Dear Hpasp,

About 3D AAR - it is certanly a step forward. As we know, a lot of tests in Ashuluk were traced with telemetry, so why don't we haven,t one? Vintorez gave even better idea - to include the data from SAM kiling zone in that picture. I thing it's still "realistic to the switch" and also helps to us to have data, which was "downloaded" from military during real test shootings.

What is your plan - to have this AAR only on Ashuluk and Ustka, or even for historic scenarios?

Im just playing with this idea.

If I do it, than it would be done for all scenarios.
(I have no idea currently, what load would it cause at the Hanoi Scenario, where 120+ planes are around...)

Have you tracked your missed shots by your P-14 radar? They often fly far enough from the target to be noticeable there. Here's my AAR:

Asuluk training ground.

Practice target:
RM-217 Zvezda [program-3] simulating F-117A Stealth

S-200VE Vega-E


00:30, Practice target RM-217 Zvezda [program-3] simulating F-117A Stealth launched

19:11, Missile launched from launcher-2
Target distance: 41km
Target azimuth: 80°
Target elevation: 19°
Target angular speed: 677m/s (2,4 Mach)
Target altitude: 14km
RPC mode: MHI - Narrow Beam
GSN mode: Acquire target before launch
Received signal strength: 25,7dB


19:18, Missile launched from launcher-1
Target distance: 37km
Target azimuth: 82°
Target elevation: 21°
Target angular speed: 624m/s (2,2 Mach)
Target altitude: 14km
RPC mode: MHI - Narrow Beam
GSN mode: Acquire target before launch
Received signal strength: 27,5dB


19:43, Missile exploded
Practice target RM-217 Zvezda [program-3] simulating F-117A Stealth hit by SAM. (miss distance: 280m)

19:48, Missile exploded
Practice target RM-217 Zvezda [program-3] simulating F-117A Stealth killed by SAM. (miss distance: 35m)

Total, SNR On Air Time: 2min 1sec


Very interesting AAR, thanks for sharing it Lonewolf!

This is IMO getting really and even more wierd. Yes, it's noticible that the proximity fuse worked at a distance of 280 meters which concurs with what Hasp said: The Vega has a proximity fuse that detonates at distances up to 300 meters - At least this is a very good news!
But what's still wierd is by reading your AAR that your shoot parameters are not diferent than what I usually do in the shooting range (and I never got any proximity detonation at longer distances, like you did). Also you even use the suposedly "less precise" MHI RPC mode which I also often use but somethings I also use and tested the other suposedly more precise mode (called FKM or something like that - sorry I'm not at home to check the name of this mode wink ) but with the exact same results!

Regarding your question about tracking the missiles using the P-14 radar, NO I admit that I often do not use it to track my missiles (only rarelly I did it) but that's a good sugestion and I will definitly take a better look into the P-14 not only to search for my targets but also to track my missiles.

So and according from what I've experienced coupled with you AAR I still think that maybe there's something wrong here (but I could be wrong thou as I was before) but now I'm convinced that the problem doesn't seem to be related at all to the proximity fuse, like I previously suspected.
I now suspect that there's something wrong with the proper missile behaviour (it's flight path and precision). And here's why I have this oppinion:
1- Aparently there's nothing with the missile's fuse (great news and I'm glad that I was wrong regarding this)
2- But IMO, it's still strange that the SA-5 missile either passes VERY NEAR to the target or VERY FAR from the target (more than 300 meters so that the fuse won't work) and there's no "MIDDLE" distance passes at all! I think that my experiences seems to somehow confirm that the missile either passes VERY NEAR (less than 18 meters) and yours also confirm this (detonation at 35 meters - longer than what I've experienced but still relativelly very close) or that the missile passes VERY FAR from the target since from my experiences I never got a long/longer distance detonation and your experience shows that you distant detonation was in fact VERY FAR - 280 meters which is almost outside the 300 meter fuse range.
3- So if Hasp decides to reduce the 300 meter range fuse, you would basically end up with exactly the same experiences that I get with the SA-5 since the first missile (280 meter) would never detonate and the other is a rather very close detonation/pass (35 meter).


So and resuming, could there be something in the simulator code that either makes the SA-5 missile to either pass VERY NEAR or VERY FAR from the target with absolutelly no "middle term" like for example 100 meters?

Hm, Hanoi is tough job... Maybe it's good to pull down data only for target which are fired against. Even if it doesn't load too much the sim, all 120 target could create a mess in 3D AAR (like they allready do on plotting board).
But if AAR presents the path only of killed, or fired against targets, how could pick them from all? we could fire (with SA-2's) against target which are not tracked at all (but still must be tracket in any dimension at least for a while), so maybe this could be your rule for selecting from a list. Of course if it is posslible to put this kind of selection.... yep

Hm, I have something like that in mind about SA-2's, because in ver 932.3 missiles had different behaviour,( I've wrote about it), but Hpasp told me that everithig is fine...

Maybe you're a sharpshooter ;), so lay back and wait for 3D/AAR thumbsup

Yes, I understand that the fuse behaviour was somehow changed with the newest version (923.3) but even so with this latest version I still can get proximity detonations at distances of for example 60 to 120 meters (or less and sometimes even higher distances) with both the SA-2 and SA-3, situations that I cannot experience with the SA-5 and this really puzzles me...

The 3D/AAR is definitly a great addition to this already great sim thumbsup

No,no!.. I wrote about missile behaviour, not for fuses, fuses are reseted, as I asked Hpasp long ago... Check this post:

Nothing.

If there are changes, please, describe them, because It seems to me that missiles do much more UPR than before (say ver 923.0)???

Shouldn't be over 4 degree.

Definitely there is a diference in missile behaviour between 932.1 and 932.3 versions.
13:45 19th of December, 1972.
SR-71 bomb damage assessment flight number one.
Battery 261/57.
923.1:

923.3:



That's for what I am talking about. Completely same situation, total diferent behaiviour (see where are missiles marks, compared to the epsilon and beta boresights).

It's not released, yet.
