Slovak Air-Defence System ‘Wolf 25 AD’ Tested in Ukraine
Slovak company DefTech has confirmed its Wolf 25 AD air-defense system was successfully tested and deployed in Ukraine, offering dual counter-drone and ground-attack capabilities through its 25 mm Oerlikon cannon and AESA radar tracking suite.
BRATISLAVA / KYIV — Slovak defense company DefTech has announced that its Wolf 25 AD short-range air-defense system has completed successful field trials in Ukraine and has reportedly entered service with the Ukrainian Armed Forces.
The Wolf 25 AD, built on the Wolf 4x4 armored platform, is designed as a dual-purpose counter-drone and ground-engagement system, offering both anti-air and anti-armor capabilities. It features the Mangart 25 unmanned turret module developed by Slovenian firm Valhalla Turrets, equipped with a 25 mm Oerlikon KBA autocannon and a 7.62 mm FN MAG machine gun.
The system’s versatility lies in its ability to engage aerial targets—such as drones, loitering munitions, and low-flying helicopters—while also being capable of neutralizing lightly armored ground vehicles. The 25 mm autocannon supports various ammunition types, including armor-piercing, high-explosive fragmentation with proximity fuses, and armor-piercing incendiary rounds. According to DefTech, the fragmentation rounds have an effective lethal radius of around 1.5 meters, making them particularly effective against small UAVs.
DefTech first showcased the system earlier this year at IDET 2025 in Brno, where it drew attention for its role in the growing market for gun-based counter-drone solutions. Shortly after the event, in June, the company announced that a prototype had been sent to Ukraine for evaluation under combat conditions.
In August, DefTech released images of the system in Ukrainian service, claiming it had passed testing “positively” and was already in operational use. The company did not disclose the number of systems delivered, though it confirmed interest from additional export customers. Industry observers suggest the Slovak Armed Forces may also consider the system for domestic use.
The Wolf 25 AD’s AESA radar, operating in the S-band, can simultaneously track up to 150 targets, detecting fighter aircraft at 20 km, hovering helicopters at 12 km, cruise missiles and large UAVs at 10 km, and micro-drones at 5 km. The platform also includes electronic warfare (EW) capabilities for jamming and disrupting hostile UAV communications.
With a 6.7-liter Cummins turbo diesel engine and 6-speed Allison transmission, the Wolf 25 AD combines mobility, protection, and firepower in a single platform—designed to meet the modern battlefield’s need for rapid-deploy, short-range air defense against drones and low-altitude threats.
If confirmed, Ukraine’s adoption of the Wolf 25 AD would make it the latest European-made counter-drone system to enter the country’s inventory, joining a growing list of Western-supplied systems that combine traditional firepower with electronic warfare and radar integration.
