It was earlier reported that the serial deliveries of the latest Sirius drones to the Russian troops would begin in 2023.
The Sirius (the Inokhodets-RU experimental design work) is a follow-up of the project of Orion drones. The Inokhodets-RU is outfitted with two engines, has an increased take-off weight, and can carry a bigger payload. The drone is expected to make its debut flight in May 2022.
The Sirius will be serial-produced at the first special production facility built by Kronshtadt in Dubna near Moscow for the manufacture of large-size unmanned aerial vehicles.
Sirius is a medium-altitude long-endurance (MALE) attack UAV, with a wingspan of 30m, length of 9m and height of 3.3m, a maximum combat load of 450kg, cruise speed of 295km/h, maximum altitude 12,000m, and an endurance of 40 hours.
