The 1965 USS Franklin D. Roosevelt UAP Encounter: Declassified Naval Logs of a Mediterranean Observation

Incident Over the Mediterranean

On September 15, 1965, the USS Franklin D. Roosevelt (CVA-42) was engaged in routine carrier operations in the Mediterranean Sea. At approximately 21:00 hours, deck officers and lookouts reported a large, luminous object hovering directly above the carrier's flight deck. The object was described as a 'solid, metallic disc' approximately 50 to 100 feet in diameter, emitting a soft, pulsating orange light. The encounter was witnessed by dozens of personnel, including pilots, radar operators, and the ship's executive officer.

Radar Tracking and Electronic Interference

Shipboard radar systems, specifically the SPS-10 and SPS-37 sets, initially struggled to maintain a lock on the target. Operators reported 'electronic jamming' and 'ghosting' effects on their screens, which ceased only when the object moved away from the carrier. However, the object was tracked by other ships within the strike group, confirming that it was a physical entity rather than a weather phenomenon or an optical illusion. Pilots on the flight deck reported that their aircraft's radio systems experienced significant static and interference while the object was in close proximity.

Project Blue Book Investigation

Following the ship's return to port, the incident was reported to the Office of Naval Intelligence (ONI) and subsequently forwarded to the U.S. Air Force's Project Blue Book. The Blue Book investigators interviewed several key witnesses but were unable to provide a definitive identification. In the final case file, the incident was listed as 'Unidentified,' a rare designation for cases involving multiple military witnesses and hardware. The files noted that the object's ability to shadow a nuclear-capable carrier without detection by early-warning systems was a matter of 'grave concern.'

Modern Context and FOIA Releases

The USS Franklin D. Roosevelt encounter gained renewed attention following FOIA requests filed by researchers at The Black Vault. The released documents show that the Navy took the event seriously, conducting an internal debriefing that was classified for decades. The case is now viewed as a precursor to modern naval UAP encounters, such as the 2004 Nimitz and 2015 Roosevelt incidents, highlighting a long-standing pattern of UAP interest in United States naval carrier strike groups and their nuclear assets.
