Ten times, during the intervening 15 years, Shadwell cruised the "middle sea" and visited its ports of call. In 1959, "Shadwell" became the first helicopter-carrying dock landing ship (She had her call letters changed from LSD to LPH when she carried helicopters ). In 1961, she underwent a Fleet Rehabilitation and Modernization (FRAM) overhaul. She was in the Atlantic supporting the Cuban quarantine in October 1962. In February 1964, she participated in the amphibious exercise "Quick Kick V" on the coast of South Carolina. Seven months later, during the passage to her sixth Mediterranean deployment, "Shadwell" took part in Operation "Steel Pike" executed off the coast of Spain. In 1967, she won the Marjorie Sterrett Battleship Fund Award for the Atlantic Fleet. In January 1968, she was in the Caribbean engaged in Operation "Spring Board."
