Mistral is 16,500 tonnes (empty) and 21,300 tonnes (full load), Juan Carlos is 26,000 tonnes loaded, if that's true, Most or all of the other proposals would be cut out, except for the Americans. RFP generally indicate minimum system requirements, I doubt the IN will aim that high, and blow the competition out!. Also Russia had to update its docks to accommodate the Mistral, as they had never dealt with a ship that big. I have no clue as to how the Indian shipyards would accommodate a 40k toner.
INS Jalashwa is:
Light: 8,900 tonnes
Standard: 12,000 tonnes
Full load: 16,600 tonnes
assuming they are referring to standard load, 12k it will fit the bill, if their minimum requirement is of 10k. Also at 12k , Jalashwa is one of the largest ships of the IN, coming second only to the carriers, so its not a small ship by any means
