Although her construction was suspended in August 1945 after the war's end, the ship, renamed Tonti after an early explorer of North America, was completed in December 1945.

Tonti (AOG-76)—originally slated for use by the British under the terms of the Lend-Lease Program— was laid down under a United States Maritime Commission contract (MC hull 2648) as Tavern on 16 May 1945 by the Todd-Houston Shipbuilding Corporation of Houston, Texas.

She plied the waters of the Atlantic, the Caribbean, and the Gulf of Mexico, ranging as far north as the Labrador Sea.

In July 1960, she was returned to the custody of the United States Maritime Administration (a successor to the Martitime Commission) and placed in the National Defense Reserve Fleet.

On 13 January 1965, the ship was transferred to the Colombian Navy under the "grant aid" program and served as Mamonal (BT-62) until 1975 when she was scrapped.
