Mikoyan-Gurevich MiG-25 & MiG-31 Foxbat / Foxhound - History, Design, Performance & Dissection

i think they should just start to slowly over heat past mach 2.83 like how the WEP on the 262 cooks the engines after a little bit

over heating does damage

just hope the MIG-25s a premium event vehicle

Event vehicles dont have premium bonuses, only Battlepass ones have.

Engines dont overheat past 2.83, that starts at much higher speed. 2.83 is just safe limit, past 2.83 theres a chance to reduce engine life but in reality flights past 2.83 were no issue.

Verified by pilots too. Theres a lot of accounts of pilots designers etc from flights above Mach 3 with no issue

need libyan/iraq/syrian MiG-25PD as squadron (they have 60 large flares and SPO-15)

I do not think it is possible. Cockpit weapon indicator only has R-60 and R-40 on outer pylons

This indication from MiG-31B or BM?


found another MiG-25PD with SPO-15, this one from Azerbaijan it seems

B and BM share the same indicator afaik

But this one doesn’t have R-77 and R-73 that BM most certainly can use

My apologies, I had them mixed up.

i wonder what are those 13s and “КР”? are on the outermost indicators. MIG-31B has set of outermost wing pylons, but they are for fuel tanks iirc

I believe 13 means wing tanks and KP was a planned Air to ground launched missile for the MiG-31 that never ended up developing

Oh, good to know, thank you. About R-37 on wing pylons i only found unconfirmed info that it was mentioned on brochures for MiG-31FE, but it is unknown if Russian MoD ordered BMs with this capability

are you talking about kizvy? are you plain brain broken?

r33 is a Sarh missile right?

Yes

False. There’s no, “no overheat issues past 2.83” nor “its just safe limit”.
It depends on time spent at high mach numbers as you can see. Under Mach 2.4 the engine can exchange the heat with air at a faster rate than it gains it. Above it and you find out the exchange rate is not fast enough thus the engine heat up. Spend more time there than recommended and the engines run hotter, metal loses strength and wear and damage takes place which leads to failure.

Either way, gameplay wise you’ll not be able to fly constant Mach 2.83 for more than 5minutes without running out of airspace(from corner to corner at M2.83).

Its not that underperforming. Exact range as described in the manual for pulse mode
Only 3 things are that it currently has an ACM mode which it never had, the CW transmitter moves with the antenna rather than being fixed to the front and the beamwidth is larger(2.5°) than it should be (2.3° page 487 <485 in doc>) but you cannot use datamine to prove it.

As for the max lockon distance being 60km. Page 467(465 in the doc) of the PD, hopefully it helps. All radars suffer from stupid limit like this.

Also where do you get the 5G permissible? All I see is 4.5Gs which leads to =>6.75 Gs destructive

Again the document you have provided underestimates. The real pilots and designers often did flights past 2.83 at varying lengths with no issue

It’s not a hard cut off limit. The designer of the plane said it was only theoretical simply to extend the lifespan of the engines, but that its pilots did in fact not abide by it.

We have recent interview of Indian MiG-25 pilot who literally said that they flew past 2.83 and that “He has never heard of an engine melting” btw

If you want to limit it at 2.83 because thats what manual says fine but to say its a “hard cut off line” is just false

“What is the fastest youve been in the MiG-25 Foxbat?”

“Oh we were limited to 2.83, the aircraft held a speed record of 3.2, we have exceeded 2.83 lets put it that way, You will find write-ups that the engine melted above Mach 3, thats why the limit is 2.83. We have not had an engine meltdown and let me tell you that we have exceeded 2.83”

Do with that what you will but this is one of many claims that make it clear that even past 2.83 it doesnt melt lol
