USS Marts (DE-174)

USS Marts (DE-174) was a Cannon-class destroyer escort built for the United States Navy during World War II. She served in the Atlantic Ocean and provided escort service against submarine and air attack for Navy vessels and convoys.

Marts was named in honor of Alvin Lee Marts who earned the Navy Cross for his heroic efforts during the Battle of Tassafaronga. The ship was laid down by Federal Shipbuilding & Dry Dock Co., Newark, New Jersey, on 26 April 1943; launched on 8 August 1943; sponsored by Miss Betty Marts; and, commissioned on 3 September 1943. Lt. Carl M. Fellows in command.

World War II South Atlantic operations
After shakedown off Bermuda, Marts departed New York on 4 November for convoy escort duty off the Atlantic coast of South America. She reached Trinidad, British West Indies, on 9 November, and during the next five months operated in the 4th Fleet escorting ships between Trinidad and Recife, Brazil. As escort for USS Omaha (CL-4), she departed Bahia, Brazil, on 23 May 1944 and patrolled the mid-Atlantic, south of the Equator, in search of German U-boats, until returning to Bahia on 5 June. She made two more patrols during the next month; and, after escorting Omaha to Gibraltar on 13 July, she returned to Recife the 23rd. Between 24 July and 3 August Marts screened the British cable repair ship SS Cambria during repairs on communications cables off the Brazilian coast. Thence, she joined Escort Division 24 on hunter-killer patrols in the Atlantic. Operating with USS Tripoli (CVE-64), she made four offensive ASW patrols out of Recife between 22 August and 12 November. After completing sonar repairs at Bahia, Brazil, she sailed to Trinidad, where she arrived on 5 December to resume convoy escort duty. From 6 to 18 December she screened a merchant convoy to Recife; thence, she continued escort duty between Brazilian Ports and Trinidad until the end of January 1945. Marts joined USS Cincinnati (CL-6) at Bahia on 1 February and escorted the cruiser on patrol in the South Atlantic until returning to Recife on 10 February.

Post-War deactivation and decommissioning
Scheduled for transfer under lend lease to the Brazilian government, she steamed to the Brazilian naval base at Natal on 2 March, and there trained Brazilian sailors. Marts decommissioned on 20 March 1945 and recommissioned the same day in the Brazilian Navy as Bocaina (D-22). On 30 June 1953, she was returned to the United States and simultaneously transferred outright to Brazil under terms of the Mutual Defense Assistance Program. She continued to serve in the Brazilian Navy until struck and scrapped in 1975.
