Yes exactly, India will need LHD and amphibious assault ships to complement CV for future power projection and it will help in designing a doctrine for such kind of future ships, instead of more then two aircraft carriers I would have suggest such class of ships for the navy to mobilise a few battalion strength commando troops towards war zone, Aircraft carriers without sufficient escort ship can be vulnerable in a face off situation, with the current strength of 8 destroyers and 12 frigates, I don't think it would be a good idea to increase aircraft carriers in the fleet, either ships would be engaged defending the CV or the CV will be vulnerable otherwise.
On the other note the US is believed to keep strings attached with her military tradings.
