She sailed for the Naval Operating Base (NOB), Norfolk, on 24 April, and calibrated her radio direction finder en route.

[2] A little over a half hour after the start of the afternoon watch on 16 May 1944, Zeus got underway in company with the internal combustion engine repair ship Oahu, and the submarine chaser SC-706, their escort.

[2] During the forenoon watch on 6 July 1944, however, an escort on the port side of the convoy obtained a sound contact, the alarm prompting the ships to make an emergency 45 degree turn to starboard at 10:53.

For the remainder of the month, the ship carried out work on a variety of vessels ranging from two submarine chasers (SC-775 and SC-670) to three pontoon barges and a pair of target rafts.

The rest of her time that month continued to be occupied with repairs to 42 ships and small craft that ranged from the heavy cruiser New Orleans, the destroyer escorts Cloues, Parks, Riddle and Fair, and the minesweeper Captivate, to four LCV(P)s and five target rafts.

Zeus shifted to berth 579, still in the waters of Eniwetok's central anchorage, where, outside of a Flash Red that sent her to general quarters (15:53-16:04) on 21 September, she continued her toil, her customers ranging from the minesweeper Vigilance and salvage vessel Preserver to 12 LCV(P)s and three medium landing craft (LCM), one of which belonged to the cargo ship Ascella.

[2] Remaining anchored in berth 579 into the month of October 1944, as the fleet prepared for the return to the Philippine Islands in the invasion of Leyte, Zeus provided repairs to ships and craft that ranged from minesweeper Capable, fleet ocean tug Lipan, and net-laying ship Mahogany to small coastal transports APc-110 and APc-111, the seaplane wrecking derrick YSD-36 and US Army Crash Boat 20989.

Shifting to Eniwetok's south anchorage (berth K-1) at the end of the afternoon watch on 14 October, the battle damage repair ship conducted work on 26 vessels ranging from six 173-foot submarine chasers and three 110-footers, the miscellaneous auxiliary Gemsbok and big harbor tug Oconostota to two US Army crash boats and the Army small tug LT-392, during the second half of the month.

[2] The first half of November 1944 proceeded without incident, Zeus continuing her vital repair work to units of the fleet – three dozen all told—from large to small, including six motor minesweepers and eight 173-foot submarine chasers.

On 17 November, however, an hour before the end of the mid watch, the wind increased in velocity to 15–20 kn (28–37 km/h; 17–23 mph) – the ship would clock those during the rest of the day but occasionally reached 45 kn (83 km/h; 52 mph) for brief periods of time – and by the end of the morning watch (08:00) Zeus, with PC-600, old ocean tug Keosanqua, transport Gemini, and non-self-propelled covered lighter YF-385 moored alongside to starboard at the time—was dragging her anchor.

Zeus employed her engines "to ease [the] strain on the chain" until Gemini's black gang lit off her propulsion plant, permitting her to get underway, too.

[2] The ship's workload clearly reflected the pace of the war, such as the invasion of Luzon, and of the many types and classes of naval vessels involved as the New Year 1945 began.

Two days later, the ship shifted her anchorage from J-3 to L-3, and on 21 April, in compliance with orders from ComServRon 10, reported to Commander Marshalls-Gilberts Area for temporary duty.

In the wake of atomic bombs on Hiroshima and Nagasaki, Japan finally agreed to the terms put forth in the Potsdam Declaration, and indicated its willingness to surrender.

Also during that month, Zeus entered the floating dry dock ARD-30 for a brief period of repairs (22-23 October), returning to berth 552 to resume her work.

[2] Zeus departed Eniwetok a little over an hour into the forenoon watch on 6 December 1945, set course for the west coast of the United States.

[2] Zeus remained at San Pedro through mid-March 1946, spending part of that time providing repairs to a quartet of destroyer escorts – Johnnie Hutchins, Rombach, Gentry and Traw.

Assigned to the 19th Reserve Fleet, Zeus remained at San Diego, ultimately moored at the Naval Repair Base there, for the remainder of her commissioned service.

[2] On 30 August 1946, as she lay alongside the internal combustion engine repair ship Culebra Island, Zeus was placed out of commission and berthed at San Diego with the Pacific Reserve Fleet.
