What defines a fire and forget weapon?

A fire and forget weapon is defined as a type of munition that is capable of seeking and engaging its target autonomously once it has been launched. This means that after the weapon is released, it does not require any further input or guidance from the operator; it is self-sufficient in seeking and locking onto its target. This capability allows operators to engage multiple targets or maneuver their platform immediately after launch without the burden of maintaining guidance.

In the context of the other choices, ongoing guidance after launch implies that the weapon cannot be classified as fire and forget since it contradicts the self-sufficiency aspect. A weapon that cannot hit moving targets suggests limitations in its targeting capability, which does not align with the characteristics of a fire and forget design, as many such systems are specifically engineered to track dynamic targets. Lastly, a weapon that can only be launched from a stationary position also does not fit the profile; fire and forget weapons can typically be launched from various platforms, including moving aircraft or vehicles. Therefore, the definition of a fire and forget weapon aligns perfectly with the identification of it being entirely self-sufficient after launch.
