RV Calypso is a former British Royal Navy minesweeper converted into a research vessel for the oceanographic researcher Jacques Cousteau, equipped with a mobile laboratory for underwater field research. She was severely damaged in 1996 and was planned to undergo a complete refurbishment in 2009–2011 that has not been accomplished. The ship is named after the Greek mythological figure Calypso.
