Irtysh ECM system on Su-25T

[4c Hajduk Veljko]

One Frogfoot book that I read claims that Su-25T has built in “Irtysh” ECM system that will automatically control chaffs and flares dispensing.

 

What we have in Flaming Cliffs is a MPS410, Omul ECM pods. These pods were designed to be installed on Su-25TM (Su-39).

 

What is the deal here?

[GGTharos]

The deal is that the CMS (Counter Measures Management System) is a different system than jammer pods, but all fall under the category of 'ECM' in one way or another.

 

CMS is not implemented in FC, quite obviously.

[Shepski]

I believe "Irtysh" is just the ECM component and the programmable chaff/flare system is separate.

 

The Ka-50 has the UV-26 programmable flare defense system for example.

[Force_Feedback]

no chaff on the ka-50?

 

good, now we'll have enough flares instead of a crapload of chaff which you can't use up in one sortie.

 

any good reads on the ecm system?

I believe "Irtysh" is just the ECM component and the programmable chaff/flare system is separate.

Irtysh is referred to as the ECM system with capability to automatically dispense chaffs and flares.

 

While MPS-410 is probably more advanced ECM system, it requires several hundred kilograms worth of pods to be carried under the wings. With advanced flight model of Flaming Cliffs that weight and drag reduces the overall performance of the Su-25T.

 

Irtysh is also an on-board system, therefore ECM is always available.

[Ironhand]

Irtysh is referred to as the ECM system with capability to automatically dispense chaffs and flares...Irtysh is also an on-board system, therefore ECM is always available.

"...Irtysh ECM system, which includes L166S active IR jammer, UV-26 chaff/Hare dispensers, and Omul active electronic jammer." -- http://www.aeronautics.ru/news/news001/combair009%20-%200008.htm

 

This is the only descriptive reference I have...

I'll go back to my book after work to see the exact wording.

Well, I am back from work and here's what's in the book:

 

Page 115

“The Su-25T is equipped with the Irtysh integrated electronic countermeasure suite which compromises:

1. The L-150 Pastel (Crayon) ….

2. Suhogruz …

3. Chaf dispensers …

4. UV-26 infra red flare dispense unit

5. Gardeniya-1FU active electronic countermeasure set.”

 

Page 112

“…Irtysh electronic countermeasures system.”

 

Page 125

“A new electronic countermeasures system was also developed for the SU-25TM (Su-39), known as MPS-410 Omul (A lake Baikal salmon) …”

During the development, ED said that they didn't have enough information on the Pastel system, and thus were forced to retain the Beroza on the Su-25t.

Unable to type/fly/read ATM I would imagine :D

I understand that. However, I was questioning ECM, not RWR system.
