The USNS Mercy is on the River today. She’s coming to the shipyard at Swan Island in Portland. She’s one of two Military Sealift Command hospital ships that have been enlisted to provide medical support during the pandemic. The USNS Mercy is on the West Coast, and the USNS Comfort is on the East Coast. These ships are easy to spot: bright white with red crosses on their sides.
