Ukraine's Ayudag-6 heavy-lift drone conducts world's first unmanned aerial battlefield medical evacuation.

Ukrainian forces from the 30th, 92nd, and 14th Brigades executed the world's first unmanned aerial battlefield casualty extraction using a Heavy Shot Ayudag-6 hexacopter drone on October 4, 2026, evacuating a severely wounded soldier across the Oskil River in the Kupiansk sector. The mission addressed severe access constraints caused by extensive minefields, Russian FPV drones, and natural water barriers that had previously destroyed an unmanned ground vehicle during a rescue attempt. Designed by Ukrainian manufacturer Gurzuf Defence, the modified six-engine UAV transported the casualty 15 to 16 km suspended beneath its frame as part of a multi-unit operation supported by artillery counter-battery fire and electronic warfare.

On October 4, 2026, Ukrainian forces used a Heavy Shot Ayudag-6 hexacopter drone, manufactured by Gurzuf Defence, to evacuate a severely wounded soldier from the Russian-contested eastern bank of the Oskil River in the Kupiansk sector, in what is believed to be the world's first combat extraction of a wounded serviceman by a multirotor drone. The operation recovered Kostiantyn "Magura" Vlasenko of the 30th Separate Mechanized Brigade, who had remained isolated for 491 days, including more than seven months after injuries that ultimately cost him both feet. Russian FPV drones, extensive minefields, and the Oskil River itself had prevented conventional evacuation, while an earlier attempt using an unmanned ground vehicle (UGV) failed when Russian forces destroyed it.

Therefore, the operation required cooperation between the 30th, 92nd and 14th Brigades, the 10th Army Corps and supporting artillery, reconnaissance and electronic warfare units. The 98 kg drone, capable of lifting 130 kg under test conditions, transported Vlasenko approximately 15 to 16 km suspended beneath its airframe, while the complete mission covered 62 km in 74 minutes and 36 seconds, followed by another 8 km aboard a Peacemaker ground robot. Vlasenko occupied his position from June 2, 2025, initially accompanied by another soldier who was subsequently killed, leaving him isolated in an area monitored by Russian reconnaissance drones and periodically approached by Russian infantry. On February 14, 2026, a Russian drone dropped an explosive munition that injured both legs, ultimately resulting in the loss of both feet and preventing independent movement.

Ukrainian personnel maintained contact by radio and delivered food, water, antibiotics, antiseptics, and painkillers every four to five days, but Russian FPV drones, minefields, and the Oskil River prevented rescue teams from reaching him. After a UGV sent to extract him was destroyed, the 30th Brigade's reconnaissance chief, call sign Alex, contacted Gurzuf Defence to determine whether its developing Ayudag-6 could transport a person. The project required six months of adaptation and preparation, including two months of planning involving approximately 15 military personnel and seven days of immediate mission preparations. Before the extraction, a drone delivered a Petzl Pitagor rescue triangle, carabiners, and a telephone containing a video explaining the attachment procedure, allowing Vlasenko to secure himself to the hexacopter's winch. 

During the mission, operators of Vampire bomber drones diverted Russian attention, losing one drone, while an Autel reconnaissance quadcopter monitored the flight and a Lucky Strike interceptor remained available to provide standby protection against Russian UAVs. Artillery from the 10th Army Corps suppressed identified Russian drone-launch positions, while electronic warfare specialists supported the Ayudag-6's protection. Following the 15 to 16 km airborne segment, Vlasenko was transferred to a Peacemaker ground robot, which traveled 8 km off-road before a vehicle transported him to a stabilization point and subsequently to a military hospital in Kharkiv. The complete 62 km mission lasted 4,476 seconds, corresponding to an overall average of 49.9 km/h, although the actual speed during the casualty-carrying segment was not separately established.

The distinction matters because the evacuation demonstrated an aerial human-transport capability over 15 to 16 km supported by intermediate servicing, rather than an uninterrupted 25 km flight with a 130 kg payload. Moreover, during the October extraction, ground teams changed the batteries at intermediate positions because the Ayudag-6 could not complete the required flight on one battery set while carrying a person. The Ayudag-6 is a six-motor electric hexacopter developed by Gurzuf Defence to transport heavy cargo to frontline positions; its designation refers to Mount Ayu-Dag in Crimea and the number of propulsion motors. Its unloaded mass is approximately 98 kg, while its normal payload capacity ranges from 70 to 90 kg, representing 71.4 to 91.8% of the hexacopter's own weight.

At those loads, the combined aircraft-and-payload mass reaches 168 to 188 kg under normal loads and 228 kg at its demonstrated 130 kg maximum, excluding equipment not included in the empty-weight figure. During May 2026 testing, it lifted 130 kg to 15 meters and maintained that load for 15 minutes, demonstrating a maximum lifting capability 44.4% above its normal upper payload rating. The Ayudag-6 operates at nominal altitudes between 150 and 300 meters and has a stated range of up to 25 km, depending on payload and battery configuration. Different battery sets prioritize lifting capacity or endurance, explaining why intermediate battery changes were required during the evacuation. The complete 62 km mission averaged 49.9 km/h over 74 minutes and 36 seconds, although the casualty-carrying segment represented only 15–16 km of that distance. 

