Office of the Director of Naval Intelligence

The Office of the Director of Naval Intelligence (ONI) was established in 1882, making it the United States Navy's oldest intelligence organization. Its original mission focused on collecting and analyzing information about foreign naval developments, capabilities, and emerging maritime technologies. Over time, ONI expanded its role to include counterintelligence, cryptology, and support to fleet operations during both World Wars and the Cold War. Today, ONI remains a vital component of naval operations, providing crucial intelligence to support U.S. naval and joint force missions worldwide.
