The Olympic-class ships were propelled by a combined system of two triple-expansion steam engines which powered the three-bladed outboard wing propellers whilst a low-pressure steam turbine used steam exhausted from the two reciprocating engines to power the central four-bladed propeller giving a maximum speed of 23 knots. With a gross tonnage of 48,158, she surpassed her older sisters in terms of internal volume, but that did not make her the largest passenger ship in service at that time the German SS Vaterland held this title with a significantly higher tonnage. The original dimensions of Britannic were similar to those of her older sisters, but her dimensions were altered whilst still on the building stocks after the loss of Titanic. The vessel is the largest intact passenger ship on the seabed. The wreck was located and explored by Jacques-Yves Cousteau in 1975. Īfter the First World War the White Star Line was compensated for the loss of Britannic by the award of SS Bismarck as part of postwar reparations she entered service as RMS Majestic. Britannic was the largest ship lost in the First World War.

There were 1,066 people on board the 1,036 survivors were rescued from the water and lifeboats. On the morning of 21 November 1916 she was shaken by an explosion caused by a naval mine of the Imperial German Navy near the Greek island of Kea and sank 55 minutes later, killing 30 people. In 19 she served between the United Kingdom and the Dardanelles. She was laid up at her builders, Harland and Wolff, in Belfast for many months before being requisitioned as a hospital ship. She was designed to be the safest of the three ships with design changes made during construction due to lessons learned from the sinking of the Titanic. She was operated as a hospital ship from 1915 until her sinking near the Greek island of Kea, in the Aegean Sea, in 1916.īritannic was launched just before the start of the First World War.

She was the youngest sister of the RMS Olympic and the RMS Titanic and was intended to enter service as a transatlantic passenger liner. HMHS Britannic ( / b r ɪ ˈ t æ n ɪ k/) was the third vessel of the White Star Line's Olympic class of steamships and the second White Star ship to bear the name Britannic.
