    😮

    huh, what a madness to put a short-range “dogfight” tail-on only missile like the R-60 on the almost Mach3 recce Mig-25. Where did it happen? Not to mention the Mig-25 is fast as the R-60 missile which had uncooled Komar seeker,thus launch limited to Mach 1,85. When flying at subsonic Migs-25 had escorts equipped with R-60 missiles.

    Those UFOs are said to be able to zip from zero to mach thirty in a half-second.

    I will try to say something intellectual, so please do not be too harsh with me.:)
    Generally, traveling through earth atmosphere is going to see dramatic changes, much greater revolution when compared with the year 1903, when the Wright flyer took off for the first controlled, powered flight heavier than air. The idea of flying by using wings to create lift, tails to change flight direction we`ve gotten from the Mother nature will seem pretty primitive , the same as now another means of flight, the balloon.
    I dare to say this technology is just one hundred years away. Fundamentals have already been invented, look for quantum optics branch for further details. When speaking of Ufos, they just use this tech to remain hidden playing with our belief, whether it is fiction or fact.

    P.S. remember, the future in the aviation is the light.;)

    So, a typical three-position site would have had 18 ready to fire weapons and a maximum of 144 reloads, with 18 of them on the rapid reloaders and the rest in storage.

    I hope you find it useful.
    As you can read here(link below) the S-200 Vega site located near capital city Prague and nicknamed “Klondike” had three launch areas with six launchers. The main storage area contained 34 pcs of the 5V28 missile in containers, two missiles were permanently kept in alert status. With proper storage maintenance the missile lifetime is about 20years, but once the missile was filled with high aggressive fuel compounds, its lifetime droped rapidly. The missile had to be emptied imediatelly when alert warning went off. After five years these “worn out” missiles were sent to Kapustin Yar for live fire excercises. In late 80ies one 5V28 missile cost about 8million Czechoslovak krones. Because of these reasons only 2 missiles were filled and kept ready to launch during peace time.
    The whole S-200 site lifetime was estimated between 30-40minutes during a war, what is discussible since NATO already knew the site location, thus expecting they would strike it quick. However, it was assumed the site will launch the whole package of missiles stored (36 pcs total).

    What about a second location …., or a location inside Slovakia?

    It was simple, after Czechoslovakia split in 1993, Czechs kept the stationary S-200 sites and Slovakia got the single S-300PMU package with the 5V55R missiles.

    That I couldn’t tell you. How big are those? They do mention the size of the hole it made.

    The SA-2 warhead is made from a steel with grooved surface, the blast creates around 7000 steel fragments with size of cca. 2x2x2cm.

    P.S. The following picture describes US recce missions over North Vietnam, the dashed bold line depicts first SR-71 overflight, (t=10min)
    The book I was recently talking about admits the Vietnam SA-75M Dvina being short to attack the SR-71.

    I’ve just been digging around the CIA’s FOIA website, and there is a lot of stuff in there on the OXCART flight, BX6734, when they found the SA-2 fragment.

    How the SA-2 fragment looked like?

    Similar to this?

    Martinez, that link on Czechoslovakian SAM sites is outstanding.

    I thought it will be interesting for you. The website is written by ex-PVO guys, so hopefully you can navigate, read or translate…:)

    some other post-war PVO sites…

    No it doesn’t, they flew within DDR and WarPac S-200 range all the time during the Cold War.
    .

    The SR-71 kept a safe distance away from WarPac state borders, so describe it as a combat zone is a bit strange. We knew the SR-71 is flying its “harmless” recce mission leaving the S-200 sites cold, no preparations for launch or set the S-200 missile on the launch position.

    Only one small part. It didn’t cause any damage, it was just lodged in one of the corrugations on the undersurface of the wing.

    A small part made of light alloyed metal from missile body doing more than seven thousand steel fragments comming from the warhead shell after detonation. Very interesting story indeed. :rolleyes:

    Where did I say the 123k flight was a standard flight?

    sorry, just stating the facts…

    I’d read the Mig that hit 123k used it but I didn’t know it was standard issue. Kindof a kludge for the envelope the Mig typically flies IMO.

    …not a standard flight, it hit the altitude 37650m only once, what is 123523.6ft.

    The info on the jets converted to MiG-25M testbed standard came from the recent Red Star volume on the FOXBAT family. Does anyone know what altitude the jet tracked at M3.2 was flying at?.

    R.Belyakov predicative statement on the Mig-25 exceeding M3 speeds…

    As a matter of fact, the speed limit of M=2.83 on aircrafts Mig-25 was just theoretical. On higher speeds of flights the directional and lateral stability was reduced as well as the aircraft structure life-time, but in some cases pilot exceeded more or less the number M=3 without negative effect on the aircraft.

    Of course, this statement of the OKB MIG designer should be taken with a grain of salt, as he ommited the inlet air stream and aircraft structure temperature limits, which showed pilots to slow down. Although, speeds beyond Mach3 were possible with the Foxbat if everything went right .

    P.S> thanks for the info, I`ll wait till some good souls scan the B-70 book and put it on the internet.:)

    It was the Blackbird’s J58 that often encountered unstarts, not the J93, but it had nothing to do with the engine and everything to do with the intake system. .

    It has indeed, to do with the J-58 engine. The unstarts were caused by compressor unstable operation (stall) what resulted in a loss of compressor/engine performance, caused either by failure to maintain proper inlet operation or compressor active control. The difference between both engines is that the J-58 was more susceptible to engine unstarts due to the 9-stage compressor with much higher compression ratio, what needed complex active control(bleed system) with precise intake operation to ensure the stable operating region of the compressor, whereas the R-15B-300 was relatively immune to unstable compressor operation due to very low compression ratio of 4.75.

    I don’t think so, and I think I know where the confusion stems from. There was one MiG-25P and three MiG-25Rs that were refitted with the -300 under the MiG-25M test program. One of the R models refitted was one of the jets that had been deployed to Egypt. .

    I;m sorry but the article doesnt provide further explanation. What if the MiG-25R which was tracked flying over Israel at Mach 3.2 was indeed the one fitted with the R-15BF2-300 engines.;) Very good assuption, but do you have any proof for that, or is it just your personal opinion?.

    P.S> Could someone provide details about the J93, no luck to find any good links

    According to the information / declaration I’ve gotten, at least the manufacturers (or pilots) of Rafale, Super hornet, Flanker, and Fulcrum all declared that their fighters could achieve the maximal roll rate of 250 to 270 degrees / per second.

    damn, would like to have your sources at Mig and Sukhoi…..:D

    only f22? could you give me an official doc to prove it? thanx in advance

    DOZER said that, are you deaf? So it is official, no need for further proof.

    I did mark in bold letters for all to see. I am still in wait for your sorry, my fault or error and no further twisting. :rolleyes:
    You claim the Russian issue of Belyakov, so you can not have missed that too!

    geeez….I will repeat it again for you.

    I UPLOADED BOTH PAGES FROM THE BELYAKOV/MARMAIN BOOK, SHOW ME WHERE IS WRITTEN ABOUT THOSE SEVERAL MIG-25RB EQUIPPED WITH R-15BF2-300 OR AT LEAST WHERE THEY CLAIM ABOUT SEVERAL EXPERIMENTAL VERSIONS WITH R-15BF2-300.

    The text content in the French, English and Russian book should be almost the same, so I do not believe what you fabricated in last seconds and then marked with bold.:rolleyes:
    I`m also waiting for sorry for this lie….:D

    the R-15BF-2-300 were used for record examples only
