Intercontinental ballistic missile

An intercontinental ballistic missile (often abbreviated ICBM) is long range ballistic missile typically equipped to deliver a nuclear payload, usually in the form of one or more nuclear warheads.

Background
An ICBM has a range that typically exceeds 5500 kilometers (3417.5 miles). The missile launches up into low orbit, where it can then deploy one or more nuclear warheads on almost any location on the planet. They could be fitted with a variety of payloads, ranging from high explosive to biowarfare loadouts, but the most used were nuclear warheads. A typical ICBM has a blast radius of several miles and a fallout range of even further.

ICBM silos can be found throughout the Capital Wasteland. A (non-functional) ICBM launch terminal, launch codes, and facility for a Minuteman XI missile can be found at Fort Constantine. Silos can also be found at Fort Bannister and Wheaton Armory. Las Vegas was spared from Chinese ICBMs during the Great War by anti-missile defense systems developed by Robert House. The missiles in Hopeville and Ashton never left their silos.

In Appalachia, several silos with active ICBMs are still operational and usable to create irradiated blast radiuses anywhere on in Appalachia, but are primarily meant as the last resort to dealing with the Scorchbeast queen and ending the Scorched Plague.
