Lockheed Martin F-35 Lightning and F-22 'Raptor' : News & Discussion


Should be enough for threat identification and localisation since the EW suite is incapable of electronic attack.
That's been proven false over and over and over again.


Always active, AN/ASQ-239 provides all-aspect, broadband protection to help the F-35 reach well-defended targets and suppress enemy radars. This system stands alone today in its ability to operate in signal-dense environments, providing the aircraft with radio frequency and infrared countermeasures, and rapid response capabilities like no other aircraft. Its platform level design provides improved reliability and maintainability, optimizing long-term lifecycle costs.

The AN/ASQ-239 is also built for the future, with an architecture system that allows new capabilities to be added for the F-35 fifth-generation aircraft. Our Digital Channelized Receiver Techniques Generator and Tuner Insertion Program (DTIP) technology upgrades the AN/ASQ-239 system to enable new capabilities, further improving warfighters' ability to conduct critical missions in contested airspace. This improved EW system delivers the world-class functionality of the previous system in a smaller footprint, reducing volume and power requirements and creating space for future upgrades.


This processor is just one of many, it sits under the main ICP.

Those "countermeasures" refer to CMDS and of course the towed decoy. The F-35 doesn't have electronic attack. And the one that comes with the radar is still in development.

What exactly does 'Techniques Generator' mean in your vocabulary?


5. JAMMING TECHNIQUES GENERATOR The exciter section contains the VCOs and the keyed oscillators, which generate the jamming waveforms that are directed by the system processor. The exciter takes the threat signal from the receiver and modifies it with deception modulation or generates a noise program based on the techniques generator in the system processor. The selected jamming technique is then sent to the transmitter section.

A techniques generator is needed for that, but the emitter can be the radar itself. That's the whole point of the radar getting EA capability, the hardware is already there, just not unlocked yet.

Look, unless they actually spell it out, the F-35 doesn't have ECM because Boeing confirmed that the F-35 doesn't have full spectum ECM capability.

Have you read RISING SUN's last post? I suppose the F-35 has 2 radars now huh?

Full spectrum is a pretty broad brush don't you think. No aircraft has full spectrum capability. That would involve everything from HF to MMW. 'Broadband' is what they say, and that's all any aircraft can claim. Certain frequencies aren't worth jamming because you can't target jacksh1t with them. The enemy has more chance of targeting the jamming source passively than targeting with VHF. So jamming VHF is like using a loudspeaker to tell people to be quiet in a library.

F-22 news: exeunt

General Charles Brown said on 12 May that these platforms will include the Fairchild-Republic A-10 Thunderbolt II close air support (CAS) aircraft as that platform will be around for some time because of a re-winging programme. The fighter mix, he said, will also include the new Next Generation Air Dominance (NGAD) platform, the Lockheed Martin F-35A Lightning II Joint Strike Fighter (JSF), the Boeing F-15EX Eagle II, and the Lockheed Martin F-16 Fighting Falcon.
Notably missing from this list is the Lockheed Martin F-22 Raptor, which is considered the USAF’s most advanced air superiority platform. Gen Brown said additional F-35As could replace the F-16s, an older platform, but that this decision would likely be made six to eight years from now.​

F-35 news: "if we keep lowering our expectations, the JSF will eventually manage to reach them"
“We are effectively at full rate production today,” he said. “Milestone C used to kind of be a departure from the close management of OSD and the services [but] I don’t see us getting away from that. So, really, for me, I don’t sense that the lack of that milestone is doing anything other than providing a launching point for criticism of the program. So for that reason perhaps alone, I would love to get past [it].”​
Paraphrasing: we've launched full-rate production before the we were supposed to, and at this point the only reason I'd care about actually reaching the development milestone we were supposed to reach first is to shut up critics.
“Now we have a cost overrun and we've got some schedule slips on TR3,” Fick said. “As a result of the cost overrun driven by TR3, we've had to slow development and, in some cases, stopped development on some of those Block 4 capabilities.”​
Paraphrasing: "yeah, block 4 will not have all the capabilities it was supposed to have, we had to drop a few of them as part of general corner-cutting, you know? It's not like it's important that the F-35 is actually capable anyway. As long as we sell it, what else matters?"

