Guidance

Ordnance can be divided into guided and unguided categories based on their targeting capabilities. Guided ordnance, such as
Precision-guided munitions A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a type of weapon system that integrates advanced guidance and control systems, such as Global Positioning System, GPS, laser guidance, or Infrared ...

tracking to precisely hit designated targets. Unguided ordnance, commonly known as "dumb bombs," lack guidance systems and rely on the aircraft’s release parameters to strike a target. Though less accurate, unguided bombs are often used for area strikes and are more cost-effective.
