She served in the Pacific Ocean theatre of operations through the end of the war, earning one battle star, and then returned to the United States for disposal.

The urgent need for ammunition carriers to resupply the fleet prosecuting the final stages of the war against Japan in the Pacific Ocean prompted the Navy's acquisition of Bucyrus Victory and several of her sisters.

Soon after the successful conclusion of that experiment, the cargo carrier headed back to the U.S. West Coast, arriving in San Francisco, California, on 20 January.

The ship remained at Ulithi for just over two weeks, first discharging her original cargo to fleet units preparing for the assault on Okinawa and then reloading for her resupply role in the impending campaign.

Though enemy air attacks interrupted her work and sometimes stopped it altogether, Bucyrus Victory suffered no damage and took little or no part in the anti-air defense of the anchorage.

Bucyrus Victory's second tour of duty at Kerama Retto lasted a fortnight; and, once again, Japanese aviators contributed all they could in the way of complications to her efforts.

From mid-June to late September, Bucyrus Victory lay at anchor in San Pedro Bay off Leyte receiving and storing ammunition.
