RMS Olympic completed the longest service among the three Olympic-class ships.
Olympic entered service in 1911 and remained active until 1935, giving her a working career of roughly 24 years. She was built by Harland and Wolff in Belfast for the White Star Line and was the first of the Olympic-class trio.
Unlike Titanic, Olympic completed a long commercial career, although she also served as a troopship during the First World War. During that wartime period, she transported troops and survived a torpedo attack. Britannic became a hospital ship and sank in 1916 after striking a mine.
Olympic is sometimes called “Old Reliable” because of her long career and wartime service. Her retirement came after the merger of the White Star Line with Cunard, when older ships were removed from service. Olympic was later dismantled in Jarrow, England.
