There are some proves for Kh 59 in IAFs inventory for the MKI, but I can't say which versions. Brahmos is mainly an anti ship missile, that was converted for land attack too. In both roles it offers much advantages with the points you already mentioned and the lighter version that will be developed for Rafale, Mig 29K and most importantly for FGFA, can be used by MKI in higher numbers too. Till then Kh 59 will be a good addition for heavy attacks, but I still hope for Scalp at upgraded Mirage and Rafales. Long range deep strike capability is important for IAF and we need a good alternative to the MKI in this role too.
