I know one thing, R-73 was one of the best AA weapon for close combat, better than AIM-9 at that time, for sure. Now new AIM-9 could be better and it is normal, I cant imagine to publish new weapon that is worse than previous. But also russian developing new R-73 and it is only question of time, where we will be able to compare new one with new AIM-9. And one think for the end, you can have older R-73 or AIM9 and win AA combat against modern one, it depends mostly on other things that only on weapon. Also russian developing hot seaker warning system so that could be critical in dogfights. But I dont know status of that developing. So it is only information. Some photos are also on internet of that warning system.
