Post-Mortem on SNIE 11-6-57:
Soviet Gross Capabilities for Attack on the
Continental US in Mid-1960,
dated 15 January 1957
I. Findings
1. The predecessor of this estimate was NIE 11-56, completed
in March 1956. Since publication of the post-mortem of that estimate
(IAC-D-57/28, 20 March 1956), there has been considerable improve-
ment in intelligence on Soviet airfield development, and some additional
intelligence on inflight refueling and guided missile submarines. Some
gaps in intelligence on the performance characteristics of Soviet air-
craft have been narrowed (see IAC-D-57/Z8. 1, Revised, 4 December
1956). However, deficiencies continue to exist in intelligence on
these subjects, as well as on Soviet biological and chemical warfare
capabilities and Long-Range Aviation crew training and proficiency.
2. A number of other problems encountered in. preparing this
estimate, most notably the current and future strength of Soviet
Long-Range Aviation, were essentially the same as those met in
NIE 11-4-56, completed in August 1956. The general need for better
intelligence on Soviet military plans and programs, noted in the
post-mortem on NIE 11-4-56 (IAC-D-57/49, 20 September 1956),
continues to exist.
The IAC agencies and subcommittees are requested to take
appropriate action on the intelligence deficiencies and needs
described above.
