SWITZERLAND 
Another nation which has been actively engaged in missile pro- 
duction is Switzerland. The Orelikon Co. has developed missiles in 
all but one of the four major military categories. 
The surface-to-air (antiaircraft) development of the “Series 50” 
missiles started shortly after World War II. They weigh about 550 
pounds each and have a range and ceiling of 12 miles. The more 
recent “Series 54” has a takeoff gross weight of 772 pounds. It is 
powered by a nitric acid-hydrocarbon fuel, liquid rocket engine de- 
livering about 2,200 pounds thrust. The range and ceiling are 15.5 
miles and 9.8 miles respectively. The “Series 56” and “Series 57” 
are the latest versions under development. 
In the air-to-surface category, Orelikon has produced two outstand- 
ing FF, FF (forward-firing, folding-fin) missiles. These two missiles 
have been developed expressly for the British Gloster Meteor and 
Venom aircraft. The Cobra, another Orelikon missile, is a surface- 
to-surface, wire-controlled, solid-propellant, antitank missile. The 
weight of the Cobra is reported to be one-tenth the weight of the 
U.S. Army’s Dart. 
The most significant aspect of the Orelikon Co.’s operation is its 
policy of selling missiles to any foreign power throughout the world. 
SWEDEN 
Sweden, another small nation engaged in missile activities, has one 
of the better rounded programs. In addition to her missile activity, 
she is actively engaged in research on high-energy fuels, ramjet pro- 
pulsion, and advanced rocket designs. Specifically, Sweden’s missile 
program has one missile in three of the four basic military categories. 
These include the Jaktrobot, an air-to-air, in development; the 
Sjorobot, a surface-to-surface naval missile soon to become oper- 
ational ; and the Luftforsvarsrobot, a surface-to-air missile in develop- 
ment for her Air Force since 1955. This missile is said to be capable 
of interception at very high altitudes and at extreme ranges (120 to 
150 miles). 
UNITED STATES 
The United States missile program after World War II was one 
which emphasized the “broad look” into the state-of-the-art and not 
quantity production of systems with questionable tactical value, 
whereas the Soviets adopted postwar crash programs which utilized 
German rocketry knowledge both for immediate production and as 
a point of departure for building systems that could span continents. 
It was intended that the policy of the United States should eventu-
