And Krug against U-2 :-)

congradulation

A bit too much transmition, but still good job...

About my beloved "Volkhov":

I am sure that "Rab ot VM" works even after missile is launched:

Shortly, if we do not know the height when using TT I-87B, K3 and K4 depended by switching of the "Rab ot VM" switch.
If we switch it BEFORE launch or before 18-th second after the launch (11-12 km of the missile flight), K4 goes to missile on the 18-th second, and K3 on the 22.6 second of missile flight.
If we switch "Rab ot VM" after 18-th second of the missile flight - no K4, and K3 is transmiting on the 22.6 second, or in the moment of switching!

If K4 was transmited (switching "Rab ot VM" before 18-th second)- it tunes radiofuse for missile-target relativ speed 750 <V rel < 1750 m/s.
If K4 wasn't transmit at all (switching "Rab ot VM" AFTER 18-th second) - the radiofuse antenas are tuned for relative speed above 1550 m/s.
So if we do not know target speed or it's a high speed target, we should switch "Rab ot VM" after more than 18 seconds after launch.

Also for the VOZVRAT option:
From Hpasp:

If VOZVRAT is presse before 23-d second after launch, but before pass the range boresight the missile selfdestruct right after 23-d second from launch. if VOZVRAT is pressed after 23-d second from the launch, but before cross the range boresight, it destructed almmost imediately.

Why a bit too much? Transmitter is at EKV until 7:19, then on for 24,5s (I admit I should switch it on when the antenna is pointing at correct azimuth), on at 8:04, off at 8:18, on at 8:35 and the engagement begins. Total airtime was 1:51 and could be lower by 23s because of educational purposes - after shot down I showed indicators going down.

No offence, man, I stay even more "on air", but Zoltan's crew searched not more than 10 sec, and engaged not more than 20 (which included 10 sec. searching).

The U-2 was my first try with a 2K11, so here is a revided (and hopefully better) version :-)

I understand we are doing work for many people, so we can't be so fast, but from PUSK press to the first hit it takes nearly 30s ....

And finally: you must not forget I am not an expert with S-125. Not even close to Zoltan and his crew

Can I share this video on the SAMSIM website?

why sa-6 missile armed with 4 air inlet ???? sustiner sa-6 missile is ramjet?????

Yes, you can of course :-)

LEGO KRUG...

Yes, sustainer is solid ramjet.

GREAT!
I wonder where he got pieces to build it....

This isn't the first time that a SAM has out-performed its stated capability. This happened in the falklands as well. There is more to a SAM engagement zone than just rocket capability.

Actually the borders of the SAM (guaranteed) destruction zones in the Soviet systems are not like hard walls.

They just state, that inside this zone, the missile will kill its (non jamming, non maneuvering) target with 97% chance.
Outside of these zones, the chance of hit will be dramatically reduced.

Even the official firing manual states some case, where missile should be launched while the expected destruction point is outside of the guaranteed destruction zone.

Yep, I figured it was something like that

Just some additional info, to help the brainstorming here...
Contrary to the RPC 1.4 or 0.7 degree beam, its IFF system has a whooping 10 degree "pencil" beam!!!
If the target is inside of it, giving "I'm your target" signal, the crew could accidentally lock on target, 60km away from the actual IFF signal sender.

This is why own fighters should stay far away of any S-200 engagement.
(See piston table above.)


WARPACT procedures called several IFF checks during an engagement.
1st check after target acquisition.
2nd check just before missile launch.
3rd check during missile flight.

My guess is the crew did several IFF checks on the passenger plane, just the drone was inside of the 10 degree area...
