Hi all, does anyone know how many G's could missiles used in SA-2B,C,D,E & F systems pull during turn? 3G? 5G? They were quite heavy beasts so I guess they weren't very good against maneuvering fighters? Thx!

question to dear hpasp

in vietnam war and other scenarios i didnt see any coefficient of error of missiles as a realistic to switch object on samsim

i can launch one missile of target and before it !
i am pretty sure ke target will destroy by my only missile that launched by me !

would u explain to me about this realistic object ?
some where you wrote with launching 3 dvina missiles you have 96% to hunt the target
but with one missile....our 96% have to Division to 3 = 32% !!!!

so how with 32% we can hunt all of targets in vietnam and others like libya and allied forces scenarios
with one launch one kill ?

Probability calculation is a bit more complicated than simple division wave

But when assesing of missile performance it is even more complicated. We have flying objects with many degrees of freedom, they are doing manoeuveres and so on. It is not so easy.

And I am pretty sure that the probability of target destruction is found out empirically - from experiments and statistical analysis of measured data. All those sigmas, correlations, variations and so on.

OT, I quickly looked at wikipedia and there is central limit theorem, this I had at exam of mathematics 4, which was focused on probability and functions of complex numbers. And I could not remember it and make a mathematical proof of it sigh

Nice link Hpasp

"Since the Shrike's introduction, the percentage of SAMs fired with radar guidance has been greatly reduced. The far greater number are fired in salvo and are unguided because the ground sites cannot afford to stay on the air. This has greatly reduced their effectiveness and has been a big boost to the morale of the strike pilots. It should surprise no one that an increase in SAM firings and an increase in Shrike firings occur at the same time. Most Shrike launches are the result of SAM activity and launch warnings."

I guess this is the SAM sites switching on the missile command transmitter, without launching a missile?

Hi, guys.
I have a question about S-75M Dvina.
Situation: I find a target, get it tracked in "PC" mode, then I switch transmitter off on block I-66 (However the load is switched to Antenna, not dummy) - target diseapers from I-32 beta-epsilon monitors (target is not jamming), but the system is still tracking it! Indicators on the I-88 block still show changing parameters of the target! I can even launch rocket and score a successful kill! How does the system track target without emmitting signal? confused

I think it's supposed to represent your crew maintaining a constant rate of rotation, elevation and range change, predicting where the target will be. Though I agree it sometimes seems a little too accurate.

But, I could be wrong.
