11-B1 intercontinental ballistic missile

The 11-B1 is an intercontinental ballistic missile used by the UNSC Defense Force during the Human-Covenant War for long-range high-yield nuclear strikes against ground-based targets. They are capable of causing megatons of nuclear damage. It is housed in missile silos, reinforced against military strikes and normally staffed with a UNSCDF security detail.

The 11-B1 was considered obsolete prior to the Human-Covenant War, due to the relative stability within the UNSC. They were seen as unnecessary because of the resulting large-scale destruction, damaged ecosystem, nuclear fallout and radiation that follows the detonation of a 11-B1. However, during the war, 11-B1s were used as a last-resort weapon against Covenant forces that evaded planetary MAC defense weaponry.

Trivia
The Halo 3 multiplayer map Standoff is based around a cluster of 11-B1 missile silos. Additionally, several 11-B1 ICBMs can be seen flying overhead on the map, often two at a time.
