The Iwo Jima carries maybe 30 helicopters, with a small amount of fuel. Not much additional supplies.
The New York can land 2 big / 4 small birds.
A nuclear carrier carries a bunch of birds, can conduct refueling operations for much longer, and can pull 400,000 gallons of fresh water out of the ocean each day. Not to mention cat carry a lot more supplies and other useful stuff.
Thanks for the feedback.
Copter fuel and the ability to make that much fresh water each day are big assets.
My concern is/was the limited access to the islands re shallow water that would prevent a Nuc Carrier to get very close to them or their docks (if the docks/piers are still in operational condition.)
