Prométhée, Submarine wreck off Cherbourg, France
The Prométhée submarine measured 92 meters in length and operated with two 6000 horsepower Sulzer diesel engines reaching 17 knots at surface speed.
During its fifth test run on July 7, 1932, the Prométhée sank near Cape Lévi due to a malfunction in the ballast purge system.
A memorial cross stands in Fermanville since 1933, serving as an annual gathering point to honor the 62 sailors who perished in the accident.
The wreck of the Prométhée lies 80 meters deep at coordinates 49.48.316N, 01.26.421W in the English Channel.
The submarine carried 68 people during its final journey, including engineers and technicians conducting tests on the electrical motors.
