Owl-13 drone. According to Russian media reports, the Simbirsk Design Bureau of Russia recently launched a reconnaissance drone - the "Owl-13". The drone adopts a modular design, which can quickly switch communication frequencies by replacing communication components, effectively avoiding enemy electronic interference. According to reports, the "Owl-13" drone can perform continuous reconnaissance missions for 1.5 hours, operating in both standard frequency bands and dedicated frequency bands to ensure control of the drone in complex electromagnetic environments. Most drones use a single communication frequency band, and changing the communication frequency band is very troublesome. The modular frequency conversion design of the "Owl-13" drone allows combat personnel to replace its communication components and set the required communication frequency band at any time, improving the aircraft's ability to respond to electronic interference. It is reported that the Russian military plans to replace the current reconnaissance drones with the "Owl-13". (New Society)
