The only two usp TEDBF has is its folded wingspan and its promise to deliver early than amca. But if its timeline slips, both its usp neutralizes as vikky completes its lifetime.i personally think indian navy should invest heavily in tedbf because its something between mwf and amca if that comes till 2026 even iaf might buy some sqdns with some modifications, one more thing i got to know from the guy who took ddr interview(aero 2021) was tedbf with have semi reccessed bays
TEDBF is basically a clean sheet aircraft who's design is heavily influenced by our past experience with lca.
If you let go of vikky than both iac1 and future iac ii can accommodate amca or f-35
