Minesweeper

USS Lucid MSO-458

📍Stockton, CA

The USS Lucid (MSO-458) is an Aggressive-class ocean minesweeper built for the United States Navy during the Cold War era. Commissioned in May 1955, the 172-foot vessel was specifically constructed with a non-magnetic wooden hull—composed of laminated Douglas fir and white oak—and outfitted with non-magnetic stainless steel and bronze fittings to safely navigate waters filled with magnetically triggered naval mines. During her active military career, the Lucid primarily operated in the Pacific Theater, executing four deployments to the Western Pacific. Her most notable service occurred during the Vietnam War, where she participated in Operation Market Time, conducting grueling coastal patrols to interdict communist weapons smuggling and providing critical mine-clearance support for American fleet operations.

After being decommissioned in 1970, the Lucid entered a long period of neglect, serving as a houseboat in the Sacramento River Delta for decades before being largely stripped by vandals. However, her story took a dramatic turn in 2011 when she was acquired by the Stockton Historical Maritime Museum in California. As the last surviving ship of her specific class, a dedicated volunteer effort has been working to restore her to her 1960s configuration. Moored on the San Joaquin River in Stockton, the ship now serves as a floating museum and an educational memorial dedicated to the often-overlooked history of the Navy's wooden-hulled minesweepers and the "wooden ships and iron men" who sailed them.
