[1] She sailed unescorted from the San Francisco Bay area in spring 1945 with a cargo of naval munitions bound for Ulithi Atoll in the Western Caroline Islands, operated by the Pacific-Atlantic Steamship Company.

Like other "ammo" ships, the Davidson Victory was stationed at a safe distance from the anchored fleet due to her volatile cargo.

Due largely to its late entry into the war, the Davidson "never heard a shot fired in anger."

The Davidson Victory continued to transport foodstuffs and other cargo to Japan under the direction of the US War Shipping Administration until 1948, when it was leased to the Pacific-Atlantic Steamship Company of Tacoma, Washington and renamed the SS Montana.

Ownership of the Montana was transferred to the States Steamship Company in 1955, and the ship was acquired by US Department of Commerce in 1961.
