Editing Secret facilities (section)

== Types ==

=== Public-facing (white world) ===
These facilities conduct [[classification|classified]] activities but are publicly acknowledged. Their locations are known, marked on maps, and sometimes even partially accessible to the public. Examples include [[CIA]] headquarters at Langley and the [[National Security Agency|NSA]] complex at Fort Meade, where vast amounts of [[intelligence collection|compartmentalized HUMINT]] are processed. Despite their transparency in location, unauthorized disclosure of their activities can pose extreme risks.

=== Unacknowledged (grey world) ===
Grey world facilities are those whose existence may not be explicitly denied but whose purpose and operations remain classified. Examples include [[continuity of government]] bunkers, such as [[Site-R]] and the [[Mount Weather Emergency Operations Center]], as well as [[private military contractor|defense contractor]] sites. These locations often support highly sensitive operations, including testing [[emerging technologies]] or facilitating emergency preparedness.

=== Denied (black sites) ===
Black sites operate entirely outside the realm of official acknowledgment. Their existence, activities, and purpose are categorically denied, with extreme measures taken to suppress any unauthorized disclosures. [[Extraordinary rendition]] airfields, covert research and development complexes, and certain [[CIA]] prisons exemplify this category. These facilities are rumored to exist both domestically and internationally, often shielded by [[compartmentalization|compartmentalized secrecy]] and [[plausible deniability]].
