What was reported

A short CIA briefing paper prepared for Walter N. Elder (Executive Assistant to the DCI) on the same November 1964 Puerto Rico incident as CIA-UAP-D022. It states that on November 19, the USS Gyatt's radar picked up a high-speed, high-altitude target that closed rapidly on a fighter from astern; a Crusader pilot in full moonlight and good visibility identified the object as delta-shaped, about the size of a jet fighter, and the Gyatt confirmed the track with motion pictures of the radar scope, estimating speed in excess of Mach 3. It notes ONI had no further information and had been asked to report similar future incidents, and mentions the Gyatt's advanced surface-to-air missile equipment for context.

What officials concluded

Unresolved

ONI had no further information on the object beyond the radar/visual data reported and requested notification of similar future incidents.

Why this rating Same evidentiary basis as CIA-UAP-D022: independent radar-with-film-record and pilot-visual corroboration of an extreme-speed contact; moderate rather than strong because the observation window was brief and no conventional-explanation analysis is included in this short briefing note.

    CIA-UAP-D022, Unidentified Flying Object Reported near Puerto Rico, 1965

    CIA OXCART-program memoranda (dated Feb 1, 1965, discussing a Nov 18-24, 1964 series of events) exchanged between the Assistant Director for Special Activities and the Assistant Director for Scientific Intelligence regarding a radar/visual UFO incident near Puerto Rico. A Navy F-8 Crusader pilot observed a delta-shaped object about the size of a jet fighter, visually estimating its speed at Mach 3; a corresponding AN/SPS-49 radar track from the USS Gyatt independently measured the object at 3,800 knots (~4,373 mph). CIA's own internal correspondence states the Office of Naval Intelligence was 'finally convinced' the object was NOT a YF-12A (OXCART/A-12-derivative) aircraft, explicitly ruling out the classified domestic program as an explanation.

  • Unverified

    A Crusader pilot in full moonlight and good visibility identified the object as delta-shaped, about the size of a jet fighter, while the USS Gyatt's radar independently confirmed the track on motion-picture film.
