In 1950 "Muliphen" transferred to the Atlantic Fleet Amphibious Amphibious Force, based at Norfolk. The following decade she rotated in a steady schedule of Caribbean and Mediterranean deployments. In 1958 she participated in the amphibious landings at Beirut, Lebanon, when a prompt response by the 6th Fleet prevented Communist subversion of Lebanon's government. Continuing similar duty in the 1960s, she also took part in NATO exercises and the training of Naval Academy midshipmen.
