Well, I did remember the wrong timeThe date is May 2021.
USMC receives first APG-79(V)4 AESA radar prototype
Raytheon Intelligence & Space has delivered the first APG-79(V)4 active electronically scanned array radar prototype to the USMC for testing on the Boeing F/A-18C/D Hornet multi-role fighterwww.key.aero
Care to explain.
Mouth publicity, of course lie will be the silver bullet. just how you forced to beleive feb27 is actual victory of india.
0.06 is simply a mathematical calculation we came up with because a Dassault engineer said that the frontal RCS of the Rafale is 10-20 times smaller than M2000.
M2000's frontal RCS is 0.8m2. So when we divided it by 10 and 20, we got 0.04m2 and 0.08m2. The average of the two became 0.06m2.
You can see that the Rafale has been designed to have a very low frontal and rear RCS.
In A2A combat, you drop the tanks beforehand, so you are only carrying missiles. Missiles already have low RCS, 0.1m2 or less. And if Rafale gets first look, first shot, then the BVR missiles are expended. WVR missiles have RCS lower than the Rafale's RCS, so they are irrelevant.
Even with the BVR msisiles, 2 are on the fuselage, so they are unlikely to contribute a lot to RCS. So just releasing the BVR missiles on the wing will bring Rafale's RCS back to its normal state. It's the same reason why Typhoon's missiles are recessed into the fuselage. When the Typhoon drops its tanks, its RCS will go back to its normal clean state. You can see the same with KF-21.
When J-10, JF-17 or LCA were designed, such concepts were not incorporated into the design. So the addition of missiles would increase RCS significantly. But the Europeans designed their aircraft to have 0.1m2 class RCS and also designed their missiles and hardpoints in such a way that they didn't increase RCS substantially.
Plus the Europeans had advanced electronics hardware as well. India and China received AESA tech only after the 2000s. But France, Israel, Japan, US etc have had it since the 80s, which is why they introduced it in the 90s and were incorporated into their fighter jets in the 2000s. So managing airframe RCS with sensor design wasn't a problem to them. So what the others did in the 90s, we are doing only now.
Their RCS is so low that it's irrelevant to the total frontal RCS of the Rafale. For example, the IRST may only have an RCS of 0.001m2, or even lower. So 0.06+0.001m2 = 0.061m2 = irrelevant.
Rafale does not have passive stealth, it simply has a very low RCS. So the standards you are looking at is different when compared to J-20, F-35 etc, where the objective is VLO. Rafale achieves LO/VLO capability electronically.
Reducing to -30dBsm is done using active cancellation.
Analyzing Active Cancellation Stealth
Advances in microelectronics may one day make today’s largely theoretical active cancellation stealth techniques for radar more practical.
Active cancellation is not an electronic attack, it's just a copy of your own signal returned to you after the Rafale's echo is removed from it. It will be no different from a signal that's bounced off a bird or dense clouds, so your radar will reject it as clutter (false positive).
But don't worry, it's unlikely that this level of stealth is still present on the IAF's Rafale F3R, it is expected only on Rafale F4. Currently, Rafale's active cancellation is still not impressive enough to compare with passive stealth like the J-20 or F-35. But it should be enough to give it a massive advantage over J-10 and J-11, while providing some level of parity with the current models of the J-20, especially with software upgrades that will come as the F4 is developed.
And by the time the main J-20 variant with the 18T engine becomes operational, and will still take years more to fix problems, you can bet that the IAF will be ready with a fully operational Rafale F4 with LO/VLO capabilities.
Today, you should definitely be worried about whether the PL-15 will be able to defeat the Rafale F3R.
APG-81 is GaAs.
Yeah, GaN on ground radars was released a long time ago.
IAF operationally deployed GaN radars for air defence in 2011 with the EL/M-2084, the IN followed suit with the MF-STAR on destroyers in 2014. Both Israeli tech. So GaN was operational even before that in Israel.
But GaN on fighter jets is becoming operational only now, starting with the Hornet upgrade.

But on 4th gen jets, the effect is not a lot. It does contribute, but if you manage the nose, cockpit and inlets, you can still get 0.1m2 RCS. It has been achieved on Gripen, Typhoon and Rafale after all.
If we go to war today, the jet is advanced enough to punish the enemy with a massive kill ratio. Especially when combined with our new IADS. At the very least, it acts as a powerful deterrent.
5 years from now, it's gonna be more difficult as the Chinese start deploying the J-20 in numbers. But it should continue to provide deterrence alongside the IADS and new inductions, like the LCA Mk1A and MKI MLU.
Post 2030, we will have the F4 coming in. Perhaps stopgap F-35/Su-57s too. But MRFA will give us the numbers and capability necessary. Hence the importance of MRFA. Stealth drones will also become available.
Another average american style citizen....
There are only screws and bolts in common between Rafale A, a prototyp for a new kind of high composite content airframe, wings arrangement and pilot/jet interface and actual Rafale. The external look may seems the same, but not a single shape is the same.
Between Rafale A and serial Rafale there are the same kinds of difference than between B1 and B2, or between YF17 and FA18.
Interesting to see J20 small non aligned canards for a so called 5th gen fighter....