It's nothing strange for the EW suite to generate jamming signals for the radar to emit. That's the point of sensor fusion anyway. It's all about using one device using the reosurces of another device.

There's nothing strange about aircraft having full spectrum jamming capability. The F-35 gets that using pods, like the NGJ, it's not built into the aircraft. Not even an SPJ beyond firing some chaff and flares, perhaps DIRCM sometime in the future. And a lot of comm jamming happens in VHF and HF, not just L band. And there are VHF and HF radars as well. But typically aircraft carry these in pods anyway. The real ones are mid and high band jamming, which are largely internal.

Unless someone actually comes out and spells it out in detail, Boeing is right, the F-35 simple lacks electronic attack outside the radar and towed decoy. And the radar is still not there yet. Neither is the NGJ available for the F-35, so right now, nada.

So I suppose the F-22 will be retired by 2035, replaced by the NGAD. That's a pretty quick out-of-service date. But it goes to show that they are not going to throw more money at the F-22 anymore. They will perhaps save a lot of money in sustainment costs for an out-of-production jet.

That ALIS news seems BS. "A little better" can mean literally anything. Like we fixed 10 out of 100 problems. But still got 90 left.

And it's unlikely the F-35 is ever going to match the F-16's sustainment costs. They are going to have to live with that.

So what are the 2 technique generators about then? Read his post. They have spelt it out, you just don't want to read. Power supply upgrade for receiving?


No fight aircraft has complete spectrum coverage.

Well, the way I see it, the EW suite identifies enemy signal, creates a response and transmits the response using the radar, towed decoy etc. But the EW suite's antennas themselves are not duplex.

Someone official should very, very, very clearly state that the F-35's EW suite antennas are duplex if one is to believe you. There's nothing strange about an EW suite having a techniques generator. This is useful even for podded transmitters, like the NGJ.

Depends on what you are calling "complete spectrum". Typically fighter jets need to carry 4-18GHz for self-defence in order to protect themselves from FCRs.

LCA Mk2 is expected to carry both low band and high band antennas internally.

This is from 10 years ago. You can clearly see references to low band and high band.

Based on how it's defined, it could be 4-18GHz, if 4-8GHz is considered as low band. Or it could even mean 0.5/1-18GHz since the low band emitters are CW, meant to attack communication systems. Or it could mean 0.5-4GHz (low band) and 8-18GHz (high band), skipping on the 4-8GHz (mid band).

I think it's the last one, since it makes sense that comm systems require smaller antennas whereas C and S band radars will require larger antennas that cannot be carried internally, hence the use of pods.

But with smart skins it should be possible to carry all sorts of antennas internally with large apertures.

Why would there be two if there is only one transmitter? To me they've said it as clearly as possible, but some people just don't want to hear it. You're trying to argue that it generates jamming signals without being able to transmit them now. The radar is a separate system - APG-81, it is not part of AN/ASQ-239 but can be used in conjunction with it. When an article talking about ASQ-239 says 'electronic attack', it means only one thing.

For me, electronic surveillance measures, electronic countermeasures and electronic attack, as specified in the picture referring to ASQ-239 says everything you need to know. Power supply upgrades for receivers? Your argument makes no sense anymore.

None of those frequency ranges would be considered full spectrum. Ka band is up to 40GHz, MMW - 100GHz, VHF - 0.1GHz.

Did you forget AESA are multifunction? Through array choreography, two different signals can be emitted at once using two arrays separated using software.

I'd trust Boeing, who were part of the F-35 program, than just some guy on the internet. Makes sense eh? They in fact made it part of their official presentation, ie, the F-35 does not have any real electronic attack function, "so buy the Growler".

Well, the F-35 doesn't even have that.
