Through 1959 and 1963, "Fort Snelling" continued her training operations with marines in the Caribbean and on the Carolina coast. In April 1965, Fort Snelling was ordered to the Dominican Republic as part of a task force which included the USS Boxer (LPH-4), USS Rankin (AKA-103), USS Wood County (LST-1178), USS Ruchamakin (APD-89), USS Yancey (AKA-93) and USS Raleigh (LPD-1). Its main mission along with the task force was to deploy marines to evacuate U.S., Canadian and British citizens. Some 14,000 marines participated. In 1966, while returning from a Mediterranean deployment, "Fort Snelling" was assigned as task group commander of the Navy's Palomares Incident recovery operations. Because of her large well deck, "Fort Snelling" carried the deep diving submarine "Aluminaut". In addition, Fort Snelling also deployed the small submarine Alvin from its flight deck via its cranes. In 1966, she participated in the extraction of U.S. Marines from the Dominican Republican crisis.