I have a question, how do you eliminate the radar wave emitted by the airframe, you can deceive it by analyzing the Chinese radar, but the radar wave reflected by the airframe is like a bonfire in the dark night telling me where you are
There is a joke in China that after the 2019 air war, both Pakistan and India are looking for longer range missiles, as if range is everything
Clearly this is not a scientific method of calculation
We have taken your second photo as an example
You can see the huge boundary layer divider between the intake and the body, it's an obvious cavity, you can think of it as a giant corner reflector with a non-negligible effect on the RCS
third picture
You can see a lot of air intakes, this is the natural Lumbo lens, for the Rafale, it's like wearing shiny clothes in the dark
First of all, stealth is systematic engineering, not simple arithmetic. As I said before, a small bulge on the fuselage and the interaction of the fuselage can seriously damage the stealth effect of the aircraft
The first airborne AESA of mankind should be the APG77 on the F22. It is already after 2010 that Europe has entered the AESA era.
Not only fighter jets can find Rafale fighters, ground radar, early warning aircraft can also find him,
The small RCS value of the missile has little effect, and it is also wrong. A large number of irregular scattering will form between the missile and the body, and the RCS value they generate is even larger than that of the aircraft itself.
And the premise of your assumption is that the gust can fire all missiles at the maximum range of the missile, but the fact is that the fighter will launch a missile at the maximum range of the missile, forcing the enemy to lower the altitude, get yourself a better position, and then Missile launch in no-escape zone
Generally speaking, the maximum range of the Meteor missile is 180KM, and the no-escape zone is about 80KM.
The J10C has also adopted a number of measures to reduce the RCS value, such as the use of DSI intake ports,
Bury a large number of protruding air inlets to make the body more smooth,
At the same time use metal coating on the cockpit to reduce RCS
I really do feel that in the Absence of More Rafales ,IAF will rely on large number of ALCM Brahmos ; And NG -- ARM for knocking out Enemy SAMs ie against Pakistan
And also use Surface to Surface Missiles like Pralay ,Prahar etc
The most important and Time Critical task will be taking out SAMs
When enemy SAMs are destroyed , the Need for Rafales is over , then Rafales can concentrate on China and Su 30s can take on the PAF
The Saudis have bought your b-600's so it's not that surprising Arab countries have more influence on the policies of the west rather than they reverse. They are slaves to the Semitic people so it's not that surprising.
I don’t know what you are talking about. Semites are a very old concept. Saudi Arabia is facing the threat of large drones, cruise missiles and cruise missiles. Chinese products can meet their needs. That’s enough.
Lesser range compared to comparable aesa's very high mtbf. Atleast for the export versions. I assume the Chinese deliberately export monkey model products like what the russians & USSR did because looking at the pl-15E and klj-7 aesa they seem pretty average unlike the dumb westerners who hype whatever you guys do to expand their own MIC.
The standard is different. For example, the search range of the radar is different at different altitudes and different modes. The same is true for the PL15E. Sometimes you are not comparing the same thing at all.
Of course, we will cut some sensitive technologies, such as the composite seeker of PL15, and the electronic warfare mode of AESA will also be modified to some extent
Yeah I'm judging your stuff through your export models. I've rarely seen any decent literature on your contemporary weapons. So all conclusions come from whatever weapons the international media covers and open source. From that most Chinese exports have had a pretty mediocre performance.
The radar wave emitted by the airframe creates a radar signature, active cancellation removes that signature. In some cases, the signature can be entirely removed, or the signature is so small that it's considered to be dust, water vapour etc, ie clutter, and is rejected.
This process is called destructive interference.
India has been looking for new options since early 2010s. For the MKI, the choice was between Derby ER and Meteor. Now Indian options have come up. Pakistan had no options due to the unofficial arms embargo from the West, so they seem to have been waiting for China to give them some.
Anyway, India did not have long range options until 2017. Europe denied Meteor for Russian jets while Derby ER was still in development until 2017. But the MoD and IAF have been slow in making their choice. It's just bad luck for us that we didn't enter the fight with Derby ER or Meteor (our main preference).
It is. As long as the numbers are accurate. RCS is additive.
You can't eyeball stealth. You have to measure it.
Incorrect. Stealth is simple arithmetic. System design is not.
The first airborne AESA for fighters is APG-63(V)2, introduced in 2000. Followed by Japan's J/APG-1 in 2002 for the F-2, followed by UAE's F-16 B60 with APG-80 in 2004. Then came the F-22's APG-77 in 2005.
The ASRAAM's RCS is said to be 0.001m2 class. Anything with an irregular shape has irregular scattering, but the question is how much of it goes back to the source. This can only be measured in an anechoic chamber.
I never said anything about maximum range. Everything else is defined by tactics. It has nothing to do with RCS.
Yes, we are introducing RCS reduction in later blocks. We are doing what the French accomplished in the 80s. It doesn't change the fact that our jets are behind the Rafale by a significant margin.
Look at TEDBF, it incorporates all the main features of Rafale and refines it further. It's obviously gonna have a much lower frontal RCS than Rafale.
So you will have to demonstrate lessons learned on new designs, like the J-20 and J-31. But what it means is the J-10 is way behind the Rafale's design. PLAAF needs J-20 to defeat the Rafale, not J-10.
The Rafale is necessary from the start to the end of the conflict. As time passes and the enemy becomes more advanced, we will need greater numbers of Rafale to keep up.
You can also assume that enemy SAMs can survive throughout the duration of the war too. At least that will be the case for China.
Lack of combat experience, like the TB2, he is pretty much the worst drone you can find on the market, but due to the Armenia-Azerbaijan war,
many people buy them
