During the Cuban Missile Crisis in the fall of 1962, "Rockbridge" carried reinforcements to Guantanamo Bay and returned to the United States for additional troops, which she held in combat readiness until December. In January 1964 "Rockbridge", along with other ships from Phibron 8, was in Cristobal, Panama during the riots. She spent roughly 45 days tied up at the Coco Solo Naval Air Station. During July, 1966, the transport took part in the production of an amphibious training film, "Boat Group Tactics", filmed in Hampton Roads, Virginia. "Rockbridge" also starred in "The Proud and Profane" and supported the filming of "PT-109". A boat crew from "Rockbridge" was assigned to the film crew to operate the LCVP and Japanese landing craft used in the film.
