Intercontinental Ballistic Missiles (ICBM) are a class of rockets developed for the purpose of delivering warheads to targets almost anywhere on Earth. Use for discussing the rocket portion of the vehicle. Discussing warheads themselves are off-topic.
Intercontinental Ballistic Missiles, often known by their abbreviation ICBM, are a class of rockets developed during the Cold War for the purpose of delivering warheads (primarily nuclear) to nearly anywhere on Earth. ICBM creation during the Cold War also contributed to the development of rocketry for space exploration.
Questions should focus on the rocket portion of the vehicle. Discussions about the warheads and their use (beyond trajectories set by the rocket) are off-topic.
