Tarang has been replaced with, first 4-channel R118, then 6-channel R118 and now with fully-digital RWR DR-118 Dhruti. Contract was signed for 129 RWRs way back in March 2023:Not wholly Indian yet. We're still using the SAP518+ Tarang combo on the MKI. Qualifying an upscaled indigenous jamming pod derived from the MK1A program is likely going to take time. Been reading about the MKI getting towed Rafael X-Guard decoys but could just be a rumour.
EW is one area the MKI is very vulnerable imho. No MAWS or expendable decoys like the ALE-50, for example.
Remember reading about a podded/pylon mounted MAWS (Elisra?) being trialled on the MKI. Current status unknown.
If we plan to use the type through 2055, the EW suite needs special attention. It'd be great to port the DIRCM from the Su-57 over to the MKI. Could cause structural issues though.
Post Ukraine war, SAP-518 is compromised now and IAF just say MKIed it. Don't worry, even current MKI's EW capabilities are formidable. Dual HBJ GaN pods are for UPG. version and are designed to work with even more advance Digital RWR-NG that can intercept frequencies from 1 to 40GHz just like Rafale's SPECTRA.
