This is National Intelligence Estimate 11-5-61, Soviet Technical Capabilities in Guided Missiles and Space Vehicles. It was submitted by the Director of Central Intelligence and concurred in by the United States Intelligence Board on 25 April 1961. The estimate assesses Soviet surface-to-air, antimissile, air-to-air, air-to-surface, ballistic, ICBM, naval and space programs. It concludes that the first Soviet ICBM unit was probably operational around 1 January 1960. It also says there is no evidence the Soviets are developing offensive space weapons. It contains no UFO material.

earth satellites suitable for supporting
manned orbital flights; and, most re-
cently, the successful orbiting and recov-
ery of a man. (Para. 150)
26. The reliability achieved in Soviet
space shots has been much lower than
that of the Soviet ICBM. The Soviets
have achieved 14 successful launchings of
space vehicles, but we believe that there
have been nearly as many launchings
which resulted in failures. Moreover, sev-
eral of the vehicles which were success-
fully launched apparently did not func-
tion as planned. Most space failures
were apparently caused by factors unique
to the space program, such as the addi-
tion of upper stages to the basic booster
and in some cases the requirement to
launch at stipulated times. (Para. 152)
27. To date the USSR has apparently not
launched any space vehicles specifically
for military purposes. However, many of
their space experiments have provided in-
formation which would be useful in the
development of future military space sys-
tems. It would be technically feasible at
present for the Soviets to equip earth
satellites for such military support roles
as communications, reconnaissance, nav-
igation, or collection of weather data. We
estimate that such systems could appear
at any time. There is no evidence that
the Soviets are developing offensive space
weapons. However, the Soviets have un-
doubtedly undertaken research and stud-
ies in this,area. Soviet success in space
as exemplified by the Venus probe, the
most recent successful orbiting and re-
covery of a man, and the capability to
orbit still heavier payloads over the next
few years, leads to the conclusion that
the Soviets are technically capable of
achieving an orbital bombardment ve-
hicle toward the end of the period of this
estimate. Moreover, the Soviet leaders
might seek to derive some psychological
or political advantage by hinting or even
boasting that the USSR had a significant
capability in such weapons. The launch-
ing of vehicles for which the Soviets
claimed a military capability or other So-
viet achievements in space could lend
credence to such claims. (Paras. 149,
175)
28. We believe that the Soviets will con-
tinue to capitalize on their possession of
very powerful propulsion systems. The
USSR could now place in orbit a 20,000
pound satellite, and this orbital payload
could be increased to about 25,000 pounds
in about 1962. An instrumented lunar -
soft landing probably can be made this
year, and additional deep space probes
probably will be attempted during the
next year or so. Finally, there is evi-
dence that the Soviets are now developing
a liquid rocket engine with a thrust of
some one to two and a half million pounds
which could be available in about 1963.
Such engines could be used in clusters in
the 1965-1970 time period to launch earth
satellites of 50 to 100 tons. (Paras. 167-
174)
