Guidance system combining inertial navigation (self-contained motion tracking) with GPS (satellite-based positioning) for precise trajectory correction in ballistic missiles.

MIRV (Multiple Independently targetable Reentry Vehicle) is a ballistic missile payload that carries several warheads, each capable of being aimed at separate targets after reentry.

Relating to or using nuclear energy, typically fission, for propulsion or power generation in military vessels.

Countermeasures deployed by ballistic missiles to evade interception, including decoys, chaff, or other systems to confuse missile defense radars.

Capable of being transported and launched from rail platforms.

Silo-based: a launch configuration in which an intercontinental ballistic missile is stored and launched from a hardened underground silo.

Propellant consisting of a solid mixture of fuel and oxidizer, enabling long-term storage and immediate launch readiness.

Relating to nuclear weapons that derive destructive power from both fission and fusion reactions, typically used in intercontinental ballistic missiles.
