Vympel R-73 'ARCHER' - History, Design, Performance & Discussion

I mean 90 degrees is too much, I generally aim for between 30-40 and it gives much better results, particularly with my time to gain method.

Too much AOA actually decreases a missile’s turning performance to an extent. Firstly from just being less ideal to produce lift. But also due to the vectoring angle to keep it stable, your engine will effectively be less efficient due to its corrections at said angle / the thrust vector relative to CoM / direction of travel.

Yours deffinitly seems more stable at higher AoAs then mine does, i wonder how it handles the different ohysics rate on live servers to closed ones.

Also here are two aim9l missiles with mica tvc copy and pasted onto them. They are identical in every way except one of them has aoa limits while the other doesn’t.

Here is the funny thing. If you are only using CyMaxAoA than less than 90 is prob better BUT if you also set the guidanceAutopilot to 40 (and leave the other one on more than 40 (90 in this case)) the missile will be able to pull more while still usnig only 40ish degrees of aoa.
On r73s and sraam i set both to 40 but on every other missile i set the first one to 90 and the second one to 40

cymaxaoa is the cl at max aoa, not an aoa limit. setting it to arbitrarily high values will just end up giving it impossible lift coefficients

Eventually, hopefully Russia finally finishes their k-30/ modernization of it called product 300m. Looks like a asraam but with thrust vectoring and dual mode

Most accurate low speed r-73

What r-73 variant is this? From what I understand r-74e was a project that was shown off in 1997 then died? What are the specs of r-74e?

could just be referring to the RVV-MD and the article simply got the naming wrong/confused with the old naming system that just added an E at the end instead of RVV-XX like on newer export models

The image shown is k300 which is inaccurate, most of that stuff is ukrainian

likely has seekerhead similar to this one

looks like a straight rip off of asraam as i stated b4 but has tvc

ir ranges for 73

@Flame2512
you think 73 is overperforming or underperforming according to this?

Would have to check. Haven’t paid much attention to R-73 in game. Is that source reliable?

Radio correction channel for r74m2 is datalink

I see thanks a lot

Iirc the main reason RVV-MD/R-74M is advertised with more range is because one of the upgrades it brings from R-73 is a longer battery life, RVV-MD2/R-74M2 sharing said increased battery life as well as a stronger motor.

(Double reply yippieee)

Afair, K-74ME is basically export R-73M (R-73 w/ Mk.80M).

(I just realized the messages I replied to are like, half a year old… Quite incredible :Broken_heart:)

r-73 (e) irccm



in other words, r-73(e) is missing aim-9m type tracking suspension irccm.

I wonder if it’s only for Export version or both. Ngl this might actually make R-73 da best Fox-2 in the game, being almost unflarable up close but also being resistant to flares from fruther away

But kinematic Flares(such as the M206 sized MJU-47 & L7A7 (fits in ALE-40(MJU-11 magazine) et al.)), that retain the aircraft’s velocity after being ejected should they be added have a chance to be the nearest radiation source to the stored (predicted) location and so defeat the CCM technique at the selection stage, since it’s only a basic “nearest neighbor” check, and / or Trajectory, since itself is propelled and so doesn’t follow a parabolic arc.

So basically even if this was added, specific countermeasures do exist. The issue is to some degree that countermeasures are still just generic and aren’t even graduated (like for example Thermals)
