Lock a jamming target, and the jamming noise fills the central stripe of your radar scopes. Launch a missile. The missile is not visible if it's over the jamming noise stripe.




Why do not use BUG topic? screwy

Yes, it is an AS optical tracking from unknown S-125 modernization...

Found the bug, and will be corrected in the next release.

Its fine.
AAR do not shows the real target data, instead of what the system calculates.
As I used only KARAT and TT method, I simply left the range mark just a bit closer than 40km.

The S-125M missile was a normal target few years back in Ashuluk, so shooting it down is not impossible...

I have a query concerning the maximum range of 5V27U and 5V27D missiles. After extended testing I ended up with the fact that missile's actual maximum range is about 22km only against high altitude targets. Usually the longest range kill can be seen in the middle of the 20-25 km area in range indicator of the fire control panel as seen below.



However the displayed range in fire control panel depicts the length of a "line" which connects the fire control radar with the target, right?

Therefore the instrumented range is different than the horizontal range right?

In the plotting board screen where the range ring (maximum horizontal range) of the battery can be seen, I calculated the radius for S-125M1 which is about 22km.

A simple graph could be like this:



Normally the maximum range should be higher than horizontal range as the hypotenuse of the triangle but in many cases their values are very close. Why this happens?

Many sites state that maximum range for S-125M/M1 is 25km. Is this the instrumented range or the horizontal range?

Additionally I haven't seen any differences between 5V27U and 5V27D in terms of range. They seem to have almost equal range.

Been using the 125 in SamSim for a few weeks now (along with all of the simulated systems apart from the Shilka) And only now have I realized that it doesn't have an indicator to show the elevation of the antenna array...

Or at least I have not noticed it yet since I haven't looked too closely at the panels...

The rightmost (Vc, R, Hc) instrument below the indicators shows real elevation (in Km) instead of elevation angle compared to Dvina/Volhov.
(seemed to be a good idea during Neva development, to make the Fire Control Officers life easier)

IMHO its a bit confusing arrangement (I would have swapped it with the Vc indicator).



S-300 went back to the original way, and again it shows elevation in degrees instead of Km's...
... so again you have that ugly elevation-range-altitude table, you can find between the indicators of the Dvina.
biggrin
