We (USSR) can get MiG-25 in two variants (which would be useful). Interceptor MiG-25PD and fighter bomber MiG-25BM. In theory, Japan can only get the MiG-25P (captured) version, which would have very limited capabilities. I don’t know if it would be useful (no KDS-155, no R-60M and only R-40R/T).
Add an aircraft less maneurvable than a Tornado?
Sure, would be fun to no longer be the whale aircraft
Not big deal in simulator.
Well when the US first saw the MiG-25 they saw massive wings and huge air intakes. So they assumed it was some new “Super fighter” and the USSR just played along to scare the west. Then the Israelies clocked it on radar doing mach 3.
So, Like you said, they created the F15 in a panic,
We now know thanks to a Soviet MiG-25 pilot who defected to the west and crash landed in Japan that the MiG-25 isnt as good as the Soviets said it was. The MiG had huge wings because it was made out of titanium because the heat from going Mach 3 would melt aircraft aluminum. It also lacked a look down radar, although this was later changed with the MiG-25PD. They also learned it could not turn, and its engines were taken from balistic missiles and therefore not designed for long flights, It is true the MiG-25 is mach 3 capable, but only for a short ammount of time, soviet MiG-25 pilots are often quoted saying how frusturating it was to intercept the Sr-71, because the Sr-71 could go mach 3 for much longer than the MiG-25.
Another interesting thing about the MiG-25 was it too was designed in a panic. The US was in the process of creating the XB-70, a mach 3 capable bomber,.
It would make the F104 look like a turn fighter
Probably not, though would be fun hunting them in the F3, I doubt the Mig-25s had that great of an RWR and would probably leave them rather vulnerable to an SARH intercept
SPO-15 Beryoza, so practically same as MiG-23MLD (what is pretty good). +R-40TD what can be very deadly if it will be at least same effective as R-24T.
SPO-15 is not actually that good, at least not compared to the RWRs used on the Tornados for example. But would provide some warning at least. Though I doubt you’d ever get into a notch in time. So 4x maybe kills then.
Though I doubt you’d ever get into a notch in time.
That’s what the F-4S and F-14A also thought, on which I then committed genocide by MiG-23MLD. xD
And F-15A should have 0 CM as well. Oh wait…
we need mig 25 with the 3,500 km/h speed
Could be wrong but I was under the impression that while it could do mach3+, doing that could cause serious damage to the engine. For example, the foxbat the Israelis detected had to apparently ditch after the engines stopped responding properly to throttle commands. It’s the anecdote I’ve heard but i haven’t yet looked for a source.
The “safe speed” as far as I know is Mach 2.7 that is, any faster than that and the engines tear themselves apart.
there is no real proof of that just western propaganda, what we know for sure in testing the plane reached 3500 km/h and could reach 4000 km/h but due to safty concens they did not forced it.
What radar MiG-25PD use? Its all-aspect PD like on MiG-29, head-on PD like on F-14 or MTI as on MiG-23 (I think this one based on fact that it was developed from Sapphire-23)?
Yes, that too. The engines were taken from either a cruise or balistic missile, so they werent designed to last a while
MiG-25 PD uses Sapphire-25 radar
MiG-23MLD uses Sapphire-23 radar
Both radars are almost identical.
Both are not pulse-doppler radars, but non-coherent radars with clutter-referenced moving target indication (MTI).
Clutter-referenced MTI means that main lobe clutter works as a reference signal. Low PRF are also used. These two factors specify following additional limitation of such MTI in comparision to normal pulse-doppler radars with HPRF or MPRF:
- Radar can’t filter out non-moving ground surface and at the same time slow moving targets like cars, trains, sea waves at high wind, chaff at wind e.t.c - all create clutter on the radar scope.
- Wind-moved clutter like chaff and rain clouds can be filtered out in a special separate MTI mode. In this mode ground clutter is not rejected. Doesn’t work if turbulence is high.
- Radar can’t detect moving target if the angle between radar (own aircraft) velocity vector and the antenna direction is not small enough - 15 degrees may be too high.
- Don’t detect moving targets without presence of ground/chaff clutter on the same range. Or it should have automatics which disables MTI in range cells where ground clutter doesn’t present.
So it means that it can detect on smaller range but still can detect as stated in manual.

Translation:
The “BS” modes (“BS3”, “BS2”, “BS1”) are recommended for use with the parametric amplifier enabled. The radar system remains operational in “BS” modes even under mild weather conditions; however, in this case, the detection range is slightly reduced, especially during attacks on targets flying above the fighter, and tracking interruptions may occur.
“БС” mode is an MTI mode, which is used to remove clutter from rainclouds and chaff, not ground clutter. Looks like it has MTI bypass circuit if clutter doesn’t present on the given range or something like this.
According to manual (attached pictures) can be BS1 and BS2 modes used when attacking target from top to bottom (against the background of the earth).
I’m pretty positive it’s BR will be lowered at a later point. Like, 99.8%.
