Sailors aboard the Midway-class aircraft carrier USS Franklin D. Roosevelt (CVB-42) take part in an informal shipboard ritual, likely a variation of the traditional 'shellback' initiation performed when a Navy vessel crosses the equator. Photographs like this one, often annotated by their owners with humorous captions, document the camaraderie and morale-building traditions of enlisted life aboard America's post-World War II carrier fleet.
