What happened on 13 May 2023 was very intrigued.That day as we know in the Russian air space ( over Bryansk area) were shot down one Su-34 and one Su-35S. All three crew members were KIA.Some serious Russian sources ( from TG channels) mentioned that Ukrainians used MIM-104 with newer AN/APQ-65A with its LPI signals (very high frequency agility).Sources also mentioned that they flew in the radio-silence mode and even with no RWR activated.



Some open sources mention that LPI radar signals ( using a technique called 'spread spectrum transmission') can not be registered by any RWR, hm,hm ...
There is no such thing as AN/APQ-65. You have instead a AN/APG-65 radar which is installed on old F-18 Hornets, and you have the AN/MPQ-65 which is a radar used for the Patriot missile system, replacement for the older AN-MPQ-53 radar. The version AN/MPQ-65A is a newer version which was presented in 2017, with AESA antenna array and improved beam and frequency agility, but it was not confirmed to be present in Ukraine.

What is specific for the Patriot is the track-via-missile system. A receiver for the reflected signal is placed on the missile and thus has increased accuracy as it approaches the target. Instead of processing it locally, the signal is instead rebroadcast on another frequency and received by the launcher. The launcher then compares the signal it sent to the one received by the missile, and through this comparison can perform the determination of the target location relative to the missile. But because the ground station knows the rough location of the target, and details of the original signal it sent, it does not require the signal to be continual and thus does not demand a separate illumination radar. So it is hard both to know that a missile is coming at you and also to jam the missile.

Of course AN/MPQ-65A ,little mistake. TVM technique is used also by the SAM-10 e.g. and even by the new AAM type R-37M.

I'm kinda curious about this, is Track via missile on Patriot basically the same thing as 2 way data link on AIM-120D

What is ''two way data-link'' in fact ?

RWR would aways be active since it doesn't affect your radio silent capability because it doesn't transmit anything

Yes if it is activated of course.... RWR/ESM is based on the passive radio-location as we know.

In a two-way data link both the launching station or aircraft talk one with another. In a one-way data link only the launcher talks with the missile. For example, in previous versions of AIM-120 AMRAAM up to the C variant the firing aircraft continues to track the target, periodic updates, e.g. changes in the target's direction and speed, are sent from the launch aircraft to the missile, allowing the missile to adjust its course so that it is able to close to a self-homing distance where it will be close enough to "catch" the target aircraft when the missile activates its own radar.

For the AIM-120D mid-course updates are transmitted to the missile over a networked data link system and any system with sensor contact on the target can contribute track data to the missile. This means the launching aircraft, another aircraft in the same flight, an airborne early warning aircraft, or a ship are all equally capable of providing mid-course updates at any time during flight. For this the missile should be able to "talk back" to these suppliers of data, so that they know to which the missile listens.

RWR/ESM like all ECM must be activated (turned on) .

'One way data link' is so called RC-channel ( radio-correction channel) or 'mid course update' as it is known in the western terminology. So called 'two way data link ' e.g. had MiG-31 even from 1980 in the combat mode known as 'Tandem' where one or more interceptors fly in the radio-silence mode and only one in the patrol group has its radar turned on in the IZL mode. His radar than can track the given targets and can send RC channel signals to the launched AAM's. There is of course new 'TVM channel' and keep in mind that all RC channel signals work in the centimetric X band so that story about AWACS can provide 'mid course update' for the launched AAM's are nothing than joke. AWACS radars work in the decimetric L band or centimetric S band together with decimetric L band for the IFF.

Btw , AAM's can not send any kind of signals to the own launch platform or another one.

Note : R-37M which can be launched from the MiG-31BM,Su-30SM2 or Su-35S can receive RC-channel signals from max 100km from the aircraft's radar ( either from the launch platform or another flying in the same combat group). Before every combat mission ,every AAM like R-37M must be 'paired' ( so called LITER codes and programmes) with the radar of the own launch platform- fighter/interceptor or other ones in the same combat group.RC/TVM channel signals work in the specific frequency spectrum ( centimetric X band) and are sent through the sidelobe.

AWACS can provide updates for AAM or SAMs. It not the radar, but a networked link called NIFC-CA.

it connects fighters, AWACS and warships together. The Sukhoi family would need to obtain a similar capability if they want to remain relevant.

I’m glad to see these old gals still flying. Always the prettiest of the Flankers in my opinion. These and the original Su-35/Su-27M, single seat and Canards was peak aesthetics.

EDIT: To clarify since my post was edited by the mods for quoting an earlier post in this thread, I was referring to the Su-33s posted by Squirrel

It seems that 6th batch had two or even three new Su-35S. Interview with one of the VKS fighter-pilots ...

