R27ER overperforming?

Ive seen many documents stating the R27ERs only hit 4.5 mach ? 5.8 seems a stretch

where does gaijin get sources saying this goes mach 5.8

I always thought the R-27ER’s performance was a bit of an exaggeration especially its unrealistic speed.
Gaijin 100% should provide the sources they use for modelling all of these vehicles and weapon systems, although they definitely have to guesstimate for modern stuff.
IRL the R-27ER was a miserable missile with bad electronics and reliability, although I could be wrong on that as I haven’t researched it much recently

It doesn’t go mach 5.8:

Sometimes statcards be wrong.
I’ll test again with Su-30SM, but I doubt I’ll see it even hit mach 5.

i think the in game stat card is just wrong it never reaches mach 5.8 in games

Aah thanks, game statcard may just be inaccurate again. I’ll try and test this myself
I gotta get the SUkhoi jets man

it is, like most stat cards tbh

yep, missile is still cracked tho lmao IOG + DL and top speed of like mach 4.10-4.20 on that thing is crazy

Yup its such a pain in the ass to evade half the time. Gotta notch, chaff and beat its IOG by changing altitude . A launch below 10 or 5km though you might as well J out

Test with the SU-27SM instead. The SU-30 is a bit too heavy and slow for a fair test while the -SM has the best FM in the family. If that’s not fair just use the regular Su-27

here, get this book for data on r-27

i hit some goofy clips on some guys despite loosing lock multiple times on them but the IOG+DL combo carried to hard

Update with Su-30SM [stronger radar so I could launch it further away]:


Peaked at mach 4.24. Might reach 4.4 if it doesn’t maneuver too quickly.
Launch parameters: 10,000 meters, mach 0.92.
Which is how top speeds are obtained IRL. That 4.5 citation will be around 10 - 12km high up cruising at mach 0.9. If you go faster, you can probably get all missiles to go faster.
The mach 4 AIM-7 doing mach 4.17 in a maneuver as AI is too low. All cause the starting speed was faster.

@zaedbe
The radar range matters more than the vehicle itself for this. Though I can’t always predict missile movement.

Having spaded all Russian Su-27s (other than -34) I get that the earlier radars are absolutely terrible but I assumed you’d launch it at absolutely max top speed to see if Gaijin’s statcard here is true in any circumstance even if getting a lock-on is tortureous

jeez thats insane

No, they run statcards based on mach 0.9 and 12,000 meters almost always.
So it’s a statcard issue.

Love these tests though, gotta get info somehow

Sensor view is the best thing they added to the game.

1800 m/s * 3.6 = 6480 km/h
1800 m/s divided by 340m/s = Mach 5.29

Hypersonic missiles are in-game now? :D
