I've been in the medical area of an LHA; it's big, right below the flight deck, and designed for both daily sick call and combat medicine. Three of those will be nowhere close to the capacity of a major city hospital, but it does give you three ER's, three great flight decks which can greatly facilitate moving patients to other facilities, and three bases for logistics while Mayor Bloomberg's staff figures out what to do next. Did I mention that they have outstanding communications capability?

I see these three big decks being used as logistics bases to get NYC's critical infrastructure back in order. Reliable communications, electricity, fuel, and air, sea and land logistics. Besides the flight deck, they have a floodable well deck for boats to move items like trucks.

It will be interesting to see how they are used.
