A few Questions for CMBS

[Stagler]

T50 has great big heat-bleeding and venting unsheathed engines, just like the F-35, so I think we are in the same boat.

The point is that ELINT sensors (and ARM's passive seakers) detect side lobes, as the main love is very thin. Because modern radars have considerable sidelobe reduction measures installed the power emitted via those side lobes is far less than via the main lobe.

As Gazetchik emulates the side lobes of a given radar, it provides the active signature that is exactly the same as of the radar it is set to emulate from the point of view of an ELINT sensor or ARM seaker. Morever Gazetchik could be connected to the parent radar to have a synchronised cycle of emition.

The operating cycle of the SAM system (shoot-move-shoot) does reduce the amount of time a given system works, that is true. However considering the fire productivity of modern SAM designs (multichannel architecture) and amount of HIMADS likely to be employed in such a conflict the amount of engagement channels available (at any given time) would be sufficient to engage all hostile platforms in the air (at the same given time).

jammers just have access to more power.

Recent intercept for the S300V4 test against low RCS target occurred at ~400km range.

 

Guys who design ELINT systems are not stupid, the system's is meant to be used against sidelobes but if radar illuminates you with it's main lobe (which it will since it must search for targets) you can then discriminate it from any decoys. 

 

How many systems do expect to be deployed?

 

It's not just about ERP. Other things need to be considered as well, like elevation angle of the radar, amount of standoff the jammer has from what it is protecting, etc.  

 

According to USN RIM-176 has the record for the longest surface-to-air engagement and RIM-176 is not capable of anywhere near a 400 km engagement (simply too small).

Or it won't as it's sector of responsibility doesn't cover that specific airspace (that you are flying in).

 

Hypo-theoretically? 4 Brigades means 24 divizions or 96 fire units of S300V4, which in turn have around 564 simultaneous engagement channels between them. In radar, within the S300V4 forces, terms:

- 96 multirole radars.

- 28 high power ABM x-band radars.

- 28 general purpose search radars.

- 4 mobile UHF/VHF radars.

 

Well, the "Giant" round with the improved fuels and guidance package (with trajectory improvement) gets you that kind of range. Note, 250km class range is nothing new really, S200 had that long time ago (Ukrainian S200 round shot down an airliner over the Black sea by a accident a decade ago or so I think), as do the new S300P series rounds (such as the 48N6DM).

Not sure of the distance to aircraft, but yeah actually a little more than a decade ago.

On 4 October 2001, Tu-154 crashed over the Black Sea. The plane was hit by S-200 surface to air missile, fired from the Crimea peninsula during a Ukrainian military exercise.
