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.
