Shepard's next assignment was to VF-193, a night fighter squadron flying the Banshee, that was based at Naval Air Station Moffett Field, California. The squadron was part of Commander James D. "Jig Dog" Ramage's Air Group 19. Naval aviators with experience in jet aircraft were still relatively rare, and Ramage specifically requested Shepard's assignment on the advice of Elder, who commanded VF-193's sister squadron, VF-191. Ramage made Shepard his own wingman, a decision that would save Ramage's life in 1954, when his oxygen system failed and Shepard talked him through a landing. As squadron operations officer, Shepard's most important task was imparting his knowledge of flying jets to his fellow aviators to keep them alive. He served two tours on the aircraft carrier in the western Pacific. It set out on a combat tour off Korea in 1953, during the Korean War, but the Korean Armistice Agreement ended the fighting in July 1953, and Shepard did not see combat.
