To casual kibitzers at Cape Canaveral, the Polaris missile that took off from a dry-land pad and soared successfully downrange may have represented simply one more test shot. To U.S. Navy technicians, the deadly bird signaled the start of a new era in U.S. rocketry. A revolutionary new control...
Standard weapon of U.S. nuclear submarines, the Polaris burns solid fuel, and it cannot be steered, as liquid-fuel rockets are, by swiveling the whole combustion chamber. Instead, Polarises now at sea use jetavators-movable nozzles inserted in their jet streams to deflect them and thus keep the rocket on course. No one likes jetavators; they are inherently troublesome, and their drag on the fast-moving jet stream soaks up precious thrust power even when they...
The new Polaris is equipped with nozzles that have no obstructions and no moving parts. For directional control, a small amount of freon gas is shot into the side of the hot exhaust stream, deflecting it just as if the nozzle had been turned. The system is light, and since...
Lerner, who has just returned from seven years of studying problems of unity in Europe, said that only default on United States' undertaking in Berlin would be likely to prompt a major reevaluation in the immediate future. But as strategic weapons systems comparable to Minuteman and Polaris make nuclear deterrence...
