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.

Launched from a ground-based platform, such as a vehicle or tripod, rather than an aircraft or other airborne system.

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

Sea‑skimming is a low‑altitude flight profile in which a missile or projectile flies close to the sea surface to minimize radar detection and increase survivability.

A two-stage ATGM propulsion system where a booster stage initially accelerates the missile before a sustainer stage maintains flight velocity.