Although it is nice photo but I must mention my personal opinion.For me it is more important to have such a capable and modern fighter like the Su-35S in the front line combat( or first-line) VKS units than in the one aerobatic team.Especially when we talk about the fighter with so capable radar ,AAM's and engines with TVC nozzles.

When we count all of that Su-35S ,from the 'Russian Knights' (8pcs) ,then those in Akhtubinsk ,Lipetsk and Zhukovsky air bases ,there would be enough fighters for one complete fighter sqn (12 pcs ) ,maybe not for the complete regiment. Of course ,Su-35S must be stationed in the Lipetsk air base (4th CBP i PLS) but for me it is very important to have such a capable fighter in the units like 689 GvIAP in the Chkalovsk air base in the Kaliningrad Oblast or 38 IAP in the Belbek air base on Krimea.

I suppose that they are filling operational units with the new fighters, i.e. fighter regiments located along the western borders ,close to NATO countries, because just last year and until now with this sixth delivery, close to 30 new Su-35S were delivered to the VKS ( 16 last year in the four batches and until today complete sqn or more).
 
Plenty of Su-57, Su-35 and Su-34 deliveries, very little Su-30s. I presume the type has fallen out of favor with the VKS?
Well, the VMF still need probably a few dozens Su-30SM2s to replace the remaining Su-24 and if they really take Kuznetsov out of service, the old Su-33s too. Plus there are i think still export orders to complete (Belarus? Kazakhstan? others?) but i guess it's another subject. But yeah i would be disappointed if VKS doesn't take another few dozens Su-30SM2s over the immediate period, they need numbers and SM2 is still a capable bird especially with R-37M and hopefully R-77M/R-74M2 too.

I can't say i entirely disagree with this argument at least for RK, probably was better to just use some Su-27SMs/Su-30/30M2s instead, though i guess acro-groups are about showing the flag and all that. But i do see the need for conversion/training units to have them, afterall the pilots need to be exposed and train with the new birds first, can't argue with that.

They don't offer much of an advantage over Su-35S though

There was a contract for the 21 new Su-30SM2,maybe that contract is fulfilled ?

Su-34 is the most used type, which has its niche. As bad as the type is, it's hard to displace it in current context.
Su-35 is by far the most capable type, with significantly better...everything basically. Yes, parts of equipment are already getting dated, but it's just a far more capable package.

Su-30sm(2) family is ultiimately a dated type(25 yrs old), with demonstratedly worse survivability, high rcs and relatively low airframe hours doesn't stand out well.
Yes, SM2 got updates across the spectrum, but by and large it's a vanilla hornet v superhornet type of relationship. Updates brought what was already here up to speed, didn't change the nature of the aircraft; at the same time, they probably brought cost up, too.

I.e. for naval aviation or major users of the type(Indians, for instance), it makes sense. For VKS - not really.
 
When we talk about the fighters/bombers in the operational units: VKS and MA VMF has more than 150 operational Su-30SM/SM2/M2, VKS has more than 200 Su-34/M and about 150 Su-35S.
 
VKS has more than 200 Su-34/M
200 have been produced, FB recently dedicated a post to the fact, but not all of these are VKS aircraft and not all of the produced aircraft are still flying due to airframe losses from accidents and opposing (and sometimes their own) AD systems in the war in Ukraine.

I checked again,until 2020 NAZ produced about 130 Su-34. Almost 80 new Su-34M/NVO will be produced until the end of 2027 under the contract from 2020.

Question, is there about 150 of them operational because about 30 were lost from Feb 2022 by the Ukr and Russ AD SAM's ,by the drones and there was also non-combat losses.

"FB", you mean that «Z-блогер» Russian Telegram user "Fighterbomber" ? Well, if you take such things as reliable information, I understand better...

Well, while i can see VKS's affinity for the Su-34, and while it is an impressive bird by all accounts, if there is one VKS type that i'd have replaced with something else is the Su-34. A Su-30SM with a pod could fundamentally do 80-90% of what Su-34 is doing imo, and the main reason for such a substitution would be the gross numerical inferiority of VKS vs NATO, VKS need any fighter they can get. The Su-34 is too optimized for the attack role, and doesn't seem to offer sufficient air to air capability, while the Su-30SM2 with R-37M is a very potent bird still.

Hell i would have had MiG-35s instead of Su-34, say 300 MiGs instead 200 Su-34s, to further help alleviate that numerical fighter disparity, though i guess i'm too biased for the MiG. More MiGs mean more sorties, yes they don't carry as much and don't have the range of su-34, but then aircraft with shorter range like Su-25 seem to operate quite well over the frontline, so workarounds could have been found.

That's just a personal what-might-have-been though, the Su-34 is here to stay and will likely do so for decades to come.
 
Btw....

Su-34/M is the carrier of the heaviest bomb in the VKS, of course FAB-3000M54 with the UMPK.


Su-34/M can carry tactical cruise missile type Kh-36.


