It's clear that, although the MiG-23ML can turn competitively with the F-14A, the others are beyond the MiG-23's turning ability. And, keep in mind that the F-15A/C data is at 97.7% engine trim (as opposed to the 102% wartime trim for F100-PW-100), meaning that the gap would be even larger.

Add to this, the fact that the MiG-23ML has a (static uninstalled thrust)/(combat weight) = 0.997, compared to the F-14A's 0.785, indicating that the MiG-23ML might be competitive with the F-14A in ascending oblique turns as well.

The MiG-23ML, even with χ=33°, is outturned by the F-15A, F-15C & F-14D, by a fair margin. The F-14A also outturns the MiG-23ML, but by a lesser margin.

We do see one pattern emerging. Most J79-GE-10/17 powered Phantoms (F-4J/E) do comparatively better the higher the altitude. It seems that the later J79 versions gave the heavier F-4J/E/S, improved turn rates at higher altitudes compared to the lighter F-4B/C/D/Ns with J79-GE-8/15.

Same story with the USAF F-4E. MiG-23ML with χ=45° is similar to the hard-winged (non-slatted) F-4Es (Blk.38 & 41), it gets beaten by the slatted F-4Es (Blk.51) higher up, and the MiG-23ML with χ=33° beats them all.

So far, it's clear that the MiG-23ML with χ=45° is at about a "non-slatted F-4 Phantom" level of sustained turn rate. MiG-23ML with χ=33° outturns them by a wide margin at low altitudes. The F-4S, is the only Phantom that can put up a good fight (at the higher altitudes, at least).

The lighter, early F-4Js, with J79-10 engines, can just about outturn the MiG-23ML χ=45°, but the heavier, late Js can't. The F-4S is a rough estimate based on the little info that I could find & verify. It's the best turning Phantom, though it too loses to the MiG-23 with χ=33°.

Czech pilot, Josef Miler found the 30° position good too: "I found that the airplane flies much better at 30°, and that the aerobatics are more pleasant [...] & felt rock solid in the air."
Here's Miler, puting the χ = 30° through its paces at České Budějovice (elevation 432m), 18 June 1994.

8 ▪ Maximum sustained turn rate
Maximum sustained turn rate, as its name implies, is performed at constant speed & altitude. It is highly dependant on lift/drag & thrust/drag, as well as lift/weight, but limit load factor can also play a role for some aircraft at lower altitudes.

...10230 kg for the MiG-23ML, which matches that found in some aviation books. Doing the same for the MiG-23UB, I get 10945 kg. And using a Polish MiG-23MF load-out table, I get 10860 kg.
⚠️These values will be used to calculate the combat weights.

For example, the Mirage F1 first flew in December 1966, but entered service in May 1973 (first squadron delivery). For the Mirage 2000, these are March 1978 & July 1984 respectively. So quite some time can elapse between the two events.

MiG-23 turn rate🧵
One important fighter aircraft performance parameter, for close range air combat, is turn rate [ω, measured in °/s].
I will be comparing the maximum sustained & instantaneous turning ability of the MiG-23, with that of other contemporary fighters.
