First document you provided translates too “Radar homing heads” is that not ARH?
Second document mentions a “Semi-active RGS-31”, but the source I found indicates it had both:
“It is equipped with the ARGSN with a two-stage guidance system - inertial with radiocorrection with transition to active radar homing on the final flight section.”
So that source does not contradict that.
Quick googles of “RGS-31” comes back with sources that refer to it as a “Active radar homing seeker” so… That might be further evidence of it being ARH.
RGS-31 active radar homing seeker, the seeker can lock on to the target before launch or it can acquire the target post launch. - Source
So its hard to say for certain, but I reckon it is a combo SARH/ARH seeker
Does not difinitively prove that it only had SARH seeker. Especially when searching for info for the RGS-31 comes back with info on ARH seekers. Those sources dont prove difinitively
It’s clearly SARH, because it’s says semi-active, not semi-active-active or anything else. Source on internet are just unreliable garbage. You can read on first photo by who this book was written.
Also, on the R-27AE, 9B-1103K is a derivative of 9B-1348E seeker on R-77 (quite easy to see the similarity of their slotted array), it was offered as active seeker for R-27AE version, however, no one took on the offer, so just like R-27EA and R-27EM, it never went to production.
9B-1348E is for RVV-AE, R-77 that has never gone in mass production used 9B-1348
It’s not, they are two seperate projects that were conducted at same time with usage of same technologies and R-27A being cancelled due to money and focusing only on R-77
Personally I hope not. Because R-27EA/EM has much longer range than the most AMRAAM variants. I believe it has excess of 120km range, while the early AMRAAM (120A/B) has more around 70-90km range, and with C it only went up to around 100km.
I would hope that R-77 is added, because otherwise it would seem unfair, but IMO AIM-120A/B vs R-27ER seems like a decently fair fight. The AMRAAM player has to get within range of the R-27 to launch, and still has to guide the missile most of the way, but the R-27’s range makes even that dangerous. Not saying the R-77 isn’t necessary, it is if the AMRAAM is added, but the R-77 actually has less range (iirc) than the R-27ER. So it would be a tradeoff between more range (27ER) or easier use (77), to fight the NATO ARH, since the AMRAAM way outclasses the Sparrow.
