What did the declassified documents reveal?

This episode presents a declassified Central Intelligence Agency record concerning Communist China’s strategic weapons program, a National Intelligence Estimate dated April fourth, nineteen sixty‑eight. The document is notable because it updates earlier assessments of China’s missile and nuclear capabilities during the height of the Cultural Revolution. The memorandum was released through the Black Vault’s public archive, uploaded from a digitized copy of the original CIA file.

In a January nineteenth, nineteen sixty‑eight speech to representatives of national defense industries, research institutes, and schools, Premier Zhou En‑lai deplored the damage factional strife was causing in military programs. Zhou said that industrial elements were exceptionally disorganized and had ‘fought for four years and two half‑years.’ He named two Red Guard groups identified as contending factions in the Seventh Ministry of Machine Building, which oversees missiles, and said their ministry had been particularly chaotic. We have had difficulty in establishing how serious these disruptions may have been. On the one hand, extraction work, missile launches, and nuclear testing have continued throughout the Cultural Revolution.
