The HMHS Britannic Expedition is a project dedicated to the exploration, documentation, and responsible storytelling of the largest intact passenger shipwreck in the world. Resting at 120 metres in the Aegean Sea, Britannic represents one of the most demanding and historically significant objectives in technical diving. For our team, the start of this expedition marked the realization of a long-held dream and the beginning of a structured, multi-phase effort to explore one of the most important underwater heritage sites on the planet.

Built as the third Olympic-class liner for the White Star Line, Britannic was the sister ship of Titanic and Olympic. Launched in 1914, she never carried commercial passengers. Instead, she was requisitioned during the First World War and converted into His Majesty’s Hospital Ship (HMHS), serving as a floating medical facility in the Mediterranean. On 21 November 1916, while transiting the Kea Channel, Britannic struck a German naval mine and sank in just 55 minutes. Thanks to improved evacuation procedures, over 1,000 lives were saved, though 30 people lost their lives. The wreck was discovered in 1975 by Jacques-Yves Cousteau and remains remarkably intact.

Diving Britannic demands absolute precision, discipline, and respect. Her immense scale, extreme depth, limited bottom time, and long decompression place her firmly in the realm of advanced trimix and CCR diving. Often described as the “Everest of technical diving,” she allows no margin for error. Through carefully planned dives, our team’s goal is to capture high-quality imagery and footage, document key external features of the wreck, and contribute to a deeper understanding of Britannic, while fully respecting the historical, legal, and ethical framework that protects her. 

The project focuses on:

• Capturing high‑quality imagery and footage.
• Documenting key external features of the wreck.
• Respecting both the history and the legal protection of the site.
