One thing I'd love to see is how each of the systems modeled in SAM Sim would do against a helicopter. If only this could be developed as an expansion to DCS world, then it could be!

Here is the part of the war journal "Smena", written by Lieutenant colonel Djordje S. Anicic, where the discovery and shooting down of F-117A nighthawk are described translated to English.
Saturday, 27.03.1999.
There are no close targets in the air. There are plenty at long ranges, and different azimuths. Major Stoimenov gets up so I can sit, hands me headphones for communication with brigade command, and moves behind FCO. Rest of the men are at their places. My men. When Dani leaves in just a moment, I will sit at the place of launch handler*. By habit, Dani and I exchange information about latest events in the unit. In short I tell him what I did that afternoon, and he tells me, still napping, what he did. Radiation imitator is still not connected and ready ti work. Suddenly on the screen of observation radar, on azimuth 195 i spot a target at the range of 23km. Next sweep on the radar screen clearly shows that the plane is approaching us. I say: "Dani, this one is coming at us!" Dani opened his eyes, looked at the screen and uninterestedly followed the situation. Reflection was closing. Plane was at 14-15km, when Dani ordered: "Azimuth 210, search!" As assistant launch handler, at that moment I ordered: "Antena!" Battery commander started guiding tracking officers to the target - left, left:stop!, right, up, up:stop! - antena. He turned on radiation of the SNR. At that moment begins the game of cat and mouse. Who will be faster and more skillful. FCO, while turning three wheels at the same time, tries to acquire the target. SNR is on for more then 10s, and unsuccessfully searching the target. I order: "Stop searching - equivalent!" After several moments, Dani again orders new azimuth 230, and I moment of radiation. Adrenalin can be felt in the air. This time FCO manages to see the target on his two screens, but cant align it with horizontal and vertical markers. Wheels are clicking - he has to push them away from himself, align the target in intersection of these two markers. At the moment the target is in intersection of the markers, manual tracking operators can start tracking it in f1 and f2 planes. Then conditions for FCO to track the target in range and manual tracking operators to guide the missiles to the target in the crosshairs. Target is running and maneuvering. Again, radiation time is too long and I again order: "Stop searching - equivalent!" After a few seconds we try again, third time at azimuth 240. Very quickly, after a few seconds FCO finds the target and reports that the target is maneuvering. FCO wheels are clicking, operators are loosing it. Time of radiation is again too long and just as I was about to order: "Stop searching - equivalent!", tracking operator Dragan Matic yells: "Come on! Come on! I have him!" Frantically turning his wheel, he tried to get the reflection of the target to the middle of the screen. He made it. Tracking officers managed to align the target with the crosshairs, and met the conditions for the launch of the missiles. Second tracking officer Dejan Tiosavljevic reports that the target is of a large radar cross section. At that time I say to Dani: "Be sure that it is not a decoy." I think of war experiences in Iraq when the allied forces mounted corner reflectors on UAV-s and increased their radar cross section. Iraqis thought it is a real plane and started to radiate with their SNR. At that moment fighters in the air caught the locations of SNRs, and then from hiding on the side eliminated Rocket unit with ARMs. FCO Muminovic reports - SNR tracking the target, target approaching, range 13 kilometers. At the same time operators report - on f1 tracking target, on f2 tracking target. Dani commands: "Destroy target, method t/t, launch!" FCO Senad Muminovic presses the button to launch the rockets. Loud explosion. Booster motor of the first rocket screams. Rocket guidance station** rocks. First rocket starts, and after 5s the second one. FCO reports: "First launched, first acquired (tracking operators start guiding the missile towards the target), Second launched, second not acquired (unable to guide the second missile). Range 13 kilometers." Operators in f1 and f2 are tracking. I get up and watch the last kilometers of the rocket flight on FCO screen. At the point of collision a light flash on the screens is visible. Target destroyed. Time of destruction at 20.42. We found the plane at 6km altitude. Plane maneuver to avoid the missile and is hit at about 8-10 kilometers altitude. FCO did not readout other parameters, all happened in a few seconds. Entire process lasted about 23 seconds. After that panic in the air - nowhere not even one target. At the command headquarters of 250. missile brigade Major Janko Aleksic, from the technical department. At his request I dictate the composition of the team that shot down the plane. Dani commanded only guidance method, and now I cover him and as per regulations I report way of the launch***, expended rockets, activation method of warhead, basic parameters of the target. "Great work, legends!" slipped from Major Aleksic.
-----------------------------------------------------------------
*launch handler - This is the commanding officer of the fire team. **rocket guidance station - This is the trailer where the fire team is located. ***way of the launch - I'm not really sure what this is, it might be guidance method.
Even if it might not be fully correct word for word. I did my best and I hope you can at least get the essence from it.
Happy reading!
p.s. Also note that I did not translate the entire day described in the book. There was alot before it happened, and after. But I concluded that it was irrelevant and that nothing translated is out of context. Oh and about that where I said Dani was napping.He wasnt napping as in sleeping. He was just tired after his 8h shift and was too relaxed while nothing was happening in the air. This is not as bad as sleeping, bud still dangerous when you are in command of a Neva.

