in planning launch sites for intercontinental ballistics missiles
20 Gither tha US or the USSR, it is evident that the launch aites of
ora nation will be prime targets of the other in case of enen hostilities.
fee £ecilities of a launch aite may be "soft," that Le, spread owt on the
gupface of the earth; or they may be "hard," that 28, built underground
to minimize surface exposure and Vulnerability.
The vulnevability of
any launch site depends upon its degree of hardness and upon the enemy! 8
capability for hitting the selected target, which is usually expreseed
as circular probable error (CEP).
It is important to distinguish between the purely operational errors
(random) of the missile and the geodetic errors (systematic) which are
inherent in connecting the launch and target points on the earth's surfece.
The geodetic error’, as considered here, also includes the effects of
gravity anomalies upon the missile during flight and the certographic
aeror which arises when site positions are plotted on maps.
This report
is cencerned with geodetic errors onlyo
No attempt is mede to assess the
