Not really anything educational per say but an HD video tour through one of the U.S. Navy's hospital ships. There are two of them, this is the USNS
Mercy. They are very much floating hospitals, 1,000 beds is the maximum capacity although apparently it's typical they outfit for 250 to 500 at most.
She was launched in in 1975 as a super tanker SS
Worth and refitted and recommissioned in 1986 as the
Mercy. Perhaps
@Stuckinthe80s can provide insight or details, at least in general terms since this is pretty different from his assignment in the Navy.
