What is the primary component of a guided munition?

The primary component of a guided munition is the guidance system, which is essential for ensuring the munition can accurately hit its intended target. This system utilizes various technologies such as GPS, inertial navigation, or laser guidance to steer the munition during flight. The effectiveness of a guided munition largely relies on its ability to adjust its trajectory based on the guidance provided, distinguishing it from unguided munitions that follow a predetermined parabolic path after being launched.

While the explosive charge is critical for the munition's destructive capability, the propellant is necessary for launching the munition, and the fuze mechanism is crucial for detonation upon impact. However, without a sophisticated guidance system, the munition would lack precision, rendering its use less effective in modern combat scenarios where accuracy is key. Therefore, the guidance system is paramount in defining a munition as "guided."
