any info about the upgrades? im was wondering if that new helmet will be present in it

Do you really think that Real buyers use the Rosoboronexport website?..For example, Algeria when buying the Su-57 3 years ago?..

Spoiler

Not sure what your argument is here

The answer is no, and that’s why they could put fake numbers in public ROE brochures and placards etc, for so long, without any consequence …

Actually, the fact that the real buyers will ask for classified information rather than deciding based on public brochures and placards could be the reason why nobody actually bought the aircraft … I.e. they asked for performance data and when they were shown the real performance data, it dissuaded them …

Did you tried VPN to spoof your location as Russia? It worked for me some time ago.

sudo_su1 · March 16, 2025, 2:34pm

I don’t have a VPN from Russia to test
But either way, all we need is right there on internet archive

What you cant open?
ROE normally works for me (Slovakia).

UAC Russia website.

csla1972 · March 16, 2025, 4:54pm

Yep…its not working.

ID_Heaven · March 16, 2025, 4:55pm

Russian IPs work. Just checked. I am from KZ and it is unavailable, so probably even CIS IPs doesn’t work.

csla1972 · March 16, 2025, 5:09pm

I will little bit change theme…is M433 Raduga-VM thermal camera?

ID_Heaven · March 16, 2025, 5:12pm

You mean Su-34 recon pod?

csla1972 · March 16, 2025, 5:14pm

Yeah…UKR-OE.

Anonymous4245 · March 16, 2025, 9:16pm

Weren’t early Su-34 also fitted with non FM1 AL-31s? That would make sense if the export versions also get it.

That looks like major skill issue…
From the missile itself
It did fly way to high and in circles

sudo_su1:

It absolutely does not matter what engine was installed on it. It will not make it go from 1100 kph to 1450 kph on the deck …

Drag is proportional to the velocity squared and a small increase in velocity requires a massive increase in thrust.

But since the Mach 1.45 (From ROE) / 1500 kph (From UAC) at altitude and 1100 kph (From all three sources) on deck figure seems to be with the 125kN engines (as per UAC’s website), the devs could account for the increased thrust (to 135kN) of the better engines.
UAC’s website also lists a 2% reduction for installed thrust. So given that the drag is proportional to the velocity squared:

(135x98%) / (125x98%) = (V2/V1) ^ 2
V2/V1 ~= 1.03923
V2 = 1100 * 1.03923 ~= 1143 kph

So with the 135kN engines (instead of 125kN engines) the speed will increase from 1100 kph to 1143 kph (and NOT 1400 or 1450 kph!)
