What is a cruise missile?

A cruise missile is defined as a small, pilotless aircraft designed to deliver a payload, typically with precision targeting, by flying at a relatively low altitude and maintaining a consistent velocity towards its target. The distinguishing characteristic of a cruise missile is that its engine runs continuously throughout its flight path until it reaches its target, allowing for sustained propulsion and maneuvering capabilities. This makes it different from other types of munitions, which may not be powered for the entirety of their descent or trajectory.

The option describing the cruise missile correctly captures these key features, highlighting its autonomous nature and the operational behavior of its engine. Its ability to accurately strike targets from a distance, often with smart technology or guidance systems, further emphasizes its role in modern warfare.

In contrast, the other options do not accurately represent the characteristics of a cruise missile. For instance, unguided weapons are not reliant on continuous powered flight and typically lack precision. Conventional explosives dropped from aircraft do not have independent flight capabilities like a cruise missile and are instead dependent on gravity for deployment. Similarly, a guided bomb with a parachute, while designed for precision, does not maintain powered flight like a cruise missile does.
