SCAF/French 6gen will have a whole lot of power replacing whatever the Indians are using for their carrier aircraft. Rafales and Mig29Ks? So it'd be a challenge to the TEDBF program.
SCAF/Fr6G would also have good capabilities for replacing Flankers.
I'm above 90% certain that TEDBF will never be funded, at least in its current form. Especially if Navy goes through with the additional 31 Rafale-Ms as is rumoured.
Vikramaditya (ex-Adm Gorshkov/Baku) will more than likely see early retirement (I'd say between 2035-2040 tops). MiGs will see it through to the end. They won't have it turn into another Kuznetsov when there's a local yard (CSL) that's itching to build more carriers.
With 26+31 Rafale Ms, the Vikrant will have more than enough airframes for a high ops tempo. Rafale's still got an upgrade path ahead of it (F5, F6 and so on), so if they go through with an order for a 2nd ship of the Vikrant-class (its among the proposals to keep the CSL yard happy, last I heard), additional Rafales are probably the better, safer & cheaper option than pursuing TEDBF in its current form, which is meant to be a STOBAR-optimized design, and all for a production run of less than 100 airframes.
Rafale will likely have enough airframe life to serve till the STOBAR ships retire, especially if backed up by stealthy CCAs in the next decade. IMO, it's only the future CATOBAR carriers that are worth pursuing a new naval fighter for.
And I think the navy is also evolving its deck-based fighter requirement toward that end (see attached)...it might ultimately come down to either a navalized AMCA or the French 6G that's supposed to go on PANG/France Libre.
But the navy/govt still haven't made a definitive call on the future carrier plans (like size, number, N-propulsion or not), so I doubt they'll be in a hurry for that role. IAF would be the service that's much more interested in the near future.
