[2] Designed to make emergency repairs in forward areas to battle-damaged ships, Nestor left Norfolk 4 August 1944, for Guantanamo Bay, the Panama Canal, and Ulithi, arriving 21 October, to take up her primary mission.

During the next five and a half months she acted as tender to small craft and repaired all types of naval vessels from battleships to LCIs.

Japanese air attacks, often by suicide plane, inflicted heavy damage on the fleet, and Nestor worked round-the-clock, often under fire herself, to help keep the fighting ships in action.

As Okinawa itself became secure, Nestor entered Buckner Bay 10 July, and continued her vital services, which here included the tremendous task of building a cofferdam.

Nestor along with LST-823, LST-826, three floating docks, and some smaller craft, were included in the May batch and were purchased by the Oklahoma-Philippines Company in what was referred to as the "Berry sale".
