Author Topic: Mig25 mach 3 capable? (Read 10238 times)

senna · « **on:** January 29, 2004, 07:39:32 PM »

I've heard that the Mig-25 could not do mach3+ but in numerous books I've encountered I read the max speed of the mig-25 was mach3+. Does anybody have any information or factual proof that it could do mach3+. Can a mig-25 catch an SR-71, I mean actually intercept one. I dont mean being able to shoot at one but be able to take off, vectored to catch an sr-71 and fly wing to wing with one? I remember reading that mig-25 pilots would sometimes try to go mach3+ and basically over spin their turbines etc... and ruin their engines. Anyone know anything about that?

Although I don't have the reference handy, I do seem to rememberthat the Foxbat was indeed capable of mach 3 flight.

However, seeing as how the performance of the blackbird is for the most part still classified AFAIK, and given that the blackbird is capable of flying at 80K + i sincerely doubt that the Mig25 would ever have had even the remotest chance of flying wing to wing with it.

cheers,

It can sprint to Mach 3 but the engines need to be replaced after that flight. No it cannot cannot catch an SR71, which is capable of cruising at Mach 3 plus.

Dont think a mig-25 could catch an sr-71 either but dam, what a beautiful bird.

they were a hair shy of mach 3 with a 68k max alt .

I seem to remember that the Soyuz/ Tu R-15BD-300manskii turbojets couldnt stay together for much time over mach 2.68 or so .( material related failures )

The Mig-25 was designed as a counter to the Rockwell B-70. When that bomber was cancelled the Mig had no reason to exist. Many fine aircraft came out of the Mig Design Bureau but the '25' was not one of them.

Wonder what a mig-25 costs these days? Still think it makes a good interceptor for a third world country.

Well Roscoroo, your links show mach 3.2 at altitude for the Foxbat A.

Although different info from the 2 links, but numbers are close.

Thanks for the links

You can poke fun at the Mig-25, but the fact of the matter is that the only air to air kill of a US fighter in the past 20 years was from a Mig-25. It shot down an F-18 in the Gulf War, then sprinted to safety.

Great, a modern day La7.

Did they ever find out what happened to M. Spiecher? (not sure if I spelled his name correctly.

i just tossed up the links ... what i stated was what they taught us about the mig 25 back in my AF days .

"the mig 25 could knock at the door of mach 3 but couldnt substain it"

I dont beleive it could go to 3.2 as for alot more forces come in to play at its alt sooner then they would at an alt of 80k .

they next question here should be ....

How many of them cracked up trying to go that fast ???

the MiG25 was going to be used to intercept and shoot down US missles i think. MiG 25 is the worlds fastest pure fighter if i remeber correctly, but i think it eat fuel like i dink water after running a mile.

only mig i really dont understand is the wierd looking 31. 29 is much more appealing to the eye than that ugly beast that the mig 31 is.

It didnt destroy the Migs engines to run at Mach3, but they did need to be overhauled/maintenanced once the aircraft landed.

Victor Belenko, the Foxbat pilot who defected in 1976, stated that the top speed of the MiG-25 was Mach 2.8, but flight above Mach 2.6 was difficult because of a tendency of the engines to overspeed. Victor related that MiG-25 pilots were in fact restricted to flying below Mach 2.5 except with special permission.
