I stand corrected PLCC smile In comparison do you know what sort of target the SA-3 was primarily designed to defeat?

The SA-3B S-125M Neva standard missile (V-601P) has overload capability of 14~2g.

Do you mean an overload capability of 14g to 2g (low speed high alt) or 14.2g?

I mean an overload capability of 14g to 2g depending on several factors.
- missile weight/distance from launcher
- missile speed
- missile altitude
- second stage active/passive state

like this...


14g is at around 7-12km distance, 0-3km altitude
Green line is where the second stage burns out (21.2s), from there the missile decelerates.

Missile speed is depending on flight time, and flight elevation.



This is what the next release of sim will contain thumbsup

Are you sure you wish to use data from old, slow missiles?

Thanks Hpasp, that's great news smile
I really need to learn Russian.

Yes. yep

5V27D (V-601D) become available only after the Cold War.
Before '99, everybody used the V-601P, (-PU, -PD, ...).

I heard rumors, that the 5P73 could handle only 3pcs of V-601D, as those weight is higher.

Guidance method KDU is used in your graph.
Also it can be seen, that the first stage accelerated the missile to lower speed (500m/s compared to 600m/s) due to the heavier second stage, that achieved higher top speed. (1000m/s compared to 900m/s)

I can confirm, that following your proposals, the next version will contain the possibility to select between the following missile types...

- V-755 20DSU or V-759 5Ya23 for the Volhov system.
- V-601P 5V27U or V-601PD 5V27D for the Neva system.

These missiles should perform within 1% of the original firing range data...