OK, Uncle Vintorez hits the Vega! 1) Case: you launch missile without a GSN lock. Provided that no lock was obtained at all, the missile is lost always after the same ~60 km of initial flight, and that irrespective of its initial trajectory (low-alt, for close targets, or hi-alt, for distant targets). What is the reason? At least with hi-alt, the missile should have fuel / kinetic energy to cruise much longer, and drag should not be the issue. Auto-destruction triggered by some "KRO-too-long" stuff, or what? One of the major advancement, of the S-200V Vega (SA-5B) system compared to the S-200A Angara (SA-5A), that its missile is keep flying to the previous direction, in case its GSN lost its target track. When a missile of an Angara system lost its track, the missile was simply lost. The Vega missile is capable of reacquiring the target during flight. What happens, when you launch without lock? The missile will keep its original direction 48 degree elevation, until GSN lock. 2) Hpasp, you said once that increasing reflected signal strength while the missile-target distance is decreasing is fully modelled so that the missile can catch the signal in flight even if its strength measured at the radar remains the same (I mean, too low for LOBL). Is it really so? I haven't observed such effect even once, and I am sure there are at least several situations when, if modelled, it should bring a kill.
Problem (might be) is that we are not talking on linear units, rather logarithmic decibels. 3) what is the difference between incoming- and receding-target related settings at GSN? Does the missile fired at incoming target with "incoming" GSN setting have a chance to continue track after target turns? In Ashuluk, I managed to kill an incoming target with V<0 setting without any problem. As far as I can remember, in combat scenarios it makes no difference too.
There is no V<0 GSN setting, its just a subversion of "acquire after launch". 4) Is it possible to see your missile on your Square Pair display? If range screen gives you some idea about group targets, I wonder whether the hit (at least target echo growing for a short while - or blinking - when covered by splinter cloud from a close explosion) should't be visible too? The same with HARM launch from a tracked target (e.g. a speed strip splitting in two, and the latter accelerating before lost from the screen)?
Splinter cloud is not modeled with the Vega. Missile could be visible, just do not forget, that it flies away from you at high speed.

So, RV-SB is low altitude fuse, RV is high altitude fuse, K3 is automatic destruction of missile by the system. And RV and RV-SB both arm the missile straight after launch? They just have different fuse sensitivities, correct? They are mostly the same as we have with the Volhov, the difference, is that the Neva can select them automatically. Neva / Volhov RV / STAN RV-SV / USU-NLC K3 / K3

Hah! Another basic question of S-125, how many degrees does it scan in azimuth? It is not in the manual. This is when the S-125 is in non-tracking mode. I mean the beam of the radar 1,5 degree

Hpasp,about the Vega, can I ask what the range is before the missile is incapable of achieving lock? Is it ~60km as vintorez stated? No. When the missile looses its track, it will continue its flight straight. It will be lost, when it flies out of its effective envelope.

dear gray ghost .. im not mr.hpasP but......... i read about this senario! im sad about his happend i dont know why sam crew dont use IFF system! tracking unkown target without IFF Was a big mistake! also this is not only happend! around 1980 or 1990 one uss navy (vinesens) tracking and hit one airbus number 655 with 2 missiles (standard missile 2) and after report action them cll'd ooo we hit f-14 ! and then after pass few houre they understand that hited plan is a civil airraft with around 200 passenger! Hpasp, would you have an opinion on the Air Siberia shoot-down by Ukrainian SA-5?
