From there, she refueled ships conducting exercises off the California, Mexican, and Panamanian coasts and carried fuel to shore bases in the Canal Zone.

In June, she returned to the east coast; underwent overhaul; and, in August, resumed gulf coast-east coast-Caribbean shuttle runs.

In January 1925, she returned to the Pacific for winter maneuvers; then, in April, departed San Francisco for Hawaii to support units participating in joint Army-Navy exercises.

After a stop at Wellington, N.Z., she once more delivered petroleum products to Samoa; and, on 1 September, she departed Tutuila to return to the United States.

In 1929, she interrupted this schedule to carry fuel and torpedoes to the Philippines before returning to the United States to resume her previous operations.

In mid-August, she arrived at San Pedro and, for the next seven months, operated along the California coast with periodic fuel, freight, and passenger runs to Pearl Harbor.

Then, in late March, she departed Boston to deliver fuel oil, aviation gas, and ammunition to Loch Ewe, Scotland.

Two days later, the rendezvous was completed, and the convoy of 43 merchant ships moved west on a course to maximize air coverage from bases on Iceland, Greenland, and Newfoundland.

Further west, 47 German submarines, organized into Groups "Star," "Specht," and "Amsel," were positioning themselves along projected convoy courses between Iceland and Newfoundland.

The escorts fought back, assisted by land-based aircraft; but ships ahead of, astern of, and to starboard of Sapelo were hit.

In September, she shifted south to the Caribbean and through the fall shuttled petroleum products from Aruba and Curaçao to the east coast.

That summer, she again crossed the Atlantic; and, in September, she resumed operations along the east and gulf coasts, to Bermuda, and into the Caribbean which she continued until the end of World War II.
