The U.S. is caught flat-footed when the Soviet Union launches Sputnik in October 1957. The U.S. missile program is years behind. The U.S., however, had launched the first atomic-powered submarine, the Nautilus (SSN-571), in 1956 and raced to develop the capability to launch missiles while submerged by 1960.
