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.

ANNEX B
ESTIMATED REACTION AND RELOAD TIMES
Surface-to-Surface Missiles
We have no good evidence on the reaction
times of Soviet surface-to-surface missile
units. However, based on our analysis of the
characteristics of these systems and general
Soviet capabilities, we estimate the following
reaction times as of mid-1961:
a. SS-1: This 150 n.m. missile, which is
trar4orted in a fueled state by a track-lay-
ing vehicle, could be fired about five minutes
after reaching a presurveyed position.
b. SS-2 through SS-4: Although these sys-
tems are capable of varying degrees of mo-
bility Ave estimate that they would be deployed
to simple presurveyed sites when hostilities
become imminent. The reaction times for
units already deployed will vary with the
degree of alert and will be approximately the
same as discussed under SS-5 and 55-6
(ICBM) below. For units in transit at the
time of alert, 2-4 hours will be required to
launch the first missile after the unit has
arrived at the presurveyed or prepared site.
c. SS-5 and SS-6 (ICBM): We estimate the
SS-6, and probably the SS-5, will probably
utilize fixed sites. The Soviet design philos-
ophy, particularly in the respect to the fuel-
ing techniques employed at operational
launch sites, will critically affect ICBM re-
action times. Assuming that rapid reaction
time has been a Soviet objective, we estimate
the following minimum reaction times for
ready missiles under the three alert condi-
tions indicated:
Condition I: Crews on routine standby,
electrical equipment cold, missiles not
fueled. Reaction time 1-3 hours.
Condition II: Crews on alert, electrical
equipment warmed up, missiles not
fueled. Reaction time 15-30 minutes.
Condition III: Crews on alert, electrical
equipment warmed up, missiles fueled
and occasionally topped. This condi-
tion probably could not be maintained
for more than an hour or so. Reaction
time 5-10 minutes.
Air-to-Air and Air-to-Surface Missiles
The AAMs and ASMs have a short enough
reaction and reload time that they are not
the delaying factor in he takeoff of the air-
craft.
Surface-to-Air Missiles
All SAMs, including those mounted on
ships, will have a reaction time of no more
than a minute when alerted. The reload time
will vary with the type of missile system.
Naval Missile Systems lc
The reaction times in minutes for naval
systems are estimated as follows:
ROII- RELOAD
ALERT TINE TIME REMARKS
SS-N-1 1 5-10 5 DD Subsonic
cruise 30-40
n.m.
SS-N-2 1 5-10 5 DD Supersonic
cruise 30-40
n.m.
SS-N-4 10 15 No reload "Z" Class Sub
SS-N-5 5 15 No reload Advanced Sub
"Na estimates of reaction and reload times are
available for SS-N-3, a 300 n.m. supersonic cruise
missile designed to be fired from a surfaced sub-
marine.
