Construction and commissioning

Tollberg was laid down as the Rudderow-class destroyer escort USS Tollberg (DE-593) on 30 December 1943 by Bethlehem-Hingham Shipyard, Inc., at Hingham, Massachusetts, and was launched on 12 February 1944, sponsored by Mrs. Maynard W. Tollberg. The ship was reclassified as a Crosley-class high-speed transport and redesignated APD-103 on 17 July 1944. After conversion to her new role, she was commissioned on 31 January 1945.

Pacific War

Tollberg stood out of Boston, Massachusetts, on 18 February 1945 for shakedown training off Bermuda. She left Bermuda on 9 March and arrived at Hampton Roads, Virginia, on 11 March.

On 25 March, Tollberg got underway to escort attack cargo ship Rankin to the Panama Canal Zone. Tollberg transited the Panama Canal on 31 March and on 1 April proceeded independently to California. She reached San Diego, California, on 9 April and, on 15 April, departed for Hawaii.

Tollberg arrived at Pearl Harbor, Territory of Hawaii, on 22 April, but left again on 4 May and proceeded via Eniwetok to Ulithi Atoll. She got underway on 31 May with destroyer escort Cross to escort the landing craft repair ships Poseidon and Minotaur and tanker Moose to Okinawa, where the Okinawa campaign was in progress. She arrived at the Hagushi beach area on 4 June and was assigned to picket duty in the antiaircraft and antisubmarine screen. Tollberg had only one opportunity to fire her guns at the enemy, at a distant Japanese aircraft.

On 8 August, Tollberg and destroyer escort Abercrombie joined battleships California and Nevada to screen them on a voyage to the Philippine Islands. On 9 August, Tollberg rescued a pilot from California whose float plane had swamped while taxiing in to be picked up. The warships arrived at Leyte in the Philippines on 11 August, and Tollberg remained there until 20 August. World War II ended during her stay at Leyte with the surrender of Japan on 15 August.

Postwar

Tollberg departed the Philippines on 20 August to escort a convoy to Okinawa and returned to Leyte on 29 August. Between 20 September and 3 October, she escorted Transport Squadron 14 to Wakayama Bay, Japan, and back to Leyte. On 2 November, she left Manila, Luzon, to carry passengers to Okinawa and, after escorting amphibious force command ship Estes to Shanghai, China, disembarked them at Buckner Bay, Okinawa, on 7 November. On 12 November, she was back at Manila. Between 24 and 26 November, she embarked 156 passengers at Samar in the Philippines for passage to the United States East Coast.

Departing Samar on 27 November, Tollberg called at Eniwetok, Pearl Harbor, San Diego, and the Panama Canal Zone before arriving at Norfolk, Virginia, on 30 December. She remained at Norfolk until 26 March 1946, when she headed for the West Indies. After two months in the Caribbean, she was at the New York Naval Shipyard in Brooklyn, New York, from 20 May to 24 July. She then entered the Charleston Naval Shipyard at Charleston, South Carolina, for preservation work which continued from 26 July to 12 November. Tollberg then moved on to Green Cove Springs, Florida, arriving there on 13 November.

Decommissioning and disposal

Tollberg was decommissioned at Green Cove Springs on 20 December 1946 and entered the Atlantic Reserve Fleet on the St. Johns River there. In September 1959, she was towed from Mayport, Florida, to Sabine Pass, Texas, and laid up with the Texas Reserve Group of the Atlantic Reserve Fleet.

Tollberg was stricken from the Navy List in November 1964

Colombian Navy service

Tollberg was transferred to Colombia under the Military Assistance Program on 14 August 1965. She served in the Colombian Navy as ARC Almirante Padilla (DT-03) until stricken and scrapped in 1973.
