a solicitation for details (RFI) seeking providers of unjammable drones, and if you’re curious about what “unjammable” entails, the aim is to identify alternatives “controlled via fiber optic cable” that are also “NDAA compliant.” In essence, they’re referring to wired drones. Unusual as it might sound, these varieties do exist. Wired drones cannot be jammed or interfered with from a distance — the sole means to disable them is to bring them down, which requires significant skill or specialized counteractions.
The cables linked to these drones can extend up to 20 kilometers (approximately 12 miles) or more, and they’re remarkably slender. Most limitations one might anticipate from a wired line are minimal. The primary issues are the risk of snagging, especially concerning battlefield remnants and nearby objects, or the drone’s own rotors. Decreased agility is also a disadvantage associated with wired drones compared to their wireless equivalents. The cable may restrict the drone’s operational radius; however, they frequently carry the cable spool onboard, utilizing a mount or housing to address this challenge. Because the cable spool is connected, it can decrease travel speed, additionally limiting space and capacity for extra loads like explosives or supplies.
Nevertheless, in spite of the tether, fiber-optic drones are difficult to detect, as the cable is extremely thin, and they provide a superior, more dependable signal — particularly in zones susceptible to wireless disruption. Moreover, as the FBI succinctly pointed out, they’re “unjammable.” The Moscow Times notes that fiber-optic drones are already operational on the battlefield. Ukraine and U.S. tech firms possess them too.
