What is meant by Circular Error Probable?

Circular Error Probable (CEP) is a statistical measure used to evaluate the accuracy of a weapon system, particularly in military contexts. It defined as the radius of a circle, centered on the target, within which 50% of the weapon's impacts are expected to fall. This metric specifically highlights the expected dispersion around the target, providing a clear representation of the accuracy of the delivery system.

In essence, when a weapon system boasts a smaller CEP, it indicates that the system is capable of delivering munitions more accurately towards the intended target, thus enhancing the effectiveness and efficiency of military operations. Understanding CEP is crucial for evaluating not just the performance of individual weapon systems but also for strategic planning and mission success criteria.
