Yeah i was assuming the kitty hawk class was nuc-powered but no it was enterprise which was the first one - oopsAlso, the design is a conventional, as opposed to nuclear-powered carrier. As such, it would give India no additional expertise or knowledge in terms of designing a nuclear-powered vessel of their own.
I still think we need one more carrier to be operational by 2020 (4 total in nos)
And we are already building an IAC and post which planning to build one more IAC in the Cochin Shipyard and the Mazgon Docks is already busy with the Project 15B destroyers the Project 17A frigates and the Project28A corvettes as well as the scorpene subs, besides which both the Garden Reach as well as the Goa Shipyards are ill equipped to build a big carrier and the ATVs are being built in Vishakapattanam
So simply out India is already running on capacity with its domestic shipbuilding capabilitites so if we want a 4th carrier we have to look outwards for the same, Russia is busy planning its own needs all efforts would be in tht direction, so new carriers also look hard to get from external sources - so only logical choice would be to buy a used carrier and currently the only carriers looked like kitty hawk and kennedy - hence my suggestions albeit with certain wrong expectations
