SS Britannic was an ocean liner of the White Star Line. It was the first of three ships of the White Star Line to sail with Britannic name. Britannic was a single-screw passenger steamship equipped with sails built for the White Star Line's North Atlantic run. It was initially to be called Hellenic, but, just prior to her launch, her name was changed to Britannic. Together with her sister Germanic, Britannic sailed for nearly thirty years, primarily carrying immigrant passengers on the highly trafficked Liverpool to New York City route. In 1876 it received the Blue Riband, both westbound and eastbound, by averaging almost 16 knots (30 km/h).
