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.

A UCAV (Unmanned Combat Aerial Vehicle) is an unmanned combat aircraft designed for offensive military operations without a pilot on board. Used for missions like armed reconnaissance, precision strikes, and ground support, UCAVs are equipped with weapons systems, such as missiles and bombs, allowing for autonomous or remote-controlled strikes. There are several UCAV variants tailored to specific missions. Armed reconnaissance UCAVs are commonly used to locate and engage targets in real time on the battlefield. Strategic UCAVs are larger, with extended range and endurance, allowing for deep strikes within enemy territory. Close air support UCAVs operate at lower altitudes to directly support ground troops. Lastly, kamikaze drones, or loitering munitions, are a specific type of UCAV designed for a one-time attack, where the drone itself acts as the munition, detonating on impact with its target. These variants allow military forces to adapt to various combat conditions and environments, making UCAVs indispensable in modern warfare.

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.

The conversion of the A-22 Foxbat into a long-range UCAV exemplifies the innovative use of civilian technology for military purposes. This trend may continue as conflicts evolve, with similar modifications applied to various civilian platforms to expand strategic options. However, the success of such conversions will likely depend on the adaptability of base platforms, the availability of modular avionics, and the expertise of modification teams.

For nations or organizations without access to sophisticated military technology, modifying civilian platforms into UCAVs could become a cornerstone of modern warfare, enabling cost-effective, high-impact attacks. Given the success of the A-22, similar strategies may soon be adopted by other actors, increasing the diversity and unpredictability of airborne threats in contemporary conflicts.

The conversion of the Aeroprakt A-22 Foxbat into a long-range UCAV exemplifies the innovative use of a civilian aircraft in combat scenarios, particularly in asymmetric warfare. By equipping the A-22 with enhanced navigation, fuel, and payload capacities, Ukrainian forces have developed a new method for strategic strikes deep within enemy territory, precisely targeting critical infrastructure. This development not only illustrates Ukraine's adaptability in a resource-constrained environment but also signals a shift in warfare, where civilian technologies are militarized to overcome traditional military resource limitations.

The success of the A-22 Foxbat in this role could lead to broader applications of similar tactics, inspiring the integration of kit-built or commercially available aircraft into military arsenals worldwide. As technology and warfare continue to intersect, such innovations may reshape the landscape of modern conflict, compelling both state and non-state actors to reassess their defensive and offensive strategies in response to the growing threat of modified civilian UCAVs.


Ukraine’s New Factory-Smashing Drone Is A $90,000 Sport Plane With A Robot At The Controls

To pull off one of its deepest strikes ever targeting Russia’s strategic industries, the Ukrainian government took a locally-made ultralight sport plane, swapped its manned controls for robotic controls and packed it with explosives.

Video of the emergency response following the Tuesday attack on the Alabuga Special Economic Zone industrial campus, 600 miles from the Ukrainian border, reveals that the drone—possibly two of which struck the campus—is based on an Aeroprakt A-22. A high-wing, single-propeller sport plane with room for two.

That the Ukrainians could convert an A-22 into an explosive drone strongly implies the strike on the Alabuga facility, which reportedly assembles Iranian-designed Shahed drones for Russia’s own war effort, won’t be the last for this new drone type.

The simple, reliable and innocuous A-22 after all lends itself to drone conversion. And equally importantly, it’s made in Ukraine—and it’s affordable at just $90,000 a copy.

To put that into perspective: an A-22-based drone, capable of traveling 600 miles through Russian air defenses to deliver—with high accuracy—potentially hundreds of pounds of explosives, costs just slightly more than a single American-made Javelin anti-tank missile costs. Ukrainian troops fire Javelins by the hundred.

An A-22 drone is, on a production level, scalable. Thus, “we expect that more attacks will be attempted in the future,” the Ukrainian Conflict Intelligence Team stated after analyzing the Alabuga raid, which reportedly injured 14 people and damaged either the drone factory or a nearby dormitory for workers.

The A-22 is the kind of plane a middle-class hobby pilot might buy for fun jaunts over the local airport. “If you're looking for a rugged aircraft that's easy to handle, has amazing short field performance, yet is capable of cruising at 95-plus knots, while (legally) carrying a good load—you've come to the right place!” Arizona-based Leighnor Aircraft, which deals the A-22 in the United States, boasted on its website.

“Control and safety,” Leighnor stressed. “Stalling is a non-event, even without flaps. ... At slow speeds, the controls are light and effective—[and] at higher speeds they firm-up and make cruising a more relaxed affair.”

“Correctly proofed, metal structures are durable and resistant to the external environment,” the company added. “The best news yet, it all starts for less than $90,000!”

We don’t know exactly how the Ukrainians transformed the A-22 into a killer drone, but it’s not hard to guess. Remember that, in 2019, the U.S. Air Force stripped the seats and controls out of a 1968-vintage Cessna 206 light plane and installed, in their place, a set of computer-driven servos.

“The system ‘grabs’ the yoke, pushes on the rudders and brakes, controls the throttle, flips the appropriate switches and reads the dashboard gauges the same way a pilot does,” the Air Force Research Laboratories explained. “At the same time, the system uses sensors, like GPS and an inertial measurement unit, for situational awareness and information-gathering. A computer analyzes these details to make decisions on how to best control the flight.”

“Imagine being able to rapidly and affordably convert a general aviation aircraft, like a Cessna or Piper, into an unmanned aerial vehicle, having it fly a mission autonomously, and then returning it back to its original manned configuration,” said Alok Das, an AFRL scientist. “All of this is achieved without making permanent modifications to the aircraft.”

In the case of the A-22 drone, the Ukrainians clearly aren’t worried about uninstalling the autonomous controls. The drone is, in effect, a slow cruise missile. It’s not supposed to return to base.

And as a cruise missile, the A-22 is a real bargain. Counting the price of the new controls and the explosive payload, an A-22 drone might cost a few hundred thousand dollars.

That’s cheaper than Ukraine’s locally-made Neptune cruise missile, which costs around $500,000. And it’s much cheaper than the $3-million Storm Shadow cruise missiles Ukraine has received from the United Kingdom.

As a bonus, an A-22 with its approximately 600-mile range outdistances the Neptune and the Storm Shadow, both of which travel no farther than 200 miles.

The main downside of the sport plane cruise missile is its low speed: at most, 126 miles per hour, compared to the 600 miles per hour a Storm Shadow can sustain.

In theory, that makes an A-22-based drone vulnerable to Russian air defenses. In practice, air defenses are spread thin across the vastness of Russia’s interior. There’s plenty of room for Ukraine’s new cheapo sport-plane drones to roam—and strike.
