Now this is something you cannot possibly find a reliable answer to in a defence forum 😅
no one is talking about them despite their advantage everybody is just running towards conformal antenne gripen e cover 190 angular coverage typhoon covers around 180degree but rafale has no swashplate hence covers 140 only

No, my bad... Was replying to multiple people.

As of now AMCA Mark1 probably (so let's not get into that) isn't meant for WVR dogfigh. If so, then the absence supermaneuverability won't matter much.
Supercruise would be good to have though, but the platform really looks crazy good aerodynamically (which also has got some people complaining about the rear visibility)!.. I won't be surprised if it can hold supersonic speed in internal-only config after an acceleration with afterburner.
Watch this aero India 2021 interview the lady clearly states that amca will be supercruise capable!

ok first of all how did rafale ,iaf and hangers come into context can u explain?
air conditioned hangers for f35.
F35 need new hangers like rafale.
Unwanted comments. Even 4.5 gen need hanger suitable for it except for jas39. Hangers is a issue to IAF.
What do you think, f22/b2/su57 don't need hanger like f35.

ok now last comment on this topic f35 needs special care, stealth coatings are delicate
by new hangers i meant specialised ones not ordinary new ones like any other ones

Just look at the cruising capability of fa 18 weighing 29 tons whereas amca is 25 tons and will use same engine.
No no, you're taking about MTOW load. That configuration has huge additional drag from the payload. Supercruise is done in clean (external) config, with only internal weapons.
Plus it ain't just engine thrust... The AMCA is far far more aerodynamic than F-18 (famous for "losing energy the quickest & gaining the slowest" among all USAF fighter fleet).

The latest version has bulged out the section behind the cockpit canopy like MWF to achieve superior area-ruling compared to the previous iteration.

Yes even I’m surprised that an aircraft specialist country Russia was unable to make a true 5th gen aircraft, it also doesn’t have an internal weapons bay, it lacks a serpentine intake, it lacks DSI, it‘s Avionics are 4+ gen etc, Chinese 5th gen aircrafts are non-stealthy, J-20 can’t carry a Close Quarter Combat Autocannon and it doesn’t have a proper engine right now.
No it has a IWB.

it can be for amca mk1 or amca mk2 because two iterations were planned earlier and 2nd one(amca mk2) was to hve supercruise ability
If Rafale with 2 m88 can supercruise with 4 external bvrs then Amca MK1 with 2 ge f414,own,polished design will be capable enough

How is it different from steerable mount , i thought both are same , and what have it got to do with conformal anteena

I am not aradar expert but found a good explaination on a forum so sharing below---


I think we need to get some terminology straight first. A swash plate array (as proposed for Gripen and Typhoon, at any rate) is a normal AESA, just mounted on a mechanically steerable platform rather than fixed to an airframe bulkhead. This is completely different to a traditional mechanically scanned radar, the beam is also steered primarily by electronic phase shifting - physically turning the antenna is merely intended to expand its field of view. The reason for doing so is that beam quality of fixed phased arrays (both AESA and PESA) degrades near the edges of the scan envelope, limiting this type of antenna to around 60° off the nose compared to 80+°.

In summary, the cheapest way of using AESA technology is a simple fixed nose antenna. To regain the lost coverage compared to traditional mechanically scanned radars, two solutions exist: additional ('cheek') arrays or a swash plate installation in the nose. Both suffer cost, weight and power consumption penalties over a fixed nose AESA but expand non-degraded field of view back to levels formerly offered by mechanically scanned antennas. Cheek arrays are probably better in terms of maintenance requirements while a swash plate is easier to integrate (sensor fusion, interference), particularly for retrofits (Typhoon, Gripen). Both eliminate the transmitter as a potential single point failure (graceful degradation), so even the swash plate retains some of the maintenance cost benefits over mechanically scanned radars.

(AESA) radars are flat plates that can scan up to sixty degrees in any direction from directly ahead of them. By mounting an AESA radar on a swashplate, the swashplate angle is added to the electronic scan angle. The typical swashplate angle chosen for this application is 40 degrees, enabling the radar to scan a total angle of 200 degrees out of 360.

Okay i got it , i was lacking the name , well swashplate is something I have doubt , suppose it is scanning rightward , when it locate a enemy but in meantime there is a enemy which could enter radar view in far left, so it will be undetectable till radar direct toward left .

Meanwhile cheek radar won't face such a issue , but if nose bulge is in such a shape that we can add cheek radar as well as swashplate , we could manage a view where very little part of feild of view of radar with swashplate and cheek radar overlap and increase effectiveness while cheek radar providing much more angle of scan backward ,we can get radar view of 280 degree or so

What about AMCA mk2 ? Yes, yet to develop stealth technologies. Let's hope it will be similar or better than f35. More information/data always welcome.

Mk 1 itself will compete with f 35 , mk 2 will all together different beast .
