What is a Hospital Ship?
A hospital ship is designed to be a floating hospital on the ocean or seas, offering medical treatment spanning minor to major surgeries, prescribing medication, etc.
One may wonder when and why they were invented. However, they are not a modern phenomenon; they have existed since ancient times.
The Athenian navy had a ship called Therapia, and even the Roman Navy had a similar ship called Aesculapius. Their names and descriptions indicate they were hospital ships, providing comfort to the wounded and sick.
What is the need for Hospital Ships in the world?
Today, most hospital ships are operated by a country’s navy and used during peacetime and even during war, global emergencies, natural disasters, etc.
In developing nations, there is a shortage of medical providers, medical tools, and medicines needed for surgery and infrastructure. Secondly, some poor communities live in far-flung regions, away from hospitals on land, near the coast. They lack access to basic medical care and suffer.
In all these scenarios, hospital ships come to their rescue. They visit such people and give them timely treatment, almost free of cost.
Use of Hospital Ships during the World War Period
In the 19th century, old and obsolete warships were used as hospital ships to treat the soldiers. Hospital ships were used on a huge scale during the World War, when several passenger liners, such as RMS Aquitania and HMHS Britannic, were converted to floating hospitals.
The hospital ships look different from other ships. They are painted in white and carry a white flag with a red cross. Even their interiors, utensils, and furniture are designed to give the feeling that one is in a hospital on land.
The 2nd Geneva Convention prohibits any military attacks on these vessels; however, during World Wars, even hospital ships were targeted. For instance, Canada’s SS Letitia (i) and HMHS Llandovery Castle were sunk by a German boat, resulting in several deaths despite the status of the ships.
This article explores the 10 largest hospital ships, ranked according to their weight.

USNS Mercy strives to offer medical and surgical operations to support Marine Corps Air and Ground Task Forces, the naval amphibious task forces, Army and Air Force units, and battle forces.
She can also provide surgical services to government agencies during disasters, offer humanitarian relief, and function during peacetime military operations.
