One must add super also name to this thread, so no dual creation on sukhois will be there.
That Is Why Said It Used With combo of ARH And IRThere are 2 issues with this:
1- for a total passive shot, as in you don't turn on your radar. The attack range will be limited by the laser finder range of OLS irst system, which is often about 15-20 km.
2- R-27ET and R-27T are lock on before launch missile without mid course radio correction. The missile must lock onto target while it is still carried on the launcher. If even OLS-35 won't detect head on target from distance further than 35 km, there isn't much chance for R-27 infared seeker to do such a thing. R-27T and R-27ET are intended to be used as tail chase weapon against target that R-73 unable to reach.
HAL is offering an indigenous AESA radar for the MKI upgrade. It's unclear if it's referring to Uttam or 2052 or other AESA

.
they lock on to emitting signals of radars/ communication radios etc
Can someone tell me how anti radiation missile works against SAM system in basic words?.
Most probably UTTAM with GaN TR modules
Firstly, there are no R-27EA or R-27EM beyond the paper stage, they were only at the potential concept stage and never went further than that.That Is Why Said It Used With combo of ARH And IR
R-27EA And R-27ET are Combo weapons
ET Version has good Extended Head on range of 52 km Unlike previous R-27T version which was 2 to 33 km head-on
Also R-27 has (LOAL) capabilities

Firstly, there are no R-27EA or R-27EM beyond the paper stage, they were only at the potential concept stage and never went further than that.
Secondly, only the SARH seeker of R-27ER and R-27R have lock on after launch mode and mid course guidance
R-27T and R-27ET (R-27 version with IR seeker) doesn't have lock on after launch and datalink
Some infrared guided missile such as AIM-132, MICA can have LOAL mode because their infrared seekers are FPAs, so they can visually see the 2D picture of target, and they can choose target based on pre-loaded images in their library
R-27T uses 36T IR seeker (same as the one used on R-60M) and R-27ET used MK-80M IR seeker (same as the one used on R-73. Both of those seekers are mono block recticle infrared seeker, they need to be locked on target before launch because they only see the target as a point source.

R-27 ET Is not On concept stage But DemonstratedFirstly, there are no R-27EA or R-27EM beyond the paper stage, they were only at the potential concept stage and never went further than that.
You should read carefully what version of R-27 which I said are paper projectR-27 ET Is not On concept stage But Demonstrated
R-27EA, active radar homing with 9B-1103K active seeker, range of >130 km

Not sure what you are trying to prove with this photo?the MWIR two colour high off-boresight gimballed MK-80M series scanning seekers use a Magnesium Fluoride window (Military Parade).

No, you don't need a dedicated EW aircraft and to fool a fighter with AESA radar and you don't need to detonate a nuclear bomb in space to blind ground based AESA radarAESA radar, with AESA radar you can virtually escape from all type of aerial threats. Only a dedicated EW attack aircraft will ablebto fool a fighter with aesa radar. And against ground based aesa radar, you need to detonate a nuclear bomb in space to blind it.
No, you cannot. AESA radar used to produce multiple frequency. The only way to fool aesa is to generate a white noise comprises the all those frequency. Problem with that type of jamming is that, the jammer attached to your jamming pods cannot produce sufficient powerful white noise. You need dedicated EW aircrafts.
Spectra works on active cancellation or destructive interference. You need to fix the frequency fir that technique. Spectra works well with pesa or dopler radars not against aesa radar.
Thats why american sees s400 as atgreat, the aesa radar of s400 cannot be jammed even with present day growlers.
R-77 Is In Production as Per TMJC. Just like ramjet R-77, KS-172 and many others mock up that came before and after it.
I posted That Picture To explain You how Guidance Work With MissileI know how missile with IIR seeker and datalink work.
That picture however is not the working principle of either R-27T or R-27ET, it is a photo taken from the infamous Airpower Australia site, where the author depicts a hypothetical 2 stages missile (which is kinda stupid because if I remember correctly, he just merged a R-74 and R-27 together.

