The initial propulsion phase where a high-thrust motor accelerates the missile to operational velocity.

Fire-and-forget refers to a missile guidance system where the missile guides itself to its target after launch, requiring no further input from the operator.

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

A guidance method that uses inertial navigation sensors together with satellite‑based GPS signals to determine a missile’s position and steer it toward a target.

Launched from naval platforms, such as ships or submarines.

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