The cruise jacket is one of the Navy's most enduring traditions — a custom commemoration of a specific deployment, worn with the pride of a sailor who was there. This jacket honors USS Enterprise's (CVAN-65) 1964 Western Pacific deployment, when the world's first and most powerful nuclear aircraft carrier patrolled the South China Sea as American involvement in Southeast Asia began to escalate. A Shellback — a sailor who has crossed the equator — earns a place among those who can trace their service to the ancient rites of the sea. Men who wore this cruise jacket carried history on their backs long before the rest of the world caught up.
