It takes a long time to make a new jet.
Tejas Mk2 may be considered as a follow on program, but Tedbf is a ground up new aircraft/program. Expecting it to be in service anytime before 2030 is an impossibility.
I'll give a little formula for understanding the effective limitations that a STOBAR carrier puts on an aircraft.
Fuel carried from StoBar = 50% of CatoBar
Payload carried from StoBar = 50% of CatoBar.
A significant amount of fuel is expended in taking off and reaching a patrolling/cruise...
Whats that going to achieve?
NLCA was a tech demonstrator, not an actual option to buy for the navy. It doesn't have anywhere near the T/W, load margins to fly from a Stobar carrier.
Dokdo is korean. A formal declaration to buy 24 of F35B has already been put out.
Japanese too are reconfiguring their Izumo class for F35B, of which 42 have been ordered.
Both these ships displace 30k tons, and will be ordered /configured in pairs.
'Ignorance' covers that.
Ignorance about future integration of different platforms being one of them.
Managing to fit lifts 10 feet wider than what they are now, shouldn't have been that big a deal.
Lift size is no more than 30 ft wide ( same as Kiev class)
Mig 29k folded wingspan - 26 ft
F-18E/F folded wingspan - 32 ft
Rafale fixed wingspan - 36 ft (no wing folding)
