A good insight on China, Pakistan's EW capabilities although many are not well known but in the light of this news, we can understand the EW capability of JFT to some extent....
"While undoubtedly a major player in the region, EW provision within China’s People’s
Liberation Army Air Force (PLAAF) remains as enigmatic as many other aspects of the
People’s Republic’s military. While it is clear that PLAAF FC-1, J-7, J-8, J-10 and J-11 aircraft are all equipped with at least an RWR and a CMDS, trying to pin down the precise nature of such equipment is much harder. This said, AMR believes that most PLAAF EW equipment is produced nationally, with confirmed over time examples including the China
National Electronics Import and Export Corporation’s (CEIEC) GT-1 CMDS; the
Northeast Research Institute of Technology’s (NEIET) SE-2 ultra-violet passive MAW and TM series laser warners and the Southwest China Research Institute of Electronic
Equipment’s (SCRIEE) 2 to 18 GHz band KJ8602/KJ8602A RWRs, 2 to 40 GHz
KJ8602B/KJ8602BC RWRs and 6.5 to 40 GHz band KG300G pod-mounted radar jammer. Of these, the SE-2 has been associated with the FC-1 (designated as the JF-17 in Pakistani service), while usually reliable sources have made mention of a fast-jet radar jammer designated as the RKL-800 and an additional pair of CMDSs designated as the GT-4 and the RKZ-404E. Elsewhere, it is almost certain that
China has exported elements of its indigenous fast-jet EW technology, with nationally produced RWRs and CMDSs being likely to have been sold to Bangladesh (24 F-7BG fighters), Myanmar (60 F-7Ms), Pakistan (120 F-7P/- 7MP) and Sri Lanka (four F-7BS). In addition and as already noted, Pakistan is co-producing the FC-1 as the JF-17 and it is probable that the initial JF-17 production run is being equipped with a percentage of Chinese avionic equipment that may include EW provision.
