for the F-35 "only" having an RCS of something like 0.002dBsm using "only" passive stealth (which of course already won't be the case in X-band). Won't it be funny if everyone sees that the formula for success with the F-35 is VLO + ECM = nearly invisible to RF? I admit I'll be disappointed if this doesn't turn out to be true... but I also admit I'm going to be ROFLMAO if it does turn out to be true. Keep your eyes on Electronics & Integrated Solutions, which both makes the latest ALE-55 towed decoy and also happens to be "responsible for the F-35's electronic warfare suite and is also providing advanced, low-observable aperatures and countermeasure systems."

It's amusing how FS can write a 20-line post which contains absolutely no valid arguments against what I said.  On technical merits, he clearly doesn't know anything about Falcon Edge.  The rest is totally irrelevant, since whether or not the UAE gets the source code for it has absolutely no bearing on the system's quality.  Did the UAE get the source code to the IMEWS suite on the M2K-9?  Would they have gotten the source code to the "not full modes" Spectra if they had bought Rafale?

The obvious point, which FS must have missed, is that Falcon Edge is a state of the art EW suite which the U.S. happily developed and exported even though we don't presently use it ourselves.  There is thus no reason to suppose we wouldn't do the equivalent for a F-35 customer.

You miss the point that internal jammer capability is very good also for BVR AtoA.
And you don't carry an external pod for AtoA.
And it is why USAF added internal jammer for F15 (and probably after experienced massive losses vs M2000 in AtoA combat exercise in the nineties where F15 radar were simply unable to lock on M2000 due to its internal ECM leading to massive 30:1 ratio in AtoA combat for M2000)
But the BVR combat is for dedicated F15 wings in USAF even F16 have BVR capability.
 
I sayit again, AESA radar jammer capability is a nice to have which is well marketed by radar builders but a very marginal one since narrow band (covering only a part of X band).
It does not replace a real jammer and would be almost useless unless it cover the russian BVR AMRAAMsky band at least.
Again ignorants believes easily defense marketing.

F-15s have had internal ECM since the beginning.  The F-15A was the first fighter with a fully internal electronic warfare suite, including RWR, RF and IR missile launch detectors, and internal jammer.  Not bad for 1972.

(and probably after experienced massive losses vs M2000 in AtoA combat exercise in the nineties where F15 radar were simply unable to lock on M2000 due to its internal ECM leading to massive 30:1 ratio in AtoA combat for M2000)

Uh huh.  I keep reading these claims on message boards.  Can you cite evidence of these awesome kill ratios?

An AESA radar jammer is pretty much ideal for BVR combat.  It covers the needed band by definition, it has far more power available than any other type of built-in defensive ECM, and it has the most useful field of regard.  It can jam the opponent's X-band missile and air to air radar, and that's all that matters.  Nobody cares about jamming L- or S-band AEW radar if the fighters the AEW controls are all dead.

Herald1234    Its refreshing to see that FS continues to be foolish.   10/16/2007 2:09:51 PM
and nobody can accuse me of being involved.

Keep it up, poseur1. My laughter continues.

It was described in an Air Et Cosmos (paper) article on Red Flag (in 1992 or 1996 if I remember well)  and well known in fighter community.I think it is in those Red Flag where french pilots achieved incredible results which shocked USAF.
A French pilot has achieved a 33 to 1 ratio and all french pilots were in the top 12 pilots among 350 pilots including USAF or British..A legacy of M2000 C-RDI in the 1990-1994 period were it was unmatched. (after it was different with AMRAAM introduction and other US improvements -
Don't think there is any nationalism.Just to mention that sometime we have superior systems)
 
Obvioulsy you have non contact in F 15 fighter community on nineties or you would know that.
 
On F15 A there was no jammer it seems (only pods available).AN/ALQ 135 was for F15C
Prove otherwize and give name of the system
 
BTW you did not understood what I said in former post on UAE F16 (as usual )
Without a competitor , there is few chance that USAF sell a better system than they have.
Document underline that it was the first time due to Rafale competition and it was the reason I provide the socreboard and the link.
If a F35 is on par or an evolved Rafale or better on stealth, there is no chance US would sell a super F35 only for export.
You have really difficulties in reading and understanding, it seems.
ANd of course I know evertyhing which is public on Grumman falcon edge ECM suit.Quite similar to rafale one but not integrated on a LO aircraft (you had only a 3 B$ R&D budget to develop F16 block 60).
So no RCS pattern management combined with ECM.

Phaid is an amateur like you Herald, but unless you he doesn't insult and admit sometime he was wrong like on MMIC for rafale spectra.
I never lie.

You just did, poseur1, at least  twice.

Have a nice day.

Phaid, 
 
As always, everything you've said in the last several posts in right on target and shows you have an intimate knowledge of this subject. 
 
I agree that the UAE F-16 Block 60 sale and the F-15S/K/etc. sales show that if we want to we will sell aircraft with internal ECM equal or superior to what our own aircraft carry. Naturally, if there is no threat that justifies such advanced capability, then there's less reason to sell equipment that sophisticated, so export F-35 may not need to carry better ECM than American F-35. That's what happens when the aircraft's passive RCS is so small that there is insufficient threat to justify needing to add all that extra electronics. And since the biggest increase in threat to us or any F-35 foreign sales customer that could potentially emerge in the next five years or so would be if the French manage to sell some Rafale to a country that is a threat to whoever buys our F-35s, we both know that means there won't be any increase in threat levels any time soon. 
 
I don't know off-hand whether the original F-15As back 30 years ago started out with internal ECM, but I don't doubt you and anyway, who cares about back then when we're talking about combat today and what the F-35 might carry? Certainly since the 1990's the F-15C and F-15E have had the AN/ALQ-135, and those are the only versions we fly anymore, anyway. (Unless maybe there's still a few ANG F-15As still flying?) The F-16s and F-18s, being non-stealthy, carry ECM/towed decoy pods and once again can also count on significant EW support from off-board jammers. 
 
Of course you are right on target regarding X-band and BVR combat. This is by far the most important frequency range of interest, covering the large majority of threat AI radars and missile active radars, like the R-77. Considering again our system of systems and overall situational awareness jamming the forward arc in X-band will be the lion's share of all jamming needs for BVR. And again I will be laughing my ass off if/when it turns out F-35 will have towed decoys as well, and thus can very capably defend itself from all aspects even if an enemy ever manages to lock up and engage an F-35 from the flank or rear.

Phaid/Herald,

To clarify I meant with regard to the F-35, because of its stealth which allows it to evade or even disregard more distant potential threats from the flanks and rear that could engage a non-stealthy jet.
