Disadvantages include reduced range, payload and maneuverability compared to wireless drones, and the fiber-optic cord can get tangled or even broken off. These drones are very vulnerable to turbulent weather conditions owing to their lightweight build. This cable, which can extend up to several dozen kilometers, acts as both a control link and a live video feed pipeline. [Figure 2-3] Spoilers extend from the upper surface of the wings, alter the airflow, and cause the glider to descend more rapidly. Some high-performance gliders have dive brake speed limitations to prevent. In addition, although rarely, the optical fiber breaks, no matter how strong it is. It gets tangled, gets caught, that is, it has a number of physical limitations for operation. We are dealing. This paper explores the emergence of fiber-optic tethered drone technologies as a resilient alternative that significantly en-hances signal immunity, data security, and real-time control. The study outlines the technological evolution, military relevance, and design challenges associated with these. Fiber-optic gyroscopes (FOGs) have become one of the most important elements of modern inertial navigation systems due to their high accuracy, reliability, and independence from external signals such as satellite navigation.
