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

A guidance system where a missile receives mid-flight course corrections from an external source, such as ground control or satellite.

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.

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