In 1958, the first American ICBM successfully flew and launched the Atlas rocket family
The successful 1958 flight of the SM-65 Atlas marked the birth of America's first operational intercontinental ballistic missile, a technological marvel that eventually carried the first Americans into orbit.
On November 28, 1958, the United States achieved a massive Cold War milestone when the SM-65 Atlas completed its first full-range flight. As the nation's first functional ICBM, it was designed to deliver nuclear warheads across oceans, fundamentally changing global geopolitics and the concept of strategic deterrence.
