# Farewell Dossier **Entity class:** Intelligence collection and technology-denial episode **Domain:** Cold War intelligence / technology transfer **Doc Type:** Developed Event Node **Maturity:** Historical ## Definition The **Farewell Dossier** was the body of material supplied to French intelligence by KGB officer Vladimir Vetrov beginning in 1981. It exposed Line X personnel and Soviet acquisition requirements for Western technology. ## Denial-War Context The dossier gave Western governments a map of Soviet technology procurement. U.S. policy used that visibility to restrict, monitor, and, according to published accounts, manipulate acquisition channels. Claims that altered pipeline-control software caused a 1982 Siberian explosion remain disputed and therefore occupy a lower evidentiary tier than the documented espionage and counterintelligence operation. ## Evidence Ledger - **Established:** Vetrov supplied extensive Line X identities and technology requirements to France. - **Established:** The material informed allied counterintelligence and technology-denial actions. - **Plausible:** Compromised technology supplied through exposed channels produced specific industrial failures. - **Unresolved:** The pipeline-explosion claim. Promotion requires contemporary operational records or corroborated Soviet technical files; demotion requires complete incident records excluding doctored control software. ## Sources / Provenance - CIA, [“The Farewell Dossier” historical account](https://www.cia.gov/resources/csi/studies-in-intelligence/archives/vol-39-no-5/the-farewell-dossier/). - [[articles/A History of Machine Intelligence|A History of Machine Intelligence]]. ## Relationships - **Exposed:** Soviet technology-acquisition networks responding to [[wiki/CoCom|CoCom]]. - **Belongs to:** [[wiki/Denial Wars|Denial Wars]].
