What did the declassified documents reveal?

From the Central Intelligence Agency, Office of National Estimates, a declassified memorandum dated June twenty-fourth, nineteen-fifty-five. This document analyzes the People's Republic of China's capabilities for developing an atomic weapons and delivery program. You can find this record at documents2.theblackvault.com. This memorandum, designated C I O one two two eight, was approved for release on May twenty-third, two thousand, under F O I A case R D P seven nine R zero zero nine zero four A zero zero zero two zero zero zero three zero zero one four dash one. The declassification authority is not specified on the document itself. The document is titled, "Chinese Communist Capabilities for Developing an Effective Atomic Weapons Program and Weapons Delivery Program". The problem states: "Assuming an international disarmament plan were adopted and Communist China were excluded, how long would it take Communist China to develop effective capabilities in atomic weapons and weapons delivery, (a) without Soviet assistance, and (b) with Soviet assistance?" Under Assumptions, the memorandum notes: "Although radical technological advances which would substantially reduce the difficulties of producing fissionable material and nuclear weapons could occur within the next ten years, this paper does not consider the chances or the effects of such advances." The document states two notes: "One. This paper is one of the topics of interest to the Stassen Committee. It is based on informal O/S T I and J A E I C contributions. A more technical discussion of the atomic weapons problem is found in the J A E I C Estimate (TOP SECRET, RESTRICTED DATA): 'The Nuclear Weapons Capabilities of Selected Countries in nineteen-sixty and nineteen-sixty-five,' approved by the I A C on twenty-one June nineteen-fifty-five. Two. It has not been coordinated with the I A C agencies." The conclusions state: "One. Communist China almost certainly could not develop significant capabilities for the production of nuclear weapons within the next ten years unless it were given substantial external assistance. Without such assistance, the development of an adequate industrial base and a supply of trained scientific and technical personnel sufficient to support an effective nuclear weapons program would probably take well over ten, and possibly twenty years. Two. The Chinese Communist Air Force with only ten medium bombers, T U dash four, B U L L, has a minimal capability for long-range bombardment. With its force of one hundred fifty jet light bombers, I L dash twenty-eight, B U T C H E R, the C C A F could conduct sustained short-range operations. Communist China almost certainly will not have the capability to manufacture modern bombing aircraft within the next ten to fifteen years. Thus, the development of any significant C C A F capability for long-range air attacks will depend for many years on the receipt of suitable aircraft from the U S S R. Three. Assuming that the U S S R…
