RV Calypso is a former British Royal Navy Minesweeper converted into a research vessel for the oceanographic researcher Jacques-Yves Cousteau, equipped with a mobile laboratory for underwater field research. She was severely damaged in 1996, and is undergoing a complete refurbishment in 2009. The ship is named after the Greek mythological figure Calypso.

World War II British Minesweeper (1941–1947)

Calypso was originally a wooden-hulled minesweeper built for the British Royal Navy by the Ballard Marine Railway Company of Seattle, Washington, USA. She was made from Oregon pine.

She was a BYMS (British Yard Minesweeper) Mark 1 Class Motor Minesweeper, laid down on 12 August, 1941 with the yard designation BYMS-26 and launched on 21 March, 1942. She was commissioned into the Royal Navy in February 1943 as HMS J-826 and assigned to active service in the Mediterranean Sea, reclassified as BYMS-2026 in 1944, laid up at Malta and finally struck from the Naval Register in 1947.

Maltese Ferry (1947–1950)

After World War II she became a ferry between Malta and the island of Gozo, and was renamed after the nymph Calypso, whose island of Ogygia was mythically associated with Gozo.

Jacques-Yves Cousteau's Calypso (1950–1997)

The Irish millionaire and former MP, Thomas Loel Guinness bought Calypso in 1950 and leased her to Cousteau for a symbolic one franc a year. Cousteau restructured and transformed her into an expedition vessel and support base for diving, filming and oceanographic research.
