...second generation of solid-fuel missiles, designed for mass production and mass deployment through the mid-1960s, must have smaller, higher-yield thermonuclear warheads to fit their smaller nose cones. The Navy's Polaris engineers managed to test their bird's initial warhead just before the moratorium, but could not test its higher-yield follow-up warhead; the Air Force's Minuteman (see SCIENCE) and the Army's Pershing are being developed at a cost of millions to fit warheads that have not been tested, and, under the moratorium, may not be. All these tests could...
...largest outlays of U.S. money abroad-more than $1 billion between that day and this, not counting extensive military equipment-Chiang's Formosa did survive, and one recent evening, the Gimo, accompanied by Madame Chiang, drove down to the heart of Taipeh to see the solid evidence of a decade of economic achievements at the First Annual Trade Fair of the Republic of China. "Hao, hao [good, good]," he said, as he passed through row after row of stalls proudly displaying Formosa-made trucks, machine tools, plastic toys-even Ivy League shirts...
...Rocket Society, a 90-ft. Titan missile stood outside the building; often discussed at the meeting were other liquid-fuel rockets. These types are dominant in the U.S. and probably in Russia. Their great advantage: they work. But also discussed at the meeting was the progress being made in solid-fuel rockets...
...solid-fuel rocket is like the monoplane in the early years of aviation. Biplanes were then the established type. They were easy to build because their double wings, braced by crisscrossed wire and struts, strengthened each other. But they were inefficient aerodynamically, and they had to be fooled with continually to keep their complex structure in proper order. The single wings of monoplanes were hard to make strong enough, but everyone knew that when they could be built, their efficiency and simplicity would make them dominant...
...solid-fuel rocket, too, is simple and vastly promising-but difficult. Chief problem is to get the fuel to burn dependably in such a way as to provide a precalculated, controllable thrust. In the liquid rocket this is done by an intricate system of gas generators, pumps, valves, turbines and tubing. But this advantage is also a source of trouble, because failure of one or more of these intricate parts is the usual reason for the frequent liquid-rocket misfires...
