I was replying to Su-30SM message.

Even for Su-30SM, I’m not claiming it’s the Vne (though it very well might be).
I was talking about maximum speed in level flight, but I was checking the speed for that one from statshark, since it’s not on live yet …
Also Su-30SM and Su-30SME are entirely different aircrafts, so sources for SME are not applicable to SM.
They differ in avionics IIRC
The airframe design is similar
The engine thrust curves have to be wildly different to account for such a drastic difference in speed … Possible in this case but I doubt it …
As for Su-34 vs Su-34E
It’s virtually impossible for the former to have a max speed of 1450 on the deck when the export version goes 1100 on the deck …
Su-30SM max speed Mach 2.0
You mean IRL (source?) or on dev server?
Either way, 1.75 to 2.0 is not that big of a difference
But in the case of Su-34
1450 vs 1100 on the deck
And Mach 1.98 vs 1.45 at altitude
Is a massive difference … It completely changes the nature of the aircraft …
IRL
That information is inaccurate and most likely it pulls the speeds from earlier data during development before the aircraft was fully tested and went into serial production.
The speed information matches what is given in the 2005 Rosoboronexport brochure for “Su-32 export aircraft” …
And that’s besides that fact that in the game it goes even faster than these “early” development marketing numbers, which were probably made with the hope of finding export customers to fund the further development of the aircraft.
Either that, or they had to limit it later due to safety issues …

Brochures are for 12500 thrust. Stand 13500 thrust.
Which aircraft are you talking about?
Su-34. Look at thrust numbers in Su-32 brochure and Su-34 stand
Su-30MK, Su-30SM and Su-30SME are completely different planes. Data for one is not applicabe to other.
1- Change from 125kN to 135kN doesn’t make you go from 1100 kph on the deck to 1450 or 1400 kph.
Again, sorry, but that’s an extremely absurd claim. The math doesn’t remotely math and you don’t even need to know math to figure that out …
2- The 2005 Rosoboronexport brochure lists the same speed figures and seems like the 135kN variants of the engine weren’t even a thing back then:
Stand photo is from 2012.
Yes
But it pulls the speed information from some older inaccurate sources …
The three official websites I showed you are from 2023-2025
Or perhaps the real speed wasn’t declassified in 2012?
That would be an alternative explanation for the 2005 brochure too …
In fact
UAC website from 2017 :)
Added this explanation to the bug report:
Older sources such as the 2005 Rosoboronexport brochure for (the export) Su-32 and a 2012 photo of a placard / show stand for (“the domestic variant of the”) Su-34, both list the same 1900 kph / 1400 kph (alt / deck) as maximum speed.
But those are the fake numbers, as the real aircraft speed was classified back then.
“United Aircraft Corporation” (UAC) which manufactures the aircraft, lists the aircraft performance specifications as “Classified” until Jan 2023:
This makes it clear that the older 1900 / 1400 (alt / deck) figures are fake … Because if they were real and present in the publicly and internationally available 2005 Rosoboronexport Su-32 export brochure (as well as the 2012 photo of the placard of the domestic Su-34 aircraft), there would be no reason for UAC to say “sorry we can’t tell you, it’s classified” in Jan 2023 …
Later, since around March 2023, the UAC started giving the performance specifications (and no longer listed them as “Classified”), which are provided in source number 2.
In essence … Seems like we have another “MiG-25 the highly maneuverable dogfighter” situation on our hands here …
here f-15 IRL vs WT:
(red line is its actual flight performance at sea- level, clean, 35000lb of weight)
Statshark adjusted so the f15 is at 35000lb as well

Damn If that’s true then the su34 would be completely useless
