You are right probably notGiulio wrote:elint is a kind of intelligence recon, you listen and record the foreign electromagnetic emissions. It is not ecm or eccm. Actually generally I think elint comes before of the ecm: first you listen and register, then someone will study a way to disturb them (ecm).
The Mig-25 BM I think it has not the radar and missiles for the awacs killing: the Mig-25BM has avionics for detect enemy radar stations and guide on it the Kh-58 missiles. The Kh-58 missiles or kh-31 afaik are air to ground missiles, not air-to-air. I never heard of Mig-25 awacs-killer.
For awacs killing I think needs a long range radar and a long range missile (like the novator?) and also in this way it seems to me very difficult, but I don't know. Maybe that it is better try to jam the awacs, but I don't know.
