She subsequently served as ARC Córdoba (DT 15) in the Colombian Navy, until 1980; although scrapped, her hull and superstructure were re-erected in a leisure park near Bogotá.

Further amphibious exercises off the U.S. East Coast followed her return from Sixth Fleet duty, and, in August 1952, she conducted her first midshipman training cruise.

Ruchamkin was ordered reactivated in August 1961 to increase the U.S. Navy's troop lift capacity during the Berlin Crisis of 1961.

In November 1963, Ruchamkin's schedule was interrupted for Fleet Rehabilitation and Modernization (FRAM) at the Norfolk Shipbuilding and Drydock Company.

The FRAM II overhaul was completed in June 1964, and she resumed her duties as primary control vessel in ship-to-shore amphibious movements, transport for underwater demolition teams and beach reconnaissance personnel, and antisubmarine warfare screening unit.

In October 1964, Ruchamkin moved east to the coast of Spain, where she controlled the major portion of ship-to-shore movement during Operation Steel Pike I, the largest amphibious exercise since World War II.

In late April and early May 1965, Ruchamkin was called on to assist in the evacuation of civilians from the strife-torn Dominican Republic to San Juan, Puerto Rico.

In October 1966, Hurricane Inez interrupted Caribbean exercises and Ruchamkin, assigned to relief operations, distributed food supplies to survivors in Haiti.

Ruchamkin was turned over to Colombia under the terms of the Military Assistance Program on 24 November 1969, the day of her final U.S. Navy decommissioning.

She subsequently was scrapped, although Córdoba's hull and superstructure were saved and re-erected at the Jaime Duque amusement park at Tocancipá, near Bogotá.
