The Britannic, which was originally to be called Gigantic, was renamed before her launch on 26 February, 1914. She was slightly larger than the other two ships (Titanic and Olympic) due to additional safety features which were incorporated after Titanic sank.
Before she could even enter service, she was requisitioned as a hospital ship and sent to Turkey to serve in World War One. On her fifth voyage, she struck a mine off the coast of Greece and sank in under an hour.
Violet Jessop, a White Star Line stewardess, survived the sinking of the Titanic and Britannic and was also aboard the Olympic when she collided with the Hawke.
