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.

13. Simplicity and ruggedness have been
major criteria in Soviet development of
ballistic missile systems from the short
range to the ICBM classes. All systems
probably employ radio-inertial guidance,
achieving operational accuracies of about
one-half to two n.m. depending on the
range of the system. All use nonstorable
liquid propellants except the 150 n.m.
missile which uses storable liquid propel-
lants. Short and medium range Soviet
missiles are designed for road mobility
and rail transportability. The ICBM, and
probably the IRBM, are designed to be
launched from fixed positions, and would
be heavily dependent on the Soviet rail
net. Medium range, IRBM, and ICBM
systems are suitable primarily for the de-
livery of nuclear payloads, but short range
systems may be designed to employ nu-
clear, HE, or CW warheads, depending on
tactical considerations. (Paras. 84-94)
14. Our evidence on Soviet production
and deployment of these missile systems
is far from satisfactory. We have infor-
mation pointing to several plants which
may be engaged in production of ballistic
missiles, but it is insufficient to establish
production rates for any class of missile.
Test range activities indicate the training
of troop units to employ short and me-
dium range systems, as well as continued
research a'rid development to improve the
performance of the systems themselves.
Our best evidence on deployment relates
to medium range missiles: some 700 n.m.
missiles are probably now deployed in
East Germany; 700 or 1,100 n.m. missiles
are probably also deployed in the several
areas near Soviet borders in the Baltic,
Carpathian, and Far Eastern regions.
(Paras. 88, 90, 92)
15. Our evidence on future Soviet ballistic
missiles is likewise fragmentary and in-
conclusive. We believe that the Soviets
will strive to improve the accuracy, re-
liability, ease of handling, mobility, and
reaction times of all classes of missiles.
Among other things, this effort probably
will lead eventually to solid or storable
liquid propellants and to all inertial guid-
ance. (Para. 95)
ICBM Program
16. We have relatively firm evidence on
the Soviet ICBM test range and the test-
firing program from which we have been
able to derive basic characteristics of the
ICBM system and—though with some
probable margin of error—basic factors
affecting its performance under opera-
tional conditions. In the 31/2 year period
since the first successful flight test in Au-
gust 1957, the Soviets have launched
about 35 generally successful ICBMs on
the test range. Considering the observ-
able patterns in test firing in relation to
other Soviet missile programs and to the
space program which has shared ICBM
boosters, facilities, and experience, we
conclude that the USSR has been con-
ducting a careful and generally successful
ICBM development program, at a deliber-
ate pace rather than on a "crash" basis.
(Pares. 98, 102-105)
17. The sum of our information is incon-
clusive as to the precise timing of initial
Soviet ICBM deployment. However, we
consider that the satisfactory develop-
ment of a 5,000 n.m. ICBM by the end of
1959, the probable manufacture of pro-
duction missiles beginning early in that
