This Su-35 capability based on Ukrainian data.
As the UNIAN correspondent reports, Reznikov announced this at a joint briefing with Croatian Defense Minister Mario Banožić in Odesa, commenting on foreign media reports that Ukraine will receive these planes and Ukrainian military personnel are allegedly already learning to fly them.
Reznikov noted that he is very grateful to the French mass media that support Ukraine, but the information does not correspond to reality.
"I would like to give a technical understanding. Today, the Air Force of the Armed Forces of Ukraine has a MiG-29 fighter that can "see" with radar at a distance of 60 km and hit air targets at a distance of 30 km. The enemy on the Su-35 "sees" more than at 200 km, and it can hit air targets at a distance of more than 140 km. The Mirage 2000 has the same performance as the MiG 29...," said Reznikov.
He emphasized that the Armed Forces would be grateful for any aircraft, but the main combat aircraft should be more modern. That is, it should "see" more than 200 km and hit targets at a distance of more than 150 km.
"The main combat aircraft is, first of all, a part of our air defense, this is postulate No. 1. Because this is exactly the element that we still lack in order to consider that the air defense system has been created effectively enough," said the Minister of Defense of Ukraine .
That's realistic assumption. Ideally the Su-35 can "see" 3 sqm at 350-400 km. If we take 400 km, and 50% probability of detection with False alarm time of 10^-6 which correspond to a Swerling 1 target, it correspond to signal strength or SNR of 13-15 dB.
In order to lock on and continuously track the target with good certatinty which correspond to probability of detection of 90% or higher it is therefore correspond to SNR of 24 dB. But then those are assumption based on a single pulse detection, multiple pulses integrations will decrease that value. Maybe down to say 11 dB for 50% PD and 17 to 90%.
Regardless of what value of SNR used. One then can calculate the "lock on range" based on the SNR value using the 4th root "radar reference range" equation outlined in George M Siouris's "Radar Performance Modelling 2nd Edition". just make sure to convert to linear from dB. Basically like this :
R90=R50*(SNR50/SNR90)^(1/4)
R90 is lock on range or detection range at PD 90%, R50 is the same except its 50%
SNR90 is SNR or Do (Detectability Factor) needed to achieve 90% PD or confidence that the contact that appear is really a target instead of false alarm and so does 50%.
IF we take R50 of Irbis as 400 km.. then the "lock on" range would be :
R90=(12.58/50.11)^(1/4)*400
R90=280 km
If we take R50 as 350 km then the Irbis would "lock" that target at 247 km.
Which well within the envelope of R-37's
Applying that for Bars R indicates range of 176-212 km (250-300 km detection range) Which i think explain why there is Su-30SM2 with Irbis.
------------
For Ukrainian options however such detection and engagement range indicate they desire some top class of Western fighters, in class of Typhoon, Rafale, Gripen or F-15C's. Three former is probably more desirable as it can natively fire Meteor which can offset or offer parity to the R-37M's as well as threaten Russian AEW in its entire operating theatre.
Something smaller as Viper might not be really desireable from BVR perspective but can be included as frontline fighters hunting Su-25's or Russian attack helicopters.

The Russian combat robot "marker" will be equipped with Four Kornet anti-tank missiles
they intend to quickly launch the robot in series for use in the NWO region.
The former head of Roscosmos Dmitry Rogozin previously posted a video with Marker on social networks. He noted that the equipment is being tested, and for the first time four anti-tank systems were installed simultaneously on the Rotary support unit of the robot.

I'm curious Russians haven't yet put any interest on fire and forget ATGM's. Despite possible increase in cost, having a missile not needing constant illumination from launcher platform is an advantage, as it allows the gunner to engage multiple target simultaneously or quickly evacuate from firing position.
The market are now have China's HJ-12, Korean Raybolt and French MMP

Product-305 is fire and forget, but it is expensive and only has been in service for 4 years, there is some concepts of adapting it to be used in Sturm like vehicles.I'm curious Russians haven't yet put any interest on fire and forget ATGM's.

If russians are able to upgrade their bad IC industry we could see it in the future...
The Russian channel "Fighter Bomber", which was the first to announce and publish a picture of the now famous Russian "JDAM" kit, said today that Russia can produce several hundred of these kits a day if necessary.
More interestingly the Russian "JDAM" kit, the UMPC (Unified Planning and Correction Module), now has a version already accepted in service for the FAB-1500.

Russia have long training of MIG-31 shooting down cruise missiles and if R-77 class missile could do it there wont be any need of R-37. which they consider hypersonic all fight. The last i read in arabic rt was burn time upto 180 second. F-35 class target at 190km. These attack choppers and Su-25 fly even lower than cruise missiles. they can theoretically threaten it but at very short distance.For Ukrainian options however such detection and engagement range indicate they desire some top class of Western fighters, in class of Typhoon, Rafale, Gripen or F-15C's.

what is Meteor range against low flying object?
This is kind of pointless. They are better off on such missions with a vehicle like Khrizantema-S.The Russian combat robot "marker" will be equipped with Four Kornet anti-tank missiles
they intend to quickly launch the robot in series for use in the NWO region.
The Khrizantema-S can outrange any infantry ATGM squad or tank.
Where the robots would make sense, I think, is city assault, and for that what you need is a robot with 360 degree vision, thermal sight, automatic target classification, and a 30 or 57 mm gun. Not Kornet.