For this casualty extraction, Gurzuf Defence and specialists from the 92nd Separate Assault Brigade modified the Ayudag-6's electric winch, attachment points, and suspension arrangement to reduce oscillation and prevent the drone from becoming unstable under a moving load. Vlasenko traveled in a semi-reclined Petzl Pitagor rescue triangle without an enclosed compartment or protective structure around him, only secured by carabiners, while a dedicated camera allowed the pilot to observe the attachment process and verify that the casualty had secured himself. Starlink satellite connectivity maintained command and control despite Russian electronic warfare activity, with no reported interruption during the mission. Thermal imaging, reconnaissance UAVs, and an alternative return route supported the extraction. However, the external suspension did not protect against fragments, weather, or rotor downwash, and the absence of protective goggles caused discomfort during flight.

The drone also lacked physiological monitoring, oxygen equipment, and in-flight treatment capabilities, making the operation a CASEVAC extraction rather than medically supported MEDEVAC. This distinction is operationally significant because the Ayudag-6 could move a casualty beyond an inaccessible area but could not stabilize a deteriorating patient during the flight. Moreover, a mechanical failure or interception above the Oskil River would have created an additional danger because Vlasenko admitted he could not swim. Nevertheless, the Ayudag-6 substantially increases carrying capacity compared with Gurzuf Defence's earlier Heavy Shot quadcopter, of which Ukraine received 206 units in October 2023. Those earlier drones carried up to 40 kg over an operating radius of 20 km, could transport 60 to 120 mm mortar ammunition, and incorporated GPS navigation, automatic return, 30× optical zoom, and electronic warfare protection.

The Ayudag-6's normal payload represents a 75 to 125% increase, while its demonstrated 130 kg lift exceeds the earlier maximum by 225%. Gurzuf Defence began human-lift experimentation in March 2024 and completed the 130 kg lifting demonstration in May 2026. Although developed primarily for ammunition, food and equipment transport, production Ayudag-6 drones will now incorporate winch mounting provisions and emergency evacuation attachments. The 130 kg lifting limit nevertheless restricts the combined weight of casualties, protective equipment and medical devices, while higher-capacity variants remain under development without confirmed delivery schedules. Heavy Shot drones have also been used for humanitarian supply, robotic vehicle transport, and FPV drone deployment.

In September 2026, Heavy Shot and other heavy-lift UAVs transported approximately 4,000 kg of food across the Dnipro River to civilians in Russian-occupied Oleshky. Heavy Shot drones also supplied Ukrainian positions at Krynky, where Russian fire restricted conventional transportation. During Operation Vivaldi, they carried unmanned ground attack vehicles more than 10 km into Russian rear areas, allowing the UGVs to continue independently toward Russian positions located 15 to 20 km beyond the line of contact. The drone family has additionally transported smaller FPV drones before releasing them for independent flight, extending the range of missions achievable without exposing ground vehicles to the initial transport route. Ukraine's SkyFall StarGate and Europe's Grille now represent two alternative approaches to unmanned casualty evacuation, with higher stated payload capacities than the Ayudag-6.

The StarGate carries up to 150 kg over a stated one-way distance of 15 km, exceeding the Ayudag-6's demonstrated lift by 15.4%, and entered frontline testing in October 2026. The Grille, developed under the European Defence Fund's iMEDCAP program, has a stated 175 kg payload and 50 km range, exceeding the Ayudag-6's demonstrated capacity by 34.6%, without establishing equivalent endurance at maximum load. Two personnel can prepare the Grille from its transport configuration in approximately 15 minutes. Initiated in 2023 with 24 partners from nine countries, iMEDCAP combines thermal-imaging UAVs, radar-based breathing detection, THeMIS ground robots using LiDAR and inertial navigation, and patient transport equipment supporting physiological monitoring and remotely supervised treatment.

Its integrated evacuation concept was demonstrated with simulated casualties during Vigorous Warrior 2026 in Estonia, whereas the Ayudag-6 has completed an actual combat extraction. The Kupiansk evacuation also illustrates a change in Ukrainian casualty evacuations, as FPV drones, loitering munitions and minefields increasingly restrict vehicle access to forward positions. Vlasenko remained without conventional medical evacuation for 232 days after his February 14 injury, despite repeated drone deliveries of antibiotics, antiseptics and painkillers, demonstrating the gap between sustaining an isolated casualty and providing surgical treatment. The October operation bridged that gap through 15–16 km of aerial transport, 8 km of robotic ground movement and subsequent conventional evacuation, establishing a 23–24 km unmanned transport segment.

This approach introduces an additional CASEVAC echelon where helicopters and ambulances cannot operate, but it does not replace the Golden Hour objective of obtaining advanced medical care within 60 minutes. Its limitations remain substantial: Vlasenko was conscious and able to attach his own harness, while unconscious patients or casualties with uncontrolled hemorrhage would require additional assistance and medical equipment. The next operational requirement is therefore not simply greater lifting capacity, but reducing mission preparation time, protecting casualties during transport, and integrating medical monitoring into future unmanned evacuation systems.
