During the period 14 April–30 June 1975, "Tacoma" was overhauled in the Norfolk area. On 3 September, following underway refresher training, "Tacoma" commenced the mission of serving as a training unit for Royal Saudi Navy personnel. That assignment, calling for operations along the east coast of the United States and in the Caribbean, continued until decommissioning. For the next five years, "Tacoma" and "Welch" were a part of the Saudi Naval Expansion Program, training Saudi personnel on shipboard operations cruising along the East Coast and Caribbean. The ships often served as Opposing Forces during training operations with the other fleet units. "Tacoma" was decommissioned on 30 September 1981 at Naval Amphibious Base Little Creek, and at that time, was equipped with a 3"/50 caliber gun mount and a 20 mm aft. On 16 May 1983 "Tacoma" and "Welch" were leased to the Colombian National Armada as fast attack ships ARC "Quita Sueño" and ARC "Albuquerque", and were formally transferred to the government of Colombia on 20 September 1995. Both ships have subsequently been transferred to the Colombian Customs agency.
