What did the declassified documents reveal?

China: Nuclear Missile Force Operational Procedures – a declassified Defense Intelligence Agency assessment dated June 1969. The document is notable because it provides a contemporaneous U.S. analysis of the structure, survivability emphasis, and launch doctrines of the People’s Republic of China’s strategic missile force during the late 1960s. It is hosted on the Black Vault archive at archive.org. The assessment was released to the public through a Freedom of Information Act request. The Black Vault entry records the release date as the date of the online posting, and the declassification authority is the Director of the Defense Intelligence Agency. No additional FOIA case number is cited in the archive. The document opens with a background overview. It notes that China’s strategic missile inventory at the time consists primarily of three classes of surface‑to‑surface ballistic missiles. The majority are CSS‑2 mobile intermediate‑range ballistic missiles, with a smaller number of CSS‑3 limited‑range intercontinental ballistic missiles and an emerging CSS‑4 longer‑range intercontinental capability capable of reaching targets throughout the United States and the Soviet Union. Key judgments follow. The assessment states that survivability and retaliation are the principal strategic priorities for China’s nuclear force, derived from Chinese strategic theory and the limited size of the force. Emphasis on survivability is intended to ensure that a portion of the force can escape a pre‑emptive strike and subsequently retaliate against the aggressor’s strategic targets. The document describes the basing modes that enhance survivability. Mobile CSS‑2 IRBMs are deployed on road‑mobile launchers, while the CSS‑3 and CSS‑4 systems employ a combination of hardened silos and rollout‑to‑launch vehicles. Figure 3, referenced in the text, outlines these basing options, highlighting the use of mobile command facilities and hardened primary and alternate command centers to preserve command, control, and communications under hostile conditions. The assessment further notes that China’s strategic rocket force places a premium on launch unit generation, reconstitution, and operations under combat conditions. Training exercises and actual launches have been conducted under increasingly realistic simulated combat environments. The Chinese doctrine includes a no‑first‑use policy and lacks an early‑warning system capable of reliable tactical warning, reinforcing the focus on survivability and assured retaliation. Operational doctrine is detailed in the section on launch planning. The Chinese force favors launch‑in‑waves tactics, a principle justified by technical characteristics of the missile force and by political considerations. Historical Chinese military writings emphasize a pattern of threat, pause, action, pause, and further action as needed. The wave launch approach aligns with this pattern, allowing successive retaliatory strikes to achieve political and…
