Intercontinental ballistic missile

An intercontinental ballistic missile or ICBM is a long-range ballistic missile typically with a range exceeding 5,500 kilometers, typically designed for the delivery of nuclear weapons. The United Nations Space Command maintains at least one ICBM base equipped with 11-B1 Intercontinental Ballistic Missiles in Africa on Earth.

Historically, ICBMs have been able to be launched from land-based missile silos, mobile missile trucks, or sea-based ballistic submarines. Stationary bases allow easy maintenance and refueling, as well as protecting from military attack and possibly from a nuclear first strike. Submarine or truck-launched missiles have the advantage of quick mobility and, in the formers case, stealth, making them difficult for enemy forces to detect and counter quickly enough.
