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.

Nestor left Ulithi 19 April 1945, for Kerama Retto, seized in the initial phase of the Okinawa campaign to serve as a base for the ships engaged in the main assault.
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 was driven aground by wind and heavy seas in the devastating Typhoon "Louise" of 9 October, and had to be abandoned.
She decommissioned on 29 November, was stricken on 3 January 1946, and her hulk was sold for scrap on 1 May 1947.

In November 1945 the CNO directed that the hulk be sunk or destroyed, but this was not done and she became one of around 15 Okinawa typhoon wrecks that were finally sold for scrap in two batches in May and November 1947 by the State Department's Foreign Liquidations Commission.
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".
The date of her scrapping is not known.
