has anyone reported it?

has gaijin said that they dont care about that?

i dont think so

yes they have

and gaijin will just site the manual saying “this is what we use”

They should just model overspeed engine damage instead of this unrealistic wing break, it doesn’t make any sense at all. Irl jets just don’t lose their wings that easily

irl the engine doesn’t get damaged. its lifespan is just reduced faster

That’s not exactly true. The MiG-25’s engines were literally good for dump if it went full speed for more than 5 minutes

That doesn’t change the current mig25 we have. The engine will overheat avec mach 2.95. Who is the limit number in the current game of wing break.

Except that does change things, in a dive with reduced thrust the MiG-25 shouldn’t rip its wings at that speed

New way to test MiG-25 without custom hangar.

  1. Go to cutom lobby

  2. Find CC with MiG on testing

  3. Right click on it and add the vehicle to wishlist

  4. Go back to hangar → wishlist → preview → test fly

the heating i was talking about, pages 4 and 5 of manual

Again irl, its limited to make sure its engine survives for longer (it could exceed this).
But just like su-27, Gaijin will model this engine limitation as its wings ripping off.
su-27 example I was talking about (overperforming already and was already reported a year ago with no action taken)

Iirc the engines where more limited by IAS than by high match at high altitude

i mean it says its because of heat strength of the engine not because of ias or mach, so i just assume it is talking about the heat strength of engine

But as that one video @Blitzkrieg877 shared and per this manual, the mig-25pd is not restricted by thrust, drag, missile load (if carrying r40s its not restricted, when carrying r60s speed is limited due to heat damaging r60s) or anything like that. It could very easily exceed mach 3, and did so IRL. But, in order to keep the engines alive for longer, they limited the standard service speed to mach 2.83.
That’s why it’s a hard cut off line at 2.83, instead of being a curve/parabola like one would expect if it was truly a restriction of the air frame. It is limited just for service reasons

I read your comments guys and some were helpful some were insightful some little bit something but Everyone entitled to his opinion and what facts he believes in and What the information They carried but to believe a manual that were based on limitation of an aircraft instead of the maximum performance is just baffling to me because we know from the capture Mig 25 these numbers figures aren’t the maximum performance achieved by the airframe rather It’s based on safety limit to improve the longevity and endurance of such an aircraft that doesn’t have a lot of endurance to begin with Because the Mig 25 as we all know it’s not built from proper material

As for the figures of the speeds in the Mach 2.83 what is safety limit because we know from an a Israeli radar report mig 25 Egyptian mig25 moving at a Mach 3.2 I forgot at what altitude but this alone is a shred of proof make 25 can achieve more than what the manual said and I believe there are plenty of report regarding maximum performance And the Capture Mig 25 achieve speed of 1400 kilometre at low attuited and 9 to 11G of overload before suffering structural damage I will leave it at this and you guys extract what you want to extract from this

Can’t wait to be going Mach 3, launch an R-77 and watch it slowly fall back behind me due to the absurd drag.

fun fact mig-31 actually has same limit of 2.83 mach in service as mig-25

Shhhhhhhh… Gaijin doesn’t need to know.

Also I thought the limit of the 31 was lower than the 25?
