The r-77-1 has a range of 110km same for the Astra.
USA rarely cite range vs altitude like we do, and they cite a nautical mile range for everything, heck they even cite it as between X & X+5-10 Nm like range to obfuscate.
About that 44km at 8km alt quoted in previous page; it was the initial design phase number that Dr Kota quoted sometimes, which is typical in dev curve. Upscaling happen gradually & it has happened with Astra as well. It hit the target drone from 12km alt at full stretch of 87km and low flying object, and during testing they pre-select mission capability at 75% of true capability for safety measure, ie just about as rugged performance for safe testing as you can get.

Tejas MK1A will be one hell of a versatile light weight fighter. We should definitely order more and increase the production to make quick delivery.
re that Hammer integration, ADA already did first phase during last financial year as we know, so now its fully mission cleared. Not surprising that now the bird is deployed in forward bases.
This NG-RWR that is coming along with ASPJ pod is even more advance than DR-118 Dhruti that is integrated as of now in MKIs and as advance as SPECTRA covering wide frequency range between 1 GHz to 40 GHz. MKI UPG. will have this same combo with two ASPJ pods instead of MK1A's one. Great update
All of it was in last financial years update, we might get to know something this year either from Astra micro/DP call or annual report.This NG-RWR that is coming along with ASPJ pod is even more advance than DR-118 Dhruti that is integrated as of now in MKIs and as advance as SPECTRA covering wide frequency range between 1 GHz to 40 GHz.

Had something about astra mk1 bvr too
Probably the only slightly interesting bit from the last seminar. Attached below
Also available on ADA site btw. nothing that much interesting, and some too technical system related.
Looking at the flight altitude, it is possible to reach this data at an altitude of 20KM, but now the vast majority of air combat occurs at mid to low altitudes
Max ranges are all for the peak altitude region, almost every bvr missile I think would go up high post release then descend on the target based on how its seeker performance is for detection range in the terminal phase.
Frankly, the entire concept of stealth fighters mainly originated for air engagement where the jet carries its weapons in iwb, thereby reducing its signature and drag which lets the jet work much more in free fly condition. Load up on external pylons will always affect a jet performance and detection RCS. Just my thoughts. If we are able to put an iwb, a very long range powerful radar and frequency selective surface treatment on a 4 th gen jet without stealth shaping, it would still perform very well at least in a2a mode.

The standards for each country are different. For example, Russia has two planes flying in opposite directions at Mach 2 and an altitude of 20000 meters, NATO standards at Mach 1 and an altitude of 10000 meters, and China standards at Mach 1.2 and an altitude of 10000 meters,
Aerodynamics plays the same way for all, now whether one side like to highlight what is suitable to them is another matter. Under a certain flying condition & altitude the parameter data of a certain air article is actually confidential data.
So what are we talking about when? according to India, the range of 110KM was achieved at an altitude of 15KM, so it is unreasonable to think that Indian missiles have reached the level of 120C
Astra hit a maneuvering target(drone) at its max range of over 100kms. No target drone flies at 20/25kms altitude. They usually fly under 7kms altitude. Stop running down Indian weapons.
Here is the official confirmation:
This is only in best possible scenarios. The launch platform in high altitude and non-maneuverable target drone in low altitude. Thus gravity will do most of the job. This particular test was to validate this scenario.
In a normal confrontation like Feb 27, this range is not possible. Lower altitude have higher friction and missile looses energy quickly. That is how you evade a BVR missile. By gaining altitude and giving high g's.
See how the range is defined for Astra Mk-3
Spot on. But what you wrote applies to every BVRAAM and not only to Astra as our Chinese friend is trying to imply.This is only in best possible scenarios.
