The Sokol Altius is a Russian medium-altitude, long-endurance (MALE) unmanned combat aerial vehicle (UCAV) designed for reconnaissance, strike, and electronic warfare missions.
The Sokol Altius is a Russian-developed medium-altitude, long-endurance unmanned combat aerial vehicle. Initiated in 2011, the program has produced several prototypes, culminating in the Altius-RU variant. The drone features a high-mounted wing with a V-tail configuration and extensively utilizes composite materials to reduce weight and enhance performance. It is powered by two VK-800C turboprop engines, enabling extended flight durations suitable for reconnaissance, strike, and electronic warfare missions. The Altius is equipped with advanced avionics and a satellite communication system, significantly extending its operational range. Comparable to Western counterparts like the MQ-9 Reaper, the Altius represents a significant advancement in Russian unmanned aerial capabilities.
History of the Development of the Sokol Altius
In the early 2010s, recognizing the increasing importance of unmanned systems in modern warfare, the Russian Ministry of Defence initiated a program to develop a domestically produced medium-altitude, long-endurance UAV. The objective was to reduce reliance on foreign technology and to create a platform capable of performing a range of missions, from reconnaissance to combat operations.
In October 2011, the Ministry awarded a contract worth 3 billion rubles to OKB Sokol, based in Kazan, to develop this new UAV. The project aimed to produce a drone comparable to the U.S. MQ-9 Reaper, with capabilities suitable for both the Russian Aerospace Forces and the Navy.
The first prototype, named Altair, was unveiled in 2014 and conducted its maiden flight in 2016. This initial demonstrator laid the groundwork for subsequent iterations. Following Altair, the Altius-M prototype emerged, featuring design refinements and enhanced capabilities. The development process faced several challenges, including technical setbacks and financial constraints. Notably, the loss of access to French engines necessitated the development of indigenous powerplants, leading to delays.
In April 2018, the program encountered a significant hurdle when Alexander Gomzin, the Director General of OKB Sokol, was arrested on charges of embezzling 900 million rubles allocated for the Altius project. This incident prompted the Ministry of Defence to transfer the project to the Ural Civil Aviation Plant in Yekaterinburg later that year.
Under new management, the program progressed, and the Altius-U prototype made its first flight in 2019. This variant introduced a satellite communication system, significantly extending its operational range and enhancing its mission capabilities.
The final iteration, known as Altius-RU (Reconnaissance and Combat), represents the culmination of the development process. This version is tailored for both reconnaissance and strike missions and is considered the production model for the Russian military. In February 2021, a state contract was signed between the manufacturer and the Ministry of Defence for the supply of the first batch of Altius drones, with deliveries expected to commence within the year.
Throughout its development, the Altius program has faced numerous obstacles, including technical challenges, management issues, and legal troubles. Despite these setbacks, the project has persevered, resulting in a platform that enhances Russia’s unmanned aerial capabilities. The Altius is poised to become a cornerstone of Russia’s heavy drone fleet, providing a versatile tool for modern warfare.
Design of the Sokol Altius
The Sokol Altius exhibits a design that balances aerodynamic efficiency with operational functionality. Its airframe is constructed with a high-mounted wing and a V-tail configuration, a design choice that enhances stability and control during flight. The extensive use of composite materials in the construction reduces the overall weight, contributing to improved endurance and performance.
The drone is powered by two VK-800C turboprop engines, developed by the Klimov Design Bureau. These engines are mounted on pylons beneath the wings, each driving a three-bladed propeller in a tractor configuration. The VK-800C engines were selected to replace the originally intended foreign engines, aligning with the program’s goal of technological self-reliance.
The Altius is equipped with a satellite communication system, enabling beyond-line-of-sight control and data transmission. This capability allows operators to manage the drone over extended distances, significantly enhancing its operational range and flexibility.
The payload bay is designed to accommodate various mission-specific equipment, including electro-optical/infrared sensors, synthetic aperture radar, and electronic warfare systems. This modularity allows the Altius to be configured for a range of missions, from intelligence gathering to electronic attack.
The landing gear is retractable, reducing aerodynamic drag during flight and contributing to the drone’s endurance. The undercarriage is designed to support operations from semi-prepared runways, providing flexibility in deployment.
The design of the Altius reflects a focus on versatility and adaptability, enabling it to perform a wide range of missions in various operational environments. Its combination of advanced avionics, modular payload capacity, and extended range positions it as a significant asset in modern aerial warfare.
