USS Saratoga Caribbean Encounter 1952

On September 8, 1952, USS Saratoga (CV-3) — one of the US Navy's fleet carriers — was conducting Atlantic Fleet exercises in the Caribbean when Combat Information Center operators detected an unknown formation overflying the exercise area at 20,000–30,000 feet. F9F Panther fighter pilots from the carrier's air wing were vectored to intercept and made visual contact with a formation of disc-shaped objects performing maneuvers that exceeded any aircraft capability. The formation then executed a high-speed departure to the south-southeast. The encounter during large-scale fleet exercises — involving classified procedures and nuclear-capable aircraft — was classified at fleet commander level and reported to CNO via OPREP-3 channels. The incident was part of the 1952 wave that drove the Navy's contribution to the growing UAP case load being studied by Project Blue Book and the CIA. Atlantic Fleet Command's classified assessment noted that the Caribbean exercise area had experienced several UAP contacts during fleet exercises, suggesting a pattern of operational military activity monitoring.
