The Office of Naval Intelligence (ONI), established in 1882 as the United States Navy's primary intelligence arm, has long been at the forefront of gathering and disseminating critical maritime information to support national security and operational readiness. During World War II, ONI played a pivotal role in providing detailed recognition guides and technical assessments to Allied forces, enabling effective identification of enemy and friendly vessels amid the chaos of naval warfare. Renowned for its meticulous research and authoritative publications, ONI's contributions extended beyond the battlefield, shaping postwar naval doctrine and intelligence practices.
