HMHS Britannic was the last and largest of three ocean liners built by the White Star Line shipping company. Following the sinking of her sister ship, RMS Titanic in April 1912, the hull of the 53,000-ton Britannic was redesigned and it was launched on February 26, 1914.
It was sunk on November 21, 1916, after being struck by a single mine blast. The wreck was first discovered by Jacques Cousteau in 1975.
