HMHS Britannic was the third ship as well as the largest of the Olympic class ocean going liners to be built by the White Star Line. She was the sister ship to the ill fated RMS Titanic and The RMS Olympic. She was intended to go into service operating between Southampton and New York, the First World War broke out shortly after her launching but before she could make the first trans-Atlantic crossing. Due to the war the ship returned to the Belfast yard where she was built to be laid up possibly for the duration of the war.

The ocean liner Britannic was the later built sister ship to the Olympic and the Titanic. Being unfinished at the start of the Great War, the ship entered service as a hospital ship and sunk in 1916 in the Mediterranean Sea. An Organ was obviously not needed on a hospital ship and it disappeared from history to surface in 2006 in Switzerland.
