What is a disadvantage of navigated guidance?

Navigated guidance systems rely on continuous updates to adjust the trajectory of a projectile or missile towards a moving target. When the target is in motion, any changes in its position must be accounted for in real-time to ensure accuracy. Without these updates, the guidance system may become misaligned with the target’s path, leading to potential miss. This characteristic highlights a significant limitation of navigated guidance when dealing with dynamic targets compared to static ones, hence the chosen answer is valid.

In addressing the other options, while navigated guidance may introduce energy consumption considerations, the primary issue revolves around tracking moving targets and requires updates to maintain accuracy. Furthermore, the requirement for energy is context-dependent and not universally applicable. Regarding stationary targets, navigated guidance can indeed be employed; however, it may not be the most efficient method, making the highlighted answer more relevant. Finally, while homing guidance systems aim directly for their targets, navigated systems can still achieve a level of accuracy suitable for various applications, emphasizing that navigated guidance's primary limitation lies in adjusting to movement rather than inaccuracy itself.
