Moore Dry Dock Company was a ship repair and shipbuilding company in Oakland, California. In 1905, Robert S. Moore, his brother Joseph A. Moore, and John Thomas Scott purchased the National Iron Works located in the Hunter's Point section of San Francisco, and founded a new company, the Moore & Scott Iron Works Moore had previously been vice president of the Risdon Iron Works of San Francisco. Scott was nephew to Henry T. and Irving M. Scott, owners of the nearby Union Iron Works, where John had risen from apprentice to superintendent. Their new business was soon destroyed by fire resulting from the San Francisco earthquake.

The Type R ship is a United States Maritime Administration (MARAD) designation for World War II refrigerated cargo ship, also called a reefer ship. The R type ship was used in World War II, Korean War, Vietnam War and the Cold War. Type R ships were used to transport perishable commodities which require temperature-controlled transportation, such as fruit, meat, fish, vegetables, dairy products and other foods. The US Maritime Commission ordered 41 new refrigerated ships for the US Navy. Because of the difficulty of building refrigerated ships only two were delivered in 1944, and just 26 were delivered in 1945 and the remainder in 1946–48. The 41 R type ships were built in four groups. Two of design types were modified type C1 ships and two were modified type C2 ships. The United Fruit Company operated many of the R type ships in World War II. The type R2-S-BV1 became the US Navy Alstede-class stores ship and the type R1-M-AV3 became the US Navy Adria-class stores ship.
