View original document (8.7 MB)

According to Department of War records released under the PURSUE archive on May 8, 2026, a document titled “DOW-UAP-D49, Launch Summary, Vandenberg AFB, 2000” provides a historical registry of all major launch operations conducted from Vandenberg Air Force Base, California, from its first launch on December 16, 1958, through February 3, 2000. The official description from the Department of War summarizes the report as a record of launches occurring at the base between 1958 and 2000, with the incident date listed as February 3, 2000, and no specific incident location provided.

Document Contents and Structure

The document, released as a PDF from the war.gov domain, is a comprehensive launch summary book prepared by the 30th Space Wing Office of History. It includes a distribution list of 30 recipients, ranging from Headquarters USAF and NASA to contractors such as Boeing Defense & Space Group, Aerospace Corporation, and Jet Propulsion Laboratory. The foreword, signed by Jeffrey Geiger of the Office of History, states: “This is the official registry of all major launch operations conducted from Vandenberg Air Force Base, California. The vehicles are presented in chronological order beginning with the first launch on 16 December 1958. Launch dates reflect Vandenberg local time.”

The document is organized into two matrices: “ANNUAL LAUNCH SUMMARY BY BOOSTER” and “ANNUAL LAUNCH SUMMARY BY COMMAND,” along with a “LAUNCH FACILITY GUIDE” and a “GLOSSARY.” The foreword notes that cumulative numbers reported by booster and command “represent only Vandenberg operations” and do not include, for example, “Titan IV launches conducted on the East Coast at Cape Canaveral, Florida.” The glossary, which is extensive, defines acronyms related to missile and space programs, including terms such as ICBM (Intercontinental Ballistic Missile), ABRES (Advanced Ballistic Reentry System), DMSP (Defense Meteorological Satellite Program), and ERCS (Emergency Rocket Communications System).

Agency Context and Release

The document was released by the U.S. Department of War as part of the PURSUE archive, a government initiative that has made a number of UAP-related records publicly available. The Department of War’s role in this release is notable, as the document originates from the 30th Space Wing, which is part of the U.S. Air Force. The document’s official summary offers limited detail beyond its description as a launch summary, and the specific incident date of February 3, 2000, appears to correspond to the “as of” date listed in the distribution list, rather than a particular launch event. The document does not explicitly reference any unidentified aerial phenomena or anomalous events, instead focusing on routine launch operations and historical records.

Per a Wikipedia summary of unidentified flying objects, “An unidentified flying object (UFO) is an object or phenomenon seen in the sky but not yet identified or explained.” The Wikipedia entry notes that the term was coined when U.S. Air Force investigations into flying saucers found too broad a range of shapes reported to consider them all saucers or discs, and that UFOs are also known as unidentified aerial phenomena or unidentified anomalous phenomena (UAPs). The entry further states that “upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.” This context is relevant as the PURSUE archive aims to provide government records that may relate to such unexplained phenomena, though the launch summary itself does not directly address sightings or anomalies.

What Remains Unanswered

The document’s release raises several questions. While it provides a detailed historical record of launches at Vandenberg AFB, it does not explain why it was categorized under the UAP files of the PURSUE archive. The official description is vague, offering no connection to unidentified objects or anomalous events. The glossary includes terms such as “Ballistic Missile Reentry System” and “Advanced Maneuverable Reentry Vehicle,” which suggest a focus on missile testing and space operations, but no specific incidents involving UAPs are mentioned. Readers should watch for future PURSUE releases to see if additional documents provide context for this launch summary’s inclusion in the UAP archive, or if it serves as a baseline record for comparison with other, more directly UAP-related files.
