I see a lot of people use the term "MiG-23MLA" when referring to the MiG-23ML with Sapfir-23MLA/Sapfir-23MLAE radar.
To be fair, I've also noticed a lot of former Soviet pilots use this term in order to differentiate between the MiG-23ML...
...with Sapfir-23ML & MiG-23ML with Sapfir-23MLA. But I'm a snobbish MiG-23 fаnбоу, and as such, prefer to stick to nomenclature found in official documents.
First, some context. The MiG-23ML (product 23-12, product 3) with Sapfir-23MLA (product N003 or 323MLA) radar &...
& ASP-17ML optical sight (which includes the HUD). The previous MiG-23ML model had the Sapfir-23ML (product 323ML) & ASP-23DTsM. In order to differentiate between the two 23ML versions, Soviet pilots called the one equipped with Sapfir-23MLA radar the "MiG-23MLA".
The export versions of the "MiG-23MLA" were the:
▪MiG-23ML 23-12 version A - Warsaw-Pact customers,
▪MiG-23ML 23-12 version B - non Warsaw-Pact customers.
Both had the Sapfir-23MLAE (N003E, 323MLAE) and ASP-17MLE.
Now let's look at a few document issued by the socialist gods of paper&ink, to see what's actually canon:
▪MiG-23ML pilot instructions from 1980 (revised 1985). The aircraft is described as a МиГ-23МЛ with Сапфир-23МЛА, ТП-23М & АСП-17МЛ.
Capable of using Р-3С, Р-13M, Р-13M1, Р-60, Р-60М, Р-23Т, Р-24Т, Р-23Р & Р-24Р missiles.
There is also mention of the older model МиГ-23МЛ with Сапфир-23МЛ & АСП-23ДЦМ, and newer МиГ-23МЛД (изд. 23-18) with Сапфир-23МЛА-2.
No МиГ-23МЛА is mentioned however.
▪In "Практическая аэродинамика самолетов МиГ-23МЛ и МиГ-23УБ" mentions only MiG-23ML, even though the aircraft referred to is equipped with the Сапфир-23МЛАЭ and is capable of using the Р-24 according to pages 8 & 142.
Again, no "MiG-23MLA".
▪Finally, the R-24 missile employment manual. MiG-23ML with Sapfir-23MLAE radar, no mention of "MiG-23MLA".
In conclusion, I can't find any evidence of for "MiG-23MLA" being allowed by the Soviet bureaucratic gods of paper&ink.
And if someone gets the idea that MiG-23ML 23-12A can be considered "MLA" then "MiG-23MF version A" should be called MiG-23MFA.
All of this justifies my disdain and snobbish attitude towards those who polute proper MiG-23ML lore with their "MLA" heresy. So, Gaijin please, stop this BS!

One important fighter aircraft performance parameter, for close range air combat, is turn rate [°/s]. I will be comparing the maximum sustained & instantaneous turning ability of the MiG-23, with that of other contemporary fighters.
1▪Timeline
To identify the fighters contemporary with the MiG-23, and understand how they rank chronologically, I've made a list of "first flight dates". Keep in mind that, "first flight" date does not equate to "service entry" date.
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.
There isn't that much online info available on this subject. Here's what I could find...
According to the Su-15UT manual (two sear trainer) with two Tumansky R11F2S-300 engines (6200 kgf each), 6030L of usable internal fuel volume (5005 kg at 0.83 kg/L, T1 grade fuel). By my estimates, total internal fuel volume is 6140L (5096 kg at 0.83 kg/L).
Limit load factor of n=5.0, when clean with 4400 kg of fuel remaining, or with two R-98 missiles & 3800 kg of fuel remaining.
The B-58 was the most technologically advanced aircraft of its time. A Mach 2, wasp-waisted war chariot, drawn by four J79s, including silver brazed stainless steel honeycomb panels in its design.
But before getting into the technical stuff, some context.
The XB-58/YB-58 (aircraft № 1, tail number 5660) first flew on November 11, 1956, made at the Convair plant in Fort Worth, Texas. At this stage, it was without a belly-pod, tail gun, and was equipped with the J79-1 instead of the J79-5.
The first 30 aircraft (YB-58) built were meant to be used for development & flight testing.
You can see here & in the previous picture, among the difference from later aircraft produced, early YB-58s had small movable surfaces inboard of the elevons, called resolution surfaces.
Spike inlets, the TsAGI way.
Soviet vs. Western designs🧵
One of the most common design of air inlet used on supersonic aircraft is the axisymmetric diffuser with external compression (which is just a fancy way of describing the spike/cone inlets of the...
MiG-21, Su-7/9/11/17, Yak-28, Tu-128, F-104, B-58, F-111, the Mirage family, Lightning, Lavochkin La-250, Mikoyan & Gurevich SM-12/12PM/12PMU, Ye-3U, I-7, I-75, Ye-150/152, MiG-23PD, Sukhoi P1, T-37, Saunders-Roe SR.177, Bristol T.188, BAC TSR-2... I think that's all of them 😮💨.
Note: the Lockheed A-12/SR-71/YF-12 have mixed (interna+external compression).
I've discussed the basic principle of axisymmetric supersonic inlets with external compression & differences between the small/large nosed Fishbeds previously in this thread.
Here, I'll gradually be posting various random MiG-23 themed stories, comments & opinions by pilots or maintenance people, collected by me.
