Can Anyone Help IDENTIFY This "SOVIET" Rocket ?
Can anyone help identify this "SOVIET" rocket ?
There is "B-625" associated with drawings of the prototype, but the search to accurately identify the rocket is still ongoing. Please feel free to post any information / data ! Dave F. Last edited by Ez2cDave : 06-10-2022 at 08:59 PM.

The first photo shows the vehicle on what appears to be an SA-2 launcher - plus there are SA-2 blast deflectors to the left. On the middle (cutaway) photo - is that a warhead toward the nose? I'm thinking this was a prototype SAM and not a sounding rocket. Plus B-625 is Cyrillic, so it's actually V-625. Lots of Soviet SAM SYSTEMS were designated V-XXX (though the missiles themselves were often S-XXX).

Well,
I've never seen this one before. It's not particularly large. Overall length is 318.9 inches or a little over 26.5 feet. Booster diameter is 17.71 inches and sustainer is a bit over 11 inches. It bears more than a passing resemblance to an early model Terrier missile. With those large fins, this is definitely not a "SAM in a can" as the Russian armed forces seems to prefer today. My guess would be this is an older design from the 60's or 70's. Overall, I'd classify it as a Standard EM analog. Dave, where you got the drawing, picture and cutaway can be a clue as well. Where did they come from?

Mark, Well, I could tell you, but . . . LOL ! https://forum.dcs.world/topic/28198...d-of-the-r-27er In that thread ( unrelated to the data in question ), about 2/3 of the way down the page. The person who posted it just referred to it as "an old Soviet project". He used it as a "reference" for their computing velocity for an R-27 ( totally unrelated ). Here are ALL of the images ( below ). Dave F.

I just ran the dimensioned drawing and the "chart" through YANDEX, for translation.
Here are the results . . . Apparently, it's called a "V-625" . . . "Obozi" . That, unfortunately, yields more "dead ends". Dave F. Last edited by Ez2cDave : 06-12-2022 at 01:51 PM.

I have discovered some additional information . . .
The "B-625" ( V-625 was an early version of the S-125 ). YES, it was FLOWN ( pics below ). This a a large "DJVU" file . . . https://disk.yandex.com/d/NVDypORSA2qd7 This link will allow you to convert the DJVU file to PDF format. https://djvu2pdf.com QUOTE : It's an S-125 variant. Undeveloped prototype. https://historykpvo-2.ucoz.ru/index/0-13 From the book of Mikhail Pervov "Anti-aircraft missile weapons of the country's air defense": The missile under the index 625 for the 125th complex was developed in the design bureau under the leadership of M.G. Ollo. In the design of the rocket, a solid propellant sustainer engine was used for the first time. Station tests and autonomous missile launches were carried out in Kapyar. Difficulties arose at the stage of complex testing. When launching missiles, it was not possible to get into a given sector of the radar - each time the rocket left the given point for a considerable distance. Conducted ten unsuccessful launches. For a long time they searched for the cause, but did not find it. The situation was getting critical." The experimental sample included a missile guidance station with an antenna post, two-rocket launchers and a 625 solid-propellant rocket. Tests of the guidance station went well. However, missile tests have stalled. At the very first launches of the 625th rocket, we encountered an incomprehensible phenomenon: the rocket constantly left the sector of responsibility to the left. We tried many options to keep it in the sector: we put mechanical programmers into the system of control commands, carried out all kinds of manipulations with the angles of shooting into the sector ... Nothing helped! Not a single firing in a closed control loop could be carried out. The missile was returned to the factory for revision." In 1959, Ollo brought several modified rockets to the test site. As it turned out, the reason for the unsuccessful launches was simple. On the drawing of the docking cone of the first and second stages, the vertical dimension of the cone was indicated on one side as 558 mm, and on the other side as 553 mm, although both dimensions should be the same. Someone, by mistake, wrote a three instead of an eight, as a result, the cone turned out to be "curved" during manufacture, and the rocket - "curved". The difference of five millimeters was not noticeable to the eye, but invariably manifested itself in flight. This insignificant oversight led to the failure of the tests. The work of a large team of designers, workers, testers and huge material resources were spent in vain.'' END QUOTE : Dave F. Last edited by Ez2cDave : 06-20-2022 at 08:24 PM.
