25 km above the ground and 40 days without landing: The revolutionary “Argus” UAV was unveiled in St. Petersburg
At the St. Petersburg International Forum, held in early June 2026, a unique Russian-developed unmanned aerial vehicle was unveiled. The new product was displayed at the PSB company’s booth. The “Argus” drone, developed by Stratolink, is a new-generation atmospheric satellite capable of performing tasks at altitudes inaccessible to most existing drones.
Purpose and Features
The “Argus” UAV has a wide range of applications. The aircraft’s primary purpose is to relay communications, which is critical for ensuring reliable communication across large areas. In addition, the drone is designed to perform aerial photography and remote sensing missions, making it a valuable tool for environmental monitoring, mapping, and infrastructure surveillance.
The ability to use “Argus” as a long-range radar detection system deserves special attention. Its capacity to remain airborne for extended periods at high altitudes allows the aircraft to effectively perform early warning and airspace surveillance functions.
Technical Specifications
The «Argus» unmanned aerial vehicle has the following tactical and technical characteristics:
- Maximum flight altitude: up to 25 km
- Flight duration: up to 40 days
- Wingspan: 40 meters
- Weight of the unit: 315 kg
- Payload: up to 40 kg
- Looping speed: 120–140 km/h
Innovative Technological Solutions
To achieve the specified performance characteristics, the developers implemented a number of cutting-edge technological solutions. The aircraft’s airframe is 90% composite, providing an optimal strength-to-weight ratio. Highly efficient flexible solar panels are mounted on the wing, providing a long-term power supply for the drone’s systems.
The design features coaxial variable-pitch propellers and redundant ailerons with a «hover» function, which enhances the aircraft’s maneuverability and stability. An important feature is the ability to generate energy while gliding, which further extends flight duration.
The use of artificial intelligence with algorithms for detecting updrafts deserves special attention. This system allows the drone to automatically locate and utilize thermal currents to conserve energy and extend its flight time.
Significance for the domestic industry
The presentation of the “Argus” UAV at the St. Petersburg International Forum demonstrates the high level of development of Russian technology in the field of unmanned aviation. The aircraft, capable of operating at stratospheric altitudes for a month and a half, opens up new possibilities for both civilian and specialized applications. The successful implementation of the “Stratolink” project strengthens Russia’s position in the development of advanced unmanned systems.
