Namesake
Donald Roy McAnn was born on 23 June 1911 in Rochester, New York. He enlisted in the United States Navy on 16 August 1932. During the early months of World War II he served on USS Enterprise (CV-6) as a gunner's mate first class. On 26 October 1942 U.S. carrier task forces fought a numerically superior Japanese force in the Battle of Santa Cruz Islands. During the air battle, he took valuable photographs from an exposed position on the forward port .50 caliber gun mount. In addition he rendered assistance to the gun crew and displayed outstanding courage without regard for his own safety. While relieving one of the gunners, he was struck by an exploding bomb fragment and fatally wounded. He was buried at sea. He was posthumously awarded the Navy Cross.

World War II Atlantic Ocean operations
After shakedown off Bermuda, McAnn operated along the east coast from Newport, Rhode Island, to Charleston, South Carolina, until 19 December 1943 when she departed Norfolk, Virginia, on a convoy escort run to the Panama Canal Zone.

Assigned to Escort Division 24, McAnn sailed for the Caribbean on 29 February. Steaming via Trinidad, she joined Convoy TJ-25 on 5 March and screened the ships through stormy seas en route to Recife, Brazil. On the 15th she rescued the entire crew of 10 men from a B-17 Flying Fortress which had splashed off the Brazilian coast the day before. McAnn arrived Recife on 16 March.

Between 2 and 12 April McAnn cruised to Trinidad in the screen of Convoy JT-27, and during the next three months she completed three additional escort runs between the Caribbean and Brazil. She completed this duty on 12 July and four days later departed Recife as screen for USS Memphis (CL-13). She cruised the South Atlantic in search of German submarines until returning to Recife on 30 July.

McAnn underwent an upkeep and then steamed to Natal, Brazil, arriving on 10 August 1944. She decommissioned there on 15 August and was transferred, under lend lease, to Brazil on the same date. She was commissioned in the Brazilian Navy on 16 August as Bauru. She served on loan with Brazilian Navy until 30 June 1953 when she was retransferred to Brazil, permanently, under the Mutual Defense Assistance Pact.
