Class and type: British Yard Minesweeper
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. It was severely damaged in 1996, and was planned to undergo a complete refurbishment in 2009-2011. The ship is named after the Greek mythological figure Calypso.
Calypso was originally a minesweeper built by the Ballard Marine Railway Company of Seattle, Washington, United States for the United States Navy for loan to the British Royal Navy under lend-lease. A wooden-hulled vessel, she is built of Oregon pine.
Calypso carried advanced equipment, including one- and two-man mini submarines developed by Cousteau, diving saucers, and underwater scooters. The ship was also fitted with a see-through “nose” and an observation chamber 3 meters (9.8 ft.) below the waterline, and was modified to house scientific equipment and a helicopter pad. The Calypso underwater camera is named after this ship.
