"Aluminaut" is best known for helping recover a lost unarmed U.S. hydrogen bomb in 1966 and recovering its smaller fellow deep-submergence vehicle, DSV "Alvin" in 1969, after "Alvin" had been lost and sank in the Atlantic Ocean the previous year. After retirement, "Aluminaut" was donated to the Science Museum of Virginia in Richmond, where it is on permanent display.
