well, with 2 people saying that it is horison line i am gonna believe it without any future proof anyways.
He’s watching us
Could watch that for hours
i feel this
i wish they remove the 1 week limit, or increase it
Found a cool size comparison of different Russian engines.

To my understanding
RD-33 (MiG-29)
R179-300 (Yak-41?)
Al-41F (MiG 1.44)
D30F11 (Su-47?)
Al-31F / Izd.177/177S (Su-27 family)
Mig-31 iirc
According to Wikipedia (best source ever, I know) the MiG-31 uses D30F6, and the Su-47 uses D30F11.
Both actually, Su-47 airframe and MiG-31 both use D-30F enignes. Difference between F-6 and F-11 is not known, because F-11 is pretty much only exists on a single airframe and never was mass produced. From random comments on different sites that i could find, changes are mostly engine controls placement and so on, internally and prerformance wise it is D-30F-6
Su-27M program actually considered most of the engines listed here.
Some of those would be… interesting…
Like R179 or D30.
… or RD-33.
This, as well as newer 177s were the ones that weren’t considered. But R-79-300 without rotating nozzle (R-179-300 was a proposal for Su-47, my bad) was considered, D-30F was considered and Izd. 20 (AL-41F) was the one that chief designer considered the most, but in the end… not even AL-31F with thrust increase was made.
Military wanted Su-27M right here and right now, and it to be not worse than Su-27S, and without any significant changes… And then USSR economy choked itself…
Many such occasions.
I am kinda scared to think what USSR engineers would cook if they had similar “budget” to their US colleagues
You’re missing the other half of “The Lockheed Equation”.™
Lots of Money, AND Lots of Drugs.
Hey, we made literal steel bathtub with engines that take 75% of internal space that goes Mach 3 without any drugs. While US had to buy titanium from USSR for their recon jets that only could take off on min fuel and had to refuel mid air several times.
Piece of Junk vs Piece of Junk.
one rips itself apart at its top speed (MiG-25), the other pees itself while it’s sitting on the ground (SR-71).
Russia has the opportunity to do the funniest thing with R-74M seeker + R-77M body
Actually speed limits on MiG-25 are due to increased instability and not structural limits
