"For years after World War II, both the United States and the Soviet Union had been trying to perfect a long-range missile capable of carrying nuclear warheads. Building on the successes of Nazi Germany in developing the V-1 and V-2 rockets that pummeled Great Britain during the last months of World War II, both American and Russian scientists raced to improve the range and accuracy of such missiles. (Both nations relied heavily on captured German scientists in their efforts.) In July 1957, the United States seemed to win the race when the Atlas, an ICBM with a speed of up to 20,000 miles an hour and an effective range of 5,000 miles, was ready for testing. The test, however, was a disaster. The missile rose only about 5,000 feet into the air, tumbled, and plunged to earth. Just a month later, the Soviets claimed success by announcing that their own ICBM had been tested, had “covered a huge distance in a brief time,” and “landed in the target area.” No details were given in the Russian announcement and some commentators in the United States doubted that the ICBM test had been as successful as claimed. Nevertheless, the Soviet possession of this “ultimate weapon,” coupled with recent successful test by the Russians of atomic and hydrogen bombs, raised concerns in America. If the Soviets did indeed perfect their ICBM, no part of the United States would be completely safe from possible atomic attack. Less than two months later, the Soviets sent the satellite Sputnik into space."
