Since our last article/video on gun-armed drones in September 2024, both sides have continued to develop the technology. We’ll be taking a look at the latest develeopments in gun-armed rotor-powered drones in a future article/video, in this video we’re going to take a look at the latest development: a gun-armed fixed wing UAV.
The first imagery of the ‘ZigZag’ UAV developed by Ukrainian drone manufacturer Sky Defenders was shared on social media 15 March. Shared on Sky Defenders’ official social media channels the minute long video shows a fixed wing UAV being launched, once in the sky the video cuts to an onboard camera view which features a crude but unmistakable sighting ring. In the nose of the UAV we can see a pair of tubes set side by side. The video shows a test flight of the twin prop UAV.
This appears to be the second fixed-wing drone developed by Sky Defenders. the first is the Vyryi M7 which is now said to be being delivered to Ukrainian units. The M7 is a loitering, or one-way, munition, powered by a single rear prop it has a 33km range and a warhead in its nose.
In an earlier video shared by a Misha a member of the Sky Defender’s team, posted on 5 March, we get a closer look at the ZigZag gun-armed drone. The video’s caption reads: “Please support the combat tests of the Zigzag interceptor aircraft. This UAV is quite an achievement for my small but really awesome team. We put all our resources into this project.”
The ZigZag has been in development since at least February 2025, with Sky Defenders sharing a short video from flight testing of the drone with the UAV seen without its four guns.
It appears that the drone actually has four rather than two gun barrels. There is only a short clip of the drone’s guns being tested and it doesn’t appear that the drone’s flight is impacted by the recoil of the gun. From the fuselage design it appears that the drone will not be using the counterweight recoilless gun designs used by the quadcopter gun-armed drones. It’s likely the the ZigZag is powerful enough to fire conventional-type ‘shotgun’ and withstand the recoil.
In the video we can see the aiming post and ring and behind it a camera on a 360-degree gimbal mount which enables aiming. While the M7 drone is a one-way-munition and not designed to return the ZigZag appears to be more robust and intended for repeated sorties. The range, weight and loitering time of the UAV is currently unknown. The role of the ZigZag appears to be as a dedicated drone hunter able to rapidly intercept opposing drones and engage them with its guns. It will be interesting to see how the ZigZag is employed.
The Sky Defenders ZigZag represents another interesting step in the rapidly evolving gun-armed drone space in Ukraine.
