Why The Britannic?

The Britannic was a transatlantic passenger liner that was a part of the White Star Line’s Olympic class steamships. The first was the RMS Olympic, the second was the RMS Titanic and the Britannic was the third and final vessel that White Star Line ordered. The ship was 882 feet (268.834 meters) in length and 175 feet (53.34 meters) high, weighing just under 50,000 tons; with these dimensions, the Britannic is the largest ocean liner that has ever sunk.

The Britannic’s existence was conceived through a dream of having a fleet of the largest, safest and most luxurious passenger liners by J. Bruce Ismay and Lord Pierre. This dream was actualized by naval architects Thomas Andrews and Alexander Carlisle.

Only a year after the conception, they started construction on the first two ships, the Olympic and the Titanic; due to their extreme size, only two ships could be built at once. The construction of the Britannic started in 1911 but was completed in 1914, a whole two years after the unfortunate sinking of her sister ship, the RMS Titanic on her maiden voyage.

In August 1914, the Britannic was all set for her maiden voyage between New York and South Hampton; unfortunately, World War I began before she could depart. Though originally bigger ships were not being requisitioned for the war, the number of casualties determined large hospital ships were a necessity. In November of 1915, the Britannic was taken out of storage at Belfast, painted white with a large red cross, and renamed HMHS (Her Majesty’s Hospital Ship) Britannic to be used in the first world war. The ship’s dining areas and rooms were converted into patient care rooms and operation rooms.

When, Where and Why She Sank

After completing five successful missions as a hospital ship, the Britannic took her last voyage. The ship left Naples on a Sunday afternoon in November 1916 after a break in a storm and made her way toward the Kea Channel.

Enroute to Lemnos from South Hampton,  the ship was crossing the Kea Channel. Unbeknownst to those onboard, the channel had been planted with mines less than a month before the Britannic’s voyage through it. On the 21st of November 1916, a mine hit the hospital ship on the starboard side and caused a lot of damage. Her Majesty’s Hospital Ship Britannic started filling with water, and the transmissions were damaged; SOS messages were being sent out, but nothing was being received.

Evacuation plans were in full swing within a few minutes of the explosion; the blast was so bad that the Britannic was in the same condition in ten minutes that the Titanic was in one hour. The captain made all efforts to beach the ship at Kea Island, but the damage to the ship was not allowing it. The ship became a casualty of the first World War and sank rapidly onto the seafloor from the starboard side. 1035 people survived the explosion, and 30 lost their lives.

HMHS Britannic - 122m Below The Surface

The wreck of the HMHS Britannic lies 400 feet (122 meters) below the surface and is the largest ever ocean liner to sink. The wreck lies about 3 nautical miles off the shore of Kea, Greece, in the Aegean Sea.

The Britannic is an idyllic dive for experienced technical divers considering it is so close to the shore and at a relatively achievable depth.
