HMS Triad, British submarine wreck near Calabria, Italy.

The T-class submarine measured 275 feet in length with six internal forward-facing torpedo tubes and four external tubes for military operations.

Commissioned in September 1939, HMS Triad engaged in North Sea and Mediterranean operations before sinking during combat with Italian submarine Enrico Toti.

The submarine represents the British naval engineering capabilities of the 1930s through its advanced diesel engines and electric motor propulsion system.

The wreck location at coordinates 38.266667, 17.616667 marks the final resting place of the submarine following its last Mediterranean patrol.

This vessel holds the distinction of being the only British submarine sunk by an Italian submarine during World War II naval operations.
