Wiki say Sukhoi Su-30MKI has electronic counter-measure systems. The RWR system is of Indian design, developed by India's DRDO, called Tarang, (Wave in Sanskrit). It has direction finding capability and is known to have a programmable threat library. The RWR is derived from work done on an earlier system for India's MiG-23BNs known as the Tranquil, which is now superseded by the more advanced Tarang series. Elta EL/M-8222 a self-protection jammer developed by Israel Aircraft Industries is the MKI's standard EW pod, which the Israeli Air Force uses on its F-15s. The ELTA El/M-8222 Self Protection Pod is a power-managed jammer, air-cooled system with an ESM receiver integrated into the pod. The pod contains an antenna on the forward and aft ends, which receive the hostile RF signal and after processing deliver the appropriate response.
Can you re- read what I wrote??? I never say MKI has no EW suit. All the EW suit you mention on MKI is absent from J-11b becos its definitely a different ball game. It's will be complete Chinese version. Doesn't mean the Suit on MKI is inferior.. I think is in fact very capable.
