The Jupiter Missile was an early American ballistic missile developed in the 1950s. It was part of the United States' strategic arsenal during the Cold War and was designed to carry nuclear warheads. The missile had a range of about 1,500 miles and was primarily deployed in Europe as a deterrent against the Soviet Union. The Jupiter was a liquid-fueled missile, which made it more complex to launch compared to solid-fueled alternatives. It was eventually phased out in favor of more advanced systems, such as the Polaris and Minuteman missiles, reflecting the evolution of military technology during that era.
