Which countries have hospital ships?

At present, only a few countries in the world, such as the United States, the Russian Federation and China, have hospital ships with offshore medical rescue capabilities. The U.S navy has two hospital ships, namely, T-AH- 19 MERCY and T-AH-20 COM-FORT. These two hospital ships were refitted by the super cruise ship "Saint Claremont". These two hospital ships are the largest hospital ships in the world at present, with complete facilities, beds 1000, and the ability to treat 300 people day and night. At present, the Russian Navy has three 320 "ob river" class hospital ships built in the 1970s. This class of ship has 80 crew members and 200 medical staff, with 400-500 beds. China's "Square Boat" hospital ship is the world's first specially designed 10,000-ton hospital ship with the ship number 866. The "Square Boat" has high technical content and comprehensive functions, and its hardware facilities are equivalent to the level of a third-class first-class hospital.
