Wanted it to look like dual mount stinger setup rather than this mistral like setup, DMS setup looks more lighter and compact to my noob eyes

A system can either be man-portable (like Igla) or non-man-portable (like say RBS70); there is no point in putting efforts in lightening a non-man-portable system if even after lightening the weight is still too much to become man-portable.

As soon as you make it a tripod system the whole weight thing becomes irrelevant

VSHORAD twin-launcher setup:

And now we just wait for Sanharika to achieve its maximum potential

Top it off with some lightweight radar like Ashlesha and you'd get a teeny tiny yet quite a formidable platform for the Himalayan sectors.

Bhim is still possible. We already have the chassis of Arjun MK1A.

Now sell this to the el generals who already have ready access to K-9s. They will immodestly cite the weight increase from Arjun's chassis. Let ATHOS in, and ATAGS will suffer the same fate.

Aero India 2023: Indian Army orders QRSAM weapon systems

The Indian Army has ordered five Quick Reaction Surface-to-Air Missile (QRSAM) weapon systems, manufacturer Bharat Electronics Limited (BEL) told Janes at the Aero India...

Qrsam ordered by army ?

IDK where to put this generic question:
Can an EW jet like EA-18G be totally immune to AAM/SAM? If equipped with antennas of multiple band used by missiles, then can it jam & deviate any # of missiles fired together at it?

Short answer; nothing can be made absolutely immune.

Now the long answer

If we talk about EW jets or even SEAD/DEAD jets then we don't have a diverse dataset (multiple countries Vs multiple countries) to look at as USA is pretty much the only country to seriously work on these over the decades. If USA is the only...obviously Russia would have been the only country worried about these EW jets. So what were they doing? They were modifying their existing AAMs for Passive Radar Homing. Both of their mainstay BVR-AAMs have a PRH variant; R-27P and R-77P. You take any other example of BVR-AAMs like AIM-7, AIM-120, Super 530 you'd find that at some point everyone had tried making a PHR variant but none got adopted except for the Russian ones, as only they needed to counter USAF EW platforms.

So if an AAM is fired with an PRH seeker and advanced features like home-on-jam then it can very easily pose a threat to dedicate EW platforms. Not to mention the fact that a PRH missile won't trigger the Missile Approch Warning System the way an Active Radar Missile would, further narrowing the window for the pilot to take evasive measures.

Also i belive Russians usually fire R27 passive/active homing missile along with R27 IR homing missile to increase chances of hit.

Absolutely correct, when R-77s were not there and R-27s were the premium AAM then it was a common tactic to compensate the lower kill probability of single missile.

Incidentally R-27 would be one of just couple of missiles with which one can use this tactic as it was virtually the exact same missile with the only difference being the seekers across RF and IR variants. You can't do this with say AIM-9 and AIM-120 as both would have completely different kinematic profiles.

The only modern analogue I can think of would be MBDA's MICA. It's also the exact same missile with interchangeable seeker heads that make it either MICA-RF or MICA-IR. Tough I've this gut feeling that the next generation of BVR-AAMs would combine Active, Passive Radar Homing and IIR into a single seeker.

Bingo I had same desire and inkling that as minitiaurisation progresses we shall see sensor fusion. I also have an idea if its feasible to build to long range x band radar which can be slapped on Awac wide body which while flying in safe zones can share data with CAP crafts who can launch missile on basis of shared data without engaging own radar. X band radar can continue to guide those missiles to target. Same X vand awacs radar can fire really long range AAM to take down or even bog down planes in enemy airspace. But again its part of my sunday musings.

Truth is we don't really know... In theory yes.

We might even find that stealth jets might turn out to be duds in practice if BVR missiles are too vulnerable to EW. Yet to be seen.

I'm limiting focus only to RF system, not IR.
I understand it is always a Tom & Jerry game on both sides - staying undetected but detect enemy, AESA, PESA, narrow beam control, frequency hopping, active cancellation, 1st look, 1st shot, 1st kill, etc, using mix of passive & active techniques.
CT/IT guys don't study electronics deeply like the specs of electronic parts, but AFAIK the trancievers have certain sensitivity level beyond which people say that it will get "fried" bcoz the EM wave is converted to electric signals for processing. IDK if the radome has some kind of filter to limit the strength of radiation like our polarized goggles do in the visible spectrum, but that would be disadvantageous to PRH seeker.
These pods, including the wingtip ones, exist bcoz a fighter jet's EW suite is not enough, different band antennas have different size. In case of stealth jet it becomes a bigger challenge.
To counter home-on-jamming, a towed decoy is used & their makers advertise proudly.
IDK if LASER can be used in DIRCM then if MASER/RASER can be used in DRFCM or not.
But I'm not talking about DEW advertised for 6gen jets, with its own conditions & challenges.
Even if an ARH-AAM use frequency hopping or a PRH-AAM tries home-on-jammer,

Ultimately i wanna know if a pod based EW system can FRY the RF tranciever of incoming missile, just disorient, break lock & deviate it somehow ALWAYS.

I wonder if USA or Russia has tried this combo of AWACS+VLR-AAM/SAM.
