USS Lucid (AM-458/MSO-458) was an Aggressive-class minesweeper acquired by the U.S. Navy for the task of removing mines that had been placed in the water to prevent the safe passage of ships. She was launched soon after the Korean War, sailed on four WestPac cruises and served two tours in Vietnam. Lucid was decommissioned at the end of 1970 and placed in mothballs after only 15 years of service, as the Vietnam War was winding down and there was no longer a need for a large fleet of minesweepers. She was purchased by some civilians and served as a houseboat for ten years before being sold again and used as a warehouse in the Sacramento Delta. In 2005, Lucid was acquired by a foundation seeking to save a ship of this class and is now undergoing restoration as a museum ship by a maritime museum in Stockton, California.
