umpteen reviews must have missed it.
You cannot design for something that you dont know , The DND did not knew beyond 29K and Tejas and IAC was designed around these two types. Not just the lift but also the run way needed for take off land , berthing space above and below deck etc.
Even today we dont have any specs of any new types beyond what the OEM would say and that needs to be actually proven either on land based mockups of AC like we did for Tejas or on real one.
You need to account for other assets like ASW/ASuW choppers , Rescue Helicopters , Heli based AEW like Ka-31 that would make more than 60 % of IN Carrier asset
You dont design a ship by waking up one fine day and working on some CAD adding 2 exta meters for Lift and 50 extra meters of length and width add another 5 m so that a F-18 or Rafale can take off , These things are designed from scratch and other components needed are also taken into account , ship modelling is done and extensively tested and it can take many months and years to finalise one design , plus there are hazaar other cheez taken into account.
The IAC core design would have been frozen like 5-6 years back with all the vendors identified and agreement signed with them for the equipment ,powerplant etc , Then the design is passed to SY who while building do the other minor changes in design as required.
Its a complex and mamoth task and they cannot just change the design just because some new aircraft is on the horizon.
The only option is to make Naval Tejas and 29K fly of IAC and Vikramaditya and make it work both are quite potent and any future aircraft on new AC will only come 12-15 years later.
