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.

Yes, that's it, but in that case I can swear that on 923.0 (and maybe 932.1 and .2) it wasn't 4 degrees it was less... And I was so unpatient with your answer, because it was the essence of my "How to cook Habu for 10 minutes" cookbook. You swear you didn.t touch anything? confused
Also, I've noticed that when shooting against reflector on Ashuluk, on UPR or K mode, missile didn't jump to 4 degrees mark on the screens. I've tried with AS on epsilon and beta only, seems to me it doesn't have any diference. Even when put distance boresight far beyound the target it seems that missiles adjust their way to target path, no matter that target is not tracket on distance, and often didn't stick to 4 degrees mark (when the target is miving fast missiles goes to 4 degrees mark, there is something with speed). I've experimented on Hungary and Ashuluk, and that's what I've observed... Something is different... screwy

In favor of the Dvina rise of 60 degrees is the limit.

75 degrees only against the ADA.

80 degrees and more than just Dogon!

This is so or not, I saw a map in the diagram 60 degrees was the affected area, 75 for the ADA.

In the Dogon limit Speed of Target V(t) <= 420 m / s

Clearly too soon.

Definitely there is a diference in missile behaviour between 932.1 and 932.3 versions.

923.3 seems to be the correct one.
The target is far away (over 75km), so in epsilon, the missiles has the maximum elevation for method K, and in beta maximum UPR.

Hmmm, and you said "No change in missile behaviour" - little sneaky developer... biggrin
Anyway, the + 4 degrees is depending from distance, what else have "Dvina"/"Volkhov" in mind, when determing the degrees of UPR. Speed?
If the target is not tracked in distance (which ussualy is not possible under jamming), thus moving of boresight closer or further has no effect.

The question of why the CP-71 You Set the "K"

SR-71 High-rise and high-speed target and interference, why the "K"

Need T / T?

It is not clear to me!

Question about Hpasp!

I noticed a feature that has long Volkhov Line range can be extended only to 140 km and 150 km are not!

But while the Dvina on a Maximum of 110 km.

Why this is so, it is this feature or not!

You can move to the Volhov range bore-sight to 140km maximum.
The impulses sent out using two period (1044 micro sec for 140km, 1132 micro sec for 150km), and displayed till 150km.

You can move to the Dvina range bore-sight to 110km maximum.
The impulses sent out using two period (110km, and 120km), and displayed only till 110km.
The range between 110km and 120km is simply not displayed.
