She spent nearly a year in the South Pacific escorting transports and cargo ships through the New Hebrides and the Solomons, with side trips to Australia.

On 30 December 1944 Greenwood sailed from New Guinea to join Admiral Thomas C. Kinkaid's 7th Fleet at Leyte Gulf.

There she picked up a convoy of supply and troop ships bound for Iwo Jima, still the scene of bloody battle, and sailed 5 March.

Departing the Iwo Jima area 27 March, Greenwood sailed to Eniwetok, where she conducted submarine and anti-submarine training exercises.

Operating out of St. Petersburg, Florida, she continued to conduct reserve training cruises designed to keep the Navy's fighting strength and potential at their peak through the next five years.

She was sold for scrapping on 6 September 1967 to the Lipsett Company (New York City) and was broken up at Kearny, New Jersey (USA).
