Why the Britannic matters in maritime history

More than 100 years after the sinking of the HMHS Britannic, sister ship to the Titanic, divers have recovered artefacts from the wreck in the Aegean Sea. The discovery is being hailed as a milestone in both historical research and underwater archaeology.

The Britannic was the third and final vessel of the White Star Line’s Olympic-class ships, alongside the Olympic and the ill-fated Titanic. Launched in 1914, the Britannic was originally designed as a luxury ocean liner but was requisitioned as a hospital ship during World War I. On November 16, 1916, it struck a German mine off the Greek island of Kea and sank in less than an hour, killing 30 people. Unlike the Titanic disaster of 1912, the majority of those on board were rescued.

How divers recovered the artefacts

In May 2025, an 11-member team of professional divers carried out a complex recovery mission at a depth of more than 120 meters (390 feet). Using advanced closed-circuit diving equipment, they retrieved artefacts for the first time since the Britannic’s sinking.

The expedition was led by British maritime historian Simon Mills, founder of the Britannic Foundation and legal owner of the wreck. Details of the mission were only released this week by Greece’s Ministry of Culture, which authorised the operation.

Among the items recovered:

• The ship’s lookout bell
• A portside navigation lamp
• A pair of binoculars
• Ceramic tiles
• Personal effects and furnishings from first- and second-class cabins

The artefacts were carefully raised using inflatable lifting bags, stored in protective containers, and transported to conservation labs.

Conservation and exhibition plans

After initial cleaning to remove marine growth, the artefacts were transferred to the Ephorate of Underwater Antiquities laboratories in Athens. Greek officials say the long-term plan is to display them at the forthcoming National Museum of Underwater Antiquities in Piraeus, which will dedicate a section to World War I maritime history.

According to the ministry, conditions during the dive were “particularly challenging,” with strong currents, limited visibility, and fragile structures limiting what could be retrieved. Some targeted artefacts were left behind due to their delicate state.

Why this discovery is significant

This is the first time objects have ever been lifted from the Britannic’s wreck, making it a landmark in shipwreck exploration. While Titanic artefacts have been displayed in museums worldwide, the Britannic remained untouched until now due to its status as a designated war grave.

Historians and archaeologists say the finds could shed new light on:

• Design differences between Britannic and Titanic, including safety modifications made after the Titanic disaster.
• Life aboard a hospital ship, from medical equipment to cabin furnishings.
• WWI naval history, highlighting how civilian ships were adapted for wartime use.

The enduring legacy of Titanic’s sister ships

• Olympic served as a successful passenger liner and troopship, retiring in 1935.
• Titanic met its tragic fate on its maiden voyage in 1912, killing over 1,500 people.
• Britannic, though considered the safest of the three, never carried paying passengers in peacetime before its wartime sinking.

Together, these ships remain symbols of early 20th-century naval ambition, luxury, and tragedy.

TL;DR

For the first time, divers have recovered artefacts from the Britannic, Titanic’s sister ship, which sank in 1916 during World War I. Items including a bell, navigation lamp, and personal belongings will be conserved and displayed in Greece’s upcoming National Museum of Underwater Antiquities.
