The Aeroprakt A-22 “Foxbat,” originally designed as a light recreational aircraft, has recently drawn attention after being modified by Ukrainian forces into a long-range UCAV (Unmanned Combat Aerial Vehicle).
This transformation illustrates a shift in asymmetric warfare, where civilian technologies are repurposed for military use, thereby creating new, unconventional offensive capabilities.
On April 4, 2024, Russian media reported that two Aeroprakt A-22 Foxbat UCAVs (Unmanned Combat Aerial Vehicles), modified by Ukrainian forces, were used to carry out strikes in the Republic of Tatarstan, over 1,200 kilometers from the Ukrainian border. These UCAVs reportedly targeted a Shahed-136 drone manufacturing facility and an oil refinery, marking the first use of this strategy and this type of aircraft in that region since the start of the conflict.
The Aeroprakt A-22 Foxbat, known for its versatility and simplicity, was designed by Ukrainian engineer Yuri Yakovlev as a two-seater ultralight aircraft. First flown in 1996 and introduced in 1999, the A-22 remains popular in recreational aviation due to its lightweight design, ease of assembly, and maneuverability. With its high-wing design, tricycle landing gear, and a stall speed of 52 km/h, the A-22 is manageable and accessible to amateur pilots. Its structure, combining metal and composite materials, offers a balance between durability and lightness, supporting its use in diverse environments.
Typically powered by an 80 to 100 horsepower engine, the A-22 reaches a cruising speed of 160 km/h and a maximum speed of 170 km/h, with a flight range of approximately 1,100 km. Although designed for civilian use, the construction and versatility of the A-22 have made it an appealing candidate for conversion into a UCAV platform, allowing its use in combat operations.
To transform the A-22 into a UCAV capable of long-range missions, significant modifications were necessary. Removing non-essential components, such as seats, interior panels, and manual control systems, was likely one of the initial steps, reducing weight and freeing up space for additional fuel and payload capacities. This restructuring also required reinforcing certain structural parts to withstand the stresses associated with increased load, including the fuselage and wings.
One critical adjustment for the A-22’s new role was extending its operational range. Although the original aircraft had a maximum range of approximately 1,100 km, Ukrainian forces reportedly modified it to fly over 1,200 km to reach targets deep within Russian territory, such as the Republic of Tatarstan. Achieving this required increasing fuel capacity, likely through additional tanks installed in vacated spaces, maximizing the A-22’s endurance without significantly impacting weight distribution or aerodynamic performance.
To complement the increased fuel capacity, optimizing the propulsion system was also essential. This might involve fine-tuning the existing Rotax engine or replacing it with a more fuel-efficient variant to support long-duration missions.

With the conversion of the A-22 into an unmanned aircraft, its control systems required substantial upgrades. A sophisticated control and navigation system capable of remote management was integrated, allowing for long-range autonomous flight. Precision guidance was achieved through GPS and inertial navigation systems, providing accurate trajectory toward designated targets even in electronic warfare conditions.
Redundant navigation systems, critical in high-risk environments, ensure operational reliability, allowing the UCAV to readjust its course if primary systems are disrupted. Long-range communication systems, potentially encrypted for security, would maintain the link with command centers, permitting real-time updates and adjustments during flight. These adaptations enable the A-22 to execute precise missions deep within enemy territory.
For its UCAV role, the A-22 was reconfigured to carry an explosive payload, necessitating the engineering of a dedicated compartment to ensure safe transport and effective deployment. This compartment would need to support up to 90 kg of explosives, potentially tailored for the desired impact and damage profile. A reliable detonation mechanism—likely triggered on impact or remotely activated by operators—was essential for mission success.
This configuration makes the A-22 capable of targeting specific installations, such as infrastructure or production facilities, with high-impact munitions, thereby expanding Ukraine’s strategic options in the ongoing conflict.
The modification of the A-22 into a UCAV introduces a new strategic capability for Ukrainian forces, allowing long-range strikes against critical infrastructure and military production sites. The attack on a Shahed-136 drone factory and an oil refinery over 1,200 km from the Ukrainian border illustrates how this capability disrupts the perceived safety of rear-echelon sites. By targeting production and resource facilities deep within Russia, the A-22 UCAV exerts a psychological impact on the enemy and imposes a logistical burden by requiring increased defensive measures over a larger area.
The accessibility and relatively low cost of kit-built aircraft like the A-22 Foxbat also highlight the potential for similar modifications across other platforms. This tactic could inspire other nations or non-state actors to adopt similar approaches, raising the stakes in asymmetric warfare. The civilian origins and simplicity of the A-22 allow for rapid adaptation, making it an effective platform for such missions with minimal detection risk, especially when flying at low altitudes to evade radar systems.
While the conversion of the A-22 demonstrates adaptability, it carries inherent risks and challenges. The transformation process requires a coordinated approach involving specialists in engineering, avionics, and explosives, which can strain resources and extend timelines. Furthermore, maintaining operational security is crucial; any exposure during the testing phases could lead to countermeasures that diminish the UCAV’s effectiveness in combat.
Additionally, executing missions over such distances presents operational risks. Long-range control can be compromised if communication links are disrupted, potentially leading to mission failure or unintended target engagement. Encryption and redundancy are thus essential, but even with these measures, adversarial electronic warfare remains a persistent threat.
