Ken, what Myasishchev projects are included?
I have lots of model pics, drawings and the odd painting for M-18, M-20, M-30, M-31, M-32, M-34, M-50, M-52, M-54, M-56, M-57. M-60, M-70. Often with several variants of each design.
I was afraid that this might be the case, as Yefim Gordon (the king of ‘Cut and Paste’ writing) was involved.
Myasishchev’s bureau was reformed on 24 March 1951 to work on the Bison (“Project 25”). They then worked on the M-50/52 Bounder, which was unsuccessful, but in 1960 all work was terminated and they were reassigned to Chelomei to work on Khrushchev’s beloved missiles.
With Khrushchev’s fall from grace in the mid 60s, Myasishchev were reformed and allowed to resume work on aircraft. They were doing preliminary design work on new multirole bombers first as M-20 and later as M-18. They studied a vast range of possible layouts including canard deltas, tailless deltas, canard VG, tailed VG, twin, single and T style tails.
Undoubtedly the final M-18 design looks quite like the B-1A, but Myasishchev tried pretty much every possible layout and the M-18 design was felt to be the right balance between risk and performance.
Sukhoi’s T-4MS “won” in the sense it promised the most, but Sukhoi was considered to be too busy on the T-10 project.
Tupolev’s own design was basically a militarised Tu-144 and the Soviet Air Force hated it.
Myasishchev’s design was the right balance between risk and performance, but their factory was now producing missiles for Chelomei and they had no facilities to build a prototype.
So, Tupolev won the tender, with all documentation regarding the T-4MS and M-18 being passed to them. Tupolev at once rejected the T-4MS as too risky (even today, it would be a considerable challenge!) but considered the M-18 was a reasonable design and used some ideas from it. Initial designs of the Tu-160 show a blending of Tu-22M and M-18 influences, and as the design was refined it looked even more like the M-18.
The modified Su-35 also has a treated cockpit canopy which reflects radar waves, concealing the high RCS contribution from metal components in the cockpit. ITAE has developed a plasma-deposition process to deposit alternating layers of metallic and polymer materials, creating a coating that blocks radio-frequency waves, is resistant to cracking and crazing and does not trap solar heat in the cockpit. The plasma-coating process is then carried out robotically in a 22m3 vacuum chamber.
This is plasma desposition of radar absorbent material on the canopy
ITAE and its partners have also developed plasma-type technology for applying ceramic coatings to the exhaust and afterburner.
Plasma deposition of ceramics
ITAE has flight-tested a more exotic technology: the use of a low-temperature plasma screen in front of the radar antenna. The screen hardware is mounted in front of the antenna and is transparent to the radar when switched off.
When activated, the screen absorbs some incoming radar energy and reflects the rest in safe directions over all RF bands lower than the frequency of the plasma cloud. It switches on and off in tens of microseconds, according to ITAE.
actual Plasma used as a shield
Test facilities include large compact indoor RCS ranges for large-scale models and outdoor ground-level ranges with short pylons that can be used to test full-size aircraft (rather than the models used for US pylon tests).
Seems they have the facilities now.
The latest Agat seeker is claimed to implement new technical solutions and have a range up to 90km vs a 5 sq m RCS target. It operates in passive, semi-active and active modes.
SK you should know that add-on ECM control panels can be mounted in cockpit, as was done on the Su-17 series. So lack of cockpit controls doesn’t prove lack of ECM.
However, you are right that the MiG-29 was never fitted with external ECM pods. The fatback Fulcrums with their internal Gardeniyas were the only ECM-capable models.
R-77M is an updated version supposedly being studied.
K-30 is a short range AAM to replace the R-73. Drawings have been shown.
Yeah, its an LFS design from Sukhoi.
It is probably not too dissimilar in basic performance to the earliest AIM-120 models. However, the AIM-120 has had the benefit of continuous development and large bundles of cash invested in it.
I disagree with SK on why it never made large scale service though. I think its because Russia has no suitable platforms for it. Without a radar at least of Zhuk level its really not worth bothering with. The prime concern of the Soviet AF was missiles that outranged the opposition, and the R-77 was worse in this respect than R-27E.
The R-77 missiles that have been made have, IIRC, been put together by Vympel’s experimental facility and never put into mass production at a factory. Hence, they are basically prototypes still. There has never been an order big enough to justify setting up a full production line.
In case anyone’s still uncertain Stavatti is not a real company, but a guy with delusions. His planes look stupid as well 😉
A plasma stealth generator would appeal to the Soviet/Russian way of thinking. Its like the T-64/72/80 being upgraded with reactive armour, as opposed to building a whole new tank. If there was a promise of a small “black box” that would make expensive investments in new manufacturing technology and RCS research irrelevant, I can imagine it gaining approval. If it then turned out to be impractical/impossible, then they would be up the proverbial creek without a paddle.
The Russian laser guidance systems are basically cloned from the Vietnam era Paveway I.
One would assume that this makes them outdated today.
The Kh-23/25 series are derived from the ancient RS-2US AAM (AA-1 “Alkali”) and really are not comparable to AGM-65 Maverick, rather like if the US had continued developing the AGM-12 Bullpup.
The basic R-77 does not have a lofted profile. The older AIM-120 versions didn’t either, IIRC. The R-77M is supposed to have a lofted profile and new motor, and is presumably being funded by exports of the old (basically Soviet era) R-77 model.
I’m pretty sure the first two fan stages were coated in some radar absorbing material, but I’m not sure of the source.
The thing to note is that the Su-27 happens to have some very major “glints” in the front quarter, from its engines/intake for starters. Thus its front quarter RCS is quite a bit larger than the F-15s, for example. By treating the intakes, canopy, etc, the maximum (worst case) front quarter RCS is reduced by a factor of 10. The maximum detection distance of the said Su-27 by enemy radars is accordingly reduced somewhat.
The Su-35 article from IDR is here:

The US has done the same thing with its F-16 fleet (“Have Glass”, “Have Glass II” etc)
SK- you are wrong on this one.
There have been several articles in Avweek etc from a Russian bureau who have worked on RCS reduction. I can send you the article if you want. They said that they had cut the RCS on the Tu-160 to 1/6th, the Su-47 Berkut 1/10th, and the Kh-101 to 1/14th compared to the unmodified design provided by the OKB. The Tu-160 did undergo RCS reduction; the intakes were kept shrouded in public for quite a while to prevent the treatments becoming public knowledge. How many aircraft were modified, I don’t know.
Separately, they worked on the Su-35 cutting its RCS to 1/10th with minor modifications, including developing an aerosol based RAM for treating munitions hotspots.
The thing about RCS is very small things can contribute very large amounts to the RCS. By treating these hotspots, you can significantly reduce RCS. Not to the level of stealth aircraft, clearly, but potentially significant.
Russian companies have full access to RCS prediction software now, but they currently lack the manufacturing capabilities to implement real stealth design.
