After shakedown in the Chesapeake Bay, Montague proceeded to Hawaii, arriving Pearl Harbor on 10 June 1945.

While there we were practicing "hitting" the beach with full crew and equipment on our 'Higgins boat' in preparation for the invasion of Japan.

The USS Montague operated off the east coast of the United States for the next two years, and participated in training exercises in the Caribbean.

Getting underway from Norfolk, Virginia, on 3 January 1948, she sailed for duty with the 6th Fleet, helping to stabilize the postwar situation in the Mediterranean.

Receiving orders to support United Nations action in Korea in August, she transited the Suez Canal, arriving at Kobe, Japan on 9 September 1950.

The USS Montague was decommissioned on 22 November 1955, was berthed at Mare Island, California as a unit of the Pacific Reserve Fleet and was transferred to the Maritime Administration on 29 January 1960.

Berthed as a unit of the National Defense Reserve Fleet at Olympia, Washington, the ship was sold for scrapping on 12 March 1971 to the West Waterway Lumber Company.
