It have. Saphir-25 used on MiG-25 is bigger derivate of MiG-23 radar Saphir-23 which have this ability. However, don’t be confused by the Saphir-23’s current lack of performance in the game. It is proven on the basis of manuals that the radar lacks key modes.
Yo and MiG-25PD/BM can use also KDS-155 dispensers what is 60 countermeasures. I dont see any obstacle to add MiG-25PD and BM variants.
Even better, because it could turn tighter. G limits are relative, and the 4G limit imposed on the MiG-25 wasn’t a maneuvering limit in terms of aerodynamical capability.
Leaving aside the massive airframe stresses incurred the Foxbat also had a rather nasty habit of going into unrecoverable flat spins if pushed beyond it’s limits. A few crew deaths as a result. I’d say that would fall firmly into the ‘hard aerodynamic’ limits similar to ripping wings or tails off other aircraft when overstressed.
It’ll handle like a Tornado fully loaded with fuel and bombs - at best. Be in no doubt, it’s a dragster, not a sports car.
Flat spins can happen because of excessive AoA or unusual combinations of AoA and roll/rudder. Not directly because of G-load.
4G at something like Mach3 is barely a turn.
I can fairly belive that MiG-25’s aerodynamic limitations won’t allow it to do something like 8G at 700kph, but it’s certainly able to do that at high speeds when structural integrity is not considered
From the rather comprehensive look at the Belenko airframe. Specific quotes:
"Belenko’s particular aircraft was brand new, representing the very latest Soviet technology.
Welding was done by hand and construction was relatively crude. As in many Soviet aircraft, rivet heads were left exposed in areas that would not adversely affect aerodynamic drag.
The aircraft was built of a nickel-steel alloy and not titanium as was assumed (though some titanium was used in heat-critical areas). The steel construction contributed to the craft’s massive 64,000 lb (29,000 kg) unarmed weight.
Maximum acceleration (g-load) rating was just 2.2 g (21.6 m/s²) with full fuel tanks, with an absolute limit of 4.5 g (44.1 m/s²). One MiG-25 withstood an inadvertent 11.5 g (112.8 m/s²) pull during low-altitude dogfight training, but the resulting deformation decommissioned the airframe."
I would say that dubious build quality, combined with some truly heavyweight engineering would make for an airframe you DEFINITELY would not want to subject to any high-G turns - at any speed really. Whether the aerodynamics or structure let go first would be a coin-toss to be honest.
Edit to add - I’m not disputing the MiG-25 would be a fun addition. However there seems to be this strange fixation with arguing that it would be far more agile than it really was. Even the MiG-31 - the ‘ultimate Foxbat plus deluxe’, heavily revised and toughened - has some very stringent limits.
I’m quoting from the Western observations of the Belenko airframe that landed in Japan. They would’ve been able to tell if it was machine-welded or hand-welded.
So they were either unable to tell the difference (not likely - let’s be honest, every expert was flown in as soon as they had the chance to have a look at a MiG-25 in the metal)…
Or the welding quality was so bad that they couldn’t believe it was done via machine. I’m entirely able to believe that to be honest, having seem the welding on a MiG-23, 21 up close…
29,000kg was ‘unarmed’ - so likely including fuel load.
This is an access hatch and it may have changed in the process or been damaged or lost and welded authentic
If you’re talking about propellers, they’re not from an airplane.
