...world that was surprised as much as it was dismayed (see THE WORLD). Nikita Khrushchev announced that the Soviet Union would resume test ing its nuclear weapons, boasted of a superbomb that had the force of 100 million tons of TNT-5,000 times the size of the A-bomb that leveled Hiroshima, and five times the size of the biggest bomb in the U.S. arsenal. Two days later, the testing began with a medium-sized bomb explosion in Central Asia. Thus ended a three-year moratorium on nuclear testing by the U.S. and the U.S.S.R...
Open Question. To exploit the U.S.'s propaganda advantage. Kennedy decided to make no mention of his plans to resume tests until some time after the Russians exploded their first bomb, an event he expected momentarily. In the meantime. Russia would stand revealed to the world as the atomic aggressor. Thus, Kennedy's first public statement, issued Wednesday night at 9:50, declared that the Soviet Union's decision "presents a threat to the entire world by increasing the dangers of a thermonuclear holocaust.'' But the statement left Kennedy's own plans purposefully vague...
What U.S. weapons have already been tested? At the start of the test moratorium in the fall of 1958, the U.S. had a family of well-tested bombs ranging in power from less than one kiloton (1,000 tons of TNT) up to 20 megatons (equivalent to 20 million tons of TNT). The 20-megaton weapons are too heavy for existing U.S. missiles, but more than one of them can be carried by far-ranging B-52 bombers. U.S. authorities, both civilian and military, see little advantage in more powerful bombs, such as the 100-megaton horror mentioned by Khrushchev...
...missile could be rigged to deliver a bigger bang; a decrease in weight of the current-strength warhead would allow an increase in the missile's range. The same effect would show up all along the line; a B-52 could carry twice as many improved 20-megaton bombs. The U.S. has many new weapons systems with nuclear warheads that have yet to be explosively tested. No ICBM, for instance, has carried a nuclear warhead out of the atmosphere and back again and demonstrated that after its high ride the warhead will still explode. No antimissile nuclear weapon...
Biggest activity in the shelter business" has been in California-a phenomenon apparently due in equal measure to the state's unusual concentration of bomb-conscious scientists and to its even greater concentration of those who, whatever is being done, want to be the first to do it. Fox Hole Shelter, Inc., offshoot of a swimming-pool firm that got into shelters two years ago by turning its original product upside down, has already sold 236 Fox Holes from San Luis Obispo to San Diego. Sacramento's Atlas Bomb Shelter is starting to merchandise a 35-ton prefab...
