#Opinion IAF is not interested & I think they have a valid reason. You don't want a new 4.5 Gen aircraft after 2035 when you will be inducting a 5th gen aircraft while receiving Tejas Mk-2 in parallel, for IAF, Future is stealth combined with manned unmanned system, any further requirements for 4.5 Gen can be addressed through Tejas Mk-2, as the single or double engine is not a decisive factor for IAF's Operations.

Coming to the Navy, they will need some 100-140 TEDBF in Future, 26 Rafale is just a stop-gap since the Navy is not interested in the MiG 29Ks.
The future is TEDBF with Unammend Systems.
