Declassified Navy UFO Cases: From 1952 Mainbrace to the Pebble Beach Underwater Dome Incident

Richard Dolan uncovers the U.S. Navy’s forgotten UFO and USO history, from multiple dramatic carrier encounters aboard the nuclear-armed USS Franklin D. Roosevelt during 1952’s massive NATO Operation Mainbrace to the shocking 1992 Pebble Beach Dome Attack. In this eye-opening historical analysis, Dolan examines four well-witnessed UFO/USO incidents involving allied forces in the North Sea, including Lt. John W. Kilburn’s confirmed spinning disc sighting. He explores how these events occurred amid Cold War nuclear tensions and what they reveal about possible non-human interest in U.S. naval capabilities. The video also details the disturbing April 2, 1992, Pebble Beach, California USO case: a glowing green underwater dome that projected a beam of light and emitted a high-pitched ringing noise, triggering panic and lasting trauma for a mother and daughter who reported it to the National UFO Reporting Center. Drawing on decades of research, Dolan connects these “lost” cases to the broader pattern of government secrecy, credible military witnesses, and the push for UFO/UAP disclosure. For over 25 years, Richard Dolan has been a leading UFO researcher and historian. Author of UFOs and the National Security State (2 vols.), A.D. After Disclosure, UFOs for the 21st Century Mind, The Alien Agendas, and A History of USOs.
