Record summary
This file contains Central Intelligence Agency (CIA) memoranda exchanged between the Assistant Director for Special Activities (AD/SA) and the Assistant Director for Scientific Intelligence (AD/SI) regarding an incident allegedly involving unidentified aircraft in the vicinity of Puerto Rico. The AD/SI was then-responsible for analyzing foreign scientific advancements and technological threats, such as Soviet nuclear, chemical, and ballistic missile capabilities. The AD/SA managed the CIA’s classified overhead reconnaissance operations, including the deployment of advanced aircraft like the U-2 and A-12 OXCART. Together, these offices ensured the United States could both gather critical intelligence over contested territories and accurately evaluate the technical capabilities of foreign adversaries during the Cold War. The memoranda refer to an incident on November 19, 1964, in which a U.S. Naval aviator described observing an unidentified object as “delta-shaped, about the size of a jet fighter.” The pilot visually estimated the object’s velocity as Mach 3 (approximately 2,200 mph). A corresponding track from an AN/SPS-49 radar system aboard a U.S. Navy guided missile destroyer in the area, USS Gyatt, measured the object’s speed at 3,800 knots (approximately 4,373 mph). The memoranda indicate that, in the opinion of the AD/SI, the object was conceivably associated with foreign intelligence gathering activities, citing active missile testing within the AFWR, or Atlantic Fleet Weapons Range, as being an attractive reconnaissance target. The AD/SA and AD/SI also ruled out domestic experimental aircraft, such as the YF-12A OXCART, as a potential attribution.

OSI and OSA, we believe; received similar information regarding a UFO in the vicinity of Puerto Rico during period 18-24 November 1964. As you can see by the cable originated by the Commander, Caribbean Sea Frontier, to Commander in Chief Atlantic Fleet, date time group Ol/2048Z December, CINCLANTFLT was informed that UFO identified by CO Ramey as being YF-12A. We think ONI finally convinced, through our efforts, that UFO in fact not YF-12A or similar category Lockheed Aircraft. 2. Navy has provided, at our request, pertinent traffic on this subject, as well as original radar film, Attachment 1, with accompanying prints of same. Request OSI, possibly in conjunction with OEL, evaluate the radar photography to determine if any further information can be gotten through a thorough scientific analysis of the material relative to a high speed, high altitude UFO. 3. Request on completion of OSI study that the attached documents, film and prints be returned to the TCO/BCO/OSA for return to Navy. ....__i ACK C.
