So they really want to develop and field a fighter akin to the Rafale for the 2038+ scenarios? Why not better developing a navalised variant of the AMCA?
Probably because carrier operations were (probably quite sensibly) never envisaged for MCA/AMCA, such that the aircraft would require extensive redesign to be even notionally adaptable to carrier operations. MCA/AMCA is more than fifteen years old at this point, and existing stakeholders who wish to see it in service before the centenary of the Republic would be advised to resist any such rescoping of the project. The journey is arduous enough without further moving of the goalposts. The more recent TEDBF program appears to owe its existence to the failure of LCA-N owing to marginal performance characteristics (which supports LCA detractors' contention that even the land-based aircraft is chronically overweight) coupled with growth of ambition over time to an aircraft that could, at least in theory, serve as
the carrier-based manned combat aircraft for IN. Undoubtedly IN will have been reassured by ADA that TEDBF project cost will be minimised via commonality with LCA systems and learnings from that project. Still, it appears to be an insouciant enterprise with long odds of success.
