Well, these ships are great but the USNS Comfort (1000 beds) won’t get to New York City for at least a couple of weeks and it’s optimized for Trauma, not Infectious Diseases so like the USNS Mercy (deployed to Los Angeles last I checked) it’s going to be a parking space for everything except Coronavirus.
I’m not sure why Andrew Cuomo is so excited about it other than he’s trying to suck up so he gets the other stuff he needs.