Su-34/M is very maneuverable tactical bomber.

One article:

Longer Range, Heavier Payload, Larger Production Scale: How the Su-34 Strike Fighter Became the Backbone of the Russian Fleet​




Su-34 is simply the workhorse of the VKS.
 
This is 'FFF' thread ....

Yes,Su-34's as modern and capable frontal/tactical bomber were downed by S-300PS,Buk-M1,MIM-104 etc .It happens ,shit happens as 'FB' ( former Su-24/34 pilot) described once. Nothing new, USAF super modern tactical bomber F-15E was shot down in 1991 by then 30 years old S-75 Dvina .In 1999 as we know, modern and very capable stealth tactical bomber F-117A was shot down by 25 years old S-125M Neva-M.There is no combat aircraft that can not be shot down. There will be always a battle between SAM's and the fighters/ bombers.

So refreshing to read something sensible at last.
 
What??? You do realize that none of the aircraft you mentioned can strike anything in the rear of any nation with a half decent IADS network, right? Do we seriously have to go through how Saudi F-15s and other Arab coalition F-16s were shot down by some of the least sophisticated air defense systems the Houthis brought to bear in Yemen?
As per fighterbomber, su-34 can't do automatic terrain following and can't do obstacle detection; features removed in 2000s to save on costs. As such, su-34 can't do very low altitude flight in adverse visual conditions, over populated area it can do low altitude (several hundred m), to be safely away from power lines and microterrain.

It's self defense suit is known to be ineffective, blind and undertested (problems with aircraft happily jamming each other, and that coming as a surprise to the crews), i.e. bad even at that it can do. It's also quite incomplete, compared to su-35s or other modern aircraft; as a result, by large, Su-35s pilots have to control evasion by Su-34 crews.

It also leads to a major poassible conclusion - entire escort jamming capability of VKS right now is dead, as it's reliant on Su-34 sensor package (ironically, Algerian quite likely won't be dead, and powerful jammers will work as intended). Extended jamming pods can't jam something they don't even know. This further decreases chances of succesful attacks against contested targets.

I.e. just from that alone, its penetration capability is below any modern fighter bomber, including su-24m. Which does have this capability from 1970s.

Penetrating 1980s level air defenses was done since 1991, and defenses as of feb. 2022 were absolutely 1980s level defenses. Literally model Fulda gap threat. Last time it was done half a year ago, in Iran - which weren't really 1980s level defenses, as Iran had significant number of PESA/AESA systems.
If you seriously believe that this is the role of a tactical bomber
It isn't a matter of belief. Please refer to description from OEM. This is basic, i.e. your arrogance is suprisingly uninformed.
If i can help you with something else, please ask.
Ukrainian AD is dismantled far more effectively and with less risk through Iskander-M and Tornado-S
Criteria of succesful dismantling AD is freedom of achieving missions.

Fires indeed are a part of SEAD/DEAD fires plan and overall effort. Nonetheless, ground fires in general, and Iskander nor Tornado-S aren't particularly decisive at "dismantling far more effectively with less risk". Even HIMARS with all western space assets failed to achieve that. There are, to this day, limitations at how well these types of weapons can prosecute mobile targets and evaluate results of attack - which is absolutely paramount for SEAD. They're also reliant on kill chain.
The only reliable way to DEAD, to this day, is stand in reconnassance/strike capability with sufficient detection and ability to immediately prosecute detected targets. There are two traditional ways to do that reliably - stand in aircraft, ground operations. Now (a new one) there's also drone overwatch.
Let me guess, you believe that flying low and slow with sweepy swoopy wings does the trick, right? Lol
Yes, that's the way it's done by non-lo aircraft; furthermore, Su-34 was, by large, an update to basic flanker airframe to let it do viable low altitude flight. As you may have noticed that Su-34s early in the war did exactly that. And this is exactly what it turned out it can't do.

Regardless of how outdated this method was - they were bad at it. If you say it doesn't matter - beg to differ; at average of less than 1 airframe lost per day early in the war, during initial high tempo ops (high readiness - let's, for example, assume 100 airframes; several sorties per day, let's take average of 2) we rather easily come to likely Su-34 loss rate of below 1 per 200 sorties.

Add in actual low altitude flight, fully working self(and collective) defense suit, effective last ditch defenses, and remove need of direct target overflight at night (replace high drag bombs with basically any modern JDAM kit) - and this 200 will probably quite easily fall by order of magnitude. Which is, say, 2000.

Still not ideal and not sustainable long term. But enough to sustain heavy bombing compaign of opfor deep rear for many months, rather than a couple of weeks.
Then let's teach our bombers prosecuting targets of opportunity - things like maneuvering columns(including AA). And now these months matter.

P.s. hopefully it's on topic enough(su-34 technical discussion). If now, absolutely welcome to delete post.
