Ground based air defence has certain inherent advantages to it too.
And air to air bvr engagement is still very limited.
I had asked this a former pilot and he had said that over very long distances things like battery life of missile , it's seeker etc everything comes into play. And they are trained not to waste a round untill they can actually have confidence that the missile if having proximity fuse will atleast do some kind of damage.
And for that they will usually fire the R27 family between 10-30 kilometres only. And the advertised range of that R27 in ideal conditions is 75-80 kilometres.
That is BVR engagement.
Yeah, so he's talking about very old tech. The IAF has only very recently started operating new tech via the Rafale. LCA Mk1A will be our next one, followed by MKI MLU, the big one. Everything else before Rafale have very low range, made worse with altitude. And it's the new radars that give that "confidence" he's referring to.
That's the actual range of the R-27 in combat conditions with the Mig-29.
Untill you can get the cruise missile to be able to withstand atleast 30-40 G, it won't happen.
Nah, that's not necessary. They compensate for lower agility via a larger warhead. The G performance of missiles like the R-33/37, AIM-54 etc aren't impressive. Gets worse with the S-400's long range missiles as well.
Seekers have also advanced to the point where you get HTK even with very low Gs, like Patriot.
In fact missiles like Astra Mk1, AIM-120 etc have very low G performance during the end game phase. Performance gets a major boost only with dual pulse or ramjet.
Eg, for VL-MICA:
From 0 to 7 km MICA has maneuverability of 50g, however by 12 km this is reduced to 30g as energy is lost.
