The bathyscaphe Archimède is a deep diving research submersible of the French Navy.

[2] In 1964, Archimède descended into "what was then thought to be the deepest part of the Puerto Rico Trench",[3] which the NY Times reported as 27,500 feet (8,400 m).

[7] On 27 November 1961, Archimède achieved a speed of 3 knots (5.6 km/h; 3.5 mph), over a distance of 4.5 miles (7.2 km) at a depth of 7,870 feet (2,400 m) in the Mediterranean Sea.

[11] Archimède explored the Mid-Atlantic Ridge jointly with the submarine Cyana and submersible DSV Alvin, in Project FAMOUS (French-American Mid-Ocean Undersea Study) in 1974.

[17] Since 2001, Archimède is on display[18] at the Cité de la Mer museum in Cherbourg.
