Arriving there on the 23d, Alcona took on board cargo and got underway on the last day of October to commence operations supplying American advanced bases in New Guinea and later, in the Philippines which would keep her occupied for the rest of the war.

After discharging her cargo, Alcona then proceeded via Hollandia, New Guinea, to Mios Woendi, in the Padaido Islands, where she spent Christmas before getting underway on 27 December for Australia.

[3] Alcona reached Brisbane, Australia, on 4 January 1945 and loaded cargo there until the 10th when she weighed anchor to head for the advanced base at Milne Bay, New Guinea.

Upon arrival back in the Philippines, Alcona discharged her cargo into tank landing craft (LCT's) off the former American naval base at Cavite.

[3] Alcona had transported another consignment of cargo to the Philippines by mid-July and had completed her task at Subic Bay by 8 August, two days after the first atomic bomb had been dropped on the city of Hiroshima.

[3] Alcona conducted another voyage from Brisbane to the Philippines and then, after undergoing repairs in the advanced base sectional floating drydock ABSD-5, proceeded to Samar on 12 November.

[3] Initially, it had been planned to decommission Alcona at Norfolk so that she might be returned to the War Shipping Administration and laid up in the James River to await further disposition.

However, on 18 April 1946, Captain Richard H. Cruzen, prospective commanding officer of an Arctic exercise, code named "Nanook" requested that Alcona be assigned to his task force.

Later, however, as the scope of operations expanded to encompass the establishment of advanced weather stations in the Canadian Arctic and in Greenland, it became evident that an increased lift capability was called for.

During her time at Boston, Task Force (TF) 68-consisting of Norton Sound, Northwind, Alcona, Beltrami, Atule, and Whitewood, was activated on 15 June for "Nanook".

Finally, after being held at Boston to load delayed supplies for the Weather Bureau, Alcona, the last ship of the "Nanook" force to get underway, sailed at 13:10 on 18 July for Greenland.

Favorable ice conditions and good visibility made the passage possible and enabled Alcona to anchor in North Star Bay, off Thule, at 19:28 on 27 July.

On the 22d, Alcona had helped cement American-Danish ties when the Royal Danish Navy surveying tender Ternan ran aground on the rocks at the entrance to North Star Bay at 03:25.

She suffered the least of the three ships caught in the gale, Whitewood was forced to heave to in heavy seas for 36 hours in winds that sometimes reached 55 kn (102 km/h; 63 mph); Northwind rolled and pitched, giving all hands a rough ride.

Although the storm put Alcona a day behind her schedule, she reached Arsuk Fjord without mishap on 15 September and that morning transferred Quartermaster Richard B. Anderson, Royal Danish Navy, to Sorrell, off Simiutak Island.

A Danish surgeon subsequently sent a dispatch to the Navy expressing his appreciation for the "outstanding brain surgery and exceptional medical job performed" by Alcona's doctor.

From Bayonne, she carried out a busy schedule of cargo-carrying operations as a unit of the Atlantic Fleet's Service Force through the summer of 1947, numbering Argentia; St. John's, Newfoundland; Bermuda; San Juan, Puerto Rico; and Guantánamo Bay as her ports of call.

[3] Underway shortly after noon on the following day, Alcona was proceeding to San Juan, Puerto Rico, when, at 01:40, she collided with the Pacific Tanker Line's vessel, SS York.

About 03:23, "after determining that the extent of damage was such that it was safe to proceed," Alcona moved slowly ahead, shaping course for Norfolk, with a watch on the foc'sle to take soundings in the ship's number one hold every 15 minutes.

[3] Departing Norfolk on 6 July after operating locally in the waters of the Tidewater region, Alcona sailed for Earle, New Jersey, reaching that destination the following day to load a cargo of explosives and pyrotechnic materials.

subsequently discharged her cargo at Trinidad, British West Indies, 8 to 28 August; and at Coco Solo, 17 to 25 September, before arriving back at Leonardo, New Jersey, on 3 October.

Besides ranging from Bermuda to Argentia and from Guantanamo Bay to the Panama Canal Zone, she made a second transatlantic voyage to carry cargo to Casablanca in the autumn of 1950.
