Designation for an ICBM equipped with a canister launcher, enabling rapid deployment and reduced exposure during launch.

A missile launch method where the missile is ejected from its launch tube by gas pressure before the rocket motor ignites, typically used in submarine-launched ballistic missiles.

A depressed-trajectory refers to a suborbital ICBM flight path with a lower than normal apogee, reducing warning times and allowing for a surprise attack.

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

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

Road-mobile: a deployment mode for ICBMs where the missile is mounted on a wheeled or tracked transporter‑erector‑launcher that can travel on public roads, enabling movement and concealment.

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.
