Calypso

The Calypso was a former minesweeper employed by the French Navy. Cousteau leased it, equipped it with a collection of research equipment, and began to sail a number of expeditions and perform vast amounts of research on the sea. It contained, among other things, a heliport, a couple of submarines, and an observation section below the water.

The Calypso was rammed, sunk, and raised about a year before Cousteau died. It was later brought to a museum under the intention of creating an exhibit, and after being passed around a number of French ports, it is currently being restored in order to become a permanent maritime exhibit for tourists.

The Alcyone is now the boat that the Cousteau Society uses in their expeditions.
