The originating agency is the Central Intelligence Agency, the document distribution date is December 20, 1973, and the incident location is the USSR. The report contains a first-hand source account of an unidentified luminous aerial object observed at a Soviet weapons testing facility in late summer 1973.[^1][^2][^3]\n\n<PDF src=\"https://www.war.gov/medialink/ufo/052226/release_02/documents/CIA-UAP-D001_Intelligence_Information_Report_USSR_1973.pdf\" />\n\n## Provenance and Chain of Custody\n\nThe document carries the classification marking CONFIDENTIAL with the warning notice \"Sensitive Intelligence Sources and Methods Involved.\" It is designated report number FIK K-311/01638-77, also referenced as 3915084-/3, and originated within the CIA Directorate of Operations. The approved release date is 2026, and the cover sheet notes the document is exempt from the General Declassification Schedule under Executive Order 11652, with automatic declassification described as impossible to determine.\n\nThe cover sheet records that information was obtained through human intelligence (HUMINT) acquired via Germany from a former Soviet citizen. The source's specific service or employment background is partially redacted in the declassified version. The date-of-information span runs from November 1972 to November 1973, and distribution of the report was dated December 20, 1973.\n\nUpon distribution, the report was disseminated to a wide set of agencies and offices: the State Department, Defense Intelligence Agency (DIA), National Security Agency (NSA), Army, National Military Intelligence Center (NMIC), Intelligence Analysis Service (IAS), Office of Strategic Research (OSR), Office of Management and Information (OMI), Office of Strategic Operations (OSO), Operations Control Room (OCR), United States Information Agency (USIA), Federal Bureau of Investigation (FBI), and Special Weapons Service (SWS). The breadth of this distribution reflects the range of potential intelligence value the reporting was judged to hold at the time of dissemination.\n\nThe document carries the standard IIR disclaimer: \"THIS IS AN INFORMATION REPORT, NOT FINALLY EVALUATED INTELLIGENCE.\" This caveat is analytically significant -- the contents represent raw HUMINT collection and should not be read as finished, corroborated, or assessed intelligence.\n\n## Subject: The Sary Shagan Weapons Testing Range\n\nThe central subject of the report is the Sary Shagan Weapons Testing Range in the Soviet Union. The report's own summary describes its scope as \"limited information on the Sary Shagan weapons testing range, to include facilities, work areas, security fencing, the regional headquarters (V/Ch 03080), and a warhead checkout unit (V/Ch 03142).\" Beyond facility information, the report covers two Soviet missile warhead systems, hearsay regarding laser research, and the UAP observation documented in section 14.\n\n### System-75 (SA-2) Warhead Intelligence\n\nAt Site 4 of the range, the source reports that warhead checkout operations were conducted for System-75 missiles -- identified in Western nomenclature as the SA-2 surface-to-air missile. The source provided specific physical descriptions of the warhead components:\n\n- Each warhead assembly contained approximately 100 grey cassettes measuring 30 x 7 centimeters\n- Each cassette housed approximately 200 to 300 metal balls, referred to in Russian as *shariki*\n- Each metal sphere measured no more than 1.5 centimeters in diameter\n\nThese specifications are consistent with fragmentation warhead designs characteristic of Soviet air defense systems of the period. The level of detail suggests a source with direct access to the physical inspection or handling of warhead components.\n\n### System-300/Aldan (ABM-1 GALOSH) Warhead Intelligence\n\nThe report also covers a more advanced weapons system designated by the source as System-300 and/or Aldan. A field analyst comment notes that the source \"did not know if Aldan was another name for the System-300 missile, or if they were two similar missiles.\" Later intelligence analysis identifies this system as the ABM-1 GALOSH, the Soviet Union's principal anti-ballistic missile interceptor during the 1970s.\n\nAfter warhead checks at Site 4, System-300/Aldan warheads were transported to Site 3 for launching and testing. The source reported that, according to rumor, the missile was intended for antimissile defense -- *protivo raketnaya oborona* (PRO) in Soviet military terminology, consistent with the ABM-1 designation.\n\nThe source described the warhead's physical configuration as:\n\n- Length approximately two meters\n- Diameter 80 to 100 centimeters\n- Weight approximately 400 kilograms\n- An unspecified number of black cassettes measuring 45 x 12 centimeters each, containing an unknown number of metal balls\n\nA field comment clarifies the source's limitations on nuclear matters: \"Source had no knowledge regarding nuclear warheads. He opined that all systems could be equipped with nuclear warheads. However, Source stated all work done by his department was basically experimental (*opytnaya*).\" This is explicit: the source's inference that systems could carry nuclear warheads is unconfirmed and speculative on his part.\n\n### Alleged Laser Research\n\nA brief entry addresses laser weapons testing: \"According to hearsay, experiments involving laser weapons were being conducted at an unknown location at the range. Supposedly, the tests involved powerful antennas (no further details).