📖 TERMS ON THIS PAGE10terms
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.
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.
Propellant consisting of a solid mixture of fuel and oxidizer, enabling long-term storage and immediate launch readiness.
Designation for intercontinental ballistic missiles (ICBMs) deployed and launched from submerged submarines.
Relating to nuclear weapons that derive destructive power from both fission and fusion reactions, typically used in intercontinental ballistic missiles.
