The AIM-54 Phoenix missile - Technology, History and Performance

R27EP or any radiation homing missile in a2a use would be like shooting a SARH at a low alt target but all the time.

Not to mention it’s questionable if it was ever even used, what avionics it required, etc. Unless the sources are in Russian I can’t find any info on it beyond ‘passive radiation missile’

R-27EP definitely is in use, its operation is detailed in the 9-13S manual. Its a pretty interesting missile

because it was not exported anywhere

Do you happen to have any idea what NATO bands the seeker tracks? And if it tracks main beam or side lobes?

unfortunately it doesnt specify anything related to bands just operation tho the missile can definitely track a MiG-29 radar since the manual specifically mentions using phi-0 mode (IRST with radar off) and aiming by boresight until NP (launch authority) appears in order to prevent the missile from tracking the fighter’s own radar,

though interestingly enough it does seem to have some sort of SARH mode aswell since it describes guiding the missile using an STT lock the same way you would for a R-27R/ER

So at the least I-Band, based on what I’ve read it was of limited usefulness and really lack accuracy. I’m betting thats because it’s not tracking a tracking wave form and just search emissions.

Oooohh, someone is working on a future update?

Ahaha no just a passing interest, other than ARMs I don’t know of other passive missiles. I suspect its because tracking a moving ground target based on target emissions is substantially easier than a fighter target.

It seems to guide the same as the R-27Rs using the radar, only other way I can think of thats likely is it uses inertial+DL information up until the target and guides via STT lock until it gets so close to the target the emissions of the target radar are stronger than the launch radar that it terminally tracks that signal.

Which is feasible, however the manual doesnt specify either or, just that it can be used with the radar the same way you use an R-27R/ER

No it’s not like that

what do you believe it to be then?

Can we move the discussion to the other thread please?

why was this post flagged? are you mods mental?

It was flagged by people reading the topic, not by mods

then people are taking this shit too seriously

Hey, could you maybe flag/hide/remove all the R-27 post as off topic instead of contributing to it? Its been about a day now where the whole convos been about the R-27 and its getting annoying, particularly since other ppl have been abusing the flagging system to remove any post they dont like thats still on-topic

Its not the mods, the pro-russian players love abusing the post flagging system and the mods never really do anything to punish them. Its really not that uncommon

Theres a lot of NATO S/ARH (such as the AIM-54 iirc) that have home on jam, which is technically passive tracking

We wouldn’t need to clarify nonsense so often if you’d stop posting it.

The AIM-54 misinformation you post was bad enough, Western equipment enthusiasts were posting misinformation about the R-27 in here (Ziggy & Co) and that had to be dispelled. The topic carried on despite multiple efforts on the Ru enthusiasts side trying to bring it to the relevant thread.

To put us back on topic, we could certainly discuss the capabilities of the AIM-54 to do some similar passive guidance such as home-on-jam. I wonder what the difference between HOJ and anti-radiation guidance is? (In relation to effectiveness vs fighter sized targets).

My understanding is that if a target is jamming, it has a constant emission in whatever radar band the launching radar + attacking missile use. So as long as the target keeps jamming, all the hardware needed to detect the signal is already there for active homing. So it probably just changes the guidance profile since it has elevation+azimuth data but no distance data. Like a heat seeker but with radar.

Actual anti-rad is more sophisticated since it has systems for distance calculation, proper inertial guidance, etc. And it can guide onto more bands.
