NSA TOP SECRET UMBRA UAP records: full entry breakdown
Compiled from the full 334-page NSA FOIA production released May 18, 2026 by the Disclosure Foundation following a successful appeal of the NSA's initial blanket denial. Each entry below includes the page number from the original production, the classification marking where visible, and the specific language in the document. The Yeates Memo context is established first to explain why these records were kept from the public for 46 years.
Declassified 2009. Public since 2009. The underlying documents it described: classified until 2026.
In 1980 the NSA's Chief Policy Officer, Eugene Yeates, submitted an in camera affidavit to the federal court hearing the FOIA lawsuit. In camera means private: the judge reviewed it, the public did not. The affidavit described what UAP-related material the NSA held and why it should remain classified. The court accepted Yeates' arguments and ruled for the NSA.
The Yeates Memo was itself declassified and made public in 2009. From that point forward, any researcher could read Yeates' description of the NSA's rationale for protecting its UAP records. What Yeates was describing, the actual intelligence reports and collection data, remained classified. The memo functioned as a publicly visible door to a room that stayed locked for another 17 years.
In 2026 the Disclosure Foundation requested the underlying supporting material that Yeates had used to produce his in camera affidavit. The NSA denied the request entirely. On appeal, the NSA's own appeals authority found the blanket denial improper and ordered production. The result is the 334-page release analyzed below.
The Yeates Memo remains available at the NSA's public FOIA reading room. It describes the existence and general nature of NSA UAP holdings without disclosing their specific contents. The 2026 production represents the first time the underlying records the memo was protecting have been partially visible to the public.
These entries document fighter aircraft dispatched in response to unidentified objects. All page citations are from the Disclosure Foundation's public release of the NSA production.
Classification marking: TOP SECRET UMBRA [partially visible].
Entry documents 13 MIG fighter aircraft being dispatched to intercept a single unidentified object. The specific altitude, heading, and outcome of the intercept are redacted. The operational details of what the 13 fighters found, if anything, are not in the visible text. The entry is among the most heavily redacted in the production.
The Disclosure Foundation notes this entry as among those where conventional explanation was not offered in the visible text and where the surrounding operational context is the most substantially removed.
Entry documents 72 unidentified objects tracked simultaneously with a MIG reaction recorded. Altitude noted as exceeding 70,000 feet. Operational details of the MIG response and the outcome are redacted.
Entry documents 23 unidentified objects tracked simultaneously with a MIG reaction recorded, also at altitudes exceeding 70,000 feet. Same redaction pattern as page 63: objects documented, military response documented, outcome and operational details removed.
At least eight entries in the full production document fighter aircraft scrambles in response to unidentified objects. The three entries above are the most specific on numbers of both objects and aircraft. In each case the visible portion of the entry documents the triggering observation and the military response. In each case the redactions remove the operational conclusion.
These entries describe objects whose reported characteristics are not consistent with conventional aircraft or balloons. Direct language from visible portions of the production is transcribed below.
Entry describes an object going up and down vertically. The witnesses assessed it as impossible to be an aircraft. The entry records high speed, white-bluish luminous light, and erratic turning movements. Classification marking partially visible.
Entry is classified SECRET LARUM. LARUM is a codeword compartment within the signals intelligence system. The entry describes a UFO as spherical or disc-like in form with an established color brighter than the sun, with a diameter of one-half the visible size of the moon. The observation was made above cloud cover with specific bearing and azimuth data recorded. The intelligence message format, specific measurement data, and formal codeword classification indicate this is a trained intelligence report, not a civilian sighting narrative.
Entry describes an elongated ball of fire moving at high rate of speed. After covering some distance, the object split into three separate balls of fire. No conventional explanation is offered in the visible text. Surrounding operational context is redacted.
Entry documents an object with luminous radiation of 22 meters extending in a spiral pattern. The object gained altitude without noise. The measurement of 22 meters suggests instrumented or calibrated observation rather than unaided eyewitness estimation. The entry format is consistent with formal intelligence reporting.
Entry documents two yellow lights flying at low altitude. The object changed heading from north to west. No noise was recorded. Multiple entries in the production describing similar silent direction changes are also redacted at the points where the analysis of what the object was would appear.
Entry is classified SECRET SAVIN. SAVIN is a separate codeword compartment within the SIGINT system. The entry documents multiple independent observers reporting the same object: silent, direction-changing lights observed at approximately 2,000 feet distance. The structured format records specific times, specific bearings, and corroborating observers. This is the format of trained intelligence reporting, not a casual civilian account.
The multi-witness, multi-observer format of this entry is significant. SIGINT channels are not designed to collect and retain individual civilian sighting reports. An entry in NSA SIGINT files with multiple corroborated observers, specific measurement data, and a codeword compartment marking indicates this was treated as an intelligence matter requiring controlled handling.
The 334-page production does not redact uniformly. The Disclosure Foundation's initial review identified a consistent pattern across the full document set. Entries carrying the assessment probably balloons retain their analytical context: the times, altitudes, headings, and basis for the assessment are visible. Entries describing objects with disc-like shapes, extreme speed, luminous emissions, vertical oscillation, silent directional change, and military intercept responses have those same categories of detail removed.
The NSA is asserting exemptions under Executive Order 13526, which governs classified national security information and permits continued protection of intelligence sources and methods and sensitive foreign relationships, and Public Law 86-36 / 50 U.S.C. 3605, the statute specifically created to protect NSA organization, functions, and sensitive sources and methods.
The Disclosure Foundation has stated that when an entry describes an object at 95,000 feet that triggered a military fighter response and the operational details remain classified more than four decades later, national security cannot serve as an unexplained incantation. The organization has stated its legal team is reviewing the asserted exemptions and will challenge those it determines to be improper given the age of the records.
The following categories of material are either entirely withheld or substantially redacted in the 2026 production:
The operational conclusions of military scramble responses, including what the 13 MIG fighters dispatched on page 236 found. The full analytical assessments for the anomalous object entries on pages 329, 330, 333, and 322. The foreign intelligence source and collection method details in the SECRET LARUM (page 329) and SECRET SAVIN (page 315) entries. The full contents of entries describing objects at altitudes above 70,000 feet. The congressional UAP briefings that federal law required agencies to provide to the intelligence committees, which the Disclosure Foundation has separately targeted through Mandatory Declassification Review requests.
The Disclosure Foundation's MDR requests targeting congressional UAP briefings are pending as of the date of this compilation. If successful, those requests would produce the executive branch's own curated summaries of UAP knowledge delivered to Congress in classified sessions, a different and potentially more significant category of record than the raw intelligence reports in this production.
The Interference begins with a patent. US3951134, filed in 1974, describes a device for remotely monitoring and altering human brain waves without physical contact. The patent is real. The USPTO granted it. The documents on this site are what precedes it.
The fiction begins exactly where the public record stops answering questions.
