RMS Britannic

RMS Britannic was the third and largest of the White Star Line's Olympic-class ocean liners, built as a running mate to Olympic and Titanic but redesigned with a strengthened hull and additional lifeboats after the Titanic disaster. She never entered the civilian passenger service for which she was built, having been requisitioned as a hospital ship for the First World War, and in 1916 she sank in the Aegean Sea after striking a naval mine, becoming the largest ship lost in that war and, like Titanic, one of the most studied shipwrecks of the twentieth century.
