The HMHS Britannic was launched on February 26, 1914, at a shipyard in Belfast, about two years after her sister ship, the Titanic, sank on April 15, 1912.
The Britannic incorporated a number of improved safety features including a double hull and superior watertight bulkheads. The Britannic sank on November 21, 1916 after striking a German mine in the Aegean Sea. Most of the 1,136 people on board were saved with thirty facilities.
