The podded wingtip mounted KNIRTI SPS-171 / L005S Sorbtsiya-S H/I band defensive jammer has been reported, this system being an evolution of a jammer developed for the Backfire C. The Sorbtsiya-S, unlike most Western jamming pods, is designed to operate in pairs and uses forward and aft looking steerable wideband phased arrays to maximise jamming effect. It is worth observing that the Sorbtsiya is clearly built to provide cross-eye jamming modes against monopulse threats, and the wideband mainlobe steering capability provided by the phased array permits best possible utilisation of available jamming power. A graded dielectric lens is employed.

The cutaway image is quite interesting, I’d love to know how it works.