Firstly, the missile in that link is RVV-BD which is supposed to be a modernized version of R-37 on Mig-31, it got no relation to R-77 whatsoever (it should be quite obvious as well since RVV-BD is 500 kg while R-77 is about 190 kg)R-77 Is In Production as Per TMJC

I certainly don't need you to explain how Guidance Work With Missile. And no, not all missile active their sensor at the terminal phase. Most infrared guided missiles, especially spin reticle IR missiles must locked on target before they are launched.I posted That Picture To explain You how Guidance Work With Missile
All Missile's Weather it Aim-120 or R77 or R-27 Employs Active radar Seekers At terminal Stage
Before that they have two stage guidance mode Same goes For R-27 ET
Its Employs Its IR seeker When It Reaches at Terminal Stage Near 40-50 km depends on Altitude
In control system of all missiles, in addition to seeker, an inertial navigation system with radio-correction is included.
The R-27T1 and R-27ET1 medium-range air-to-air missiles with IR homing heads are designed to engage various air targets, such as highly manoeuvrable aircraft, helicopters and the like, in the front and rear hemispheres, by day and night, in spite of natural and organazed jamming, in compliance with the "fire-and-forget" principle.
The missile guidance system employs an updated proportional navigation method with the target lock-on accomplished on the suspension under the carrier.

The missiles' fusing systems are based on radar proximity and impact target sensors.

Did I say India technology is bad? No.Since You Talking About FPA Technology I Don't Know About Russians But India Is At very Advanced Stage of FPA Technology Here Research Paper By IIT Bombay
That Why Most Of those IIR missiles are CCM 's Like R-73E And Aim-9xAnd no, not all missile active their sensor at the terminal phase. Most infrared guided missiles, especially spin reticle IR missiles must locked on target before they are launched.
Yes I know What I quoted Since Yourself Don't Under Stand the PrincipleI mean do you even pay attention to the source you have just quoted? do you even understand what is " target lock-on accomplished on the suspension under the carrier. "?
R27 range and internal electronics are much better compared to older R77.Curious, is R27 better than R77?
Or you are basing this notion upon IAF's recent bulk buying choice of R27?
I think these ranges are for ideal straight glide paths. If you are subduing the missile to increase its AoA, these ranges become less effective.R-27 ER- Semi-active radar homing- max range: 117km
R-27 ET- IR homing- max range: 104km
R-27 EA- Active seeker- max range: >130km
R-27 EM- Active seeker- max range: >170km
Must be the integration issue with Radar and onboard fire solution computer?R-27 is q
We ordered R-27 ER1 and ET1 variants after the Balakot episode.
Wonder why we did not procure EA and EM variants considering they have significantly longer ranges.
Firstly, the seeker of R-73E and AIM-9X are not the same, R-73E use MK-80M which is a spinning reticle seeker. Whereas AIM-9X use a FPA seeker. In other words, R-73 is an infrared missile (IR) while the AIM-9X is an imaging infrared (IIR) missile.That Why Most Of those IIR missiles are CCM 's Like R-73E And Aim-9x
Very simple because R-27T and R-27ET are not supposed to be launch at 100 km.Yes I know What I quoted Since Yourself Don't Under Stand the Principle
Kinematic Range R-27 ET Is 120 km While IR seeker It Carries Only has detection Of 14 Km at terminal stage Same Way a Active Radar Seekers Works
How do you think Missile Will Launched at range 100 km When active seeker just has Acquisition range of Max 20-25 km For whether Its R-77 Or Aim-120 D It uses Data link Via AWACS Or pe-loaded Inertial Navigation
That Why I said most BVRAAM have Two stage guidance mode
Inertial For Launch And cover distance of Kinematic range While Second Guidance At terminal stage
No, it is because R-27EA and EM were never produced, they are paper project just like R-77M and KS-172Must be the integration issue with Radar and onboard fire solution computer?
