HMHS Britannic was the third and final of the Olympic-Class Ocean Liners and the sister ship of the RMS Titanic and RMS Olympic. Some claim her original name was going to be RMS Gigantic and it was changed after the sinking of the Titanic (as 'Giant' in her name would scare away the traumatised public) whilst still in construction to RMS Britannic but White Star Line denied this. The Britannic never sailed as a Royal Mail Ship. Before her maiden voyage could begin, WWI started. Her designation was changed to HMHS, and its occupation was changed to a hospital ship. HMHS means His Majesty’s Hospital Ship. It did not survive the war and therefore never sailed as an ocean liner. In that role she was shaken by an explosion in the Kea Channel off the Greek island of Kea on the morning of November 21st, 1916; and sank with the loss of 30 lives. However, most of the lives lost are thought not to have been as a result of drowning but more of a result of the propellers smashing up the lifeboats sucked towards them. The Britannic most likely hit an underwater mine, but a torpedo attack is highly unlikely, as neither side in the war was allowed to attack any hospital ship of any nationality.
