Located in the second inner harbor of Scheveningen, Hr. Ms. Mercuur is a wooden ocean minesweeper. She was built for the United States Navy and transferred to The Netherlands in 1954. Originally named Onverschrokken she was provided as part of the Marshall Plan (Mutual Defense Assistance Program). Mercuur and five sister ships assisted in the vital job of clearing sea mines from Dutch harbors after the war. She often participated in multinational (NATO and bi- or tri-national) exercises off the European coast during the Cold War.
In 1972 the Netherlands Navy was in need of replacing the then aging torpedo assist ship Mercuur, serving in support of torpedo tests and trials by submarines, and later also helicopters and maritime patrol aircraft. In order to enable for a fast replacement, the Onverschrokken was modified to take over this torpedo assistance job and renamed Mercuur.
In 1987 she was decommissioned, mothballed and added to the Reserve Fleet. Today she is a museum where visitors visitors experience the life on board a U.S. Navy and Royal Dutch Navy ship of the 1940s and 1950s.
