Assigned to Escort Division 24, DE 179 McAnn sailed for the Caribbean 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 which had splashed off the Brazilian coast the day before. McAnn arrived Recife 16 March.

Between 2 and 12 April McAnn cruised to Trinidad in the screen of convoy JT 27, and during the next 3 months she completed three additional escort runs between the Caribbean and Brazil. She completed this duty 12 July and 4 days later departed Recife as screen for Memphis (CL‑13). She cruised the South Atlantic in search of German submarines until returning to Recife 30 July. McAnn underwent an upkeep and then steamed to Natal arriving 10 August.

She decommissioned there 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 Bracui (D‑23). She served on loan with Brazilian Navy until 30 June 1953 when she was retransferred to Brazil, permanently, under the Mutual Defense Assistance Pact. Into 1969, McAnn continued to serve as Bracui with the same efficiency and preparedness to duty that she did when she was a unit of the U.S. Navy.