\"\n\nThis entry encapsulates the full extent of available intelligence on this subject. The location within the range is unidentified, the mention of \"powerful antennas\" is unexplained and provides no technical basis for assessment, and the sole source of the information is hearsay. No corroborating detail was available.\n\n## The Section 14 UAP Account\n\nSection 14 of the report documents the only first-hand observation in the document, and the only directly UAP-relevant content.\n\nIn late summer 1973, during evening hours, the source was at Site 7 of the Sary Shagan range. He had been indoors watching a televised sports competition between Canada and the USSR when he stepped outside for air. At that point he observed what the report describes as an \"unidentified sharp (bright) green circular object or mass in the sky.\"\n\nThe object was positioned to the west of Site 7 at a sighting angle of approximately 70 degrees from the observer's position. The source was unable to determine the object's altitude with precision, though he believed it was above cloud level, noting there were no clouds present at the time.\n\nThe observation unfolded in a documented temporal sequence:\n\n1. Initial observation: a bright green circular object or mass\n2. Within 10 to 15 seconds: the green circle \"widened\"\n3. Shortly after: \"Several green concentric circles formed around the mass\"\n4. Within minutes: \"The coloring disappeared\"\n\nNo sound accompanied the phenomenon at any point -- the source noted there was no sound \"such as an explosion\" associated with the event.\n\nField analyst comments document the limits of the source's account. The source had no opinion as to what the phenomenon was. No rumors or discussion circulated among Soviet personnel at Site 7 following the incident. The source could not estimate the diameter of the object. No follow-up investigation or formal reporting within the Soviet facility is documented.\n\nThe analyst's note on size reads: \"Although there were no clouds in the sky that evening, Source believed that the green mass would have been higher than cloud level. Source could not estimate the diameter of the object.\"\n\nThe apparent absence of subsequent discussion or concern among Soviet personnel at an active weapons testing range is notable but unexplained. It may reflect that the phenomenon was considered routine, was classified at a level above the source's awareness, or simply generated no concern.\n\n## Intelligence Context\n\nThe Sary Shagan range was a strategically significant Soviet facility, primarily used for testing and developing anti-aircraft and anti-ballistic missile systems. CIA collection against it during the early 1970s was an intelligence priority given the strategic competition over missile defense. A HUMINT source with site-level access and knowledge of physical warhead configurations would have been a valued asset.\n\nThe UAP observation occupies a single section of a broader technical collection report. It appears to have been included as an anomalous data point encountered in the course of routine technical reporting rather than as a primary collection objective. The document provides no indication that the CIA assessed or followed up on the observation.\n\n## What The Record Supports\n\nCIA-UAP-D001 preserves a Cold War-era CIA intelligence report that includes a single HUMINT source account of an unidentified aerial phenomenon observed at a Soviet weapons testing facility in late summer 1973. The source described a bright green circular mass that widened and formed concentric circles before disappearing over several minutes, without sound.\n\nThe record establishes that the CIA collected and formally documented the observation within an IIR disseminated to senior national security consumers in December 1973. It does not identify the phenomenon. The report contains no sensor data, imagery, or corroborating witness accounts. The sighting remained unresolved at the time of collection and no subsequent analytical assessment of the UAP observation appears in the declassified record. The technical sections on warhead specifications and missile systems represent separately evaluable intelligence on Soviet weapons programs, but no connection between those systems and the UAP observation is stated or implied in the document.\n\nThe phenomenon is unresolved and remains unidentified.\n\n## References\n\n[^1]: [Department of War PURSUE page](https://www.war.gov/UFO/#release)\n\n[^2]: [Department of War PURSUE data file (uap-data.csv)](https://www.war.gov/Portals/1/Interactive/2026/UFO/uap-data.csv)\n\n[^3]: [CIA-UAP-D001, Intelligence Information Report, USSR, 1973 remote release asset](https://www.war.gov/medialink/ufo/052226/release_02/documents/CIA-UAP-D001_Intelligence_Information_Report_USSR_1973.pdf)","readingTime":"8 min read"},"relatedRecords":[],"citation":{"canonicalUrl":"https://disclosdex.com/documents/2026-pursue-release-02-001-cia-uap-d001-intelligence-information-report-ussr-1973","title":"CIA-UAP-D001 Intelligence Information Report USSR 1973","publisher":"Disclosdex","retrievedFrom":"https://disclosdex.com/api/v1/documents/2026-pursue-release-02-001-cia-uap-d001-intelligence-information-report-ussr-1973","license":"CC-BY-4.0"}}
