Chadwell CIA memorandum on UFOs (Dec 1952) + Bedell Smith memo to the NSC
- Author: H. Marshall Chadwell, Assistant Director, CIA Office of Scientific Intelligence (OSI), to Director of Central Intelligence Gen. Walter Bedell Smith. Dated December 2, 1952 (following an earlier Sept 24, 1952 Chadwell memo on the same subject).
- Significance: a contemporaneous, authentic, declassified CIA assessment treating UAP as a national-security concern; it led directly to the Robertson Panel (Jan 1953) and the CIA’s subsequent debunking posture. Referenced in the AARO 2024 historical review (historical-review-vol1) and cited by Richard Dolan as one of the genuinely authentic documents in the record.
- Provenance: declassified via the CIA FOIA reading room (CREST). The excerpts below are the well-attested, load-bearing passages (cross-checked across the CIA reading-room release, the Robertson Panel literature, and the AARO review); this is a curated excerpt of the key passages, not a full-document OCR. Captured 2026-05-29.
Chadwell to the DCI (Dec 2, 1952) — key passages
“…reports of incidents convince us that there is something going on that must have immediate attention.”
“Sightings of unexplained objects at great altitudes and traveling at high speeds in the vicinity of major U.S. defense installations are of such nature that they are not attributable to natural phenomena or known types of aerial vehicles.”
Chadwell recommended that the National Security Council be informed and that a coordinated scientific effort be initiated to study the phenomena — the recommendation that produced the Robertson Panel in January 1953.
DCI Walter Bedell Smith to the Executive Secretary, National Security Council (Dec 1952)
“It is my view that this situation has possible implications for our national security which transcend the interests of a single service. A broader, coordinated effort should be initiated to develop a firm scientific understanding of the several phenomena which apparently are involved in these reports, and to assure ourselves that the incidents will not hamper our present efforts in the Cold War or confuse our early warning system in case of an attack.”
Reading note: these documents establish official national-security concern and a coordinated study/secrecy response in 1952 — not extraterrestrial origin. That is exactly the distinction Dolan draws (the documents prove “a national security problem,” not “aliens”), and the framework-correct way to weight them: authentic evidence of government concern and management, agnostic on the nature of the phenomena.
